5.1. The Procedure of Connecting Pipes

5.1.1 Measure the necessary length of the connecting pipe, and use the following process.

1) Connect the indoor unit at ﬁrst, then the outdoor unit. a. Use a pipe

bender to form the radius of the pipework.

CAUTION

1. Cover the surfaces of the ﬂare pipe and the joint nuts

with oil, and tighten it for 3~4 turns with hands before fasten the ﬂare nuts.

2. Be sure to use two wrenches simultaneously when you

connect or disconnect the pipes

2) The stop valve of the outdoor unit should be closed tightly (as

original supplied). Every time you operate it, ﬁrst loosen the nuts at the part of stop valve, then connect the ﬂare pipe immediately (within 5minutes). If the nuts have been loosened for a long time, dust and other impurities may enter the pipe system and may cause malfunction later. Ensure that air is expelled from out of the pipe with refrigerant before connection.

3) Remove the air (refer to the “Expel The Air”) after connecting the

refrigerant pipe with the indoor unit and the outdoor unit. Then fasten the nuts at the service-points.

■ Notices For Benable pipe.
