FOR SL 30 / 40 / 50 / 60 C/CR & 4SL 30 / 40 / 50 / 60 C/CR:
The refrigerant is pre-charged in the outdoor unit. If the piping
length is less than 7.6 m, additional charge after vacuuming is not
necessary. When the piping length is more than 7.6 m, use the
table below.
Additional Charge Operation
This operation must be done by using gas cylinder and a precise
weighing machine obligatorily. The additional charge is top up
into the outdoor unit by suction valve via service port.
• Remove the service valve plug.
• Connect the low pressure manifold to the suction service port,
center manifold to the cylinder tank and close the high pressure
manifold (see figure below).
Purge all the flexible hose with refrigerant gas.
• Start the air conditioner unit.
• Open the gas cylinder and low pressure manifold valve.
• When the required refrigerant quantity is pumped in the unit,
close the low pressure manifold and the gas cylinder valve.
• Disconnect the manometer and the gas cylinder. Place back the
service port cap.
