Use the specied refrigerant only

Never use any refrigerant other than that specified.

Doing so may cause a burst, an explosion, or fire when the unit is being used, serviced, or disposed of.

Correct refrigerant is specified in the manuals and on the spec labels provided with our products.

We will not be held responsible for mechanical failure, system malfunction, unit breakdown or accidents caused by failure to

follow the instructions.

Prepare the proper tools.

Prepare the proper protectors.

Provide adequate ventilation.

After stopping the operation of the air conditioner, turn off the power-supply breaker and pull the power plug.

Discharge the capacitor before the work involving the electric parts.

Do not perform the work involving the electric parts with wet hands.

Do not pour water into the electric parts.

Do not touch the refrigerant.

Do not touch the hot or cold areas in the refrigeration cycle.

When the repair or the inspection of the circuit needs to be done without turning off the power, exercise great caution not to

touch the live parts.

WARNING

• When the refrigeration circuit has a leak, do not execute pump down with the compressor.

• When pumping down the refrigerant, stop the compressor before disconnecting the refrigerant pipes.

The compressor may burst if air etc. get into it.

• When opening or closing the valve below freezing temperatures, refrigerant may spurt out from the gap

between the valve stem and the valve body, resulting in injuries.

SAFETY PRECAUTION2

2-1. ALWAYS OBSERVE FOR SAFETY

Before obtaining access to terminal, all supply circuits must be disconnected.

2-2. CAUTIONS RELATED TO NEW REFRIGERANT

Cautions for units utilizing refrigerant R32

Preparation before the repair service.

• Prepare the proper tools.

• Prepare the proper protectors.

• Provide adequate ventilation.

• After stopping the operation of the air conditioner, turn off

the power-supply breaker.

• Discharge the condenser before the work involving the

electric parts.

Precautions during the repair service.

• Do not perform the work involving the electric parts

with wet hands.

• Do not pour water into the electric parts.

• Do not touch the refrigerant.

• Do not touch the hot or cold areas in the refrigerating cycle.

• When the repair or the inspection of the circuit needs to be

done without turning off the power, exercise great caution

not to touch the live parts.

• When opening or closing the valve below freezing

temperatures, refrigerant may spurt out from the valve gap,

resulting in injuries.

Use new refrigerant pipes.

In case of using the existing pipes for R22, be careful with

the following.

· Be sure to clean the pipes and make sure that the insides

of the pipes are clean.

· Change flare nut to the one provided with this product.

Use a newly flared pipe.

· Avoid using thin pipes.

Use a vacuum pump with a reverse flow check

valve.

Vacuum pump oil may flow back into refrigerant cycle and

that can cause deterioration of refrigerant oil, etc.

Make sure that the inside and outside of refrige-

rant piping is clean and it has no contaminants

such as sulfur, oxides, dirt, shaving particles, etc,

which are hazard to refrigerant cycle.

In addition, use pipes with specified thickness.

Contamination inside refrigerant piping can cause deterio-

ration of refrigerant oil, etc.

Store the piping indoors, and both ends of the

piping sealed until just before brazing.

(Leave elbow joints, etc. in their packaging.)

If dirt, dust or moisture enters into refrigerant cycle, that can

cause deterioration of refrigerant oil or malfunction of com-

pressor.

Handle tools with care.

If dirt, dust or moisture enters into refrigerant cycle, that can

cause deterioration of refrigerant oil or malfunction of com-

pressor.

Use the following tools specifically designed for

use with R32 refrigerant.

The following tools are necessary to use R32 refrigerant.

Flare tool

Electronic refrigerant

charging scale

Vacuum pump adaptor

Size adjustment gauge

Gauge manifold

Torque wrench

Gas leak detector

Charge hose

Tools for R32

MEANINGS OF SYMBOLS DISPLAYED ON THE UNIT

WARNING This mark is for R32 refrigerant only. Refrigerant type is written on nameplate of outdoor unit.

Read the OPERATION MANUAL carefully before operation.

Service personnel are required to carefully read the OPERATION MANUAL and INSTALLATION MANUAL before operation.

Further information is available in the OPERATION MANUAL, INSTALLATION MANUAL, and the like.

OBH790L

The refrigerant oil applied to flare and flange

connections must be ester oil, ether oil or

alkylbenzene oil in a small amount.

If large amount of mineral oil enters, that can cause deterio-

ration of refrigerant oil, etc.

Do not use refrigerant other than R32.

If other refrigerant (R22, etc.) is used, chlorine in refrige-

rant can cause deterioration of refrigerant oil, etc. Ventilate the room if refrigerant leaks during

operation. If refrigerant comes into contact with

a flame, poisonous gases will be released.

Never use any refrigerant other than that specified.

Doing so may cause a burst, an explosion, or fire when the

unit is being used, serviced, or disposed of.

Correct refrigerant is specified in the manuals and on the

spec labels provided with our products.

We will not be held responsible for mechanical failure,

system malfunction, unit breakdown or accidents caused

by failure to follow the instructions.

Use the specified refrigerant only.
