the installation manuals enclosed with the air conditioner for details on wiring and installing the air conditioner unit.
To ensure safety, always read

1 Safety Precautions

• The following two symbols are used to denote dangers that may be caused by incorrect use and their degree:
This symbol denotes what could lead to serious injury or death if you misuse above remote controllers.
WARNING
This symbol denotes what could lead to a personal injury or damage to your property if you misuse above remote controllers.
CAUTION
• After reading this installation manual, keep it in a place where the final user can see it anytime he or she wants to it.
When someone moves, repairs or uses above remote controllers, make sure that this manual is forwarded to the final user.
Ask your dealer or technical representative to install the unit.
Any deficiency caused by your own installation may result in an electric
shock or fire.
Install in a place which is strong enough to withstand the weight
of above remote controllers.
Any lack of strength may cause above remote controllers to fall down,
resulting in personal injury.
Firmly connect the wiring using the specified cables. Carefully
check that the cables do not exert any force on the terminals.
Improper wiring connections may produce heat and possibly a fire.
Never modify or repair above remote controllers.
Any deficiency caused by your modification or repair may result in an
electric shock or fire.
Consult with your dealer about repairs.
Do not install in any place exposed to flammable gas leakage.
Flammable gases accumulated around the body of above remote
controllers may cause an explosion.
Do not use in any special environment.
Using in any place exposed to oil (including machine oil), steam and
sulfuric gas may deteriorate the performance significantly or give
damage to the component parts.
When installing the remote controller in a hospital or communication facility, take ample countermeasures against noise.
Inverters, emergency power supply generators, high-frequency medical equipment, and wireless communication equipment can cause the remote
controller to malfunction or to fail. Radiation from the remote controller may effect communication equipment and prevent medical operations on
the human body or interfere with image transmission and cause noise.
Wire so that it does not receive any tension.
Tension may cause wire breakage, heating or fire.
Completely seal the wire lead-in port with putty.
Any dew, moisture, insects entering the unit may cause an electric
shock or a malfunction.
Do not wash with water.
Doing so may cause an electric shock or a malfunction.
Do not install in any place at a temperature of more than 40
;
less than 0
or exposed to direct sunlight.
Doing so may cause deformation or a malfunction.
Do not install in any steamy place such a bathroom or kitchen.
Avoid any place where moisture is condensed into dew. Doing so may
cause an electric shock or a malfunction.

below before starting installation.
WARNING
Ensure that installation work is done correctly following this

installation manual.

Any deficiency caused by installation may result in an electric shock or
fire.
All electrical work must be performed by a licensed technician,
according to local regulations and the instructions given in this
manual.
Any lack of electric circuit or any deficiency caused by installation may
result in an electric shock or fire.
Do not move and re-install above remote controllers yourself.
Any deficiency caused by installation may result in an electric shock or
fire.
Ask your distributor or special vendor for moving and installation.
CAUTION
Do not install in any place where acidic or alkaline solution or
special spray are often used.
Doing so may cause an electric shock or malfunction.
Use standard wires in compliance with the current capacity.
A failure to this may result in an electric leakage, heating or fire.
Do not touch any PCB (Printed Circuit Board) with your hands or
with tools. Do not allow dust to collect on the PCB.
Doing so may cause fire or an electric shock.
Do not remove the insulation sheet on the PCB.
Doing so may cause an electric shock.
Do not touch any control button with your wet hands.
Doing so may cause an electric shock or a malfunction.
;
or
Do not press any control button using a sharp object.
Doing so may cause an electric shock or a malfunction.
Never apply 100VAC or 200VAC. The maximum voltage that can
be applied on this unit is 30VDC.
Applying an excessive voltage may cause damage, igniting or fires.
