Installation of Outdoor Units 95

[Check Operation Procedure]

(1) Close the electrical components box lid and all front panels except

as the side of the electrical components box and turn on the power

to the outside unit and all connected Branch Selector, indoor units.

(Be sure to turn the power on at least 6 hours before operation in

order to have power running to the crank case heater.)

(2) Make the onsite settings as needed using the push button (BS1-

BS5) on the outside unit PC-board (A1P) with the power on. (See

“12 Onsite Settings”)

(3) Perform the check operation following the Check Operation Method

of the [Service Precautions] label (lower) on the EL. COMPO. BOX

lid. (See figure 32) The system operation for about 40~60 minutes

and automatically stops the check operation.

If the malfunction code is not displayed in the remote controller after

the system stop, check operation is completed. Normal operation

will be possible after 5 minutes. If the malfunction code is displayed

in the remote controller, correct the malfunction following [Remote

controller displays malfunction code] and perform the check opera-

tion again.

12. ONSITE SETTINGS

NOTE

In the case of a multi system, all onsite settings should be made on

the master unit. Settings made on sub units are invalid.

The outside unit to which the indoor unit transmission wire are con-

nected is the master unit, and all other units are sub units.

Use the push button switches (BS1 through BS5) on the outside unit

PC-board (A1P) to make the necessary onsite settings.

See the “Service Precautions” label (upper) on the Electrical compo-

nents box lid for details on the positions and operating method of the

push button switches and on the onsite setting.

Make sure to record the setting on the accessory “REQUEST FOR

THE INDICATION” label.

WARNING Electric Shock Warning

Use an insulated rod to operate the push buttons via the inspection

door of Electrical components box lid.

There is a risk of electric shock if you touch any live parts, since this

operation must be performed with the power on.

13. TEST RUN

13-1 Before test run

• Make sure the following works are completed in accordance with

the installation manual.

 Piping work

 Wiring work

 Air tight test

 Vacuum drying

 Additional refrigerant charge

 Check operation

• Check that all work for the Branch Selector, indoor unit are finished

and there are no danger to operate.

13-2 Test Run

After all works are completed, operate the unit normally and check the

following.

(1) Make sure the indoor and outside units are operating normally.

(2) Operate each indoor unit one by one and make sure the corre-

sponding outside unit is also operating.

(3) Check to see if cold (or hot) air is coming out from the indoor unit.

(4) Push the fan direction and strength buttons on the remote control-

ler to see if they operate properly.

NOTE

• Heating is not possible if the outdoor temperature is 75°F or

higher. Refer to the Operation manual.

• If a knocking sound can be heard in the liquid compression of the

compressor, stop the unit immediately and then energize the crank

case heater for a sufficient length of time before restarting the

operation.

• Once stopping, the compressor will not restart in about 5 minutes

even if the On/Off button of the remote controller is pushed.

• When the system operation is stopped by the remote controller,

the outside units may continue operating for further 5 minutes at

maximum.

• The outside unit fan may rotate at low speeds if the Night-time low

noise setting or the External low noise level setting is made, but

this is not a malfunction.

• If the check operation was not performed at first istallation, the

malfunction code “U3” will be displayed in the remote controller.

Perform the check operation following “11-2-2 Procedure of

Check Operation”.

indoor unit (including phase

interruption).

Make sure the power source wire is

properly connected to the outside ,

Branch Selector

or indoor unit and

revise if necessary.

There is conflict on the con-

nection of transmission wir-

ing in the system.

Check if the refrigerant piping line and

the transmission wiring are consistent

with each other.

Refrigerant overcharge.

Recalculate the additional amount refrig-

erant from the piping length and correct

the refrigerant charge level by recovering

any excessive refrigerant with a refriger-

ant recovery machine.

Insufficient refrigerant.

•

Check if the additional refrigerant

charge has been finished correctly.

•

Recalculate the additional amount

refrigerant from the piping length and

add the adequate amount.
