6.7.5 To charge refrigerant
Follow the steps as described below.
Pre-charging refrigerant
1 Calculate the additional amount of refrigerant to be added using
the formula mentioned in "6.7.3 To determine the additional
refrigerant amount"on page23.
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 2+3.
The additional refrigerant charge
is larger than 10 kg
Perform steps 2~8.
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.
