Additional charge

The refrigerant is pre-charged in the outdoor unit. If the

piping length is less than 7.62m (25ft), then additional charge

after vacuuming is not necessary. If the piping length is more

than 7.62m (25ft), then use the additional charge valve as

indicated in the table.

Charge operation

This operation must be done by using a gas cylinder and a

precise weighing machine. The additional charge is topped-

up into the outdoor unit using the suction valve via the ser-

vice port.

Connect the low pressure side of the charging gauge to

the suction service port center of the cylinder tank and
