HYDRAULIC CONNECTIONS
6English 07/07
CHOICE OF INSTALLATION SITE
Before installing the unit, agree with the customer the site
where it will be installed, taking the following points into consid-
eration:
- 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 circulate.
- The unit must be installed in a space designed to house techni-
cal installations dimensioned according to legislation in force in
the country concerned and large enough to allow access for
maintenance.
POSITIONING
Before handling the unit, check the capacity of the lifting
equipment 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 distribution of
the unit. To lift the unit, insert tubes long enough to allow
positioning 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. 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 base 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 adequately to the support surface using tie rods if
necessary.
The choice and installation of components is the responsibility of
the installer who should follow good working practice and cur-
rent legislation. Before connecting the pipes, make sure they do
not contain stones, sand, rust, dross or other foreign bodies whi-
ch might damage the unit. Construction of a bypass is recommen-
ded 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 water 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 (inlet).
5. Two thermometers (inlet and outlet).
6. An inlet filter as close as possible to the evaporator and posi-
tioned to allow easy access for routine maintenance.
The flow of water to the refrigerating assembly must conform to
the values given on page 12.The flow of water must be maintai-
ned 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 17.

ELECTRICAL CONNECTIONS
ICS / ICS-N
8English 07/07
The ICS / ICS-N chillers leave the factory already
wired, and ready for connection to the mains electricity sup-
ply and for the flow switch and remote ON/OFF switch to be
connected. All the above operations must be carried out by
qualified personnel in compliance with the legislation in force.
For all electrical work, refer to the electrical wiring diagrams
in this manual.You are also recommended to check:
- That the characteristics of the mains electricity supply
are adequate for the power input values indicated in the
electrical characteristics table below, also bearing in mind
the possible use of other equipment at the same time.
Power to the unit must be turned on only after
installation work (mechanical, hydraulic and electri-
cal) has been completed.
All electrical connections must be carried out
by qualified personnel in accordance with legislation
in force 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 other equipment.
Voltage must be within a tolerance of ±10% of the rat-
ed power supply voltage for the unit (for three phase
units, the unbalance between the phases must not
exceed 3%). If these parameters are not respected, con-
tact 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.This should have a delayed character-
istic curve, contacts opening by at least 3 mm and an
adequate interruption and residual current protection
capacity.
If these devices are not visible from the unit,
they should be lockable.
An efficient earth connection is obligatory. Fail-
ure to earth the appliance absolves the manufactur-
er 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.
