on page 24 and solve the problem.
After correcting the problem, press
perform automatic refrigerant charging again starting from
step 4.2.
5 When charging is complete, determine the weight of refrigerant
that was added and fill in the amount in the "Additional
refrigerant charge label" attached to service precautions plate
on the unit.
6 After adding the refrigerant, do not forget to close the lid of the
service port. The tightening torque for the lid is 11.5~13.9 N•m.

"How to calculate
To avoid compressor breakdown. Do not charge the
refrigerant more than the specified amount.
If the total refrigerant cannot be charged while the
(*)
outdoor unit is at a standstill, it is possible to charge
the refrigerant by operating the outdoor unit using the
refrigerant charge function (refer to
on page
the outdoor unit is operating" on page
Procedure 3: Charging while the outdoor unit is operating
See the figure in
1 Close the front panel and turn on the power to all indoor units
and the outdoor unit.
2 Completely open the gas side stop valve and liquid side stop
valve. Valve A must be left fully closed.
3 Open valve A immediately after starting of the compressor.
4 Charge the additional refrigerant in its liquid state through the
service port of the liquid line stop valve.
5 While the unit is at a standstill and under setting mode 2 (refer to
"11.2. Checks before initial start-up" on page
mode" on page
refrigerant charging operation) to
starts. The blinking H2P led indicates test operation and the
remote controller indicates
(external control).
6 When the specified amount of refrigerant is charged, push the
BS3 RETURN
The operation automatically stops within 30 minutes.
4 If the refrigerant charge cannot be finished within 30 minutes,
repeat step 5.
2
If the operation stops immediately after restart, there is a
possibility that the system is overcharged.
3
The refrigerant cannot be charged more than this amount.
7 After the refrigerant charge hose is removed, make sure to close
valve A.
