To ensure adequate presence of gas in your Nano heat pump, follow these simple steps:

Temperature Check

Start your heat pump and let it run in heat production mode for at least 15 minutes. Access your heat pump settings and note the following information:

A - Water inlet temperature
B - Evaporator temperature
C - Ambient air temperature

If temperature B and C are different, it indicates that gas is properly compressed in the heat pump.

Note: Only Nano Turbo heat pumps come with a pressure gauge.

Pressure Gauge Check (Only for Nano Turbo)

If your Nano Turbo heat pump is equipped with a pressure gauge, follow these additional steps:

1. Turn off your heat pump and let it completely defrost for at least 30 minutes.
2. Check the pressure gauge, which has two scales: one in PSI outward (not relevant for us) and one in degrees Celsius inward.

If the outside temperature is, for example, 20°C, the temperature displayed on the gauge should be similar within 2 or 3 degrees. This confirms a good level of gas in your heat pump.
