• 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 chemistry test kit to confirm there is no chlorine in the condensation. Or, b. Shut the unit OFF and leave the filter pump running to see if the water stops dripping. If the water stops dripping, the unit is not leaking. 14 Service Call Verification Before you make a service call, first determine if the problem is: • Warranty Service • Unit operation (power supply, water flow, or time clock adjustment) NOTE: The MANUFACTURER IS NOT RESPONSIBLE for these adjustments. Power Supply • Verify that all circuit breakers are reset and working properly. • If the temperature display or the Power lamp on the control panel still does not light, contact the installing dealer, since it may be a power problem requiring an electrician. 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. • If the Water Flow lamp (analog models) on the control panel still does not light, and water is circulating in the pool, verify that all valves are positioned correctly. 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 and shuts down the unit and pool pump for protection. If this occurs, you should call for service. HP & HP3 Low water flow in the unit or faulty high pressure control. Check water flow/backwash. The unit will show (HP3) after 3 HP faults. This will stop the unit for protection. FLo & FL3 Possible causes: • The filter is in backwash position. • The filter pump is stopped. • The filter is dirty. • Shortage of water to pool pump. • FIL parameter must be set to activate pool pump. • Water pressure switch must be adjusted or it is broken. • The unit is in the protection mode and will show (FL3), press any key to restart the unit. FL3 code will stop the unit and pool pump. FS Unit is in the defrosting cycle. (The fan works but the compressor is stopped.) - Keypad is pressing down on both buttons. Replace keypad.

Connections are 2-inch unions. Plumb the heat pump pool heater AFTER the filter and BEFORE any chlorinators. Water In (from pool or spa) Water Out (to pool or spa) Filter Fig. 7: For systems with pumps of 2 HP or greater (over 80 gpm), an external bypass is required. Adjust the bypass valve to divert a minimum of 40 gpm through the heat pump pool heater. Connections are 2-inch unions. Plumb the heat pump pool heater AFTER the filter and BEFORE any chlorinators. 17 UNITS UNITS UNITS Fig. 8: Pool Piping for Heat Pump Pool Heater and Gas Pool Heater Fig. 9: Pool Piping for Heat Pump Pool Heaters, Multiple, Primary/Secondary Wiring Diagram — 208V/230V Single-Phase — Analog Models USE COPPER CONDUCTORS ONLY USE 75 ° C 600 V WIRE TORQUE SCREWS : 40 LB -IN FACTORY STANDARD FIELD INSTALLED LINE VOLTAGE LOW VOLTAGE FACTORY STANDARD FACTORY OPTION WIRING INFORMATION USE TERMINALS 21 & 22 TO ATTACH 2 WIRE CONTROL SYSTEMS THAT HAVE THIER OWN SENSORS FOR TEMPERATURE CONTROL.
