CAUTION
Select all cables and wire sizes in accordance with
applicable legislation.
CAUTION
After finishing the electrical work, confirm that each electric
part and terminal inside the electric part box is connected
securely.
For V3 models only: This equipment complies with respectively:
■ (1)
EN/IEC 61000-3-11 provided that the system impedance Z
is less than or equal to Z
max
(2)
■
EN/IEC 61000-3-12 provided that the short-circuit power S
is greater than or equal to the minimum S
at the interface point between the user's supply and the public
system. It is the responsibility of the installer or user of the equipment
to ensure, by consultation with the distribution network operator if
necessary, that the equipment is connected only to a supply with
respectively:
■
a system impedance Z less than or equal to Z
sys
■
a short-circuit power S greater than or equal to the minimum

EST OPERATION
DANGER
Never leave the unit unattended during installation or
servicing. When the service panel is removed live parts
can be easily touched by accident..
Note that during the first running period of the unit,
required power input may be higher than stated on the
nameplate of the unit. This phenomenon originates from
the compressor that needs elapse of a 50 hours run in
period before reaching smooth operation and stable power
consumption.
(1) European/International Technical Standard setting the limits for voltage
changes, voltage fluctuations and flicker in public low-voltage supply
systems for equipment with rated current 75 A.
(2) European/International Technical Standard setting the limits for harmonic
currents produced by equipment connected to public low-voltage systems
with input current >16 A and 75 A per phase.

15.1. Pre-run checks

Items to check
■
Electrical wiring Is the wiring as mentioned on the wiring diagram?
Inter-unit wiring Make sure no wiring has been forgotten and that
Earth wire there are no missing phases.
■
Is the unit properly earthed?
■
Is the wiring between units connected in series
correct?
■
Are any of the wiring attachment screws loose?
■
Is the insulation resistance at least 1 M ?
-
-
■
Refrigerant Is the size of the piping appropriate?
piping
■
Is the insulation material for the piping attached
securely?
Are both the liquid and gas pipes insulated?
■
Are the stop valves for both the liquid side and the
gas side open?
■
Extra Did you write down the extra refrigerant and the
refrigerant refrigerant piping length?
■
Be sure to perform a test run.
■
Be sure to fully open the liquid-side and gas-side stop valves. If
you operate the unit with stop valves closed, the compressor will
break down.
■
Never leave the unit unattended with an open front panel during
sys

test run.

■
To protect the compressor, make sure to turn on the power
sc
supply 6 hours before starting operation.
■
During tests never pressurize the applications with a pressure
higher than the maximum allowable pressure (indicated on the
name plate of the unit).
15.2. Test run
Carry out the test run in accordance with the indoor installation
manual to ensure that all functions and parts are working properly.
15.3. 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 "L4" is displayed on the remote controller, it is
possible that air inlet or air outlet are blocked.
■ For a missing phase, " 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.
Use a 500 V mega-tester when measuring
insulation.
Do not use a mega-tester for low-voltage circuits.
