Installing the air conditioner
7. Pipe vacuuming
1) Remove the cap on the gas side service port of service valve.
2) Connect the manifold gauge on the service port and the vacuum pump
and perform vacuuming for more than15 minutes.
3) Make sure that pressure gauge shows -0.1MPa (-760mmHg), then close
the valve on manifold gauge and turn off the vacuum pump.
4) Check if the pressure on the gauge remains same for about 2~3 minutes.
(If there's change in the pressure of the manifold gauge, it means that
there's a leakage and therefore you must check for leaking part.)
8. Charging refrigerant
1) Charge the refrigerant according to the length of the pipe. (When
the pipe length exceeds the standard pipe length of 5m, charge the
additional amount of refrigerant according to the exceeding length.
However, if the pipe length is shorter than the standard length, you do
not need to charge the additional refrigerant.)
Model name
APV36M0* Series
2) After charging the refrigerant, disconnect the manifold gauge from
service port and tighten the cap nut. (Preventing leakage)
9. Installing an oil trap
Check the following list and install an oil trap.
- Install an oil trap only when the outdoor unit is at a higher level than the
indoor unit.
- Based on cooling operation, install it on the gas side pipe only.
- Install the oil trap only in between the outdoor unit and the first branch
joint and it should be installed at every 10m.
- Radius of curvature (R) on the oil trap are as follows:
Pipe diameter [D(mm)]
ø 12 . 7 0
ø 15 . 8 8
ø 19 . 0 5
ø 22 . 2 3
ø 25 . 4 0
ø 28 . 6 0
ø 31 . 7 5
- Height of an oil trap (H): 4R ≤ H ≤ 6R
