Expel 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 repair-points.
The bending angle should not exceed 90 .
Bending position is preferably in the bendable pipe. The larger the better it is.
Do not bend the pipe more than three times.
o
Cut out a desired concave at the bending part of the insulating pipe. Then expose the pipe
(cover it with tapes after bending).
To prevent collapsing or deforming, please bend the pipe at its biggest radius.
Use bender to get a small radius pipes.
Be sure use the same insulating materials when you buy the brass pipe. (Thickness over 9mm
in general)
NOTICES FOR BENDABLE PIPE
BEND THE CONNECTING PIPE OF SMALL WALL THICKNESS
USE THE MARKET BRASS PIPE
3. Then, open the stem of stop valves of the outdoor unit to make the refrigerant pipe connecting
the indoor unit with the outdoor unit in fluent flow.
4. Be sure of no leakage by checking it with leak detector or soap water.
5. Necessary refrigerant capacity:
6. Cover the joint of the connecting pipe to the indoor unit with the soundproof insulating sheath
(fittings), and bind it well with the tapes to prevent leakage.
