15.4. Precautions regarding test-runs

1

In order to detect stop valves failing to open, operation of the 
unit is compulsorily performed in cooling for 2-3 minutes during 
the first test run, even if the remote controller was set to heating 
operation. In this case, the remote controller will have kept 
displaying the heating symbol all the time and the unit will switch 
to heating operation automatically after elapse of that time.

2

In case you cannot operate the unit in test run mode for any 
unusual reason, refer to 

"15.5. Failure diagnosis at the moment 

of first installation" on page 19

.

3

In case of a wireless remote controller, execute the test run only 
after having installed the indoor unit decoration panel with infra-
red receiver first.

4

In case the panels of indoor units are not yet installed to the 
indoor units, make sure to shut off the power supply after 
finishing the complete test run.

5

A complete test run surely includes shutting off power after 
having performed a normal operation stop on the remote 
controller. Do not stop operation by turning circuit breakers off.

15.5. Failure diagnosis at the moment of first 

installation

If the malfunction code "

UA

" is displayed on the remote 

controller, there is a possibility that connection is with 
incompatible indoor unit.

In case nothing is displayed on the remote controller (the 
currently set temperature does not display), check for any of the 
following abnormalities before you can diagnose possible 
malfunction codes.

Disconnection or wiring error (between power supply and 
outdoor unit, between outdoor unit and indoor units, between 
indoor unit and remote controller).

The fuse on the outdoor unit PCB may have run out.

If the malfunction code "

E3

", "

E4

", "

L8

" or "

U0

" is displayed on the 

remote controller, there is a possibility that the stop valves are 
closed.

If the malfunction code "

E3

", "

E4

", "

L4

" or "

L8

" is displayed on the 

remote controller, there is a possibility that air inlet or air outlet 
are blocked.

If the malfunction code "

U2

" is displayed on the remote 

controller, check for voltage imbalance.

If the malfunction code "

U4

" or "

UF

" is displayed on the remote 

controller, check the inter-unit branch wiring connection.

The reversed phase protection detector of this product only 
works during the initialisation stage after a power reset.
The reversed phase protection detector is designed to stop the 
product in case of an abnormality when the product is started up.

When the reversed phase protection circuit forced the unit to 
stop, check if all phases are existing. If this is the case, shut 
off the power supply to the unit and replace two of three 
phases. Turn on power again and start the unit.

Reversed phase detection is not performed while the product 
is operating.

In case of possible reversal of phases after a momentary 
black out of power and the power goes on and off while the 
product is operating, install a reversed phase protection 
circuit on site. Such situation is not unimaginable when using 
generators. Running the product in reversed phase can 
break the compressor and other parts.

For a missing phase in case of Y1 units, "

E7

" or "

U2

" will be 

displayed on the remote controller of the indoor unit.
Operation will be impossible with either one of these 
phenomena. If this happens, turn off the power, re-check the 
wiring and switch the position of two of the three electrical wires. 
(If operation is not possible, do not under any circumstances 
force the electromagnetic contactor on.)
