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 

"Failure diagnosis at the moment of first

installation" on page 13

.

3

In case you cannot operate the unit in test run mode, the unit
usually returns to its normal state after 30 minutes.

4

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.

5

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.

6

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.

Failure diagnosis at the moment of first installation

In case nothing is displayed on the remote controller (the current
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 remote controller shows 

"

E3

", "

E4

or 

"

L8

"

 as an error code,

there is a possibility that either the stop valves are closed, or that
air inlet or air outlet are blocked.

If the error code 

"

U2

"

 is displayed on the remote controller, check

for voltage imbalance.

If the error code 

"

U4

"

 or 

"

UF

"

 is displayed on the remote

controller, check the inter-unit branch wiring connection.

If the error code 

"L4"

 is displayed on the remote controller, it is

possible that air inlet or air outlet are blocked.

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 W1 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.)

REQUIREMENTS

Dismantling of the unit, treatment of the refrigerant, of oil and of other
parts must be done in accordance with relevant local and national
legislation.
