e
Press Mode button “BS1” once and reset “Setting Mode 2”.
3.2.7 Setting of Vacuuming Mode
In order to perform vacuuming operation at site, fully open the expansion valves of indoor and
outdoor units and turn on some solenoid valves.
[Operating procedure]
c
With
Setting Mode 2
while the unit stops, set “Refrigerant recovery / Vacuuming mode” to

valves open.
(H2P blinks to indicate the test operation, and the remote controller displays "Test
Operation" and "Under centralized control", thus prohibiting operation.)
After setting, do not cancel “Setting Mode 2” until completion of Vacuuming operation.
d
Use the vacuum pump to perform vacuuming operation.
e
