L1, L2 and L3 terminals of the main switch as shown on the
wiring diagram.
2 Connect the earth conductor (yellow/green) to the earthing
terminal PE.
Point for attention regarding quality of the public
electric power supply
This equipment complies with EN/IEC 61000-3-11
(1)
provided
that the system impedance Z
sys
is less than or equal to Z
max
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 a system impedance Z
sys
less than or
equal to Z
max
.

OPERATING THE UNIT
BEFORE OPERATION
Checks before initial start-up
After the installation of the unit, check the following before switching
on the circuit breaker:
1 Field wiring
Make sure that the field wiring between the local supply panel
and the unit has been carried out according to the instructions
described in the the chapter "Field wiring" on page 8, according
to the wiring diagrams and according to European and national
regulations.
2 Fuses or protection devices
Check that the fuses or the locally installed protection devices
are of the size and type specified in the chapter "Electrical
specifications" on page 4. Make sure that neither a fuse nor a
protection device has been bypassed.
3 Earth wiring
Make sure that the earth wires have been connected properly
and that the earth terminals are tightened.
4 Internal wiring
Visually check the switch box on loose connections or damaged
electrical components.
5 Fixation
Check that the unit is properly fixed, to avoid abnormal noises
and vibrations when starting up the unit.
6 Damaged equipment
Check the inside of the unit on damaged components or
squeezed pipes.
7 Refrigerant leak
Check the inside of the unit on refrigerant leakage. If there is a
refrigerant leak, call your local dealer.
8 Oil leak
Check the compressor on oil leakage. If there is an oil leak, call
your local dealer.
9 Air inlet/outlet
Check that the air inlet and outlet of the unit is not obstructed by
paper sheets, cardboard, or any other material.
10 Power supply voltage
Check the power supply voltage on the local supply panel. The
voltage must correspond to the voltage on the identification label
of the unit.
11 Ball valve and filter kit
Make sure that the ball valve and filter kit are correctly installed.
12 Pressure regulating valve and shut-off valve
Check that the pressure regulating valve (only for EUWYP and
EUWYB) and the shut-off valves are fully open.
(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.
