Introduction Conforms to HUD MHCSS 10/20/08 This installation manual contains instructions that must be followed for the proper installation of the home. It complies with the HUD Model Manufactured Home Installation Standards. Please read all instructions and any other documents (includ- ing addendum pages and supplements) that may apply to the specific home prior to commencing site work or installation. This installation manual covers permits and site work through final inspection of the installation. It covers both single and multi -section homes installed over pier and anchor, load bearing crawl space walls and basement foundations. It contains instructions, including specifications and procedures, for the set and hookup of manufactured homes to be used as single- family dwellings. The importance of correct installation cannot be over -emphasized. Correct installation is absolutely essential to home- owner satisfaction and the structural integrity of the home. All instructions must be followed to provide the customer with a safe, quality home. l No manual can cover all circumstances that may exist for certain home designs or building sites. For questions, further clarification, or if you encounter conditions at the site or in the design of the home or its foundation not covered by this manual, please contact the manufacturer (see ;Resources, p. 2), a registered engineer, or registered architect. Supplemental addendum pages may be included with this manual. Supplements include requirements not covered in this manual or that supercede the manual instructions. Once the home installation is complete, leave this manual with the home. IMPORTANT NOTICES • The home manufacturer is not respor sible for installation or for the materials supplied by the set-up crew at the time of installation. The installer may be responsible for any deviations from the installation instructions of this manual. • To keep the home in compliance with its warranty, the home installation must follow the procedures described in this manual or other procedures approved by the manufacturer. Deviation from the instructions in this manual may void the home's warranty. Any alterations or changes to the home shall be approved by a registered engi- neer or registered architect and may (sItill be subject to warranty violations. • When an installer does not provide silpport and anchorage in accordance with the approved manufacturer's in- stallation instructions, or encounters site conditions (such as areas that are subject to flood damage or high seismic risk) or other conditions that prevent the use of the instructions provided in this manual, the installer must obtain special site -specific instructions from the manufacturer or use a design approved by a registered engineer or registered architect. • The installer must possess a valid installation license as a manufactured home installer. • If the installer identifies failures of thelhome to comply with the Federal Manufactured Home Construction and Safety Standards (the HUD Code), the installer must notify the manufacturer and retailer. SAFETY There are potential hazards associated with the installation of a manufactured home. Home installers are licensed, and as experienced professionals, should recognize tFlese hazards, be qualified to work with them, and be capable of providing safe work practices and equipment that minimize the risks of injury. Only qualified persons should install a manufactured home. As qualified professionals in the field of manufactured home installation, installers are the experts and must lbe aware of the hazards and conditions faced. Warnings are published throughout this manual as reminders. These reminders may not cover all hazards, all potential hazards, or all possible consequences of improper or unsafe installation practices. Construction crews should be trained in the skills required and be supervised by experienced personnel. Installers should regularly inspect work performed by crews and subcontractors.

PLAN SITE ACCESS Planning the route to the site is typically the responsibility of the retailer or transporta- tion company. Whoever is responsible must secure state permits from the states through which the home will pass. In planning the route, avoid obstructions that might interfere with the passage of the home, such as low hanging wires and trees, low overpasses, and bridges not suitable for the load. Contact the utility company if wires need to be moved. Do not allow branches, bushes, or other foliage to scrape against the home as the home is moved to the site. Avoid ditches, berms, steep slopes, and soft ground. Identify and fill any holes and soft spots into which the transporter's wheels may sink. Avoid moving over steep changes in grade (20 degrees or more). If required, provide for home storage and staging areas on the site. Plan the delivery and staging of home sections and materials so that after all deliveries are complete, home sections and materials can be accessed for use and installed in the appropriate sequence. Orient home sections so they do not have to be rotated or excessively ma- neuvered during the installation process. Plarl for temporary needs, such as dump- sters, portable toilets, crew parking, delivery lehicle drop-offs and concrete mixer de- liveries. Before moving the manufactured home to the' site, inform the LAHJ and make sure the site is prepared and utilities are available. STEP 2. DETERMINE HOME LOCATION AND LAYOUT The home location may have already been determined by others. If not, plan the home location and layout in compliance with the regulations researched in Getting Started, STEP 5. CHECK LOCAL CODES AND SECURE PERMITS (p. 7). Contact utilities for locations of existing infrastructure, such as underground cables, pipes, and electrical lines. When planning the site improvements, consider the following: • The home location should be level. • Avoid contact with large trees, steep slopes, poorly drained areas, and poten- tial flood zones. • Preserve trees and shrubs for shade, visual screens, and windbreaks. • Plan the driveway, parking areas, septic, well, other structures, and utility lines. m Harbor Homes, Inc. %r&JFZZA Site Preparation.

A soil's bearing capacity can be greatly reduced when it is saturated with water. Note that water, tables may vary with seasonal or cli- mactic conditions. Consult a geologi t or the LAHJ if you are unsure of the water table level. • The soil must not be a highly expansive type. Expansive soils can expand when they become saturated with water, causing the home to shift and be- come unlevel. If soils are expansive, contact a registered engineer, or regis-r tered architect to assist with the design of the foundation system. STEP 5. DETERMINE SOIL -BEARING CAPACITY AND FROST LINE The soil under a home must be capable of withstanding the loads imposed by the weight of the home, its support system and fur Irishings, as well as any loads imposed by wind, snow, or other climactic conditions. SOIL -BEARING CAPACITY Determine the soil -bearing capacity in pounds per square foot (psf) before designing a support system. The higher the capacity (psf), the more weight the soil can hold without unduly compressing. As the soil -bearing capa pity increases, footings can be reduced in size or spaced farther apart. I Use one or more of the following methods to determine the site's soil bearing capacity: • Test the soil. Hire a registered geologist, registered engineer, or registered architect to determine the soil classification and maximum allowable soil bear- ing capacity by testing the soil in accordance with generally accepted engi- neering practice. • Obtain soil records. The local office of the U.S. Department of Agriculture's Natural Resources Conservation Service (www.soils.usda.gov) and/or the LAHJ may have test results and/or soil analyses on file for the area. • Conduct a pocket penetrometer test. Use a pocket penetrometer to esti- mate allowable soil -bearing capacity as follows: 1. Select a location that will be unc 2. Clear an area of a minimum of c or to the depth of the bottom of I 3.

If one of the options above is not available, the values on 'able 4 can be used to establish soil - bearing capacity by visual examinatioi. This method provides lower capacity values than the options above. Accurate soil identification typically requires special training or expertise.

Limitations of pocket pene- trometers. Pocket pene- trometers do not work on sand or gravel. Use Table 4 to determine allowable pressure for these types of soils. If you encounter a layer of gravel, test the soil under the gravel. Do not put the penetrometer on stones larger than its tip as this will provide an inaccu- rate reading.

Conforms to Install Footings 0085s This chapter provides instructions for the design and construction of individual footings that transfer the load from a single pier to the ground. A footing and pier together (discussed in Set the Home) is referred to as a "support." A footing may also be designed to carry the load of multiple piers (often called "strip" footings).

DETERMINE LOCATIONS Point loads exist where a bearing/structural weight is concentrated and transferred to the foundation at a specific point. Locate a support under each point load, including the following examples: i • Exterior doors on side walls at both sides of each door (blocking is not re- quired at exterior doors on non -bearing end walls). • Other exterior wall openings four feet and greater at both sides of each open- ing (including multiple windows that total four feet wide or more without inter- mediate supports, even if individual windows are less than four feet). • Marriage line openings four feet or greater at both sides of each opening (where marriage line openings are greater than 10 feet, intermediate supports must be placed at maximum 10 feet on center). • Locations where through -the -rim crossover ducts penetrate the rim joist at the marriage line (unless otherwise noted in supplemental documents provided with the home or unless the home is constructed with a perimeter frame sys- tem). • Marriage line columns. • Load -bearing porch posts. • Under heavy (400 Ibs or greater) items, such as heavy furniture, waterbeds, fireplaces and large fish tanks when located outboard of the home's main (- beams.

Conforms to Construct Foundation "10 oog Ss (FOR HOMES WITH LOAD -BEARING PERIMETER WALL) This chapter provides guidelines and recommendations for the design and construction of a basement or crawlspace foundation using a load -bearing perimeter wall. A load -bearing perimeter wall foundation system uses a wall along the outer edge of the home to support the home's outside walls. This perimeter support works with interior supports such as piers, columns, and cross beams that support the home's frame and, if multi -section, marriage line. STEP 1.

Leave room for a two-inch nominal, pressure treated wood spacer on top of the wall pockets (to prevent corrosion, the steel beams must not be in direct contact with concrete). Leave at least one inch for thermal expansion at the ends of the beams and maintain a minimum of two inches of bearing area for the beams in the pockets (yielding a minimum pocket depth of three inches). Bolt a pressure treated wood sill plate (minimum 2 x 6) to the top of the foundation wall. If the home's siding cannot be nailed throdw, use a 2 x 10 sill plate that extends into the foundation 1-1/4 inches (Figure 16). The home can then be connected to the foundation by fastening the sill plate into the floor joists from below. Connect the home to the foundation according to the approved design.

The system covered here uses earth (or ground) anchors and steel straps connected to the home's longitudinal steel beams and/or exteriorl walls. Stabilizer plates may also be used to prevent the anchor head from moving laterally in the ground. An anchor, strap', and stabilizer plate (if used) together are referred to as a tie -down. Anchors can also be mounted in concrete footings when there is enough concrete mass (weight) to resist the lateral and upward forces. This type of system is not covered in this manual. ® STEP 1.

SIDEWALL VERTICAL ANCHORS Homes designed for Wind Zones II and III also require vertical tie -downs along the sidewalls. The vertical tie -down anchor strap6 (or brackets for connecting to the home) are factory installed and indicate the locations. Vertical and frame sidewall tie -downs may connect to one double -headed anchor or each to its own dedicated anchor. Any factory -installed sidewall tie -down straps must be connected to a ground anchor regardless of the wind zone in which the home is placed. END WALL FRAME ANCHORS End wall frame tie -downs are especially important for homes that are wider and have higher roof pitches because those features increase the surface area exposed to wind loads at the ends of the home. Use Table 25 to determine the number of end wall frame anchors required at the each end of each home section. Palm Harbor Homes recommends the use of Longitudinal Stapilizing Devices (LSD) or other ap- proved systems. These devices or systems are NOT provided by Palm Harbor Homes. Companies, such as Tie -Down Engineering, Inc., and other manufactur- ers, may be contacted to obtain such devices. Table 25 is based on Tie -Down Engineering's LSD system.

Anchors must be tel and listed to resist a minimum ultimate load of 4,725 Ibs and a minimum allowable working load of 3,1i50 Ibs or ultimate and corresponding working load limited by soil conditions and anchor length. The working load is the maximum load the designer can use.

INSTALL ANCHORS Before beginning anchor installation, check for obstructions under the home such as piers and frame members that may interfere with the tie down strapping. Check with utility companies to determine the location of u , derground utilities, such as electrical and phone lines, and water, sewer, and gas pipes that may be buried in potential an- chor locations. Also check for homeowner -installed wires and pipes, such as those connecting exterior lighting or sheds to the ho ie. These must also be avoided. FRAME ANCHORS Frame anchors can be installed in two ways, in -line and against a stabilizer plate. The two methods are discussed below: In -Line Configuration The in -line configuration (Figure 67) for homes can be used in Wind Zone I only. Typi- cally, in -line anchors are used under high homes where the anchors can be installed from under the home after the home is set. In -line anchors can also be installed before the home is set, however, precisely aligning they anchor with the home both vertically and horizontally is difficult. Using swivel connectors for the strap to beam connection can provide some horizontal flexibility. To install in -line frame anchors, drive the ancho into the ground at an angle and loca- tion such that a straight line can be drawn from �he tip of the anchor through the anchor head and to the connection point on the 1-beam (Figure 68). Stabilizer Plate Configuration Stabilizer plate configurations (Figure 68) are suitable for homes in all wind zones. An- chors may be installed after the home is set. A stabilizer device, typically an ABS or metal plate, is used to prevent the top of the anchor from slicing through the soil when the load is applied. Stabilizer plates are available in a variety of widths. Choose the widest plate that can be driven into the soil to maximize resistance to movement. The LAHJ may have stabilizer plate requirements. Install anchors with stabilizer plates as follows: 1. Locate anchor. Select a location for the anchor under the home but within six inches of the exterior wall (Figure 69). Avoid locations that will interfere with skirting. 70 Palm Harbor Homes, Inc. to 10/20/08 Grading area around anchors. Anchor heads should not rest in sunken spots. Grade the ground so that water does not collect around anchor heads, but runs away from the anchor and out from under the home. Do not bury anchor heads. Figure 67.

CONNECT ELECTRICA,L SERVICE The home is designed for connection to an electrical wiring system rated at 120/240 volt AC. All electrical field work must be done by a licensed electrician or other person approved by the LAHJ. FEEDER WIRE AND EQUIPMENT SIZES The current rating (in amperes) of the home can be found on the tag located on the outside next to,the feeder or service entrance, and on the electrical distribution panel. Using this information, determine the required feeder wire size from Table 34. These sizes are based on an ambient temperature of 86 degrees Fahrenheit and do not take voltage drop into consideration. Acceptable conductor types are: RHH, RHW RHW-2, THHN, THHW, THW, THW2, THWN, THWN-2, XHHW, XHHW-2, SE, USE, and USE-2. TABLE 34.

Installation of the electric power to the home can cause exposure to live electrical circuits. Exposure to live electrical circuits or improper grounding of the conductor in the panel board may result in severe shock or possible electro- cution. A qualified installer must make the connections for the electric power. 9/22/08 Palm Harbor Homes, Inc. 75 PFS ceitifies this document is current as of 11/03/14. to W. 10/20/08 FEEDER CONNECTIONS Feeder connections are made from above or from below the home as follows: From above — mast weatherhead feeder The routing, connection, and support of the service drop must meet local codes. Homes equipped this way contain all necessary' conduits to the electrical distribution panel. However, the feeder conductors (not provided with the home) are installed on site. If the masthead is located above the roof oyerhang, allow a minimum clearance of eight feet above all roof points that the conductors pass over. There are two exceptions to this rule: (1) The vertical clearance may be reduced to three feet if the roof has a minimum slope of 4 in 12; and (2) The vertical clearance may be reduced to 18 inches if no more than four feet of service -drop conductors pass above the roof overhang, and if they terminate at a through -the -roof raceway or approved support. A minimum clear- ance must also be provided from the final grade to the service -drop conductors. This measurement may vary from 10 feet to 18 feet, depending on the types of traffic antici- pated below the service drop (refer to the NEC). Unless impractical, locate service heads above the point of attachment of the service -drop conductors and make them rain -tight. If individual conductors do not extend downward, form drip loops. From below — underside junction box feeder A section of conduit is factory installed through the floor cavity. Connect to that conduit with approved fittings and conduit (not provided) with the home) to the point where the service entrance cable enters the crawl space. Install properly -sized service entrance conductors from the main power supply to the panel board. Depending on the location of the main panelboard inside the home, or the point at which the service entrance conductors enter the crawl space, a separate service disconnect may be required. Re- fer to Table 34 for the conductor and junction box requirements. The installer must provide the supply connection including the feeder conductors, junction box, and con- duit connectors. Protect conductors emerging from the ground from a minimum of 18 inches below grade to eight feet above grade, or to the point of entrance to the home. The distance measured from the top surface of a buried cable, conduit, or raceway to the finished grade must meet the minimum burial requirements outlined in the NEC. Use a moisture -proof bushing at the end of the conduit from which the buried cable emerges. i GROUNDING The home must be properly grounded to protect the occupants. The only safe and ap- proved method of grounding the home is througan electrically -isolated grounding bar in the manufactured home distribution panel board. This grounds all non -current - carrying metal parts to the electrical system in tale home at a single point. Each neutral conductor must be connected to the system grounding conductor on the the supply side of the main disconnect in accordance with Articles 250.24, 250.26, and 250.28 of the National Electrical Code, NFPA No. 70-2005. Where the meter base has a disconnect (typically when the meter is more than 6 feet from the -service electric panel, although this may vary by LAHJ) the ground and neutral should be bonded at that disconnect and then grounded to the driven earth ground. Four wires will leave the service electric) panel to the disconnect. Three wires will enter the disconnect from the meter base (refer to Figure 75). Where there is no disconnect on the meter base or between the meter base and ser- vice electric panel (typically when the meter is within 6 feet from the service electric panel, although this may vary by LAHJ), the main circuit breaker in the service electric panel becomes the first disconnect. In this case„the neutral and ground are bonded in the service electric panel and connected to the driven earth ground from the service electric panel. Three wires lead between the meter base and the service electric panel (refer to Figure 76). Power supply. A large enough power supply must be available at the site. An inadequate power supply may result in improper op- eration of and possible damage to motors and ap- pliances. It may also in- crease electricity costs. i ®/ Grounding the electrical system. Do not provide electrical power until the grounding electrode is in- stalled and connected. When the meter base is not on the house never use the neutral conductor of the feeder cable as a ground wire.

Such pressure loss could cause the water heater to drain, exposing the heating elements of electric water heaters caus- ing them to fail. Figure 79. Water heater drip pan and drain 79 PFS this document is current as of 11/03/14. Insulate. In areas subject to freezing'temperatures, protect with insulation or heat tape pipes, valves and pressure, reducers that are exposed to the out- doors; and pipes in water heater compartments with non -insulated doors. Connect heat tape to the electrical outlet under the home near the water sup- ply inlet. TESTING After testing the electrical system and connecting the water lines check the water sys- tem for leaks using one of the procedures described below. Before testing, close all water faucets, spigots, and toilet -tank float valves. Hydrostatic (preferred): 1. Bypass water heater. Bypass the hot water heater by disconnecting the hot outlet and cold inlet water lines from the water heater and joining them to- gether. This will protect the hot water ltank from damage and protect those in- volved in the test from possible injury: 2. Fill water heater. Confirm that the water heater tank is full of water. 3. Pressurize system. Connect a hydrostatic pump, valve, and gauge to the lo- cation shown in Figure 78. Pressurize the system with water at 100 psi, and then isolate it from the pressure source. Bleed all air from the highest and far- thest points in the system. 4. Hold pressure. Monitor the pressure for at least 15 minutes. 5. Fix leaks. If the pressure drops below 100 psi, locate and correct any leaks by cutting out and discarding bad pipe sections or joints and installing new pipe or joints with couplings. 6. Repeat. Repeat the test until all leaks) have been eliminated. Pneumatic: 1. Bypass water heater. Bypass the hot water heater by disconnecting the hot outlet and cold inlet water lines from the water heater and joining them to- gether. This will protect the hot water tank from damage and protect those in- volved in the test from possible injury. 2. Pressurize system. Connect an air pump and pressure gauge to the water inlet, pressurize the system to 100 psi,and isolate the pressure source from the system. 3. Hold pressure. Monitor the pressure for least 15 minutes. If the pressure drops below 100 psi, locate any leaks by applying soapy water to the connec- tions and looking for bubbles. 4. Fix leaks. Correct any leaks by cutting out and discarding bad pipe sections orjoints and installing new pipe orjoints with couplings. 5. Retest. Repeat the procedure until all leaks have been eliminated. 6. Restore connections. Reconnect the, water heater and the water supply. FREEZE PROTECTION FOR UNOCCUPIED HOMES If the home is to be left unheated in cold weather, protect water lines from freezing as follows: 1. Disconnect supply. Turn off the water supply and disconnect the water sup- ply inlet. 2. Drain water heater. Turn off the wated heater; if necessary, attach a hose to the valve to direct water away from under the home, open the drain valve and drain the tank completely. 3. Drain faucets. Open all faucets throughout the home (including the laundry area if plumbed, and any exterior faucets) and let them drain completely. 4. Drain toilets. Flush toilets and drain water tanks completely. 5. Close faucets. Close all water faucets with the exception of one. 6. Connect compressor. Connect a maximum of 30 psi air supply to the water inlet connection using a low pressure compressor. 7. Open faucets. With the air supply on the system, open one faucet at a time throughout the home. i Palm Harbor Homes, Inc. 80 HUD MHCSS 10/20/08 V&*IrZZA Selecting heat tape. Use only pipe -heating cable (tape) listed for manufac- tured homes, and install it in accordance with the ca- ble (tape) manufacturer in- stallation instructions. Testing water lines. Only use pneumatic (air) testing when hydrostatic testing is not practical. Air under pressure is explosive. Ex- ercise extreme caution and notify all site personnel of the test. Wear protective eyewear and take precau- tions to prevent impact damage to the system while the test is in progress. Do not pneumatically test CPVC systems. Pneumati- cally test Flow Guard Gold systems only at low pres- sure levels (20 psi or less). Pressurizing water lines.
