GENERAL WARNINGS U I A
FUNDAMENTAL SAFETY RULES U I A
These appliances have been designed to chill and/or
heat water and must be used in applications compatible
with their performance characteristics; these appliances
are designed for residential or similar applications.
Incorrect installation, regulation and maintenance or
improper use absolve the manufacturer from all liability,
whether contractual or otherwise, for damage to people,
animals or things.
Only those applications specifically indicated in this list
are permitted
Read this manual carefully. All work must be carried
out by qualified personnel in conformity with legislation in
force in the country concerned.
The warranty is void if the above instructions are not
respected and if the unit is started up for the first time
without the presence of personnel authorised by the
Company (where specified in the supply contract) who
should draw up a “start-up” report.
The documents supplied with the unit must be con-
signed to the owner who should keep them carefully for
future consultation in the event of maintenance or ser-
vice.
All repair or maintenance work must be carried out by
the Company’s Technical Service or qualified personnel
following the instructions in this manual.
The air-conditioner must under no circumstances be
modified or tampered with as this may create situations
of risk. Failure to observe this condition absolves the
manufacturer of all liability for resulting damage.
Ricordiamo che l’utilizzo di prodotti che impiegano energia elettrica ed acqua, comporta l’osservanza di alcune regole fonda-
mentali di sicurezza quali:
The unit must not be used by children or by unfit per-
sons without suitable supervision.
Do not touch the unit with bare feet or with wet or
damp parts of the body.
Never perform any cleaning operations before having
disconnected the unit from the mains power supply.
Do not modify safety or control devices without authori-
sation and instructions from the manufacturer.
Do not pull, detach or twist the electrical cables coming
from the unit, even when disconnected from the mains
electricity supply.
Do not open doors or panels providing access to the
internal parts of the unit without first ensuring that the
switch QF1 is in the OFF position (see the wiring dia-
gram).
Do not introduce pointed objects through the air
intake and outlet grills.
Do not dispose of, abandon or leave within reach of
children packaging materials (cardboard, staples, plastic
bags, etc.) as they may represent a hazard.
Respect safety distances between the unit and other
equipment or structures. Guarantee adequate space for
access to the unit for maintenance and/or service opera-
tions.
Power supply: the cross section of the electrical cables
must be adequate for the power of the unit and the pow-
er supply voltage must correspond with the value indicat-
ed on the respective units. All units must be earthed in
conformity with legislation in force in the country con-
cerned.
Terminals 6, 7, 9, 10, 11, 12, 13, 21, 22 on the inside
module may be live even when the unit has been dis-
connected. Check for voltage before proceeding.
Water connections should be carried out as indicated in
the instructions to guarantee correct operation of the
unit. Add glycol to the water circuit if the unit is not used
during the winter or the circuit is not emptied.
Handle the unit with the utmost care (see weight distrib-
ution table) to avoid damage.
WAIVER OF LIABILITY
This publication is the sole property of Manufacturer. Any
reproduction or disclosure of such is strictly prohibited with-
out the written authorisation of Manufacturer.
This document has been prepared with maximum care and
attention paid to the content shown. Nonetheless, Manufac-
turer waives all liability deriving from the use of such docu-
ment.
Read this document carefully. All work must be performed,
components selected and materials used in complete accor-
dance with the legislation in force in material in the country
concerned, and considering the operating conditions and
intended uses of the system, by qualified personnel.

VISUAL INSPECTION
When the items are consigned by the carrier:
- make sure that the goods delivered correspond to the
description on the delivery note, comparing this against
the data on the packaging label.
- make sure the packaging and the unit are intact.
If damage or missing components are noted, indicate this on
the delivery note. A formal complaint should be sent via fax
or registered post to the After Sales Department within eight
days from the date of receipt of the items.
HANDLING PACKAGED UNITS
The unit should always be handled by qualified personnel
using equipment adequate for the weight of the unit, in com-
pliance with the safety standards in force (and subsequent
amendments).
•Lifting by forklift (1)
Insert the forks under the long side of base, opening the
forks as fare as possible.
•Lifting by crane (2)
Use slings with hooks suitable for the weight being lifted.
Secure the hook to the lifting bracket fixed to the unit, use
always four equal length slings, as shown in the figure, to
ensure the weight is balanced.
The weight of the unit is biased towards the compres-
sor side.
During transport, the unit should be kept in a vertical
position.
STORING THE UNITS
The units must be stored sheltered from direct sunlight, rain,
wind or sand.
Avoid exposing the units to direct sunlight, as the pressure
inside the refrigerant circuit may reach dangerous values
and cause the activation of the safety valves, where fitted.
The units cannot be stacked.
The packaging should not be removed until the unit is
located in the installation site.

RATING PLATE
Describes the unit technical and performance specifications.
Shows the serial number used to uniquely identify the unit.
The serial number is also used to identify the unit’s spare

If service is required, the following information must be pro-
vided to the service centre:
Model, serial number, year of production.
Installation and maintenance operations are much more
difficult if the identification plates or anything else need-

HEAT PUMP INSTALLATION I A
POSITIONING
• Before handling the unit, check the capacity of the lift
equipment used, respecting the instructions on the pack-
aging.
• To move the unit horizontally, make appropriate use of a
lift truck or similar, bearing in mind the weight distribution
of the unit.
• To lift the unit, insert tubes long enough to allow position-
ing of the lifting slings and safety pins in the special holes
in the base of the unit.
• To avoid the slings damaging the unit, place protection
between the slings and the unit.
• The unit should be installed on special vibration dampers.
• See the chapter on DIMENSIONAL DRAWINGS for the
support positions and the corresponding weights for the
correct sizing of the vibration dampers.
• Fix the unit, making sure it is level and that there is easy
access to water and electrical components.
• If the site is exposed to strong winds, fix the unit ade-
quately using tie rods if necessary.
• In heating mode the unit produces a significant quantity of
condensate, which must be suitably drained. Condensate
drainage must not cause problems to objects or people.
• If the outside air temperature is less than 0°C, the conden-
sate may freeze; in these case fit a frost protection heater
on the drain line.
• For correct operation of the unit, avoid the following:
- bstacles to air flow
- leaves that may block the heat exchange coil
- strong winds that stop or reinforce air flow
- sources of heat too close to the unit, recirculation or
stratification of air
CHOICE OF INSTALLATION SITE
Before installing the unit, agree with the customer the site
where it will be installed, taking the following points into con-
sideration:
• Check that the fixing points are adequate to support the
weight of the unit;
• Pay scrupulous respect to safety distances between the
unit and other equipment or structures to ensure that air
entering the unit and discharged by the fans is free to cir-
culate.
• Follow the instructions shown in the chapter on “Minimum
clearances” to allow room for maintenance operations.
• Unit for outdoor installation
If installing multiple units the clearances must be doubled.
