Charge Operation
This operation must be done by using a gas cylinder and a precise weighing machine. The additional charge is topped-up
into the outdoor unit using the suction valve via the service port.
• Remove the service port cap.
• Connect the low pressure side of the charging gauge to the suction service port center of the cylinder tank and close the
high pressure side of the gauge. Purge the air from the service hose.
• Start the air conditioner unit.
• Open the gas cylinder and low pressure charging valve.
• When the required refrigerant quantity is pumped into the unit, close the low pressure side and the gas cylinder valve.
• Disconnect the service hose from service port. Put back the service port cap.

Additional Charge
The refrigerant is pre-charge in the outdoor unit. If the piping length is less than 7.5m, then additional charge after vacuuming
is not necessary. If the piping length is more than 7.5m then use the additional charge value as indicated in the table.
Additional refrigerant charge [g] per additional 1m length as tabulated (for R22 models)
Cooling only
Example:
CE35E & SL35C with 13m piping length, additional piping length is 5.5m. Thus,
Additional charge = 5.5[m] x 38[g/m]
= 209[g]
