8.3. Refrigerant collecting (pump down) (Fig. 8-3)

The refrigerant collecting function is available by performing the following procedure.

1 Close the 2 liquid stop valves and the cylinder/hydro unit side gas valve.

Only the indoor unit side gas valve remains open.

2 Connect the 2 gas stop valve service ports with a hose.

3 Turn on the main power and wait for 3-4 minutes.

4 Press the SWP button on the outdoor controller board, then the refrigerant collecting operation starts.

5 After conﬁ rming the low pressure is lowered to 0 MPa (gauge), close the indoor unit side gas valve.

The refrigerant collecting operation stops automatically in 5 minutes.

6 Turn off the main power.

Warning:

Do not disconnect extension pipes during the refrigerant collecting operation is running.

If you open the stop valves to the air during the compressor is running, the pressure could be abnormal high level and this may cause a rupture

of the compressor or other hazardous situation.

* Use a refrigerant recovery machinery if the refrigerant collecting is not completed in case of long pipe length or too much refrigerant contained.
