(2) Caution about Outdoor Unit Installation
1.
Align the outdoor units and locate large capacity Master (A) on the indoor unit side. Piping length between Piping
Connection Kit 1 and each outdoor unit should be less than 10m.
2.
Place the piping connection kit lower than the outdoor unit piping connection.
In case that the piping connection kit is placed higher than the outdoor unit piping connection, keep 300mm (max.)
between the piping connection kit and the bottom of the outdoor unit. Also, provide an oil trap (min.200mm) between the
piping connection kit and the outdoor unit.
