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.
