Installing Connecting Pipe
1. The tapered end of the connecting pipe must be in line with the corresponding tape face of the valve
joint.
2. Tighten the nut manually on the connecting pipe and then use a wrench to tighten it fully.
Caution: Excess torque may damage the nut.
Notes:
Connect the connecting pipe to the indoor unit first
and then connect it to the outdoor unit. Pay
attention to the bending and layout when preparing
the connecting pipe in order not to harm it. Do not
screw the joint nut too tightly, otherwise leakage will
be caused.
