Installation of the Unit

Note: For the large-sized unit, it has the service port for both the gas valve and the liquid
valve.
During evacuation, it is available to connect two hoses of the manifold valve assembly to two
service ports to quicken the evacuating speed.

Refrigerant suitable for a piping length of 5m is charged in the outdoor unit at the factory.
When the piping is longer than 7m, additional charging is necessary.
For the additional amount, see Table 7.

When the height difference between the indoor unit and outdoor unit is larger than 10 meters,
an oil bend should be employed for every 6 meters.
