The unit must be operated in cooling mode to nd out, if the
unit charge is correct, by checking the actual subcooling.
Following a small refrigerant leak a loss of refrigerant,
compared to the initial charge will be noticeable in the
cooling mode and affect the subcooling value obtained at
the air heat exchanger (condenser) outlet, but it will not be
noticeable in the heating mode.
IMPORTANT: It is therefore not possible to optimise the
refrigerant charge in the heating mode after a leak. The unit
must be operated in the cooling mode to check, if an
additional charge is required.

Aquasnap units use high-pressure R-410A refrigerant (the unit
operating pressure is above 40 bar, the pressure at 35°C air
temperature is 50% higher than for R-22). Special equipment
must be used when working on the refrigerant circuit
(pressure gauge, charge transfer, etc.).
