Precautions for Handling Units for Use with R32
CAUTION
Do not use the existing refrigerant piping
• The old refrigerant and refrigerator oil in the existing
piping contain a large amount of chlorine, which will
cause the refrigerator oil in the new unit to deteriorate.
• R32 is a high-pressure refrigerant, and the use of the
existing piping may result in bursting.
Use a vacuum pump with a reverse-flow check valve.
• If other types of valves are used, the vacuum pump
oil will flow back into the refrigerant cycle and
cause the refrigerator oil to deteriorate.
Keep the inner and outer surfaces of the pipes clean
and free of contaminants such as sulfur, oxides, dust/dirt
shaving particles,oils,and moisture.
• Contaminants inside the refrigerant piping will cause the
refrigerant oil to deteriorate.
Do not use the following tools that have been used
with the conventional refrigerants. Prepare tools that
are for exclusive use with R32.
(Gauge manifold, charging hose, gas leak detector,
reverse-flow check valve, refrigerant charge
base,vacuum gauge, and refrigerant recovery
equipment.)
• If refrigerant and/or refrigerant oil left on these tools
are mixed in with R32, or if water is mixed with
R32, it will cause the refrigerant to deteriorate.
• Since R32 does not contain chlorine, gas-leak
detectors for conventional refrigerators will not
work.
Store the piping to be used during installation indoors,
and keep both ends of the piping sealed until immediately
before brazing.(keep elbows and other joints wrapped in
plastic.)
• If dust, dirt, or water enters the refrigerant cycle, it may
cause the oil in the unit to deteriorate or may cause the
compressor to malfunction.
Do not use a charging cylinder.
• The use of charging cylinder will change the
composition of the refrigerant and lead to power
loss.
Use a small amount of ester oil, ether oil, or alkylbenzene
to coat flares and flange connections.
• A large amount of mineral oil will cause the refrigerating
machine oil to deteriorate.
Exercise special care when handling the tools.
• An introduction of foreign objects such as dust, dirt
or water into the refrigerant cycle will cause the
refrigerating machine oil to deteriorate.
Use liquid refrigerant to charge the system.
• Charge the unit with gas refrigerant will cause the
refrigerant in the cylinder to change its composition and
will lead to a drop in performance
Only use R32 refrigerant.
• The use of refrigerants containing chlorine(i.e.
R22) will cause the refrigerant to deteriorate.
CAUTION
Do not install the unit in a place where there is a possibility
of flammable gas leak.
• Leaked gas accumulated around the unit may start a fire
or explosion.
When installing the unit in a hospital, take necessary
measures against noise.
• High-frequency medical equipment may interfere
with the normal operation of the air conditioning
unit or the air conditioning unit may interfere with
the normal operation of the medical equipment
Do not use the unit to preserve food, animals, plants,
artifacts, or for other special purposes.
• The unit is not designed to provide adepuate conditions
to preserve the quality of these items.
Do not place the unit on or over things that may not
get wet.
• When humidity level exceeds 80% or when the
drainage system is clogged, indoor units may drip
water.
• Installation of a centralized drainage system for
the outdoor unit may also need to be considered to
prevent water drips from the outdoor units.
Do not use the unit in an unusual environment
• The use of the unit in the presence of a large amount
of oil, steam, acid, alkaline solvents or special types of
sprays may lead to a remarkable drop in performance
and/or malfunction and presents a risk of electric shock,
smoke, fire, or explosion.
• The presence of organic solvents, corroded gas (such as
ammonia,sulfur compounds,and acid may cause gas or
water leak.)
