See below for water temperature guidelines before setting temperature. 1. Spa or hot tub Water temperatures should never exceed 104' F. A temperature of 100' F. is considered safe for a healthy adult.Special caution is suggested for young children.Prolonged immersion inhot watercan induce hyperthermia. I Drinking of'alcoholic beverages before or during spa or hot tub use cwi cause drowsiness which could lead to unconsciousness and subsequently result in drowning. 3, Pregnant women beware! Soaking in water above 100° F. can cause fetal damage during the first three months of e:1 - pregnancy(resulting in the birth of a brain-damaged or deformed child). Pregnant women should stick to the 100'F, maximum rule. 4. Before entering the spa or hot tub, the user should check,. the water temperature with an accurate thermometer, Spa Or hot tub thermostats may err in regulating water temperatures by as much as 4' F. i. Persons with a medical history of heart disease, circulatory problems, diabetes or blood pressure problems should obtain their physician's advice before using spas or hot tubs. 6, Persons taking medication which induce drowsiness,such as tranquilizers,antihistamines or anticoagulaots should not use spas or hot tubs. AWARKING Should overheating occur or the gas supply fall to shut off,turn off the manual gas control valve to the heater. Do not use this heater if any part has been under water. Immediately call a qualified service technician to inspect the heater and to replace any part of control system and gas control which has been under water. PIN 472592 Rev.0 10-5-07 x Section 2.

The heater, when installed, must be electrically grounded and bonded in accordance with local codes or,, in the absence of local codes,with the National Electrical Code or the Canadian Electrical Code(as applicable).A bonding lu-C,is provided on the outside of the panel under the vent for this purpose. 3, Electrical powercircuits to the pool heater must follow local codes and National Electrical Code or Canadian Electrical Code(as applicable). 4. All wiring between the heater and devices riot attached to it,or between separate devices which are installed in the field,must be"Type'l`wire rated.for 35°C>rise. 5. All line voltage wiring shall be enclosed in approved I'lexible conduit,and shall be securely attached to the field wiring i)ox located inside the access door panel.The conduit or cable connector at the field wiring box should contain an insulating bushing or its equivalent to prevent abrasion of the wires as they enter the box, 6. The filter pump should run continuously when the heater is on,and for at least 15 minutes after the heater turns off.Any switches in the pump circuit(including circuit breakers) that can disconnect tile pump must also disconnect the healer. 7. Do not wire single-pole switches, including protective devices, into a grounded line.The heater is not sensitive to polarity. Connect the Ll of the power supply to the black wire..the L2 or neutral lead to the red wire,and the ground wire to the green wire.A.time clock controlling the filter pump should have a low-voltage Fireman's Switch that switches off the heater at least 15 minutes before shutting off the pump. Always use critnj.� �j?pe connectors when connecting lu"o wirt!s. AC Plug . 120 Volt or 240 Volt Figure 20. P/N 472592 Rev.C 10-5-07 Section 3.
