NOTE: The heat pump will be OFF when the Remote position is selected on the Pool/Spa selector switch.

4.Allow the heat pump to operate for a few minutes to stabilize operating pressures and to allow various component temperatures to normalize.

5.Verify that the discharge air temperature is approximately 4°C - 6°C cooler than the air entering the unit.

VI. Seasonal Start-Up or Annual Check

1.Remove leaves, pine needles, etc. from the evaporator coil. Clean the coil by spraying it with a mild solution of household liquid soap and water.

2.Flush the coil with a garden hose; DO NOT use a high-pressure sprayer.

3.Backwash or otherwise clean the pool filter. If necessary, clean the skimmer basket and pump strainer.

4.Set the valves to assure proper water flow through the unit.

5.Set the water temperature control to the desired temperature range for either pool or spa.

6.Turn the control switch to either Pool or Spa. If the pool pump is running and the water is colder than the setting of the temperature control, the heat pump will start up and run. It will run until the desired water temperature is reached, or until the pool pump shuts OFF.

NOTE: If the pool pump and heat pump shut OFF before the water temperature is raised to the desired level, you must lengthen the running time of both. To do this, reset the time clock dial for the longer running time, or manually operate the pump with the timer override switch. Since the pool heat pump capacity and efficiency are both greater at higher ambient air temperatures, run time should be set to take advantage of all daylight hours, when the air is generally warmer.

VII. Heat Pump Running Time

1.Determine the length of pump and heat pump operating time necessary for your particular requirements. Minimum run time should be the required hours to attain proper pool water filtration. Maximum run time obviously is 24 hours per day, or as required to reach desired pool temperature, and depends on such things as weather, pool size, covering, shading, etc.

2.If cooler or warmer water is desired, simply adjust the water temperature control and/or the pump and heat pump operating time accordingly, until the desired water temperature is reached.

NOTE: At the beginning of the heating season, or whenever the pool water temperature is to be raised several degrees, the pool pump and heat pump may need to operate continuously for several days. During summer months, only a few hours per day may be necessary, or none at all.
