Quick Start & Stop

This brief information is provided as an aide to installers, service personnel, and owners. The intent of this section is to provide rapid access to (only) very basic operational information. Individuals who will be routinely using, installing, maintaining and servicing this heat pump are strongly encouraged to read this entire manual. If uncertain about any instructions given herein, AquaCal Customer Support (800-786-7751) should

be contacted for additional information.

Start Up

1.Set pump controls to allow for temporary, continuous operation.

2.With pump OFF, position water valves to heat the POOL or SPA.

3.Rotate both thermostats counterclockwise to lowest temperature setting.

4.Depending on valve settings (per #2, above), position the POOL/OFF/SPA toggle switch to point at either the POOL or SPA thermostat knob.

5.Ensure power is supplied to the heater, then start the water pump; the POWER and FLOW lights should now both be lit. Permit the water pump to operate for five (5) minutes before proceeding

How to Operate the Controls - Pool or Spa

1.Turn the selected pool or spa thermostat dial clockwise to its highest setting.

2.The heat pump will start and begin to heat the pool or spa.

NOTE: The heat pump has a time delay so if it shuts down for any reason, it will not restart for approximately five (5) minutes.

3.The typical spa may take several hours to initially heat up, while a pool may take several days. Heating time will depend on the volume of water, water temperature, and the climatic conditions at the time of start-up. (Also see Calculating Initial Heating Time.)

4.When the pool or spa reaches the desired temperature, slowly rotate the thermostat knob counterclockwise until the heat pump (just) stops. The thermostat is now set to automatically maintain this temperature.

Time Clock Programming

Once the heat pump has brought the pool or spa up to temperature, it will be necessary to reset the pump controls. Be sure to allow enough running time for the heat pump to replace lost heat. This time will vary depending upon the time of year. Colder months require longer running times—usually eight to twelve hours.

Manual Switching From Pool to Spa

NOTE: It is best to stop the pump while repositioning valves.

1.Open spa valves and close pool valves.

2.With the spa filter pump running for at least five minutes, move the POOL/OFF/SPA toggle switch from the Pool Setting to the Spa Setting.

3.Turn the Spa thermostat clockwise until it stops (104 F).

4.The typical spa may take several hours to initially heat up. Heating time all depends on the volume of water, water temperature and the climatic conditions at the time of start-up.

5.When the spa reaches the desired temperature (104 F is maximum), slowly rotate the thermostat knob counterclockwise until the heat pump (just) stops. The spa thermostat is now set to automatically maintain this temperature any time the spa thermostat has been selected.

To Stop the Heat Pump

The unit can be stopped by switching off the electrical supply or by setting the desired temperature lower than the actual water temperature.
