(2) On completion of installation work,
check that there is no
gas leakage
.
(3) Refer to the following illustration and be sure to perform
heat insulation work on the piping joints after gas leakage
checks.
(Refer to Fig. 6)
• Use the insulation for fitting (4) and (5) provided to the
liquid piping and gas piping, respectively, and conduct
heat insulation work.
(Tighten both edges of the insulation for fitting (4) and (5)
for each joint with the clamp (8).)
• Make sure that the joint of the insulation for fitting (4) and
(5) for the joint on the liquid piping and gas piping side
faces upward.
• Wrap the middle sealing material (7) around the insula-
tion for fitting (4) and (5) for the joint (flare nut part).
CAUTION
• Be sure to perform the heat insulation of the local piping
up to the piping joint.
If the piping is exposed, dew condensation may result. Fur-
thermore, a burn may be caused if a human body comes in
contact with the piping.
• Perform nitrogen substituent or apply nitrogen into the
refrigerant piping (see NOTE 1) in the case of refrigerant
piping blazing (see NOTE 2). Then perform the flare con-
nection of the indoor unit.
(Refer to Fig. 7)
CAUTION
• Do not use any antioxidant at the time of piping blazing.
The piping may be clogged with a residual antioxidant and
parts may malfunction.
NOTE
1. At the time of blazing, set the pressure of nitrogen to
approximately 2.9 PSI (close to the pressure of a breeze
coming in contact with the cheek) with a pressure-reduc-
ing valve.
2. Do not use flux at the time of blazing and connecting the
refrigerant piping. Use a copper phosphorus brazing alloy
(BCuP-2/BCu 93P-710/795), which does not require flux,
for blazing.
(Flux has a bad influence on the refrigerant piping. Chlo-
rine-based flux will cause piping corrosion. Furthermore, if
it contains fluorine, the flux will deteriorate refrigerant oil.)
• As for the branching of the refrigerant piping or refrigerant,
refer to the installation manual provided with the outdoor unit.
7.
DRAIN PIPING WORK
(1) Conduct drain piping work.
Check that the piping
ensures proper draining.
• Make sure that the diam-
eter of the piping exclud-
ing the rising part is the
same as or larger than
the diameter of the con-
necting pipe (vinyl chloride pipe with an outer diameter
of 1-1/4 in. and a nominal inner diameter of 31/32 in.).
• Make sure that the piping is short enough
with a down-
ward slope of at least 1/100
and that there is no air
bank formed. No drain trap is required.
