1.2. Before getting installed

Caution:
• 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 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 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 models should be installed the ceiling over than 2.5 m from
floor.
1.3. 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 or a steel or copper wire may
result in a general unit failure or fire.
• 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.
- Some products use PP bands for packaging. Do not use any PP bands for
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, suspend it at the specified 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.

1.4. 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 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 a switch with wet fingers can cause electric shock.
• 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.
• When water has been supplied to the water pipework, purge the system
of air. The details of air purging can be found separately in the water
circuit maintenance manual.
- Details are described in section [9] "Instructions for debris removal opera-
tion" under chapter IX Troubleshooting in the Service Handbook for the
HBC.
- Refer to Fig. 1.4.1 for the position of the air vent valve on the indoor unit.
