POOL/OFF/SPA (P/O/S) Toggle Switch and Sequence of Operation

With the toggle switch in the OFF (O) position, the heater will be prevented from operating (however, there may be power to the unit; see "Power Light On", below). With the toggle switch positioned toward the SPA or POOL thermostat knob, with HEAT selected, and with the following conditions met: 1) water pump in operation, with water flowing through the heater, and, 2) electrical power to the heater, the heater will run if the water temperature drops below the thermostat setting. If COOL is selected, the heater will operate if the water temperature rises above the thermostat set point.

Note- In Heat Mode, Heater Can Start with Thermostats Set to Minimum:

With proper water flow and electrical power supplied to the heater, and either the POOL or SPAthermostat selected and set to minimum, the heater will operate if the water temperature falls below 60º F. Likewise, if mode is set to COOL, with thermostats set to maximum, and in the unlikely event the water temperature rises above 104º F, the heat pump will operate to cool the water to a point below 104º F. If heat pump operation is absolutely not desired, position the POOL/OFF/SPAtoggle switch to the middle, OFF position.

Power Light On

Indicates electrical power is supplied to the heater. The heat pump will start if the selected (POOL or SPA) thermostat calls for heating or cooling, and there is proper water flow through the heater.

Power Light Off

Indicates proper electrical power is not supplied to the heater. If attempting to operate the heater, ensure all heater-related disconnect switches and/or circuit breakers are switched to the ON position.

Flow Light On

Indicates sufficient water flow to permit the heater to operate. The heat pump will start upon a call for heating or cooling.

Initial Start-Up and Basic Operation

(Please refer to "Overview of Controls", above, before continuing.)

1.Set P/O/S Toggle Switch to OFF—Lower or Raise Thermostat Settings:

♦Position the POOL/OFF/SPA toggle switch to "OFF".

♦If preparing to HEAT, turn both thermostat knobs counterclockwise to lowest settings. If preparing to COOL, turn both thermostat knobs clockwise to highest settings.

2.Establish Water Flow and Electrical Power to the Heat Pump:

♦With circulator pump off, position the water valves to heat or cool either the pool or the spa. If system is equipped with an external pump/valve/heater controller, simply use controller to position valves to pool or spa setting, and to start the appropriate water pump.

♦Ensure any heat pump-related disconnect switches, or circuit breakers, are switched to the ON position.

♦If not already operating, start the pool or spa pump (depending of which body of water is to be heated or cooled), permitting the pump to operate for a few minutes before going on to next step. This wait is necessary to clear any air that may exist in the water piping.

♦The heat pump will not start without electrical power and water flowing through it. At this point, the power light and flow lights should be illuminated.
