TART UP AND CONFIGURATION
ATTENTION
It is important that all information in this chapter is read
sequentially by the installer and that the system is
configured as applicable.
DANGER: ELECTRICAL SHOCK
See "4. General safety precautions" on page 3.

14.1. Pre-operation checks

After the installation of the unit, first check the following items. Once
all below checks are fulfilled, the unit must be closed, only then can
the unit be powered up.
1 Installation
Check that the unit is properly installed, to avoid abnormal
noises and vibrations when starting up the unit.
2 Electrical wiring
Field wiring
Be sure that the field wiring has been carried out according
to the instructions described in the chapter "13. Electric
wiring work" on page 11, according to the wiring diagrams
and according to the applicable legislation.
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.
Ground wiring
Be sure that the ground wires have been connected properly
and that the ground terminals are tightened.
Insulation test of the main power circuit
Using a mega tester for 500 V, check that the insulation
resistance of 2 MΩ or more is attained by applying a voltage
of 500 V DC between power terminals and ground. Never
use the mega tester for the transmission wiring.
Fuses, circuit breakers, or protection devices
Check that the fuses, circuit breakers, or the locally installed
protection devices are of the size and type specified in the
chapter "13. Electric wiring work" on page 11. Be sure that
neither a fuse nor a protection device has been bypassed.
Internal wiring
Visually check the switch box and the inside of the unit on
loose connections or damaged electrical components.
3 Refrigerant piping
Pipe size and pipe insulation
Be sure that correct pipe sizes are installed and that the
insulation work is properly executed.
Stop valves
Be sure that the stop valves are open on both liquid and gas
side.
4 Internal unit
Damaged equipment
Check the inside of the unit on damaged components or
squeezed pipes.
Refrigerant leak
Check the inside of the unit on refrigerant leakage. If there is
a refrigerant leak, call your local dealer. Do not touch any
refrigerant which has leaked out of refrigerant piping
connections. This may result in frostbite.
Oil leak
Check the compressor for oil leakage. If there is an oil leak,
call your local dealer.
Air inlet/outlet
Check that the air inlet and outlet of the unit is not obstructed
by paper sheets, cardboard, or any other material.

EST OPERATION
WARNING
During tests never pressurize the appliances with a
pressure higher
pressure (as indicated on the nameplate of the unit).
If refrigerant gas leaks, ventilate the area immediately.
Toxic gas may be produced if refrigerant gas comes
into contact with fire.
Never directly
refrigerant. This could result in severe wounds caused
by frostbite.
DANGER: DO NOT TOUCH PIPING AND INTERNAL
PARTS
See "4. General safety precautions" on page 3.
DANGER: ELECTRICAL SHOCK
See "4. General safety precautions" on page 3.

15.1. Test run recommendations

After installation, the installer is obliged to verify correct operation.
Therefore a test run must be performed according to the procedures
described below.

15.2. Maintenance and testing logbook

Provide a logbook and machine card.
In accordance with the applicable legislation, it may be necessary to
provide a logbook with the equipment containing at least: info on
maintenance, repair work, results of tests, stand-by periods, ....
Also, at least, following information shall be provided at an accessible
place of the system:
instructions for shutting down the system in case of an
emergency
name and address of fire department, police and hospital
name, address and day and night telephone numbers for
obtaining service.
NOTE Note that during the first running period of the unit,
required power input may be higher. This phenomenon
originates from the compressor that requires a 50 hour
run elapse before reaching smooth operation and
stable power consumption. Reason is that the moving
parts are made out of iron and that it takes some time
to smooth the surfaces that make contact.
NOTE To protect the compressor, be sure to turn on the
power supply 6 hours before starting operation.
