To Increase the Desired Water Temperature (Pool or Spa Mode) Push the SET key until you see POL or SPA. The programmed temperature will be displayed. Press the UP arrow to increase the temperature setting one degree at a time. To Lower the Desired Water Temperature (Pool or Spa Mode) Push the SET key until you see POL or SPA. The programmed temperature will be displayed. Press the DOWN arrow to decrease the temperature setting one degree at a time. Once the control has been programmed to the desired pool water temperature, the programmed temperature will be displayed for approximately 5 seconds. Then the digital display will display the actual pool water temperature. To Select Temperature in °C or °F Press the SET key until you see F _C. By pressing the UP or DOWN key you can switch to °F or °C. Once the temperature display mode has been programmed it will be displayed for approximately 5 seconds, then the digital display will return to the actual pool water temperature in the mode that you have chosen. System Start-Up 1. Verify that the Digital Board is displaying a temperature and the pool pump is running and water is circulating properly. 2. Verify that the Board is programmed so that the desired temperature of the Pool and Spa is higher than the displayed current water temperature. 3. Allow the heat pump pool heater to operate for a few minutes to stabilize operating pressures and to allow various component temperatures to normalize. 4. Verify that the discharge air temperature is approximately 8°–10°F cooler than the air entering the unit. If not, see the Troubleshooting Section. Seasonal Start-Up or Annual Check 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 pool heater may need to operate continuously for several days. During summer months, only a few hours per day may be necessary, or none at all. 1. Remove leaves, pine needles, etc., from the evaporator coil. Clean the coil by gently applying a mild solution of household liquid soap and water. 2. Gently rinse the coil with water; DO NOT use high pressure. 3. Backwash or otherwise clean the pool filter. If necessary, clean the skimmer basket and pump strainer. 8 NOTE: If the pool pump and heat pump pool heater 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 heat pump pool heater 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. 4. Set the valves to ensure proper water flow through the unit. Summer Shutdown If you do not plan to use the heat pump pool heater during the summer months, secure and protect it as follows: 1. Turn the unit circuit breaker or disconnect switch to OFF. 2. Leave the valves set the way they are unless additional circulation is required. DO NOT stop all flow through the heat pump pool heater. 3. IMPORTANT: Remember to reset the valves before the next heating season, or the unit will not operate properly. Freeze Protection If the unit is installed in a location subject to freezing c...
