FC Series Troubleshooting
High refrigerant pressure error
This issue is usually caused by insufficient water circulation. To resolve it:
Ensure the skimmer is clear of obstructions.
Check that the circulation pump basket is unobstructed.
Make sure the backwash has been completed.
Confirm that the bypass valve is closed and the inlet and outlet valves are open.
Verify that the circulation pump is functioning normally.
If the problem persists, please contact us.
If there are three high-pressure readings within the last hour, reset the circuit breaker or hold the Power button for 5 seconds.
Low refrigerant pressure error
This error is usually caused by a leak, but a few checks are important:
Ensure the fan is running.
Verify that the evaporator is unobstructed.
If the error code appears 3 times within the same hour, please contact us and follow these precautions:
Turn off the circulation pump.
Open the bypass valve.
Close the water inlet and outlet valves.
Restart the circulation pump. If your circulation pump is controlled by the heat pump, it will shut down automatically.
After completing these steps, reset the circuit breaker or hold the Power button for 5 seconds.
Insufficient water flow
This error typically indicates that no water is circulating inside the heat pump.
Please check the following:
Ensure that the circulation pump is running.
Verify that there are no obstructions in the water filtration system (skimmer, pump, or filter).
Confirm that the bypass valves are allowing water to circulate through the heat pump.
If the problem persists, please contact us.

A faulty defrost temperature sensor indicates it may be short-circuited or defective. Please check the sensor connection. If the issue persists, contact us.
Water error Delta temperature
This anomaly is typically due to insufficient water circulation.
Ensure the skimmer is clear of obstructions.

Ensure the bypass valve is closed and the water inlet and outlet valves are open.
Check that the circulation pump is operating normally.
Backwash reminder
Note that you will receive a weekly reminder to perform the backwash.
Evaporator wash reminder
Note that every 60 days, you will receive a reminder to clean your evaporator.

FAQ
Little or no water flow from pool heat pump
The pool heat pump requires a minimum water flow to function properly. Low or nonexistent water flow can cause the heat pump to malfunction. Some heat pump models will display an error code when water circulation is insufficient.
Power supply failure
Issues with your pool’s heat pump may be caused by power or current problems. The power supply to the heat pump can be interrupted in cases such as: poor connections or faulty wiring, which may cause the circuit breaker to trip.
Heat pump incompatibility with your pool's water capacity
If your heat pump is operating but fails to heat your pool water adequately, it may be a sizing issue. This means the heat pump may not be suited to the volume of water to be heated. Consult your supplier to confirm if your heat pump is appropriate for your pool size.
Obstruction or blockage of evaporator coil
Keeping the evaporator coil clear is essential for proper air circulation in your pool heat pump. If the coil is clogged or blocked, the heat pump won’t be able to heat your pool efficiently. Make sure to clean the coil thoroughly to maintain adequate airflow.
Ambient temperature too low
Heat pumps require a temperature above 4°C (39°F) to operate correctly. If the temperature drops too low, your heat pump may be unable to heat the water adequately, or at all.
Refrigerant pressure problem
The refrigerant in the heat pump plays a crucial role in heat production when compressed by the compressor. If the pressure is too low or too high, the heat pump may not heat properly:
Low pressure generally indicates that the temperature is too low for the heat pump to operate efficiently and produce heat.
High pressure often signals a water flow issue, meaning insufficient water is circulating to transport heat effectively.
Incorrect thermostat setting
If the heat pump isn’t running, it may be due to a lack of heating demand on the controller. Ensure the temperature is set higher than the current pool water temperature. If this doesn’t resolve the issue, check if there is an active timer or a minimum outdoor temperature setting that may be preventing the heat pump from operating outside the selected temperature range.
Running time at the start of the season
When the heat pump is first started up, it may take 1 or 2 days to reach the desired temperature.
How to Winterize a Nirvana Pool Heat Pump?
Winterizing Your Nirvana Heat Pump:
Turn off the circuit breaker.
Drain water from the heat pump and unscrew all water inlet and outlet connections.
Tilt the heat pump slightly backward to fully empty any remaining water.
Cover the water inlet and outlet with cloth or plastic to prevent rodents from entering the unit.
Is it necessary to put a winter cover on my pool heat pump? And where can I get one?
We recommend using a winter cover for your heat pump to provide extra protection for your unit.
You can purchase one at your usual retailer. Be sure to have your model number on hand to select the correct size cover.
How many degrees should the water temperature increase in 1 hour with a Nirvana pool heat pump?
The heat pump typically increases the water temperature by 1 degree per hour. However, ambient temperature and weather conditions may have a slight impact on this rate.
Once the desired temperature is reached, the heat pump will maintain a stable temperature continuously. To further reduce heating costs, we recommend using a liquid solar blanket.
Is it necessary to install a "by-pass"?
Nirvana pool heat pumps do not require a bypass to function properly. However, we highly recommend this option, as a bypass can be extremely useful if you ever need to divert water away from your heat pump.
Can I use a salt system with a Nirvana pool heat pump?
Absolutely! A salt system is fully compatible with a Nirvana heat pump.
Is the warranty of the Nirvana pool heat pump transferable if the house is sold?
Yes, the warranty is transferable. However, a technician must inspect the unit’s condition. The transfer fee is $125, with an additional $100 for the service call.
For a heat pump that has been sold and moved from its original location, the transfer fee is $225, plus a $100 service call.
How to differentiate water condensation from a water leak?
If you suspect a water leak in your Nirvana pool heat pump, here’s an easy way to check:
Allow water to circulate through the unit, but turn off the heating.
If the water stops running, it’s likely condensation. Depending on humidity levels, the heat pump can release up to 1.5 L of water per hour.
