GENERAL WARNINGS
These units have been designed to chill
and/or heat water and must be used in applica-
tions compatible with their performance char-
acteristics.
Incorrect installation, regulation and mainte-
nance or improper use absolve the manufac-
turer from all liability, whether contractual or
otherwise, for damage to people, animals or
things. Only those applications specifically indi-
cated in this list are permitted.
Read this manual carefully. All work must
be carried out by qualified personnel in confor-
mity with current legislation in the country
concerned.
The HRAT-HRAN units contain R22 refrigerant
gas which damages the ozone layer. At the end
of their working life, they should be taken to a
special collection centre, as per the legislation
in force. Care should be taken to avoid damage
to the gas circuit and coil.
The guarantee is invalidated if the above
instructions are not respected and if the unit is
started up for the first time without the pres-
ence of personnel authorised by the Company
(where specified in the supply contract) who
should draw up a “start-up” report.
The documentation supplied with the
unit must be consigned to the owner who
should keep it carefully for future consultation.
When the items are consigned by the
carrier, check that the packaging and the unit
are undamaged. If damage or missing compo-
nents are noted, indicate this on the delivery
note. A formal complaint should be sent via fax
or registered post to the After Sales Depart-
ment within eight days from the date of receipt
of the items.
When operating equipment involving the use of electricity
and water, a number of fundamental safety rules must be
observed, namely:
The unit must not be used by children or by
unfit persons without suitable supervision.
Do not touch the unit with bare feet or with
wet or damp parts of the body.
Do not carry out cleaning operations without
disconnecting the unit from the electricity supply by
placing the general installation switch in the “off”
position.
Do not modify safety or regulation devices
without authorisation and instructions from the
manufacturer.
Do not pull, detach or twist the electrical
cables coming from the unit, even when discon-
nected from the mains electricity supply.
Do not open doors or panels providing access
to the internal parts of the unit without first ensur-
ing that the general installation switch is in the off
position.
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, sta-
ples, 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 operations.

RECEIVING AND HANDLINGTHE PRODUCT
The chillers are supplied accompanied by:
-instruction manual;
-guarantee certificate;
-CE declaration.
These are contained in a plastic bag (A) attached to the
top of the chiller.
The unit should always be handled by qualified personnel
using equipment adequate for the weight of the chiller. If a
forklift truck is used, insert the forks under the bed plate,
spacing the forks as wide apart as possible. If a crane is
used, pass the cables through the bottom of the bed plate,
making sure they do not exert pressure on the unit. Once
the packaging has been removed, the unit can be lifted and
moved by inserting two metal tubes (max. diameter: 1”)
into the holes in the bed plate provided for this purpose
and using suitable handling equipment.
The instruction manual is an integral part of the
unit and should therefore be read and kept carefully.
It is recommended that the packaging should not
be removed until the unit is located in the installa-
tion site.
Do not dispose of packaging materials in the
environment or leave them within reach of children
as they may represent a hazard or source of pollution.
The weight of the chiller is biased towards the
compressor side (side of the packaging with the bar
code, see figure at the foot of the page).
During transport, the chiller should be kept in a
vertical position.

INSTALLATION
HYDRAULIC CONNECTIONS
CHOICE OF INSTALLATION SITE
Before installing the unit, agree with the customer the site
where it will be installed, taking the following points into
consideration:
-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 enter-
ing the unit and discharged by the fans is free to circulate.
-The unit must be installed in a space designed to house
technical installations dimensioned according to current
legislation in the country concerned and large enough to
allow access for maintenance. If this is not possible,
then use of the protection grill kit is indispensable
(HRAT-HRAN only).
POSITIONING
Before handling the unit, check the capacity of the lift equip-
ment used, respecting the instructions on the packaging.
To move the unit in the horizontal, make appropriate use
of a lift truck or similar, bearing in mind the weight distrib-
ution of the unit. To lift the unit, insert tubes long enough
to allow positioning of the lifting slings and safety pins into
the special holes in the bed plate of the unit.
To avoid the slings damaging the unit, place protection
between the slings and the unit.
Position the unit in the site indicated by the customer.
Place either a layer of rubber (min. thickness 10 mm) or
vibration damper feet (optional) between the bed plate
and support surface.
Fix the unit, making sure it is level and that there is easy
access to hydraulic and electrical components.
If the site is exposed to strong winds, fix the unit ade-
quately to the support surface using tie rods if necessary.
If a heat pump unit is being installed, fit a condensate col-
lection pan (available as accessory).
The choice and installation of components is the responsi-
bility of the installer who should follow good working prac-
tice and current legislation. Before connecting the pipes,
make sure they do not contain stones, sand, rust, dross or
other foreign bodies which might damage the unit.
Construction of a by-pass is recommended to enable the
pipes to be washed through without having to disconnect
the unit (see drain valves).The connection piping should be
supported in such a way as to avoid it weighing on the unit.
It is recommended that the following devices are installed
in the hydraulic circuit of the evaporator.
1. Two pressure gauges with a suitable scale (inlet and outlet);
2. Two vibration damper joints (inlet and outlet);
3. Two gate valves (normal in inlet and calibrating in outlet);
4. A flow switch (in inlet) or a differential pressure switch
(inlet-outlet);
5. Two thermometers (inlet and outlet);
6. An inlet filter as close as possible to the evaporator and
positioned to allow easy access for routine maintenance.
The flow of water to the refrigerating assembly must con-
form to the values given on page 17-18.The flow of water
must be maintained constant during operation.
The water content of the unit must be such as to avoid
disturbing operation of the refrigerant circuits.
See the values given on page 26.

If the installation requires a useful head higher than that
obtained by installing a pump assembly and storage tank,
it is recommended that an additional pump is installed
on the unit.
The pump can be easily installed on the unit by removing
the special pipe stub provided. Connect to terminal 4, 5
on the electrical panel.
The chillers must be provided with a filling/top-up
system connected to the return line and a drain cock
in the lowest part of the installation. Installations con-
taining anti-freeze or covered by specific legislation
must be fitted with hydraulic disconnectors.
The manufacturer is not liable for obstruction,
breakage or noise resulting from the failure to
install filters or vibration dampers.
Particular types of water used for filling or top-
ping up must be treated with appropriate treatment
systems. For reference values, see the table.
FILLINGTHE INSTALLATION
-Before filling, check that the installation drain cock is
closed.
-Open all installation and terminal air vents.
-Open the gate valves.
-Begin filling, slowly opening the water filling cock outside
the unit.
-When water begins to leak out of the air vent valves of
the terminals, close them and continue filling until the
pressure gauge indicates a pressure of 1.5 bars.
The installation must be filled to a pressure of
between 1 and 2 bars.
It is recommended that this operation be repeat-
ed after the unit has been operating for a number
of hours.The pressure of the installation should be
checked regularly and if it drops below 1 bar, the
water content should be topped-up.
Check hydraulic connections for tightness.

ELECTRICAL CONNECTIONS
The chillers leave the factory completely cabled and ready
for connection to the mains electricity supply and for the
flow switch, remote ON/OFF switch and pump to be con-
nected to the terminals provided. Electrical connections
must be carried out by qualified personnel in respect of
current legislation.
For all electrical work, refer to the electrical wiring dia-
grams in this manual.
You are also recommended to check that:
-The characteristics of the mains electricity supply are
adequate for the power ratings indicated in the electrical
characteristics table below, also bearing in mind the pos-
sible use of other equipment at the same time.
Power to the unit must be turned on only after
installation work (hydraulic and electrical) has been
completed.
All electrical connections must be carried out
by qualified personnel in accordance with current
legislation in the country concerned.
Respect instructions for connecting phase, neu-
tral and earth conductors.
The power line should be fitted upstream with a
suitable device to protect against short-circuits and
leakage to earth, isolating the installation from oth-
er equipment.
Voltage must be within a tolerance of ±10%
of the rated power supply voltage for the unit (for
three phase units, the unbalance between the phas-
es must not exceed 3%).
If these parameters are not respected, contact the
electricity supply company.
For electrical connections, use double insulation
cable in conformity with current legislation in the
country concerned.
Install, if possible near the unit, an appropriate
protection device to isolate the unit from the mains
supply with delayed characteristic curve, contacts
opening by at least 3 mm and an adequate interrup-
tion and differential protection capacity.
If this device is not visible from the electrical
panel of the unit, it should be lockable
An efficient earth connection is obligatory.
Failure to earth the appliance absolves the manufac-
turer of all liability for damage.
In the case of three phase units, ensure the
phases are connected correctly.
Do not use water pipes to earth the unit.
