Heat Pump Pool / Spa Heater Owner's Manual Service Procedures Before You Call For Service If there appears to be a problem, refer to the troubleshooting guide on the following pages. There is an additional troubleshooting chart available at the end of the installation manual containing information for troubleshooting your heat pump. 1. Make sure that the swimming pool filtration system is turned on. 2. Is the main power (circuit breaker) on? 3. Is the "Power" indicator light illuminated? 4. Is the heat pump thermostat set at a high enough level to enable the system to turn on? Adjust the thermostat to a higher setting. 5. Check the outside temperature. HAYWARD heat pumps will not turn on when the outside air temperatures drop near 45 degrees. 6. Make sure that the pump and skimmer baskets are free of debris. Also ensure that the pool filter is clean and supplying proper water flow to the heat pump. 7. The heat pump is not able to maintain your desired temperature? Depending on the time of the year, you may need to adjust your pool filtration systems hours of operation (increase run time). Note: Use a solar blanket/cover on the surface in order to keep a higher level of heat retention. Heat Pumps with Electronic Displays 1. If diagnostic code "PS" is illuminated, this indicates improper water flow. Ensure that pool filter pump basket, skimmer basket, and filter are free of debris and clean. 2. If diagnostic code "LP" is illuminated, this indicates that the outside air temperature is too low. When this occurs the Heat Pump shuts itself off automatically. When the outside air temperature rises enough the heat pump will automatically turn on. 3. If diagnostic code "HP" is illuminated, this indicates that a low water flow condition may exist. Check to see that the pool pump basket, skimmer basket and pool filter is clean. After checking these items, if the "HP" indicator is still illuminated contact HAYWARD for service. 15
