2.2
Refrigerant pipe
l)
The-refrigerant pipe must be installed by the special
refrigerant dishibutor
made by our company (purchase).
2)
The refrigerant pipe must
use
the pipe
with
specified diameter
and
wall
thickness.
3)
The
welding of
the copper
pipe
must
be
performed
with nihogen-filled protection. Before welding,
the copper
pipe
must be
filled with
the
nitrogen
of
0.2kgflcnt'. After welding,
the nitrogen must
be
cut
offuntil
G
copper pipe
is
thoroughly
cooled down.
4)
The refrigerant pipe must be treatcd
with
themal
insulation.
5)
After
the refrigerant pipe is installed
and
before the air tightness test and vacuumization
are
performed, the
indoor
uit
cannot
be
power-on.
2.3
Air
tightness test
After
the
refrigerant pipe
is
instalied,
nitrogen
of40kgf/crf 1+.oula;
must be
filled
from
the gas side and
liquid
side
simultaneously for
24-hour
air
tightness
test.
2.4
Vacuumizing
After
the air tightness test, vacuumization
(0.lMPa)
must be
perfomed from
both thc
gas
side and the
liquid
side simultaneously.
2.5 Refilling
of refrigerant
l)
The

by
the diarneter and
length (actual length)
of
the pipe
at the
liquid
sides
of
the
indoor
and
outdoor
unlts.
2)
The
refilling
volume of
refiigermt,
diameter and length
(actual length) of
liquid
pipe,
and
height difference
of
the
indoor
and outdoor
units
shall be
recorded
into
the
me confirmation
table of the outdoor
unit
(on the cover plate
of electronic
conlol
box) for
