FEATURES / BENEFITS
A PERFECT BALANCE BETWEEN
BUDGET LIMITS, ENERGY SAVINGS AND
COMFORT.
The DHMSHA series ductless systems are a matched combination
of an outdoor condensing unit and an indoor fan coil unit
connected only by refrigerant tubing and wires.
The fan coil is mounted on the wall, near the ceiling. This selection
of fan coils permits creative solutions to design problems such as:
Add-ons to current space (an office or family room
addition)
Special space requirements
When changes in the load cannot be handled by the
existing system
When adding air conditioning to spaces that are heated
by hydronic or electric heat and have no ductwork
Historical renovations or any application where
preserving the look of the original structure is essential.
The ideal compliment to your ducted system when it is impractical
or prohibitively expensive to use ductwork.
These compact indoor fan coil units take up very little space in the
room and do not obstruct windows. The fan coils are attractively
styled to blend with most room decors. Advanced system
components incorporate innovative technology to provide reliable
cooling performance at low sound levels.

LOW SOUND LEVELS
When noise is a concern, the ductless systems are the answer. The
indoor units are whisper quiet. There are no compressors indoors,
either in the conditioned space or directly over it, and there is
none of the noise usually generated by air being forced through
ductwork.
SECURE OPERATION
If security is an issue, outdoor and indoor units are connected only
by refrigerant piping and wiring to prevent intruders from crawling
through ductwork. In addition, since the outdoor units can be
installed close to an outside wall, coils are protected from vandals
and severe weather.
FAST INSTALLATION
This compact ductless system is simple to install. A mounting
bracket is standard with the indoor units and only wire and piping
need to be run between the indoor and outdoor units. These units
are fast and easy to install ensuring minimal disruption to
customers in the home or workplace. This makes the DHMSHA
ductless systems the equipment of choice, especially in retrofit
situations.
SIMPLE SERVICING AND MAINTENANCE
Removing the top panel on outdoor units provides immediate
access to the control compartment, providing a service technician
access to check unit operation. In addition, the draw-thru design of
the outdoor section means that dirt accumulates on the outside
surface of the coil. Coils can be cleaned quickly from the inside
using a pressure hose and detergent.
On all indoor units, service and maintenance expense is reduced
due to easy-to-use cleanable filters. In addition, these high wall
systems have extensive self-diagnostics to assist in
troubleshooting.
BUILT-IN RELIABILITY
Ductless system indoor and outdoor units are designed to provide
years of trouble-free operation.
The high wall indoor units include protection against freeze-up
and high evaporator temperatures on heat pumps.
The condensing units on heat pumps are protected by a three
minute time delay before the compressor starts the over-current
protection and the high temperature protection.
INDIVIDUAL ROOM COMFORT
Maximum comfort is provided because each space can be
controlled individually based on usage pattern. The air sweep
feature provided permits optimal room air mixing to eliminate hot
and cold spots for occupant comfort. In addition, year-round
comfort can be provided with heat pumps.
ECONOMICAL OPERATION
The ductless system design allows individual room heating or
cooling when required. There is no need to run large supply-air
fans or chilled water pumps to handle a few spaces with unique
load patterns. In addition, because air is moved only in the space
required, no energy is wasted while air moves through the ducts.
EASY-TO-USE CONTROLS
The high wall units have microprocessor-based controls to provide
the ultimate in comfort and efficiency. The user friendly wireless
remote control provides the interface between the user and the unit.
ACCESSORIES
Customizing these ductless systems to your application is easily
accomplished.
Adding a condensate pump accessory to the high wall fan coil
provides installation flexibility.

APPLICATION DATA
UNIT SELECTION
Select equipment that either matches or is supports slightly more
than the anticipated peak load. This provides better humidity
control, fewer unit cycles, and less part-load operation.
For units used in spaces with high sensible loads, base equipment
selection on unit sensible load, not on total anticipated load. Adjust
for anticipated room wet bulb temperature to avoid undersizing the
equipment.
UNIT MOUNTING (INDOOR)
Refer to the unit’s installation instructions for further details.
Unit leveling - For reliable operation, units should be level in all
planes.
Clearance - Provide adequate clearance for airflow (see Fig. 6).
Unit location - Select a location which provides the best air
circulation for the room. These units should be positioned as high
as possible on the wall for the best air circulation. The unit return
and discharge should not be obstructed by furniture, curtains, or
anything which may cause unit short cycling or air recirculation.
Place the unit in the middle of the selected wall (if possible). Use
an outside wall, if available, to make piping easier, and place the
unit so it faces the normal location of room occupants.
UNIT MOUNTING (OUTDOOR)
Refer to the unit’s installation instructions for further details.
Do not install the indoor or outdoor units in a location with special
environmental conditions. For those applications, contact your
Carrier representative.
MOUNTING TEMPLATE
Refer to the unit’s installation instructions for further details.
The fan coil units are furnished with mounting to mark the location
of the wiring, and the refrigeration line hole locations.
SUPPORT
Adequate support must be provided to support the weight of all
the fan coils. Refer to the Physical Data section for fan coil
weights, and the base unit dimensional drawings for the mounting
bracket locations.

accessory condensate pump. The high wall fan coil unit condensate
pumps have a maximum lift of 10’ (3.05 m) for 9k and 12k units
and 25’ (7.62 m) for 18k and 30k units.
See the physical dimension tables for the drain sizes.
NOTE: High wall fan coil units have internal condensate traps.
A trap is not required.

WIRING
All wires must be sized per NEC (National Electrical Code) or
CEC (Canadian Electrical Code) and local codes. Use Electrical
Data table MCA (minimum circuit amps) and MOCP (maximum
over current protection) to correctly size the wires and the
disconnect fuse or breakers respectively.
Per the caution note, only stranded copper conductors with a 600
volt insulation rating wire must be used.
Recommended Connection Method for Power and
Communication Wiring:
The main power is supplied to the outdoor unit. The field supplied
14/3 stranded wire with ground with a 600 volt insulation rating,
power/communication wiring from the outdoor unit to indoor unit
consists of four (4) wires and provides the power for the indoor
unit. Two wires are line voltage AC power, one is communication
wiring (S) and the other is a ground wire. Wiring between indoor
and outdoor unit is polarity sensitive. The use of BX wire is NOT
recommended.
If installed in a high Electromagnetic field (EMF) area and
communication issues exists, a 14/2 stranded shielded wire can be
used to replace L2/N and (S) between outdoor unit and indoor unit
landing the shield onto ground in the outdoor unit only.
CAUTION!
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Wires should be sized based on NEC and local codes.
Use copper conductors only with a 600 volt insulation
rating wire.
CAUTION!
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage
or improper operation.
Be sure to comply with local codes while running wire from
the indoor unit to the outdoor unit.
Every wire must be connected firmly. Loose wiring may cause
the terminal to overheat or result in unit malfunction. A fire
hazard may also exist. Ensure all wiring is tightly connected.
No wire should touch the refrigerant tubing, compressor or
any moving parts.
Disconnecting means must be provided and shall be located
within sight and readily accessible from the air conditioner.
Connecting cable with conduit shall be routed through the
hole in the conduit panel.
CONTROL SYSTEM
The indoor unit is equipped with a microprocessor control to
perform two functions:
1. Provide safety for the system
2. Control the system and provide optimum levels of comfort
and efficiency.
The main microprocessor is located on the control board of the
fan coil unit (outdoor units also have a microprocessor) with
thermistors located in the fan coil air inlet and on the indoor coil.
Heat pump units have a thermistor on the outdoor coil. These
thermistors monitor the system operation to maintain the unit
within acceptable parameters and controls the operating mode.
