Heat Pump Is Running, Not Cooling
ISSUE
The heat pump is running. But the water is not cooling.
RESOLUTION
1. If the heat pump is using an external controller, confirm the heat pump is programmed properly to
allow for cooling.
l
See " Operating Heat Pump (With an External Controller) " on page 20.
2. Confirm the heat pump mode is set to cool.
3. Confirm the thermostat is set below the current water temperature.
4. Confirm valves are positioned to cool the correct body of water (either the pool or the spa). If cooling a
spa that overflows into a pool, confirm the spa is isolated when being cooled (not flowing into the
pool).
5. If an error code is displayed, determine and correct the condition causing the code.
l
See " Fault Codes " on page 35.
6. Confirm heat pump is transferring heat out of the water.
l
Measure the temperature of air discharge coming out of the heat pump's fan. If the air is between 8°
to 10° F (4.4° to 5.6° C) warmer than the outside ambient air, the heat pump is moving heat out of
the water.
7. Confirm that the filter pump has a sufficient run-time. The heat pump will not run (or cool the
water) without water flow.
