•
Be especially careful when managing the tools.
- If dust, dirt, or water gets in the refrigerant cycle, the refrigerant may deterio-
rate.
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 instru-
ments, 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 significantly reduce the performance of
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 conditioner
to operate erroneously, or fail to operate. On the other hand, the air condi-
tioner 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 or BC controller. Perform collec-
tive drainage work together with the outdoor unit, as required.
1.4. Before getting installed (moved) - elec-
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 may cause the cable to break and generate heat and cause a fire.
•
Install an leak circuit breaker, as required.
- If an 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, generate heat, and cause a fire.
•
Use only a circuit breaker and fuse of the specified capacity.
- A fuse or circuit breaker of a larger capacity, a steel or copper wire may result
in a general unit failure or fire.
2. Selecting an installation site
2.1. Installation site
•
Place not exposed to rain (BC controller is a special machine for indoor use.)
•
Place with large enough service space
•
Place in which refrigerant pipes can be provided within the limitations
•
Place not exposed to direct radiant heat from other heat sources
•
Do not install the unit in any oily steamy place or near any machine that gener-
ates high frequencies. Doing so may cause a risk of fire, erroneous operation
or dew drop
•
Place with less noise effect generated from other units
•
Place in which water piping, refrigerant piping and electrical wiring can be
done easily
•
Avoid places exposed to the generation, inflow, accumulation or leakage of
flammable and sulfuric gases
•
Place in which a downward pitch of more than 1/100 can be taken for drain
piping
1. For hanging from the ceiling [Fig. 2.1.1] (P.2)
•
Provide a inspection hole 450 mm square to the ceiling surface as shown in
[Fig. 2.2.1] (P.2).
•
Above the ceiling of corridor, bath room, etc., where persons are not regularly
there (Avoid installing at around center of the room).
•
Place with strength to the degree that hanging bolts can be mounted (that
sustains a pull-out load of 60 kg per bolt)
•
Be sure to install BC controllers at level.
•
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 injury
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 causing damage to furniture
and other possessions.
•
Be very careful about product transportation.
- One person should not carry the product as it weighs more than 20 kg.
- Some products use PP bands for packaging. Do not use any PP bands as a
means of transportation. It is dangerous.
- Do not touch the heat exchanger fins. Doing so may cut your fingers.
- When transporting the outdoor unit, support it at the specified positions on
the unit base. Also support the outdoor unit at four points so that it cannot
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.
1.5. Before starting the test run
Caution:
•
Turn on the power at least 12 hours before starting operation.
- Starting operation immediately after turning on the main power switch can
result irreversible damage to internal parts. Keep the power switch turned on
during the operational season.
•
Do not touch the switches with wet fingers.
- Touching a switch with wet fingers can cause electric shock.
•
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 flowing 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 five minutes before turning off the power. Otherwise,
water leakage and trouble may occur.
2. For stacking on a rack [Fig. 2.1.1] (P.2)
•
Place in which sufficient space can be obtained around a rack
•
Place with floor strength that sustains the entire weight
Warning:
Be sure to install the unit in a place that well sustains the entire weight.
If there is a lack of strength, it may cause the unit to fall down, resulting in an
injury.
Caution:
Be sure to install the unit at level.
