PACKAGED AIR CONDITIONER

1) Turn off the the power.

Be sure to turn off the power before attempting to repair the

unit such as the disassembly of the unit.

2) Be careful of electric shock

When checking the circuit with the power connected in

unavoidable circumstances, take special care not to touch the

live parts. There is a danger of electric shock.

3) Use of appropriate parts

Be sure to use the genuine parts of the relevant model when

it is necessary to replace parts. (Replace parts instead of

repairing with regard to the malfunctioning of electric contact

areas. Never attempt to modify the unit. It is extremely dan-

gerous for the consumer to attempt to repair the unit on

his(her) own.)

4) Use of proper tools

Use appropriate tools for repair, and use measuring equip-

ment after accurate calibration. Using worn tools may result

in problems, including poor contact and poor connection.

5) Avoid damage to electric wire or electric cord.

Check the electric cord or electric wire for any damage during

repair.

Be sure to replace it if damaged.

6) Avoid intermediate connection of the electric cord.

Never attempt to make an intermediate connection by cutting

the middle area of the electric cord or make a connection to

the power receptacle as it is very dangerous, causing prob-

lems or fire.

7) Checking of insulation

Be sure to check the insulation resistance after completion of

the assembly work.

(Check whether the insulation resistance of the electric wire

and grounding terminal is over 30MΩby using the insulation

resistance tester, and then connect the power source.)

8) Checking of grounding

Check the grounding condition, and perform repair if poorly

grounded.

9) Checking of installation condition

Check the installation condition of the unit, and perform

repair if there is any defective area.

If the unit remains in an unstable installing condition, install

it at a new site.

10) Be careful of children

As the repair of the unit involves a lot of dangerous elements,

do not allow children to approach nearby during repair work.

3-3 Check and Test Operation

•Be sure to check the following again after completion of installation.

•After checking, read the owner's instructions carefully, and perform a test operation.

Then deliver the unit to the customer.

(When delivering the unit, be sure to read carefully and follow the contents of the owner's

instructions.)

3-2-4(b) Test Operation

1. Be sure to check whether the service valve is opened before attempting to

perform the test operation.

2. Never attempt to start test operation by force pressing the electronic contactor

as it is very dangerous.

(This is very dangerous as the protective device does not work.)

3. Be sure to perform the test operation after installment.

It is easy to start the test operation in winter if you increase the sensor

temperature to 23°C ~25°C by holding the indoor temperature sensor (Cooling

operation)
