Test Operation
•
Calculate a necessary additional refrigerant charging amount according to the procedure for
calculation shown below.
*
Procedure for calculating additional refrigerant charging amount (Unit: 0.1 kg)
Correction amount with indoor unit
Correction amount with a total capacity of indoor units
•
If there is a refrigerant shortage, charge a liquid refrigerant through the stop valve service
port with the stop valves of liquid and those of gas closes after the completion of vacuum
drying.
•
If the refrigerant charging is still insufficient, "turn ON the power supply" following the
information on the page 160 ~.
Check on amount of refrigerant
charge
Is a proper quantity of refrigerant charged?
The following method is available for additional charging of
refrigerant.
(1) Calculate additional refrigerant quantity.
