Vacuuming and Charging
The pre-charged outdoor unit does not need any vacuuming or charging. However once it is connected, the
connecting pipe line and the indoor unit need to be vacuumed before releasing the R22/R407C/R410A from
the outdoor unit.
1. Open the service port core cap.
2. Connect pressure gauge to the service port.
3. Connect the line to vacuum pump. Open the charging manifold valve and turn the pump on. Vacuum to -0.1
MPa (-760mmHg) or lower. (Evacuation time varies by the pump but averagely in 1 hour).
Filter Dryer
(Mclecular-Sieve Type
Note : R22 - Nil
R410A - Nil
4. After evacuation, unscrew the spindle (diagram B) for the gas to run to indoor unit.
Additional Charge
• The refrigerant gas is charged in the outdoor unit and, if the piping length is 7.6m, additional charge of the
refrigerant after vacuuming is not necessary.
• When the piping length is more than 7.6m, additional refrigerant charge (g) per additional 1m length as
tabulated:
