controller and the master unit (the indoor unit connected with wire controller directly), the others connect with the master

unit through 2 pieces of polar wire( 3 pieces for model AD12/18MS1ERA, AD12/18MS1ERA(D),AD24MS2ERA,

AD24MS2ERA(D) and the bridge CN22 CN23 on slave units PCB should be cut

off ).

B. One wire controller controls one indoor unit, and the indoor unit connects with the wire controller through 3 pieces of

polar wire.

C. Two wired controllers control one indoor unit. The wire controller connected with indoor unit is called master one, the

other is called slave one. Master wire controller and indoor unit; master and slave wire controllers are all connected

through 3 pieces of polar wire.

6. Communication wiring:

The wire controller is equipped with special communication wiring in the accessories. 3-core terminal (1-white 2-yellow 3-

red) is connected with the terminal A, B, C of wire controller respectively.

The communication wiring is 5 meter long; if the actual length is more than it, please distribute wiring according to below

table:

"HOT KEEP" function

Heating Mode

15

"HOT KEEP" is operated in the following cases.

When heating is started:

In order to prevent blowing out of cool wind, the indoor unit fan stopped according to the room temperature which heating

operation is started. Wait for approx. 2 to 3 minute, and the operation will be automatically changed to the ordinary heating

mode.

Defrosting operation (in the heating mode):

When it is liable to frost, the heating operation is stopped automatically for 5 to 12 minutes once per approx. one hour,

and defrosting is operated. After defrosting is completed, operation mode is automatically changed to ordinary heating

operation.

When the room thermostat is actuated:

When room temperature increases and room temperature controller actuates, the fan speed is automatically changed to

stop under low temperature condition of indoor heat exchanger. When room temperature decreases, air conditioner

automatically changes over to ordinary heating operation.

Heat pump type warming

With the heat pump type warming, the mechanism of heat pump that concentrate heat of outdoor air with the help of

refrigerant to warm the indoor space, is utilized.

Defrosting operation

When a room is warmed with a heat pump type air conditioner, frost accumulates on the heat exchanger of outdoor unit

along with the drop of indoor temperature. Since the accumulated frost reduces the effect of warming, it is necessery to

automatically switch the operation to the defrosting mode. During the defrosting operation, heating operation is interrupted.

Atmospheric temperature and warming capacity

Warming capacity of heat pump type air conditioner decreases along with the drop of outdoor temperature.

When the warming capacity is not sufficient, it is recommended to use another heating implement.

Period of warm-up

Since the heat pump type air conditioner employs a method to circulate warm winds to warm

the entire space of a room, it takes time before the room temperature rises.

It is recommendable to start the operation a little earlier in a very cold morning.

Warming operation

Points to observe

Turn off the power supply switch. Do not touch with wet hand. Do not use hot water or volatile liquid.

Cleaning the air filter

Do not dry the air filter with fire.

Do not run the air conditioner without the air filter.

Pre-Season Care

See that there are no obstacles blocking the air inlet and air outlet of both indoor and outdoor units.

Make sure that the air filter is not dirty.

Cut in the power supply switch 12 hours before starting run.

Post-Season Care

Operate the unit with FAN mode on a fair day for about half a day to dry the inside of the unit well.

Stop operation and turn off the power supply switch. Electric power is consumed even the air conditioner is in stop.

Clean the air filter and set it in the place.

Care and Cleaning of the unit

Clean with soft and dry cloth.

If it is very dirty, dissolve neutral detergent in the lukewarm water and make the cloth wet with the water. After wiping,

clean off the detergent using clean water.

1.Clean the air filter by lightly tapping it or with the cleaner. It is more effective to clean

the air filter with water.

If the air filter is very dirty, dissolve neutral detergent in the lukewarm water (approx. 30 C),

rinse the air filter in the water, and thoroughly wash the air filter off the detergent

in the plain water.

2.After drying the air filter, set it up on the air conditioner.

Do not open the inlet grill until fan stops completely.

Fan will continue rotating for a while by the law of inertia after operation is being stopped.

CAUTION

Care and Maintenance

Troubleshooting

17

The followings are not malfunction

Shuru

When the air conditioner is started, when the compressor starts or stops

during operation or when the air conditioner is stopped, it sometimes sounds

"shuru shuru" or "gobo gobo". It is the flowing sound of the refrigerant, and it

is not a trouble.

Water flowing sound is heard.

This is caused by heat expansion or contraction of plastics.Cracking sound is heard.

It smells. Air which blows out from the indoor unit sometimes smells. The smell results

from residents of tobacco smoke or cosmetics stuck inside of unit.

When the air conditioner is used at restaurant etc. where dense edible oil

fume is always exists, white fog sometimes blows out of air outlet during

operation. In this case consult sales dealer for cleaning the heat exchanger.

During operation, white fog comes out

of indoor unit.

Unit does

not start

Wait for

three

minutes

It is switched into the FAN mode during

cooling.

To prevent frost from being accumulated on the indoor unit heat exchanger,

it is sometimes automatically switched to the FAN mode,but it will soon return

to the cooling mode.

Even if the operation switch is turned on, cooling, dehumidifying or heating

is not operable for three minutes after the conditioner is stopped. Because

the protecting circuit is activated. (During this time air conditioner operates

in fan mode.)

The air conditioner can not be restarted

soon after it stops.

Air does not blow or the fan speed can

not be changed during dehumidifying.

During operation, operation mode has

changed over automatically.

Water or steam generates from the outdoor

unit during heating.

When it is excessively cooled during dehumidifying, the blower

automatically repeats reducing and lowering the fan speed.

Isn't the AUTO mode selected?

In the case of AUTO mode, operation mode is changed automatically from

cooling to heating or vise-versa according to the room temperature.

This results when frost accumulated on the outdoor unit is removed (during

defrosting operation).
