The compressor will shut OFF but the fan will continue to run. Delay Timer: Prevents compressor from short cycling, which could damage or destroy the hermetic motor/compressor. Upon water temperature control satisfaction, or other circuit interruptions, this solid state device will prevent compressor restart for approximately 5 minutes. Refrigerant Low Pressure Control: Stops the compressor and fan if refrigerant suction (low side) pressure falls too low as a result of a malfunction or loss of charge. Indicator Lamps: There are 3 indicator lamps located on the unit control panel: Spa and Poolthermostats Indicator lamps • Power (red lamp): When lit, indicates power is applied to the unit. NOTE: The heat pump will not run when the Remote position is selected and there is no remote control system attached. • Heat Demand (green lamp): When lit, indicates the actual water temperature is below the target water temperature. • Water Pressure (orange lamp): When lit, indicates normal water flow. V. System Start-Up 1. Verify that the Power lamp is ON, the pool pump is running and water is circulating properly. 2. Verify that the control panel Spa-Remote-Pool switch is in the Remote (OFF) position; see the figure below. 3. Turn the selector switch to Pool to turn the unit ON and raise the thermostat setting above the current water temperature. At this time all three lamps should illuminate and the fan should start to run. Control panel When all 3 lamps are lit, operation is normal. 4 NOTE: The heat pump will be OFF when the Remote position is selected on the Pool/Spa selector switch and there is no remote control system attached. Spa thermostat 4. Allow the heat pump to operate for a few minutes to Pool/Spa selector stabilize operating pressures and to allow various switch component temperatures to normalize. Pool thermostat5. Verify that the discharge air temperature is approximately 8° - 10° cooler than the air entering the unit. If not, see Section IX, Troubleshooting. Seasonal Start-Up or Annual Check NOTE: At the beginning of the heating season, or whenever the pool water temperature is to be raised several degrees, the pool pump and heat pump may need to operate continuously for several days. During summer months, only a few hours per day may be necessary, or none at all. 1. Remove leaves, pine needles, etc. from the evaporator coil. Clean the coil by gently applying a mild solution of household liquid soap and water. 2. Gently rinse the coil with water; do NOT use high pressure. 3. Backwash or otherwise clean the pool filter. If necessary, clean the skimmer basket and pump strainer. 4. Set the valves to assure proper water flow through the unit. NOTE: If the pool pump and heat pump shut OFF before the water temperature is raised to the desired level, you must lengthen the running time of both. To do this, reset the time clock dial for the longer running time, or manually operate the pump with the timer override switch. Since the heat pump capacity and efficiency are both greater at higher ambient air temperatures, run time should be set to take advantage of all daylight hours, when the air is generally warmer. VI. Summer Shutdown If you do not plan to use the heat pump during the summer months, secure and protect it as follows: 1. From the control panel, turn the control switch to Remote (OFF). 2. Turn the heat pump circuit breaker or disconnect switch to OFF. 3. Leave the valves set the way they are unless additional circulation is required. DO NOT stop all flow through the heat pump. 4. IMPORTANT: Remember to reset the valves before the next heating season, or the heat pump will not operate properly. 5 VII. Freeze Protection If the heat pump 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 heat pump circuit breaker or disconnect switch to OFF. 2. From the control panel, turn the control switch to Remote (OFF). 3. 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 Shop Vac or air pressure to remove excess water. 4. Re-attach the unions. 5. Cover the heat pump with a waterproof cover. Continuous Pump Operation It is also possible in some areas to prevent heat pump freeze damage by operating the pump continuously during freezing weather. However, this results in significantly higher pump operating cost. Further, if a sustained power failure occurs, the heat pump MUST be drained anyway, or freeze damage could result. VIII. Maintenance NOTE: The heat pump MANUFACTURER IS NOT RESPONSIBLE for maintenance adjustments. The following maintenance procedures are designed to keep your heat pump 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. A. Air Coil Cleaning - Ef...
