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 heat the pool with greater economy than other types of fossil fuel heaters. Place a cover or blanket over the pool at night and other non-use periods. This will keep evaporation, the cause of main heat loss, to a minimum, and will greatly reduce pool heating costs. During warmer weather, the cover may be required only at night. 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). • You must install the 4 black rubber sound isolation pads (each 2 inches square) that ship with the unit. The pads are shipped in a bag with the unions, gaskets and the I&O manual. Install pads under the 4 corners of the unit to reduce vibration and sound transmission to the base. CAUTION: The unit’s supporting base must be high enough to keep it completely free of standing water at all times. Situate the heat pump pool heater carefully to minimize installation costs while providing maximum efficiency of operation, and to allow adequate service access, as follows: • For unrestricted air intake and service access, position each side of the unit at least 1 ft (30 cm) from walls, pipes and other obstructions. WARNING: This unit is designed for outdoor installation; DO NOT install it in an enclosed area such as a shed or garage. • Recirculation of cold discharge air back into the evaporator coil will greatly reduce the unit’s heating capacity and efficiency. • This unit features an ‘up-flow’ discharge for quiet operation. Air is pulled up through the evaporator coil and discharged through the top grill. Allow at least 5 ft (1.5 m) clearance above the unit for unrestricted air discharge. DO NOT install the unit under a porch or deck. Refer to Fig. 1. • To minimize water piping, locate the unit as close as possible to the existing pool pump and filter. 5 GAS HEATER AIR FLOW IN AIR FLOW IN AIR FLOW OUT3 FT (90cm) MIN 12” (30cm) MIN 60” (1.5m) MIN 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. • Locate the equipment disconnect means within 3 feet (90cm) of the heater’s electrical enclosure, or as close to the heater as possible. Always satisfy applicable codes and standards. • In sizing power wiring, be especially aware of up- sizing requirements ...
