Test Operation
3. Open the valve C (See the figure 31. The valve A, B and the liquid and gas side shutout
valve must be left closed), and charge the refrigerant of the “additional charging amount”
from the liquid side shutout valve service port.
If the “additional charging amount” was charged fully, close the valve C and go to step 5.
If the “additional charging amount” was not charged fully, go to step 4.
4. Perform the refrigerant charging operation following [Refrigerant charging operation
procedure] as shown in page 153, and charge the remaining refrigerant of the “additional
charging amount”. For performing the refrigerant charging operation the push button on the
PC-board (A1P) of outdoor unit (Incase of multi system master unit) are use. (See the figure
32) In addition, the refrigerant are charged from the refrigerant charge port via the valve A.
(See the figure 33)
For operating the push button and opening and closing the valve, follow the work procedure.
Note:
The refrigerant will be charged about 22kg in one hour at outdoor temp. 30°C DB (6kg at 0°C
DB).
If you need to speedup in case of multi system, connect the refrigerant cylinders to each
outdoor unit as shown in the figure 33.
