When the air conditioning unit has stopped, check on an indoor
unit if the second code No. of mode No. 21 is set to "02".
If the air conditioning unit does not stop operating or the second
code No. is not "02", repeat step 4.
If the outdoor unit is not turned on, the display on the remote
controller will show "
U4
" or "
UH
" (refer to
). However, you can continue setting this function
because these messages are only applicable to outdoor units.
After setting this function, be sure to turn on the outdoor unit
before performing the test operation on the outdoor unit.
If any other error display occurs on the display of the remote
controller, refer to
and the operation
manual of the outdoor unit. Check the defective point.
Using the remote controller
Check on an indoor unit if the second code of mode No. 21 is set to
"01" (= factory setting). Change the second code according to the
external static pressure of the duct to be connected as shown in
table 2.
Table 2
Setting air filter sign
Remote controllers are equipped with liquid crystal air filter signs
to display the time to clean the air filter.
Change the Second code No. depending on the amount of dirt
or dust in the room. (Second code No. is factory set to "01" for
air filter contamination-light.)
Air filter contamination
Control by 2 Remote Controllers (Controlling 1 indoor
unit by 2 remote controllers)
When using 2 remote controllers, one must be set to "MAIN" and the
other to "SUB".
Test operation
Refer to the section of
"For the following items, take special care
during construction and check after installation is finished" on page 2
After finishing the construction of refrigerant piping, drain piping,
and electric wiring, conduct test operation accordingly to protect
the unit.
1
Open the gas side stop valve.
2
Open the liquid side stop valve.
3
Electrify crank case heater for 6 hours.
4
Set to cooling operation with the remote controller and start
operation by pushing ON/OFF button.
5
Press Inspection/Test Operation button 4 times and operate at
Test Operation mode for 3 minutes.
6
Press Inspection/Test Operation button and operate normally.

If there is no change after airflow adjustment in the
ventilation paths, be sure to perform setting the
automatic airflow adjustment again.
Contact your dealer if there is no change after
performing airflow adjustment in the ventilation paths,
after performing the test operation of the outdoor unit
or when the air conditioning unit is moved to another
location.
If booster fans, an outdoor air processing unit or HRV
via duct are used, do not use automatic airflow
adjustment control with a remote controller.
If the ventilation paths have been changed, perform
the setting of the airflow automatic adjustment again
as described above from step 3 onwards.
