Note: be sure there is no refrigerant inside the system and power supply has been cut off before
replacement.
Steps
7. Put back the front
panels.
Note: there would be trapped oil inside the compressor during replacement, which would not affect its
reliability but increase resistance to the rotors and then consume more power. In order to expel it, it would
be better to install another valve at the lower point of the suction line. After that, run the compressor for
ten minutes and then open this valve until no oil comes out. Repeat this operation twice for normal oil
level.
Note: be sure power supply has been cut off and refrigerant has been reclaimed before replacement.
Steps
1. Remove the front
panel.
2. Record the
direction of 4-way
valves before
remove it. It is
prohibited to take
other units as
reference when
removing 4-way
valves of a multi-
system unit.
