• 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.

• 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.
