1 . Safety precautions

This installation manual describes the installation methods and precautions related to the remote control. Use this
manual together with the user’s manuals for the indoor unit, outdoor unit and other option equipment. Please read
this manual carefully before starting the installation work to install the unit properly.

Safety precautions

●

Please read this manual carefully before starting installation work to install the unit properly.

Every one of the followings is important information to be observed strictly.

WARNING

CAUTION

It could have serious consequences depending on the circumstances.

●

The following pictograms are used in the text.

Never do. Always follow the instructions given.

●

Keep this manual at a safe place where you can consult with whenever necessary. Show this manual to installers

when moving or repairing the unit. When the ownership of the unit is transferred, the “Installation Manual”
should be given to a new owner.

Failure to follow these instructions properly may result in serious consequences such as
death, severe injury, etc..

Failure to follow these instructions properly may cause injury or property damage.

WARNING

Ask a professional contractor to carry out installation work according to the installation manual.

Improper installation work may result in electric shocks, fire or break-down.

Shut OFF the main power source before starting electrical work.

Otherwise, it could result in electric shocks, break-down or malfunction.

Do not install the unit in appropriate environment or where inflammable gas could generate, flow
in, accumulate or leak.

If the unit is used at places where air contains dense oil mist, steam, organic solvent vapor, corrosive
gas (ammonium, sulfuric compound, acid, etc) or where acidic or alkaline solution, special spray, etc.
are used, it could cause electric shocks, break-down, smoke or fire as a result of significant
deterioration of its performance or corrosion.

Do not install the unit where water vapor is generated excessively or condensation occurs.

It could cause electric shocks, fire or break-down.

Use the specified cables for wiring, and connect them securely with care to protect electronic
parts from external forces.

Improper connections or fixing could cause heat generation, fire, etc.

Seal the inlet hole for remote control cable with putty.

If dew, water, insect, etc. enters through the hole, it could cause electric shocks, fire or break-down.

When installing the unit at a hospital, telecommunication facility, etc., take measures to suppress
electric noises.

It could cause malfunction or break-down due to hazardous effects on the inverter, private power
generator, high frequency medical equipment, radio communication equipment, etc.
The influences transmitted from the remote control to medical or communication equipment could
disrupt medical activities, video broadcasting or cause noise interference.

CAUTION

Do not install the remote control at following places.

It could cause break-down or deformation of remote control.
(1) Where it is exposed to direct sunlight
(2) Near the equipment to generate heat
(3) Where the surface is not flat

Do not leave the remote control with its upper case removed.

When the upper case is removed, put it in a packing box or packing bag to protect internal PCBs or
other parts from dust, moisture, etc.

Cautions for selecting installation place

(1) Installation surface must be flat and sufficiently strong.

R/C case must not be deformed.

(2) Where the R/C can detect room temperatures accurately.

This is a must when detecting room temperatures with
the temperature sensor of R/C.

· Install the R/C where it can detect the average tempera­ture in the room.

· Install the R/C separated from a heat source sufficiently.

· Install the R/C where it will not be influenced by the
turbulence of air when the door is opened or closed.

Select a place where the R/C is not exposed to direct
sunlight or blown by winds from the air- conditioner or
temperatures on the wall surface will not deviate largely
from actual room temperature.

Request

Be sure not to install R/C at a place where temperatures around the installation surface of R/C may differ largely from
actual room temperature.
Difference between detected temperature and actual room temperature could cause troubles.
The correction for detected temperature by the R/C cannot offset such temperature difference because it corrects the
detected temperatures itself.

Request

Do not install the R/C at a place where it is exposed to direct sunlight or where surrounding air temperature exceeds 40°C
or drops below 0°C.
It could cause discoloration, deformation, malfunction or breakdown.
