WARNING

Safety precautions

①

Accessories

●P

lease 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 Failure to follow these instructions properly may result in serious consequences

such as death, severe injury, etc.

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

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, this manual should be given to a new owner.

●

Consult your dealer or a professional contractor to install the unit.

Improper installation made on your own may cause electric shocks, ﬁre or dropping of the unit.

●

Installation work should be performed properly according to this installation manual.

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

●

Be sure to use accessories and

speciﬁed

parts for installation work.

Use of unspeci

ﬁed parts may result in drop, ﬁre or electric shocks.

●

Install the unit properly to a place with

sufﬁcient

strength to hold the weight.

If the place is not strong enough, the unit may drop and cause injury.

●

Be sure to have the electrical wiring work done by

qualiﬁed

electrical installer, and use exclusive circuit.

Power source with insufﬁcient and improper work can cause electric shock and ﬁre.

●

Shut OFF the main power source before starting electrical work.

Otherwise, it could result in electric

shocks, break-down or malfunction.

●

Do not modify the unit.

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

●

Be sure to turn OFF the power circuit breaker before repairing/inspecting the unit.

Repairing/inspecting the unit with the power circuit breaker turned ON could cause electric shocks or injury.

●

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 dete

rioration 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.

●

Do not use the unit in a place where it gets wet, such as laundry room.

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

●

Do not operate the unit with wet hands.

It could cause electric shocks.

●

Do not wash the unit with water.

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 connec

tions or ﬁxing could cause heat generation, ﬁre, etc.

●

When installing the unit at a hospital, telecommunication facility, etc., take

measures to suppress electric noises.

It could cause malfunction or brea

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.

●

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

If dew, water

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

CAUTION

Please make sure that you have all of the following accessories.

Setting on site

PCB on the receiver has the

following switches to set the function.

Default setting is shown with

mark.

Up to two receiver or wired remote

control can be installed in one

indoor unit group.

When two receiver or wired remote

control are used, it is necessary

to change SW on the PCB to set it

as slave.

How to install the receiver

③

How to install the receiver(continued)

The following two methods can be used to install the receiver onto a ceiling or a wall.

Select a method according to the installation position.

<Installation position>

(A) Direct installation onto the ceiling with wood screws.

(B) Installation with accessory's bracket

⑤

Take out the connector to the backside from the hole of the lower case putting through the wiring at

①

⑥

Fit the upper case and the lower case, and tighten the screws.

Use this method when installaing onto a gypsum board (7 to 18mm), etc.

①

Catch the two protrusion of the enclosed bracket onto the

ﬁ

tting as shown above, and temporarily

ﬁ

with the screws. (The bracket has an Upper/Lower and front/back orientation. Con

ﬁ

rm the Upper/Lower

protrusion positions and the positional relation of the ø10 holes on the bracket and the installation hole

on the lower case with the above drawing.)

②

Insert the end of the installation

ﬁ

tting into the back of the ceiling from the opening, and tighten the

screws to

ﬁ

x the bracket onto the ceiling.

③

Pass the wiring from the rear side through the hole on the lower case.

④

Fit the lower case onto the bracket, and

ﬁ

x the lower case to the bracket using the two installation holes

shown above. (The other four holes are not used.)

for (A) to complete the installation.

Caution

Do not connect the wiring to the power source of the

terminal block. If it is connected, printed board will be

damaged.

Drill the receiver installation holes with

the dimensions shown right at the ceiling

position where wires can be connected.

Put through the wiring from the back side to the hole

of the lower case.

②

Fit the lower case into the ceiling opening. Make

sure that the clearance between the convex part of

the back of the lower case and the ceiling opening

must be as equal as possible on both sides.
