The Following Should Always Be Observed For Safety; Hfc 2. Selecting The Installation Location; Outdoor Unit - Mitsubishi Electric MCFH-A24WV Manual De Instalación

1. THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR
SAFETY
• Please provide an exclusive circuit for the air conditioner and do not connect other electrical appliances to it.
Please report to your supply authority or obtain their consent before connecting this equipment to
the power supply system.
• Be sure to read "THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY" before installing
the air conditioner.
• Be sure to observe the cautions specified here as they include important items related to safety.
• The indications and meanings are as follows.
Warning: Could lead to death, serious injury, etc.
Caution: Could lead to serious injury in particular environments when operated incorrectly.
• After reading this manual, be sure to keep it together with the instruction manual in a handy place on
the customer's site.
I Do not install it by yourself (customer).
Incomplete installation could cause injury due to
fire, electric shock, the unit falling or leakage of
water. Consult the dealer from whom you pur-
chased the unit or special installer.
I Install the unit securely in a place which can
bear the weight of the unit.
When installed in an insufficient strong place, the
unit could fall causing injury.
I Use the specified wires to connect the indoor
and outdoor units securely and attach the
wires firmly to the terminal block connecting
sections so the stress of the wires is not ap-
plied to the sections.
Incomplete connecting and fixing could cause a
fire.
I Do not use intermediate connection of the
power cord or the extension cord and do not
connect many devices to one AC outlet.
It could cause a fire or an electric shock due to
defective contact, defective insulation, exceeding
the permissible current, etc.
I Check that the refrigerant gas does not leak
after installation has completed.
If refrigerant gas leaks indoors, and comes into
contact with the fire of a fan heater, space heater,
stove, etc., harmful substances will be generated.
I Earth the unit.
Do not connect the earth to a gas pipe, water
pipe, lightning rod or telephone earth. Defective
earthing could cause an electric shock.
I Do not install the unit in a place where an in-
flammable gas leaks.
If gas leak and accumulate in the area surround-
ing the unit, it could cause an explosion.
I Install an earth leakage breaker depending on
the installation place (Where it is humid).
If an earth leakage breaker is not installed, it could
cause an electric shock.
Warning
I Perform the installation securely referring to
the installation manual.
Incomplete installation could cause a personal
injury due to fire, electric shock, the unit falling or
leakage of water.
I Perform electrical work according to the in-
stallation manual and be sure to use an ex-
clusive circuit.
If the capacity of the power circuit is insufficient
or there is incomplete electrical work, it could
result in a fire or an electric shock.
I Attach the electrical part cover to the indoor
unit and the service panel to the outdoor unit
securely.
If the electrical part cover in the indoor unit and/
or the service panel in the outdoor unit are not
attached securely, it could result in a fire or an
electric shock due to dust, water, etc.
I Be sure to use the part provided or specified
parts for the installation work.
The use of defective parts could cause an injury
or leakage of water due to a fire, an electric shock,
the unit falling, etc.
I Be sure to cut off the main power in case of
setting up the indoor electronic control P.C.
board or wiring works.
It could cause an electric shock.
I The appliance shall be installed in accordance
with national wiring regulations.
Caution
I Perform the drainage/piping work securely
according to the installation manual.
If there is a defect in the drainage/piping work,
water could drop from the unit and household
goods could be wet and damaged.
I Fasten a flare nut with a torque wrench as
specified in this manual.
When fastened too tight, a flare nut may broken
after a long period and cause a leakage of re-
frigerant.
2. SELECTING THE INSTALLATION LOCATION
2-1 INDOOR UNIT
• Where airflow is not blocked.
• Where cool air spreads over the entire room.
• Maximum refrigerant piping length between indoor unit and outdoor unit is 25 m and the difference of height
of both units is 10 m.
• Rigid wall or ceiling without vibration.
• Where it is not exposed to direct sunshine.
• Where easily drained.
• At a distance 1 m or more away from your TV and radio. Operation of the air conditioner interferes with radio
or TV reception in areas where reception is weak. An amplifier may be required for the affected device.
• In a distance as far as possible from fluorescent and incandescent lights (so the infrared remote control can
operate the air conditioner normally).
• Where the air filter can be removed and replaced easily.
2-2 WIRELESS REMOTE CONTROLLER MOUNTING
• Place of mounting
- Where it is easy to operate and easily visible.
- Where children cannot touch.
• Mounting
Select a position about 1.2 m above the floor, check that signals from the controller are surely received by
the indoor unit from that position ('beep' or 'beep-beep' receiving tone sounds), attach remote controller
holder 4 to a pillar or wall, then set the wireless remote controller 3.
In rooms where inverter type fluorescent lamps are used, the signal from the wireless remote controller may
not be received.
2-3

OUTDOOR UNIT

• Where it is not exposed to strong wind.
• Where airflow is good and dustless.
• Where it is not exposed to rain and direct sunshine.
• Where neighbours are not annoyed by operation sound or hot air.
• Where rigid wall or support is available to prevent the increase
of operational sound or vibration.
• Where there is no risk of combustible gas leakage.
• When installing the unit at a high level, be sure to fix the unit legs.
• Where it is at least 3 m away from the antenna of TV set or
radio. Operation of the air conditioner interferes with radio or
TV reception in areas where reception is weak. An amplifier
may be required for the affected device.
• Install the unit horizontally.
Note:
It is advisable to make a piping loop near outdoor unit so as to reduce vibration transmitted from there.
Caution:
Avoid the following places for installation where air conditioner trouble is liable to occur.
• Where flammable gas could leak.
• Where there is much machine oil.
• Salty places such as the seaside.
• Where sulfide gas is generated such as a hot spring.
• Where there is high-frequency or wireless equipment.
