Disconnect the charging hose, which is connected to the refrigerant cylinder, from the refrigerant charge port (only for automatic charging), and
connect the charging hose to the check joint on the low-pressure side.
If the length or diameter of the refrigerant pipe is unknown, add 1.5 kg of refrigerant for each outdoor unit.
* There is no need to adjust the refrigerant charge after the completion of the refrigerant oil recovery operation if the units are operated in the
cooling mode.
* If the total amount of refrigerant to be charged during refrigerant oil recovery operation exceeds the maximum amount in the table below, refrig-
erant does not need to be added.
* If a built-in pressure gauge is connected to the check joint on the low-pressure side, use the check joint on the liquid valve in the heating mode,
and the check joint on the gas valve in the cooling mode.
7Check for successful completion of the refrigerant oil recovery operation.
Procedure 8
Turn the dipswitches 1-4, 1-5, 1-6, and 1-7 to ON to verify that the refrigerant oil recovery operation is completed. "S-1" or "r-1" on
the outdoor unit's LED indicates a successful completion.
* When multiple outdoor units are connected in a system, refer to the followings for which dipswitch should be operated.
• When different capacity outdoor units are combined, operate the dipswitch on the larger capacity unit.
• When the same capacity outdoor units are combined, operate the dipswitch on the unit whose address is smaller.
"S-1" "r-1": The refrigerant oil recovery operation is successfully completed. Go to the next procedure.
"S-1" "r-0": The refrigerant charge adjustment is not completed, but regular air conditioning operation can be started. If there was excess
refrigerant that had not been charged, charge it through the low-pressure check joint (CJ2) during the air conditioning operation.
"S-0" "r-1": The refrigerant oil recovery operation is not completed. To restart the refrigerant oil recovery operation, set the dipswitches 3-1 and
4-8 to ON in that order.
"S-0" "r-0": The refrigerant oil recovery operation is not completed. To restart the refrigerant oil recovery operation, set the dipswitches 3-1 and
4-8 to ON in that order.
