• Please report to or take consent by the supply authority before connection
to the 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.
Symbols put on the unit
: Indicates an action that must be avoided.
: Indicates that important instructions must be followed.
: Indicates a part which must be grounded.
: Indicates that caution should be taken with rotating parts.
: Indicates that the main switch must be turned off before servicing.
: Beware of electric shock.
: Beware of hot surface.
Warning:
Carefully read the labels affixed to the main unit.
Warning:
• Do not use refrigerant other than the type indicated in the manuals provided
with the unit and on the nameplate.
-
Doing so may cause the unit or pipes to burst, or result in explosion or fire during
use, during repair, or at the time of disposal of the unit.
- It may also be in violation of applicable laws.
- MITSUBISHI ELECTRIC CORPORATION cannot be held responsible for
malfunctions or accidents resulting from the use of the wrong type of refrigerant.
• 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
purchased the unit or special installer.
• This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience
and knowledge, unless they have been given supervision or instruction
concerning use of the appliance by a person responsible for their safety.
• This appliance is intended to be used by expert or trained users in shops,
in light industry and on farms, or for commercial use by lay persons.
• 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 injured.
• Use the specified wires to connect the indoor and outdoor units securely
and attach the wires firmly to the terminal board connecting sections so the
stress of the wires is not applied to the sections.
Incomplete connecting and fixing could cause fire.
• 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.
• Check that the refrigerant gas does not leak after installation has completed.
• 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.
• Perform electrical work according to the installation manual and be sure to
use an exclusive 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.
• If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.
• 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.
• 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.
• Ventilate the room if refrigerant leaks during operation.
If the refrigerant comes in contact with a flame, poisonous gases will be released.
• Children should be supervised to ensure that they do not play with the appliance.
• The installer and system specialist shall secure safety against leakage
according to local regulation or standards.
- Following standards may be applicable if local regulation are not available.
• Pay a special attention to the place, such as a basement, etc. where
refrigeration gas can stay, since refrigeration is heavier than the air.
Caution:
• Perform grounding.
Do not connect the ground wire to a gas pipe, water pipe arrester or
telephone ground wire. Defective grounding could cause an electric shock.
• Do not install the unit in a place where an inflammable gas leaks.
If gas leaks and accumulates in the area surrounding the unit, it could
cause an explosion.
• Install a ground leakage breaker depending on the installation place (where
it is humid).
If a ground leakage breaker is not installed, it could cause an electric shock.
• 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.
• 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 refrigerant.
2. Selecting the installation location
2.1. Indoor unit
• Where airflow is not blocked.
• Where cool air spreads over the entire room.
• Where it is not exposed to direct sunshine.
• At a distance 1 m or more away from your TV and radio (to prevent picture from
being distorted or noise from being generated).
• In a place as far away 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.
• Indoor units must be installed in a ceiling with a minimum height of 2.5 meters.
Warning:
Mount the indoor unit into a ceiling strong enough to withstand the weight of
the unit.
Note:
The phrase “Wired remote controller” in this installation manual refers only to the PAR-21MAA. If you need any information for THE PAR-31MAA, please refer to
either the installation manual or initial setting manual which are included in PAR-31MAA box.

1. Safety precautions
2.2. 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 operation
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. (Otherwise,
images would be disturbed or noise would be generated.)
• Install the unit horizontally.
Caution:
Avoid the following places for installation where air conditioner trouble is
