Table 2
• Refer to “Table 2” to determine the proper tightening torque.
Not recommendable but in case of emergency
You must use a torque wrench but if you are obliged to install
the unit without a torque wrench, you may follow the installation
method mentioned below.
When you keep on tightening the flare nut with a spanner, there
is a point where the tightening torque suddenly increases.
From that position, further tighten the flare nut the angle shown
below:
Table 3
After the work is finished, make sure to check that there is
no gas leak.
• Make absolutely sure to execute heat insulation works on
the pipe-connecting section after checking gas leakage by
thoroughly studying the following figure and using the
attached insulation for fitting (6) and (7). (Fasten both ends
with the clamps (4).) (Refer to Fig. 23)
• Wrap the sealing pad (9) only around the insulation for the
joints on the gas piping side.
CAUTION
For local insulation, be sure to insulate all the way to the piping
connections inside the unit.
Exposed piping may cause leaking or burns on contact.
6-2 For upward and rightward running piping
• Upward and rightward running piping are easily rigged with
the optional connecting elbow kit.
• For upward running piping, detach the pipe hole cover.
• Once piping are rigged, cut the pipe hole cover to size and
reattach. Use scissors for cutting.(Refer to Fig. 24)
Since there exists a possibility that small animals and
insects might get inside the indoor unit, attach the wir-
ing through covers and make sure there are no gaps in
the through holes by applying putty or insulation (field
supplied).
• When doing this, block any gaps between the piping pene-
tration lid and the piping using putty to prevent dust from
entering the indoor unit.
CAUTION
CAUTION TO BE TAKEN WHEN BRAZING REFRIGERANT
PIPING
“Do not use flux when brazing refrigerant piping. Therefore, use
the phosphor copper brazing filler metal (BCuP-2:JIS Z 3264/B-
Cu93P-710/795:ISO 3677) which does not require flux.”
(Flux has extremely harmful influence on refrigerant piping sys-
tems. For instance, if the chlorine based flux is used, it will
cause piping corrosion or, in particular, if the flux contains fluo-
rine, it will damage the refrigerant oil.)
• Before brazing local refrigerant piping, nitrogen gas shall be
blown through the piping to expel air from the piping.
If you brazing is done without nitrogen gas blowing, a large
amount of oxide film develops inside the piping, and could
cause system malfunction.
• When brazing the refrigerant piping, only begin brazing after
having carried out nitrogen substitution or while inserting
nitrogen into the refrigerant piping. Once this is done, con-
nect the indoor unit with a flared connection.
• Nitrogen should be set to 0.02 MPa with a pressure-reduc-
ing valve if brazing while inserting nitrogen into the piping.
(Refer to Fig. 25)
Fig. 25
CAUTION
Do not use anti-oxidants when brazing the piping joints.
Residue can clog piping and break equipment.
7. DRAIN PIPING WORK
7-1 Rig drain piping (Refer to Fig. 26)
As for drain piping work, perform piping in such a manner that
water can be drained properly.
As for drain piping, the connection can be made from three dif-
ferent directions.
• Employ a pipe with either the same diameter or with the
diameter larger (excluding the raising section) than that of
the connecting piping (PVC pipe, nominal diameter 20mm,
outside diameter 26mm).
• Keep the drain piping short and sloping downwards at a gra-
dient of at least 1/100 to prevent air pockets from forming.
(Refer to Fig. 27)
CAUTION
Water pooling in the drainage piping can cause the drain to clog.
