UNIT IDENTIFICATION
SERIAL NUMBER LABEL
The units are identified by the serial number label shown here.
The label lists the type of unit (series and size), serial number, year
of manufacture, number of electrical diagram, main technical data,
logo and address of the manufacturer.
The label is placed on the unit, generally near the electrical panel
and also on the external panelling.
IT MUST NEVER BE REMOVED.
SERIAL NUMBER
This provides unique identification of the machine. It makes it
possible to trace the specific features of the unit and to identify the
components installed in it.
Without this number, it is not possible to identify with certainty the
spare parts that are specific to that unit.
When requesting assistance, always provide the type of machine
and the serial number.
Write them in the space below so that they are readily available
when needed.

GENERAL WARNINGS
MANUAL PURPOSE
This manual has been designed to enable the unit to be
installed, started up and maintained correctly.
MANUAL INSTRUCTIONS
It is essential to observe these instructions.
The manufacturer declines all liability for any damage that
may be caused whether directly or indirectly to persons or
things if these instructions are not heeded.
MANUAL STORE
This manual and the unit’s wiring diagram should be
carefully stored so that they are readily available to the
operator when required.
EXPERT PERSONAL
The unit must be installed, tested and maintained by expert
personal who meet the relevant legal requirements (Italian
law No. 46 of 5/3/1990).
LOCAL SAFET REGULATION INSTALLATION
The installation must be performed observing the local
safety regulations.
POWER SUPPLY
Make sure the power supply conforms to the data on the
unit’s rating plate, located inside the door of the main
electrical panel.
PACKAGING
The packaging material (plastic bags, polystyrene foam,
nails, etc.) is potentially dangerous and should therefore be
kept away from children and recycled in compliance with
the local regulations in force.
MAINTENANCE
Before performing any service operations, cut off the
power. Perform the operations in conformity with the local
regulations in force.
PERIODICAL INSPECTIONS
Perform periodical inspections to locate possible loosened
or broken parts. If the repairs are not performed, there will
be a higher risk for things and peoples to become damaged
and injured.
FAULT – POOR OPERATION
Switch off the unit in the event of faults or poor operation.
REPAIR
Only have repairs carried out by a service centre authorised
by the manufacturer, and insist on the use of original spare
parts only.
Failure to comply with the above may compromise the
safety of the unit.
MODIFICATIONS
The manufacturer will not accept any responsibility, and the
warranty will lapse, in the event of electric and/or
mechanical modifications. Any modification which is not
formally authorized, and which does not respect the
instructions given in this manual, will cause the warranty to
lapse.
INTENDED USE
The unit must only be used for the specific purpose it was
designed :
The unit is designed to cool/heat water or a water and
glycol mix for air-conditioning, within the limits defined
in the technical bulletin and this manual.
Any use other than that specified does not imply any
commitment or constraint by the manufacturer in any way
whatsoever.
ADDITIONAL SAFETY PRECAUTIONS
This unit has been especially designed and manufactured
so to prevent any risk to persons and health hazard.
For this reason, design solutions fit to eliminate (where
possible) any cause of risk and sensibly reduce the
probability of danger have been adopted.
Please refer to the "Residual Risks" section of this manual
and strictly observe the behaviour prescriptions listed there
in order to prevent any possible risk that hasn’t been
possible to avoid in the design stage.

ELECTRICAL CONNECTION
GENERAL
The characteristics of the electrical lines and relevant
components must be determined by SPECIALIZED
PERSONNEL ABLE TO DESIGN ELECTRICAL
INSTALLATIONS; moreover, the lines must be in
conformity with professional procedures and the regulations
in force.
All electrical operations should be performed by trained
PERSONNEL HAVING THE NECESSARY REQUISITES
UNDER LAW and being informed about the risks relevant
to these activities.
Before performing any operation on the electrical system,
make sure that the unit supply line is SELECTED AT
START.
The earth connection must be made prior to other electrical
connections.
For all electrical type operations, REFER TO THE
ELECTRICAL DIAGRAM ATTACHED TO THE UNIT; the
number of the diagram is shown on the registration plate
positioned on the electrical board or next to it.
The electrical diagram should be carefully kept together
with this manual and should be AVAILABLE FOR FUTURE
INTERVENTION ON THE UNIT.
LINE OF UNIT POWER SUPPLY
The ELECTRICAL DATA OF THE UNIT are shown in the
technical chart of this manual and on the unit registration
plate. The presence of accessories can vary according to
the unit; the electrical data shown in the technical chart
refer to standard units. In the event of differences between
the data of the registration plate and the data shown in this
manual, as well as in the technical chart, please refer to the
DATA SHOWN IN THE REGISTRATION PLATE.
The protection device of the unit power supply line should
break off the short circuit power whose value should be
determined according to the plant features.
The section of supply cables and protection cable must be
seized according to the characteristics of the protections
used.
SIGNALS / DATA LINES
Do not overpass the maximum power allowed, which
varies, according to the type of signal.
Lay the cables far from power cables or cables having a
different tension and that are able to emit electromagnetic
disturbances.
Do not lay the cable near devices which can generate
electromagnetic interferences.
Do not lay the cables parallel to other cables; cable
crossings are possible, only if laid at 90°.
Connect the screen to the ground, only if there are no
disturbances
Assure the continuity of the screen during the entire
extension of the cable.
Observe, if any, the requirements about impendency,
capacity, attenuation

CONNECTION TO THE MAINS
1. Make sure that the sectioning device at the beginning of
the unit’s power line is opened, locked and equipped
with a signal.
2. Open the general line disconnecting switch (if present)
3. Verify that the net is in conformity with the data shown
in the registration plate placed on the electrical board.
4. Check the dimensional drawing for the input of the
electrical lines
5. Take away the closing plate placed on the electric
board (ONLY IF PRESENT) and drill a hole through it
to pass the cables through)
6. Protect the cables, using the fairlead of an adequate
size.
7. Using the layout of the electrical diagram, single out the
connecting terminals of the electrical supply cables, of
the neutral (if foreseen) and the PE protection cable
8. Connect the cables to the relevant terminal boards
9. Before supplying power to the unit, make sure that all
the safety devices that were removed during electrical
connections are positioned again.
