4-2. Evacuation procedures：
EVACUATION PROCEDURES
Connect the refriger ant pipes (both the l iquid and gas
pipes ) between the indoor and the outdoor units .
Remove the servi ce port cap of the stop valve on the side of the
outdoor unit gas pipe. (The stop valve will not work in its initial
state fresh out of the factory (totally closed with c ap on).
Connect the gage manifold v alve and the vacuum pump to the service port of the stop valve on
the gas pipe si de of the outdoor unit.
Run the vacuum pum p for m ore than 15 m inutes and at this ti m e c onfirm that the pres sure gage
indi cates -0.1 M pa (-76 cmHg).
Check the vacuum with the gage manifold valve, then c lose the gage manifold valve, and stop the
vacuum pum p.
Leave i t as is for one or two m inutes .Make s ure the pointer of the gage manifol d v alve r em ains
in the sam e pos ition.

Remove the gage manifold valve quickly from the service port of the stop valve.
After refri gerant pipes are connec ted and ev acuated, fully open al l stop val ves

Operating without fully opening lowers the performance and c auses troubl e.
