Water Chemistry (Corrosive water voids all warranties) For your health and the protection of your pool equipment, it is essential that your water be chemically balanced. The following levels must be used as a guide for balanced water. Recommended Level(s) Fiberglass Pools Fiberglass Spas Other Pool & Spa Types Water Temp. (Deg. F) 68 to 88 89 to 104 68 to 104 pH 7.3 to 7.4 7.3 to 7.4 7.6 to 7.

Warnings — Pay Attention to These Terms DANGER: Indicates the presence of immediate hazards which will cause severe personal injury, death or substantial property damage if ignored. WARNING: Indicates the presence of hazards or unsafe practices which could cause severe personal injury, death or substantial property damage if ignored. CAUTION: Indicates the presence of hazards or unsafe practices which could cause minor personal injury or product or property damage if ignored.
Introduction Installation Considerations WARNING: Do not install the unit within 3 ft of fossil fuel burning heaters. Air intake along the sides of this heat pump pool heater could disturb the combustion process of the unit, and could cause damage or personal injury. • Mount the unit on a level, sturdy base, preferably a concrete slab or blocks. The size of the base should be at least 3 ft by 3 ft (90cm by 90 cm).
0” (1.5m) MIN 3 FT (90cm) MIN GAS HEATER AIR FLOW OUT 12” (30cm) MIN AIR FLOW IN AIR FLOW IN Fig. 1: Installation Clearances • When installed in areas where freezing temperatures can be encountered, drain the water circuit to prevent possible freeze-up damage. See the Freeze Protection Section. Electrical Connections Refer to the unit rating plate below the control panel for precise power requirements for your unit, and for ampacity and over-current protection requirements.
WATER IN WATER OUT Fig. 2: Water Connections Water Connections Controls CAUTION: The heat pump pool heater inlet and outlet connections are NOT interchangeable. They must be connected as instructed below. Your heat pump pool heater incorporates digital safety controls and indicators to ensure its safe, reliable operation. 1. Connect the heat pump pool heater in the return water line between the filter and the pool/spa. See the Plumbing Diagrams beginning on page 12.
To Select Temperature in °C or °F Defrost Sensor: Prevents unit operation if ambient air temperature falls below a predetermined safe minimum (approximately 42°–48°F, based on humidity). The compressor will shut OFF but the fan will continue to run. Press the SET key until you see F _C. By pressing the UP or DOWN key you can switch to °F or °C.
Continuous Pump Operation NOTE: If the pool pump and heat pump pool heater 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.
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.
Service Call Verification Water Flow Before you make a service call, first determine if the problem is: • Verify that the pool filter is clean to provide good flow. • Warranty Service • Verify that valves are properly positioned to allow adequate water flow through the unit. • Unit operation (power supply, water flow, or time clock adjustment) Time Clock Adjustment Verify that the time clock is set to permit the unit to run long enough to heat properly.
WATER IN (FROM POOL OR SPA) FILTER CHECK VALVE CHEMICAL INTRODUCTION WATER OUT (TO POOL OR SPA) Plumbing Diagrams Fig. 4: For systems with pumps of less than 2 HP (under 80 gpm), no external bypass is required. Connections are 2-inch unions. Plumb the heat pump pool heater AFTER the filter and BEFORE any chlorinators.
WATER OUT (TO POOL OR SPA) WATER IN (FROM POOL OR SPA) FILTER CHECK VALVE CHEMICAL INTRODUCTION Fig. 5: 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.

Installing a Remote Control Device Wiring For a 2-wire control, use the TOTAL and COMMON connections on the heat pump pool heater wiring block. For a 3-wire control, use the COMMON, SPA and POOL connections on the heat pump pool heater wiring block. Heater Settings 1. Make sure the heater is disabled on the remote control device. Then, push the SET key until POL is displayed. Push the DOWN arrow key until OFF is displayed. Wait until a temperature is displayed before beginning the next step. Fig.
