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.

Caution

•

• R410A must be charged as liquid. Usually R410A cylinder is equipped with a dip-pipe for liquid withdrawal. If there is

nodip-pipe, the cylinder should be inverted so as to withdraw liquid R410A from the valve.

• Do not top-up when servicing leak, as this will reduce the unit performance. Vacuum the unit thoroughly and then

charge the unit with fresh R410A according to the amount recommended in the specification.
