INSTALLATION
U I A
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 support surface is adequate to support the
weight of the unit;
- respect safety distances between the unit and other equip-
ment or structures.
- The unit must be installed in a space designed to house tech-
nical installations dimensioned according to legislation in
force in the country concerned and large enough to allow
access for maintenance.
POSIZIONAMENTO
Before handling the unit, check the capacity of the lift equip-
ment used, respecting the instructions on the packaging.
To move the unit horizontally, make appropriate use of a lift truck
or similar, bearing in mind the weight distribution of the unit.
Fix the unit, making sure it is level and that there is easy
access to water and electrical components.
WATER CONNECTIONS
I A
The choice and installation of components is the responsibil-
ity of the installer who should follow good working practice
and current legislation. Construction of a bypass is recom-
mended to enable the pipes to be washed through without
having to disconnect the unit (see drain valves). The con-
nection piping should be supported in such a way as to
avoid it weighing on the unit. The following components
must be installed in the water circuits:
1. Two pressure gauges with a suitable scale (intake and
outlet);
2. Two vibration damper joints (intake and outlet).
3. Two shut off valves (normal in intake and calibrating in
outlet).
4.
Two flow switches (outlet) on both circuits, in the
system and source sections (compulsory). Both flow
switches must be calibrated by the installer to a val-
ue equal to 70% of rated flow.
5. Two thermometers (intake and outlet).
6.
An intake filter must be installed as close as possible
to the evaporator and positioned to allow easy access
for routine maintenance. 500 micron filter mesh.
Failure to install the flow switch will mean the heat exchang-
er is not protected in the event of no flow of liquid. Cli-
maveneta cannot be held liable for any damage to the unit
and/or the system following the failure to install these
devices or the filter. The correct operation of the compo-
nents that help ensure the safety of the appliance and the
system should be checked regularly.
Specifically, this involves cleaning the filters and checking
the operation of the flow switches installed.
Water flow to the chiller unit must conform to the values
shown in the section on “General Technical Data”.
The flow of water must be maintained constant during oper-
ation. The water content of the unit must be such as to avoid
disturbing operation of the refrigerant circuits.
Install any pressure regulating valves or solenoid valves on
the external water outlet piping
