Air Evacuation

Note on Adding Refrigerant

Some systems require additional charging depending on pipe lengths. The standard pipe length varies

according to local regulations. For example, in North America, the standard pipe length is 7.5m (25’).

In other areas, the standard pipe length is 5m (16‘). The refrigerant should be charged from the service

port

on the outdoor unit’s low pressure valve.

The additional refrigerant to be charged can be

calculated using the following formula:

CAUTION

DO NOT mix refrigerant types.

For R290 refrigerant unit, the total amount of refrigerant to be charged is no more than:

387g(<=9000Btu/h), 447g(>9000Btu/h and <=12000Btu/h), 547g(>12000Btu/h and <=18000Btu/h),

632g(>18000Btu/h and <=24000Btu/h).
