Freeze Protection If the unit is installed in a location subject to freezing conditions, it is important to protect the water circuit from freezing, just as should be done for the pump and filter. System Drain-Down 1. Turn the unit circuit breaker or disconnect switch to OFF. 2. With the pool pump OFF, close the external shutoff valves and loosen the inlet and outlet water unions to allow water to drain. Use a Wet/Dry Vac or air pressure to remove excess water. 3. Loosely re-attach the unions. 4. Cover the unit with a waterproof cover. Continuous Pump Operation It is also possible in some areas to prevent unit freeze damage by operating the pump continuously during freezing weather. However, this results in significantly higher pump operating costs. Further, if a sustained power failure occurs, the unit MUST be drained anyway, or freeze damage could result. Maintenance NOTE: The heat pump pool heater MANUFACTURER IS NOT RESPONSIBLE for maintenance adjustments. The following maintenance procedures are designed to keep your unit operating at a high level of reliability. Maintenance must be performed on a periodic basis to maintain warranty coverage and prevent system failures and performance degradation. Air Coil Cleaning Efficient operation depends on free circulation of air through the thin and tightly-spaced fins of the evaporator coil(s). The evaporator must be cleaned whenever it has a buildup of dirt or debris. CAUTION: To clean the fins, spray gently with a garden hose. DO NOT pressure wash. Doing so will bend the fins and can void the warranty. Cabinet Care (optional) The cabinet is designed for outdoor use and requires little care. However, you can clean it if you wish. Wash the cabinet with soap and water. WARNING: Shut OFF electricity to the unit before cleaning. Unplug Condensation Drain Holes The unit extracts humidity from the air as it passes through the coil, similar to the way a cold drink outside “sweats” on a hot day. This condensation drains from the bottom of the unit. 1. Routinely check to be sure the condensation drain holes in the base of the unit are not plugged with dirt or debris. 2. If condensation becomes a problem, optional drain pans are available from your heat pump pool heater distributor or pool dealer. 9 Troubleshooting If your unit does not operate, or simply does not heat your pool water, Fault Codes on the front control panel, can provide valuable clues as to what is wrong, and may even indicate precisely what the problem is. Always observe these codes before calling a service representative. By reporting on the telephone the Fault Codes that are showing, the service rep may be able to solve the problem without the expense of a service call. A. UNIT IS RUNNING, BUT NOT HEATING • Is water flow through the unit adequate? Check the unit for obstructions, such as a clogged filter pump strainer, a dirty filter, or valves not positioned correctly. • Is the ejected air from the unit 8°–10°F cooler than incoming air? If so, the unit is extracting heat from the air and transferring it to the pool. • Is water condensing on the evaporator and internal copper pipes? This is also evidence of heat removal from the air. When the air is cool with low humidity, condensation may not be evident. • How long has the unit been operating? During initial pool heating i...
