Important note on refrigerant charge
Some systems require additional charge depending on the length of the piping. The standard pipe leng-
th varies according to local regulations. For example, in North America, the standard
standard pipe length is 7.5 m (23 ft).
In other areas, the standard pipe length is 5m. Refrigerant must be charged from the service port of the
outdoor unit's low pressure valve. The additional refrigerant to be charged can be calculated using the
following formula:
Length of con-
necting pipe (m)
≤ Standard tube Vacuum pump
length
>Standard tube Vacuum pump
length
For the R290 refrigerant unit, the total quantity of refrigerant to be charged must not exceed
greater than: 387g(<=9000Btu/h), 447g(>9000Btu/h and <=12000Btu/h), 547g(>12000Btu/h and
<=18000Btu/h), 632g(>18000Btu/h and <=24000Btu/h).Refrigerant charge per tube length.
VERY IMPORTANT NOTE:
Do not mix refrigerants of different types.
