HEATING-QUICK START & STOP (continued):

3.To Begin Heating:

A.Verify MODE is set to: HEAT (HEA); then, depending on which body of water is to be heated, use the POOL / SPA selector key to select POOL or SPA.

B.Position external water valves appropriately to flow water to & from the body of water and through the heater.

C.Start the water pump; the fan will start, and within 4-minutes (depending on the status of the controller’s internal time delay) the unit will begin heating. The selected body of water will be brought to temperature and maintained per the setting determined previously in: “Set the Heater Controls.”

D.In operation, whenever the actual (displayed) water temperature falls below the desired set point, after an initial time delay of 4-minutes, the unit will begin heating.

NOTE: THE HEATER CONTROLLER INCORPORATES AN ANTI-SHORT CYCLE TIME DELAY. SHOULD OPERATION BE INTERRUPTED, RESTART WILL BE DELAYED BY APPROXIMATELY 4-MINUTES.

4.Program Filter Pump Run Time:

Most pool/spa systems utilize a timer or multifunction controller to manage filter pump run times. If your system incorporates such a device, follow the instructions below:

A.It will be necessary to allow the filter pump to run continuously until the water has reached the desired temperature. If a timer controls the pool filter pump, it will be necessary to override the timer to allow 24-hr. operation.

B.Once the desired temperature has been obtained (1-4 days), reset the pump control device. Colder months require longer running times–generally eight to twelve hours/day.

C.A heat pump can only operate when the filter pump is running. Therefore, it may be necessary–during cooler weather–to extend the water pump’s hours of daily operation. The increased run time is necessary in order to keep up with increased, weather-related heat losses.

5.Continuous Usage and Water Around Heater:

Condensation... After the heat pump has been operating for some time, water may be observed surrounding the heater. The moisture seen is condensation produced as a normal by-product of transferring heat from the air into the pool or spa water. Quantities of 6-8 gallons of water produced per hour are common if the air humidity is high. Conversely, a low humidity condition may result in no condensation being produced. (If water around unit seems excessive, to troubleshoot, see page-26, “Water Coming from the Heat Pump.”)

6.To Stop the Heat Pump:

A.Select: OFF via the MODE selector. This method of shut down preserves the controller settings;

B.An interruption of water flow–such as when a pump timer is in control–will also halt heat pump operation.
