Test Operation
81
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 “Setting mode 2” on page 108) and follow "Procedure 3: Charging while the outdoor
unit is operating" on page 81.
See the figure in "How to connect the tank?" on page 77.
1. Completely open the gas side stop valve and liquid side stop valve. Valve A must be left fully
closed.
2. Close the front panel and turn on the power to all indoor units and the outdoor unit.
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 Checks before initial start-
up, "Setting mode 2" on page 108), set the required function A (additional refrigerant
charging operation) to ON (ON). Then operation starts. The blinking H2P led indicates test
operation and the remote controller indicates TEST (test operation) and
(external
control).
6. When the specified amount of refrigerant is charged, push the BS3 RETURN button. Then
operation stops.
The operation automatically stops within 30 minutes.
If the refrigerant charge cannot be finished within 30 minutes, repeat step 5.
If the operation stops immediately after restart, there is a possibility that the system is
overcharged.
The refrigerant cannot be charged more than this amount.
7. After the refrigerant charge hose is removed, make sure to close valve A.
