Troubleshooting Check the installation of the heat pump first to assure it is installed per the installation manual. Ensure the electrical hook-up is correct by checking the breaker is sized correctly for your unit and the wiring is per the National Electric Code. Reference the installation manual to ensure that the plumbing is installed correctly. Circuit Breakers: if you suspect that a circuit breaker may be tripped, turn the breaker to the "off" position and then back to "on". Visually checking the breaker is "on" is inadequate, as some switches move only a short distance when they trip. Toggle the switch to "off" then "on" every time you suspect it is tripped. Troubleshooting a Chiller model or cooling cycles of a heat/cool unit: If you are troubleshooting problems with a Chiller model or cooling cycles of a heat/cool unit, the following charts cover the majority of issues. If you are unable to resolve or determine a problem, additional info can be obtained by contacting the HAYWARD Service Dept. Troubleshooting Guide for MECHANICAL Thermostat Control Problem Possible Cause Possible Solution(s) Heat pump is not running (Note: the pool filter pump must be running before the heat pump will operate.) No power to unit Breaker is thrown Thermostat not turned up high enough 5 minute delay timer still running Low water flow Make sure power is on. Check the breaker / see note above Turn thermostat up until unit comes on Be sure the 5 minute delay has passed Make sure filter is clean Make sure filter pump is on Unhook cleaning devices (skimmers, crawlers, etc.) Outside temperature to low Check outside ambient temperature / wait for warmer temperatures for unit to operate. (refer to Operating Principles) Heat pump running but not heating "Heat" or "RUN" does not come on. Fan not functioning Make sure thermostat is high enough System Component failure. Call HAYWARD for service info. Adjust thermostat for higher heating temperatures. Refer to page 7 to find your thermostat instructions. Call HAYWARD for service info. Heat pump runs continually Thermostat set too high Electrical component failure Turn thermostat down Turn off the filter pump. If the unit is still running after 2 minutes, turn off the power to the unit and contact HAYWARD for service. Heat pump is cycling (on / off too quickly) Bad valve or improper water flow Low refrigerant, low ambient temp, or high humidity with low ambient temp Check valve settings and ensure water flow is sufficient (is the filter pump running continually?) If heat pump continues to cycle, turn unit off to prevent compressor damage. Check evaporator coil for severe frost. Turn unit off to prevent compressor damage. If heat pump continues to cycle, turn unit off to prevent compressor damage. Water coming from bottom of unit Condensation Possible water leak This is normal and there is no reason to be concerned Turn the unit off for at least 2 hours, but leave the filter pump running continuously. If water dries up then it is only condensation. Otherwise there is a possible leak. 16
