Wiring

For construction convenience, before laying pipes, use insulation material to insulate the pipes to be deal
with, at the same time, at two ends of the pipe, remain some length not to be insulated, in order to be welded
and check the leakage after laying the pipes.
5.2.3. Insulate for the jointing area, expanding area and the flange area
①
Insulate for the jointing area, expanding area and the flange area should be done after checking leakage
of the pipes
② Make sure there's no clearance in the joining part of the accessorial insulation material and local
preparative insulation material.
5.3 Drainage pipe insulation
The connection part should be insulated, or else water will be condensing at the non-insulation part.
5.4 Note
5.4.1 The jointing area, expanding area and the flange area should be heat insulated after passing the
pressure test
5.4.2 The gas and liquid pipe should be heat insulated individually, the connecting part should be heat
insulated individually.
5.4.3 Use the attached heat-insulation material to insulate the pipe connections (pipes' tie-in ,expand nut ) of
the indoor unit
