8. Precautions
for
connecting hoses and tubes in an air condi-
tioner circuit
1) Disconnection
k
Although the refrigerant (refrigerant
gas: R134a) used on the machine's air
conditioner is less destructive to the
ozone layer for environmentally friend-
liness, it is not allowed to be released
into the atmosphere as is. Whenever
disconnecting the air conditioner gas
circuit, be sure to recover the refriger-
ant gas to reuse it.
a Ask a qualified person for collection and
charge of the refrigerant (R134a).
a Never release the refrigerant (R134a) to
the atmosphere.
k
If the refrigerant gas gets in your eyes
or contacts your skin, you may lose
your sight or your skin may be frozen.
Whenever recovering or adding refrig-
erant gas, you must put on safety
glasses,
safety
sleeved clothes.
The refrigerant gas must be recovered
and added by a qualified person.
2) Connection
1] When installing the air conditioner circuit
hoses and tubes, take care that dirt, dust,
water, etc. will not enter them.
2] When connecting the air conditioner
hoses and tubes, check that O-rings (1)
are fitted to their joints.
3] Check that O-ring (1) is free from flaw and
deterioration.
4] When connecting the refrigerant piping,
apply compressor oil for refrigerant
(R134a) (DENSO: ND-OIL8, VALEO
THERMAL SYSTEMS: ZXL100PG
(equivalent to PAG46)) to its O-rings.
