14.4.5 To charge refrigerant
Follow the steps as described below and take into account whether
you want to use the automatic charge function or not.
Pre-charging refrigerant
1 Calculate the additional amount of refrigerant to be added using
the formula mentioned in "14.4.3 To determine the additional
refrigerant amount"[423].
2 The first 10 kg of additional refrigerant can be pre-charged
without outdoor unit operation.
If Then
The additional refrigerant amount
is smaller than 10kg
Perform steps 3~4.
The additional refrigerant charge
is larger than 10 kg
Perform steps 3~6.
3 Pre-charging can be done without compressor operation, by
connecting the refrigerant bottle to the service ports of the liquid
and equalising stop valves (open valve B). Make sure that valve
A and all outdoor unit stop valves are closed.
NOTICE
During pre-charging, the refrigerant is charged through the
liquid line. Close valve A and disconnect the manifold from
the gas line. The equalising line is ONLY charged to break
the vacuum. Charge it to maximally 0.05 MPa (0.5 bar),
then close valve C and disconnect its connection to the
manifold. Continue pre-charging through the liquid line
only.
