INSTALLATION MANUAL

HFC

utilized

R410A

When installing an MXZ series 
outdoor unit, refer to the MS 
and MSH type manual for 
indoor unit set up.

WARNING

Q

  Do not install the unit by yourself (customer).

Incomplete installation could cause injury due to fi re, electric shock, the unit 
falling or leakage of water. Consult the dealer from whom you purchased the 
unit or special installer.

Q

  Install the unit securely in a place which can bear the weight of the 

unit.

When installed in an insuffi cient strong place, the unit could fall causing 
injury.

Q

  Use the specifi ed wires to connect the indoor and outdoor units securely 

and attach the wires fi rmly to the terminal block connecting sections so 
the stress of the wires is not applied to the sections.

Incomplete connecting and fi xing could cause fi re.

Q

  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 fi re or an electric shock due to defective contact, defective 
insulation, exceeding the permissible current, etc.

Q

  Check that the refrigerant gas do not leak after installation has 

completed.

 

If refrigerant gas leaks indoors, and comes into contact with the fi re of a fan 
heater, space heater, stove, etc., harmful substances will be generated.

Q

  Perform the installation securely referring to the installation manual.

 

Incomplete installation could cause a personal injury due to fi re, electric shock, 
the unit falling or leakage of water.

Q

  Perform electrical work according to the installation manual and be sure 

to use an exclusive circuit.

If the capacity of the power circuit is insuffi cient or there is incomplete electrical 
work, it could result in a fi re or an electric shock.

Q

  Attach the electrical cover to the indoor unit and the service panel to the 

outdoor unit securely.

If the electrical cover in the indoor unit and/or the service panel in the outdoor 
unit are not attached securely, it could result in a fi re or an electric shock due 
to dust, water, etc.

Q

  Be sure to use the part provided or specifi ed parts for the installation 

work.

The use of defective parts could cause an injury or leakage of water due to a 
fi re, an electric shock, the unit falling, etc.

Q

  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.

Q

  The appliance shall be installed in accordance with national wiring 

regulations.

Q

  When installing or relocating the unit, make sure that no substance other 

than the specifi ed refrigerant (R410A) enters the refrigerant circuit.

 

Any presence of foreign substance such as air can cause abnormal pressure 
rise or an explosion.

1.  THE FOLLOWING SHOULD ALWAYS BE 

OBSERVED FOR SAFETY

  Be sure to read “THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR 

SAFETY” before installing the air conditioner.

  Be sure to observe the cautions specifi ed 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 OPERATING 

INSTRUCTIONS in a handy place on the customer’s site.

CAUTION

Q

  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.

Q

  Do not install the unit in a place where an infl ammable gas leaks.

 

If gas leaks and accumulates in the area surrounding the unit, it could cause 
an explosion.

Q

  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.

Q

  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.

Q

 Fasten a fl are nut with a torque wrench as specifi ed in this manual.

 

When fastened too tight, a fl are nut may broken after a long period and cause 
a leakage of refrigerant.

CAUTION

Avoid the following places for installation where air conditioner trouble is liable to 
occur.

 Where fl ammable gas could leak.

  Where there is much machine oil.

  Salty places such as the seaside.

 Where sulfi de gas is generated such as a hot spring.

  Where there is high-frequency or wireless equipment.

In rooms where inverter type fl uorescent lamps are used, the signal from the wireless 
remote controller may not be received.

2-3  WIRELESS REMOTE CONTROLLER MOUNTING

  Place of mounting

•  Where it is easy to operate and easily visible.
•  Where children can not touch.

 Mounting

 

Select a position about 1.2 m above the fl oor, check that signals from the remote 
controller are surely received by the indoor unit from that position (‘beep’ or ‘beep-
beep’ receiving tone sounds). After that, attach remote controller holder 

3

 to a 

pillar or wall and set the wireless remote controller 

6

.

2.  SELECTING THE INSTALLATION LOCATION

2-1 INDOOR UNIT

 Where airfl ow is not blocked.

  Where cool air spreads over the entire room.

  Maximum refrigerant piping length between indoor unit and outdoor unit is 25 m 

(for 60 type) and 30 m (for 71/80 type) and the difference of height of both units is 
10 m (for 60 type) and 15 m (for 71/80 type).

  Rigid wall 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 

amplifi er may be required for the affected device.

  In a place as far away as possible from fl uorescent and incandescent lights (so the 

infrared remote control can operate the air conditioner normally).

  Where the air fi lter can be removed and replaced easily.

2-2 OUTDOOR UNIT

  Where it is not exposed to strong wind.

 Where airfl ow 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 fi x the unit legs.

  Where it is at least 3 m away from the antenna of TV set or radio. Operation of the 

air conditioner may interfere with radio or TV reception in areas where reception is 
weak. An amplifi er may be required for the affected device.

  Install the unit horizontally.

  Please install it in an area not affected by snowfall or blowing snow. In areas with 

heavy snow, please install a canopy, a pedestal and/or some baffl e boards.

Note:

It is advisable to make a piping loop near outdoor unit so as to reduce vibration 
transmitted from there.
