3. Open the valve B ( See the figure 30 . The valve A,C and the liquid pipe, suction gas pipe, HP/
LP gas pipe, equalizer pipe shutoff valves must be left closed), and charge the refrigerant of the
additional charging amount from the liquid side shutout valve service port.
4. If the additional charging amount was charged fully, close the valve B and go to step 6.
If the additional charging amount was not charged fully, close the valve B and go to step 5.
5. Perform the refrigerant charging following [ Automatic refrigerant charging operation
procedure ] as shown below. Charge the remaining refrigerant of the additional charging
amount .
NOTE:
For performing the automatic refrigerant charging operation, the push button on the PC-board
(A1) of outside unit is used. (See figure 29.)
The refrigerant is charged from the refrigerant charge port via the valve A. (See figure 31.) For
operating the push button and opening or closing the valves, follow the procedure.
During Automatic refrigerant charging operation, the system will select charging mode (cooling
mode or heating mode) by the temperature condition as follows.
When charging in cooling mode, the system will stop operation when the required amount of
refrigerant is charged.
During charging in heating mode, a person must manually close valve A and stop operation.
Beforehand, check the remaining refrigerant that is needed to charge based on the
additional
charging amount in step 2 and the charged amount in step 3.
The refrigerant will be charged about 66 lb in one hour at outdoor temp. 86°F DB (about 26 lb at
outdoor temp. 32°F DB).
During Automatic refrigerant charging operation, you can stop the operation forcibly by pushing
