1.2. Precautions for devices that use
R410A refrigerant
Caution:
• Do not use the existing refrigerant piping.
- The old refrigerant and refrigerator oil in the existing piping contains a
large amount of chlorine which may cause the refrigerator oil of the new
unit to deteriorate.
• Use refrigerant piping made of C1220 (Cu-DHP) phosphorus deoxidized
copper as specified in the JIS H3300 "Copper and copper alloy seam-
less pipes and tubes". In addition, be sure that the inner and outer
surfaces of the pipes are clean and free of hazardous sulphur, oxides,
dust/dirt, shaving particles, oils, moisture, or any other contaminant.
- Contaminants on the inside of the refrigerant piping may cause the refrig-
erant residual oil to deteriorate.
• Store the piping to be used during installation indoors and keep both
ends of the piping sealed until just before brazing. (Store elbows and
other joints in a plastic bag.)
- If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and
compressor trouble may result.
• Use ester oil, ether oil or alkylbenzene (small amount) as the refrigera-
tor oil to coat flares and flange connections.
- The refrigerator oil will degrade if it is mixed with a large amount of mineral
oil.
• Use liquid refrigerant to fill the system.
- If gas refrigerant is used to seal the system, the composition of the refrig-
erant in the cylinder will change and performance may drop.
• Do not use a refrigerant other than R410A.
- If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may
cause the refrigerator oil to deteriorate.
• Use a vacuum pump with a reverse flow check valve.
- The vacuum pump oil may ��back into the refrigerant cycle and cause
the refrigerator oil to deteriorate.
• Do not use the following tools that are used with conventional refriger-
ants.
(Gauge manifold, charge hose, gas leak detector, reverse flow check valve,
refrigerant charge base, vacuum gauge, refrigerant recovery equipment.)
- If the conventional refrigerant and refrigerator oil are mixed in the R410A,
the refrigerant may deteriorated.
- If water is mixed in the R410A, the refrigerator oil may deteriorate.
- Since R410A does not contain any chlorine, gas leak detectors for conven-
tional refrigerants will not react to it.
• Do not use a charging cylinder.
- Using a charging cylinder may cause the refrigerant to deteriorate.
• Be especially careful when managing the tools.
- If dust, dirt, or water gets in the refrigerant cycle, the refrigerant may deteriorate.
1.3. Before getting installed
Caution:
• Do not install the unit where combustible gas may leak.
- If the gas leaks and accumulates around the unit, an explosion may result.
• Do not use the air conditioner where food, pets, plants, precision in-
struments, or artwork are kept.
- The quality of the food, etc. may deteriorate.
• Do not use the air conditioner in special environments.
- Oil, steam, sulfuric smoke, etc. can �������
the air conditioner or damage its parts.
• When installing the unit in a hospital, communication station, or similar
place, provide sufficient protection against noise.
- The inverter equipment, private power generator, high-frequency medical
equipment, or radio communication equipment may cause the air condi-
tioner to operate erroneously, or fail to operate. On the other hand, the
air conditioner may affect such equipment by creating noise that disturbs
medical treatment or image broadcasting.
• Do not install the unit on a structure that may cause leakage.
- When the room humidity exceeds 80% or when the drain pipe is clogged,
condensation may drip from the indoor unit. Perform collective drainage
work together with the outdoor unit, as required.
• The indoor units should be installed more than 2.5 m [9 ft] from floor.

trical work
Caution:
Ground the unit.
- Do not connect the ground wire to gas or water pipes, lightning rods, or
telephone ground lines. Improper grounding may result in electric shock.
Install the power cable so that tension is not applied to the cable.
- Tension ��������������������������������
Install a leak circuit breaker, as required.
- If a leak circuit breaker is not installed, electric shock may result.
Use power line cables of sufficient current carrying capacity and rating.
- Cables that are too small may leak, gen��������������
Use only a circuit breaker and fuse of the specified capacity.
- A fuse or circuit breaker of a larger capacity or a steel or copper wire may
��������������������
Do not wash the air conditioner units.
- Washing them may cause an electric shock.
Be careful that the installation base is not damaged by long use.
- If the damage is left uncorrected, the unit may fall and cause personal in-
jury or property damage.
Install the drain piping according to this Installation Manual to ensure
proper drainage. Wrap thermal insulation around the pipes to prevent
condensation.
- Improper drain piping may cause water leakage and damage to furniture
and other possessions.
Be very careful about product transportation.
- Only one person should not carry the product if it weighs more than 20 kg
[44 lb].
- Some products use PP bands for packaging. Do not use any PP bands for
a means of transportation. It is dangerous.
- �������������������
- When transporting the outdoor unit, suspend it at the ����� positions
on the unit base. Also support the outdoor unit at four points so that it can-
not slip sideways.
Safely dispose of the packing materials.
- Packing materials, such as nails and other metal or wooden parts, may
cause stabs or other injuries.
- Tear apart and throw away plastic packaging bags so that children will not
play with them. If children play with a plastic bag which was not torn apart,
they face the risk of suffocation.
Caution:
Turn on the power at least 12 hours before starting operation.
- Starting operation immediately after turning on the main power switch can
result in severe damage to internal parts. Keep the power switch turned on
during the operational season.
Do not touch the switches with wet fingers.
- Touching����������������
Do not touch the refrigerant pipes during and immediately after opera-
tion.
- During and immediately after operation, the refrigerant pipes are may be
hot and may be cold, depending on the condition of the refrigerant �� -
ing through the refrigerant piping, compressor, and other refrigerant cycle
parts. Your hands may suffer burns or frostbite if you touch the refrigerant
pipes.
Do not operate the air conditioner with the panels and guards removed.
- Rotating, hot, or high-voltage parts can cause injuries.
Do not turn off the power immediately after stopping operation.
- Always wait at least �� minutes before turning off the power. Otherwise,
water leakage and trouble may occur.
