Since there is a possibility that oil may be collected on a stop machine side, install piping
between outdoor units to go to level or go up to an outdoor unit, and to make a slope.
When the piping length between the multi connection kits or between multi connection kit and
outdoor unit is 2m or more, prepare a vertical projection part (200mm or more as shown below) only
on the gas pipe line location less than 2m from multi connection kit.
The projection part between multi connection piping kits
