Page 15 of 22 HEATPRO HEAT PUMP HP13023772 Rev: D Some heat pump owners desire their pool to be heated during the winter months. This is possible when daytime temperatures are above 50°F [10°C] for most of Hayward's heat pumps. If temperatures fall below freezing, be certain to keep the pool filter pump operating continuously to prevent freeze damage. WARNING - While the plumbing connections are in the winterized condition (disconnected from heat pump), it is imperative that the pool / spa water is NOT circulated through the heat pump. Loss of water through loose plumbing connections may result in damage to circulating pump, pool / spa structure and / or other equipment. Performance Maintenance and Troubleshooting Service Procedures Before Calling For Service If there appears to be a problem, refer to the troubleshooting section on the following pages. 1. Ensure the swimming pool filtration system is turned on. 2. Ensure the main power circuit on. 3. Verify that the heat pump is not in stand-by mode (pool or spa indicator light is illuminated). 4. Ensure that the heat pump thermostat is set at a temperature above that of the pool or spa temperature. 5. Ensure the outside temperature is high enough to allow the unit to operate. Hayward heat pumps will not turn on when the outside air temperatures near 50°F (10°C).
