High voltage. Danger! Use
extreme caution. Do not
attempt if you are not a
qualified servicer.
Warning!
The following heat pump Troubleshooting Guide is to be used in diagnosing and repairing Hayward &
Summit branded pool heat pump systems containing R-410A refrigerant . They are not intended for use
with any other manufacturers heat pumps.
Heat Pump pool heaters are similar to the heat pumps for home heating and cooling in that they contain
refrigerant. As such, service personnel should observe EPA regulations for refrigerant handling. Pool heat pumps
operate on 240 volts A/C. There is a risk of electric shock at all terminals and the heat pump should only be
serviced by trained personnel.
To use this guide, determine the model number of the heat pump and the nature of the problem. Refer to
the Table of Contents to find the appropriate page for the problem and follow the flow charts to the solution.
