Carrier Aquasnap 30RQ User Manual

13.9 - Refrigerant volume
It is essential to run the unit in cooling mode to nd out whether
the charge is correct; this is done by checking the actual
subcooling.
Following a slight leak, it will be possible to detect a drop in the
refrigerant charge from the initial charge, and this will a󰀨ect the
subcooling value obtained at the air-cooled exchanger outlet;
it cannot, however, be detected in heating mode.
IMPORTANT:
It is therefore not possible to optimise the charge in heating
mode following a leak. The unit must be run in cooling mode
if the charge needs topping up.
