CAUTION
Insulation of
piping must be carried out up to the
connection inside the casing.
If
the piping
is
e
xposed
to the
atmospher
e, it may
cause
s
weating, burn
due
to touching the piping, electric
sho

6. REFRIGERANT PIPING WORK
•
For the
outdoor
unit
ref
rigerant piping, re
f
er to the
installation
manual
attached
to the
outdoor
unit.
•
Carry out
insulation
of
both
gas
and
liquid
ref
rigerant piping
securel
y.
If
not
insulated,
it may
cause
water leakage. For
gas
piping,
use
insulation
material
of
which heat
resistant
temperature
is
not
less
than 120°C.
For
use
under
high
humidit
y,
strengthen
the
insulation
material
f
or
ref
rigerant piping.
If
not
strengthened,
the
surf
ace
of
insulation
material may
s
weat.
•
Be
f
ore
installation
work, make
sure
that the
ref
rigerant
is
R410A.
(Unless
the
ref
rigerant
is
R410A, the nor mal
operation cannot be e
xpected.)
CAUTION
This air conditioner is a dedicated model for new re-
frigerant R410A. Make sure to meet the require ments
shown below and carry out installation work.
•
Use dedicated piping cutters and
tools for
R410A.
•
When making a
connection, coat the
inner
surface only with ether oil or ester oil.
•
Use only the
nuts attached to the air conditioner.
If other
nuts are used, it may cause refrigerant
leakage.
•
To prevent contamination or moisture from getting
into the piping, take measures such as pinch ing or
taping the pipings.
Do not mix substance other than the
refriger-
ant such as air into the refrigeration circuit.
If the refrigerant leaks during the work, ventilate the
room.
•
The re
f
rigerant i
s
pre-charge
d
in the out
d
oor unit.
•
When connecting the piping
s
to the air con
d
itioner, make
s
ure to u
s
e a
s
panner an
d
a torque wrench a
s
s
hown in
Fig. 9.
•
For the
d
ime
ns
ion o
f
part an
d
the tightening torque,
re
f
er to the Table 2.
•
When making a
connection, coat the
inner
s
ur
f
ace only with ether oil or e
s
ter oil.
(Refer to Fig. 10)
Then, turn the
nut 3 to 4 time
s
with your han
d
an
d
s
crew in the nut.
