6. Test run
 U1, K1, T1, F1 Type
6-2. Caution
This unit may be used in a single-type refrigerant system where 1 outdoor unit is connected to 1 indoor unit.
The indoor and outdoor unit control PCBs utilize a semiconductor memory element (EEPROM). The settings
required for operation were made at the time of shipment.
Only the correct combination of indoor and outdoor units can be used.
This test run manual describes primarily the procedure when using the wired remote controller.
6-3. Test Run Procedure
Recheck the items (see IV-4) to che ck before the test run.
Turn ON the indoor and outdoor power.
Set the remote controller to “test run.”
Return the remote controller to normal
control.YESNO Automatic
address?(See I-98)
(See 6-4) Check the combination (wiring) of indoor and
outdoor units.
Refer to “Table of  Self-Diagnostic
Functions and Corrections” to 
check the system. YESNO
Note:   Check the indoor-side drainage. Has the
test run been
completed?Check the warning code.

6-4. Items to Check Before the Test Run
(1)
(2)Turn the breaker ON at least 12 hours in advance in order to energize the crank case heater.
Fully open the closed valves on the liquid tube and gas tube sides.
6-5. Test Run Using the Remote Controller
(1) Press and hold the remote controller  button for 4 seconds or longer. Then press the  button.
• “TEST” appears in the LCD display during the test run.
 Temperature control is not possible when test run mode is engaged.
(This mode places a large load on the devices. Use it only when performing the test run.)
(2)
Note: The outdoor unit will not operate for approximately 3 minutes after the power is turned ON or after it stops
operating.
(3)
Refer to the “Table of Self-Diagnostic Functions and Corrections” on the next page, and correct the problem.
(4)
 button again. Check that “TEST” disappears from the LCD display.
(This remote controller includes a function that cancels test run mode after 60 minutes have elapsed, in order to
prevent continuous test run operation.)
(5)Use either Heating or Cooling mode to perform the test run.
If normal operation is not possible, a code appears on the remote controller LCD display.
After the test run is completed, press the 
For the test run of an inverter outdoor unit, operate the compressors for a minimum of 10 minutes.
* When performing a test run using a wired remote controller, 
operation is possible without attaching the cassette-type 
ceiling panel. 
(“P09” will not be displayed.)
6-6. Precautions
Request that the customer be present when the test run is performed. At this time, explain the operation manual
and have the customer perform the actual steps.
Be sure to pass the manuals and warranty certificate to the customer.
Check that the AC 230 / 208 V power is not connected to the inter-unit control wiring connector terminal.
* If AC 230 / 208 V is accidentally applied, the indoor or outdoor unit control PCB fuse (0.5A for both indoor
and outdoor units) will blow in order to protect the PCB. Correct the wiring connections, then disconnect the
2P connectors (indoor: blue, OC) (outdoor: blue, OC) that are connected to the PCB, and replace them with
2P connectors (indoor: brown, EMG) (outdoor: brown, EMG). (Refer to the figure below.) If operation is still not
possible after changing the brown connectors, try cutting the varistor (VA002) (both indoor and outdoor).
(Be sure to turn the power OFF before performing this work.)

A maximum of 8 indoor units can be connected to 1 remote controller.
Set the system address (refrigerant tubing system address) before turning on the remote power switch.
(Refer to “Setting the system addresses” on next page.)
(Set using the system address rotary switch on the outdoor unit control PCB.)
(Wiring procedure)
(1) Connect the remote controller to the indoor unit remote
controller wiring.
Use the remote controller connection wire coming from
the indoor unit, and field-supply wire and a wire joint to
complete the connection as shown in Fig. 6-6b. The
remote controller connection wire coming from the
indoor unit includes a connector, therefore cut off the
connector and use the wire joint to connect the wire
from the remote controller.
(2) Connect the indoor units (U1, U2) and the outdoor units
(1, 2).
Connect the other outdoor units and indoor units (with
different refrigerant systems) in the same way.
Connect the inter-unit control wiring to the indoor units
(U1, U2) for each refrigerant system.

Automatic address setting using the remote controller
When the outdoor unit shown in “Basic wiring diagram 2” is used for group control of multiple outdoor units , use the
remote controller to perform automatic address setting. (During automatic address setting, “SETTING” blinks on the
remote controller display.)
Press the remote controller timer time   button and 
 button simultaneously. (Hold for 4 seconds or longer.)
Then press the 
 button. (Item code “AA” appears: All systems automatic address setting.)
(Automatic address setting is performed in sequence for all outdoor units from No. 1 to No. 30. When automatic
address setting is completed, the units return to normal stopped status.)
To select each refrigerant system individually and perform automatic address setting, press the remote controller
timer time   button and 
 button simultaneously. (Hold for 4 seconds or longer.) Then press either the tempera-
ture setting   or 
 button. (Item code “A1” appears: Individual system automatic address setting)
Use either the 
 or  button to select the outdoor unit to perform automatic address setting. (For example,
when selected R.C.1 “R.C.1” is displayed.) Then press the 
 button. (Automatic address setting is performed for
refrigerant circuit 1.) When automatic address setting for circuit 1 is completed, the system returns to normal
stopped status. When automatic address setting for circuit 1 is completed, the system returns to normal stopped
status. In the same way, press the remote controller timer time   button and 
 button simultaneously to per-
form automatic address setting for a different R.C. (refrigerant circuit) if necessary. Then in the same way as
above (use the 
 button to display “R.C.2,” for example), select the next circuit and perform automatic ad-
dress setting.

6. Test run
Indicating (marking) the indoor and outdoor unit combination number
Indicate (mark) the number after automatic address setting is completed.
(1) So that the combination of each indoor unit can be easily checked when multiple units are installed, ensure that
the indoor and outdoor unit numbers correspond to the system address number on the outdoor unit control PCB,
and use a magic marker or similar means which cannot be easily erased to indicate the numbers in an easily
visible location on the indoor units (near the indoor unit nameplates).
Example: (Outdoor) 1 - (Indoor) 1-1...(Outdoor) 2 - (Indoor) 2-2...
(2) These numbers will be needed for maintenance. Be sure to indicate them.
* Use the remote controller to check the addresses of the indoor units. Press and hold the 
 button and 
button for 4 seconds or longer (simple settings mode). Then press the button  and select the indoor
address. (Each time the button is pressed, the address changes as follows: 1-1, 2-1, ....) The indoor unit fan
operates only at the selected indoor unit. Confirm that correct fan is operating, and indicate address on the
indoor unit.
Press the 
 button again to return to the normal remote controller mode.
For details, refer to the separate handbook.
