Open both the high-pressure and low-pressure valves.
Use a hexagonal wrench to open the valves. Refer to the table below for the proper wrench size.
4Connecting the refrigerant cylinder(s)
Procedure 4 If the required amount of refrigerant is not charged, disconnect the charging hose connected to the refrigerant cylinder from the
service port on high-pressure and low-pressure side, and connect the charging hose to the refrigerant charge port CJ3
(only for automatic charging).
* Check that each cylinder has the correct amount of refrigerant.
* If the amount of refrigerant is insufficient, the units may stop during refrigerant oil recovery or it may take longer than usual to complete a test
run.
5Setting the unit address and checking for proper system operation
Procedure 5
Set the unit address, turn on the power, and check for proper operation of the system.
* If an attempt is made to operate the outdoor unit before the refrigerant oil recovery operation is complete, an error code 7116 will appear on the
remote controller. This does not indicate a malfunction. Wait for the oil recovery operation to be completed. The error code 7116 will go off upon
completion of oil recovery operation.
