Water Flow • Verify that the pool filter is clean to provide good flow. • Verify that valves are properly positioned to allow adequate water flow through the unit. Time Clock Adjustment Verify that the time clock is set to permit the unit to run long enough to heat properly. Fault Code Meaning of Code OFF The desired programmed temperature point is lower than 60°F (15°C). LP ! LP3 Shortage of refrigerant gas in the unit or faulty low pressure control. The unit will show (LP3) after 3 LP faults a

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

Always satisfy applicable codes and standards. • In sizing power wiring, be especially aware of up- sizing requirements necessary due to wiring distances. Always satisfy applicable codes and standards. • Electrical installation should be done by a licensed electrician only. This unit is pre-wired to work with external control systems, heat-on-demand options and other external time clock overrides. Refer to the external control system’s instructions, and page 19 of this manual, for installation i

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 ind

As with all heat pump pool heaters, compared to other types of heaters such as gas or oil-fired, this heat pump pool heater has lower heating capacity on a BTUH/hr basis. As a result, it will be required to operate longer to accomplish the desired results. It may, at certain times, operate as much as 24 hours per day. However, this should not be of concern to the owner, because the unit is designed to operate continuously. Even though it may operate continuously for many hours, it will still hea

• Is the Heat Light or Heat Demand lamp ON? If not, then the thermostat setting is not higher than the temperature of the water. Raise the thermostat setting. NOTE: The heat pump pool heater will not run when the Remote position is selected on the Pool/Spa selector switch and there is no remote control system attached. C. CONDENSATION SEEMS EXCESSIVE Heat pump pool heaters can produce a large amount of condensation (water) during operation. If you suspect that the unit is leaking: a. Use a pool

Refrigerant Low Pressure Control: Stops the com- pressor if refrigerant suction (low side) pressure falls too low as a result of a malfunction, loss of charge or extreme cold conditions. Indicator Lamps: There are 6 indicator lamps located on the unit control panel (see Fig. 3 below): • Power (amber lamp): When lit, indicates power is applied to the unit. • Water Flow (green lamp): When lit, indicates nor- mal water flow. • Heat Demand (green lamp): When lit, indicates the actual water temperatu
