Troubleshooting: Fan blades turn but compressor is not functioning If you have an Insta Manual 2001, follow the steps in the next page. Preliminary Troubleshooting steps End user The pool heat pump has a built in time delay which prevents the compressor from starting immediately. In that case, the compressor will start in 3 to 5 minutes. If the unit is in defrost mode, the compressor will start between 3 to 20 minutes. It can sometimes be difficult to make the difference between the noise coming from the compressor and the noise coming from the fan motor. To avoid unnecessary service call fees, follow the steps below: 1. Check if the air being discharged from the fan blades is colder than the ambient air. If the air being discharged by the fan blades is colder, it means the compressor is functioning correctly; 2. Turn off the pool heat pump then immediately turn it back on; 3. As soon as the fan blades start turning, wait a minimum of 3 5 minutes. The compressor should start up after this time and you will be able to identify a different sound made by the compressor when it starts; 4. If the compressor is functioning but shuts off immediately, consult the troubleshooting: Compressor starts and stops. ***If the problem persists, call customer service department. Page 9 / 35
