The unit’s supporting base must be high enough to keep unit completely
free of standing water at all times.
Situate the pool heat pump carefully to minimize installation costs while providing maximum
efficiency of operation, and to allow adequate service access, as follows:
Air flow path: For unrestricted air intake, position the unit at least 1 ft from walls, pipes and
other obstructions, but allow 2 ft access to the service panel.
The unit is designed for outdoor installation; do NOT install it in an enclosed area such as a
shed or garage, unless ventilation is provided to ensure adequate air exchange for proper
operation. Recirculation of cold discharge air back into the evaporator coil will greatly
reduce the unit’s heating capacity and efficiency.
This unit feature an ‘up-flow’ discharge for quiet operation. Air is pulled up through the
evaporator coil and discharged through the top grill. Allow at least 8 ft clearance above the
unit for unrestricted air discharge. Do NOT install the unit under a porch or deck.
To minimize water piping, locate the unit as close as possible to the existing pool pump and
filter.
When installed in areas where freezing temperatures can be encountered, drain the water
circuit to prevent possible freeze-up damage. See Section IX, Freeze Protection.
II. Electrical Connections
Refer to the unit rating plate below the control panel for precise power requirement for your unit,
and for ampacity and over-current protection requirements.
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 for installation
information.
III.Water Connections
The heat pump inlet and outlet connections are NOT interchangeable.
They must be connected as instructed below.
1. Connect the heat pump in the return water line between the filter and the pool/spa. See Plumbing
Diagrams.
2. Connect the filter outlet to the fitting marked WATER IN at the bottom front of the unit.
3.Connect the fitting marked WATER OUT to the return piping to the pool/spa. Unit inlet/outlet
connection fittings are PVC unions. Water connections from the heat pump to the main return
line can be PVC pipe or flexible pipe approved for the purpose and, in either case, should be at
least equal in size to the main pool/spa circulation piping.
4. In cold weather (freeze zone) areas, shutoff valves (ball or gate type) must be installed at the
heat pump inlet and outlet to facilitate service and cold weather drain-down.
5. Operate the pump and check the system for leaks.
