INSTALLATION

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 fi xing 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 (see fi g. page 6).
- The unit must be installed in a space designed to hou-
se technical installations dimensioned according to le-
gislation 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.

HYDRAULIC CONNECTIONS

The choice and installation of components is the respon-
sibility of the installer who should follow good working
practice 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 bypass is recommended to ena-
ble 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 fol-
lowing 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).

To move the unit in the horizontal, make appropriate use
of a lift truck or similar, bearing in mind the weight distri-
bution 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 ex-
posed to strong winds,
fi x the unit adequately to the support surface using tie
rods if necessary.
4. A fl ow switch (inlet).
5. Two thermometers (inlet and outlet).
6. An inlet fi lter as close as possible to the evapora-
tor and positioned to allow easy access for routine
maintenance.
7. Check valve on hydraulic circuit if more than one unit
is connected in parallel.
The fl ow of water to the refrigerating assembly must con-
form to the values given on page 11. The fl ow of water
must be maintained constant during operation. The wa-
ter content of the unit must be such as to avoid disturbing
operation of the refrigerant circuits.
