RESOLUTION
If the heat pump is a reversing unit, place it in heating mode and perform the following
troubleshooting.
Determine if an insufficient amount of water is being supplied to the equipment.
1. Confirm the filter pump is on.
2. If a multiple-speed filter pump is being used, run filter pump at a higher speed. Do not exceed the
maximum flow rate for the model.
3. Confirm water is not being diverted away from the heat pump.
