After completing the additional refrigerant charging, record the charging
amount on the accessory “REQUEST FOR THE INDICATON” label
(Installation records) and adhere it to the back side of the front panel.
11-2-2 Procedure of check operation
• Check operation perform the following work. Do the check operation
following below.
Otherwise, malfunction code “U3” will be displayed in the remote
controller and nomal operation can not be carried out.
Check of shutoff valve opening
Check of miswiring
Judgment of piping length
Check of refrigerant overcharge
NOTE
• Check operation can not carried out at outdoor temp. less than 23°F.
Perform the check operation at day or time that outdoor temp. is 23°F
or more.
[Check Operation Procedure]
(1) Close the EL. COMPO. BOX lid and all front panels except as the
side of the EL. COMPO. BOX and turn on the power to the outside
unit and all connected BS, 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 31) 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 control-
ler displays malfunction code] and perform the check operation again.
(Refer to figure 31)

2. EL. COMPO.BOX (2) lid
3. [Service Precaution] label (upper)
4. [Service Precaution] label (lower)
NOTE
For interrupting the check operation, push RETURN button (BS3).
[Remote controller displays malfunction code]
NOTE
If any malfunction codes other than the above are displayed, check the
service manual for how to respond.
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 EL. CONPO. 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 EL. COMPO. 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 BS, 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 correspond-
ing 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 controller
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 com-
pressor, 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 out-
side 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.
Malfunc-
tion code
Installation error Remedial action
E3, E4
F3, F6
UF
The shutoff valve of the outside
unit is left closed.
Open the shutoff valve.
U1
The phases of the power to
the outside unit is reversed.
Exchange two of the three phases (L1,
L2, L3) to make a proper connection.
U1
U4
LC
No power is supplied to an
outside, BS or indoor unit
(including phase interruption).
Make sure the power source wire is
properly connected to the outside, BS or
indoor unit and revise if necessary.
UF
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.
E3
F6
UF
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.
E4
F3
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.
U7, U4
UF, UH
Field wiring is connected to "TO
MULTI UNIT (Q1,Q2)" terminal
on the outside unit PC-board
(A1P) when the system is one
outdoor system.
Remove the line from the “TO MULTI UNIT
(Q1, Q2)” terminal.
