Safety Precautions

• Before instralling this unit,make sure you read all the “Safety Precautions”.

• This manual describes the installation of LM-AP and wiring to the outdoor unit.

• Please look at the installation manual of an air-conditioning unit about the installation method of an air-conditioning unit.

• The “Safety Precautions” provide very important points regarding safety. Make sure you follow them.

Symbols and Terms

Statements identify condition or practices that could result in personal injury or loss of life.

Statements identify condition or practices that could result in damage to the unit or other

property.

Symbols used in the illustrations

: Indicates a part which must be grounded.

: Indicates that the main switch must be turned off before servicing.

(This symbol is displayed on the main unit label.) <Color: Blue>

: Beware of electric shock.(This symbol is displayed on the main unit label) <Color: Yellow>

: Please pay attention to electric shock fully because this is not Safety Extra Low-Voltage (SELV)

circuit.

And at servicing,please shut down the power supply for LM-AP.

WARNING

CAUTION

Ask your dealer or technical representative to install.

Any deficiency cased by your own installation may result in an

electric shock and fire.

Ensure that installation work is done correctly following

that installation manual.

Any deficiency caused by installation may result in an electric

shock or fire.

Install in a plase which is strong enough to withstand the

weight of the unit

Any lack of the strength may cause the unit to fall down,

resulting in a personal injury.

Any deficiency caused by installation may result in an electric

shock, fire or incorrect operation.

All electrical work must be performed by a licenced

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.

Wire and connect using the desired cables securely so

that any external force from the cable is imparted to the

terminal connections.

Imperfect connection and fixed may result in heading or fire.

Securely install the cover (panel) of the LM-AP.

If the cover (panel) is not installed properly, dust or water may

enter the unit and fire or electric shock may result.

Never modify or repair the unit by yourself.

Any deficiency caused by your modification or repair may

result in an electric shock or fire. Consult with your distributor

for repair.

Do not move and re-install the unit yourself.

Any deficiency caused by installation may result in an electric

shock or fire. Ask your distributor or special vender for moving

and installation.

Make sure that the unit is powered by dedicated line.

Other appearance connected to the same line could cause an

overload.

Make sure that there is a main power switch.

A ready accessible breaker for power source line helps

reduce the risk of electric shocks.Installation of a breaker is

mandatory in same areas.

If it is assumed that moisture advances into the unit,

such as the time of rainy weather, do not do check or

work of an electric circuit.

It may become the cause of damage of a fire and the unit by

an electric shock or corrosion.

• 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 the LM-AP, make sure that this manual is forwarded to the final user.

CAUTION

Do not install the unit where combustible gas may leak.

If the gas leaks and accumulates around the unit, an

explosion may result.

Do not use in any special environment.

Using in any place exposed to oil(including machine oil),

steam and sulfuric gas may deteriorate the performances

significantly or given damage to the component parts.

When installing the unit in a hospital, communication

station, or similar place, provide sufficient protection

against noise.

The inverter equipment, private power generator, high-

frequency medical equipment, or radio communication

equipment may cause the air conditioner to operate

erroneously, or fail to operate. On the other hand, the air

conditioner may affect such equipment by creating noise that

disturbs medical treatment or image broadcasting.

Do not wash with water.

Doing so may cause an electric shock or a malfunction.

Do not install in any steamy place such as bath room or

kitchen.

Avoid any place where moisture is condensed into dew.

Doing so may cause an electric shock or a malfunction.

Do not touch any PCB(Printed Circuit Board) with your

hand or tools. Do not have dust collected on the PCB.

Doing so may cause an electric shock or fire.

Do not install in any place where acidic or alkaline

solution or special spray are other be used.

Doing so may cause an electric shock or a malfuction.

Do not install in any place at a temperature of more then

43 ˚C or less than -15˚C.

It may become the cause of modification and failure.

Safety dispose of the packing materials.

Tear apart and throw away plastic packaging bags so that

children will not play with them. If children play with a plastic

bag which was not torn apart, they face the risk of suffocation.

Be sure to shut off the power source of the unit and all

the other unit to connected to the unit before wiring.

Doing so may cause an electric shock or a malfunction.

Use only an earth leakage breaker and fuse of the

specified capacity.

If no earth leakage breaker is installed, it may cause an

electric shock.

Using fuse and wire or copper wire with too large capacity

may cause a malfunction of unit or fire.

A power-supply line and a transmission line do not band

together, or are not contained in the same metal pipe.

Doing so may cause a malfunction of unit.

This appliance must be earthed.

Make sure to install a protective earth(PE) line. Do not

connect the protective earth line to gas or water pipes,

lightning conductors or telephone grounding lines. Improper

grounding may cause an electric shock.

Wire so that it dose not received any tension.

Tension may caused wire breakage, heating or fire.

Use standard wires in compliance with the current

capacity.

A failure to this may result in an electric leakage, heating or

fire.

Never connect the power source to the transmission line.

Doing so may caused a malfunction or a failture.

Do not touch the switches with wet fingers.

Touching a switch with wet fingers can cause electric shock.

3-3 Connection Methods

Use wire clamps provided to secure the wires and prevent external force from being conveyed by the wire to

the wire connections.

* External force could cause deformation or damage to the terminal blocks.

Use a small screwdriver to connect diameter 0.2 to 2.5 mm2(AWG24 to 12) cable for

terminal block (TB21) on the unit. Tightening torque is 0.5 to 0.6 Nm. Up to two wires can

be connected to one terminal block.
