INSTALLATION MANUAL
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 leak and accumulate 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
‘beepbeep’ 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 and
the difference of height of both units is 10 m.
•
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 interferes 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.
