WATER CONNECTIONS
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 connection piping should be supported in such a way
as to avoid it weighing on the unit.
The following devices must be installed on the water circuit:
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 out-
let);
4. A flow switch on the unit outlet to the system circuit
(compulsory). The flow switch must be calibrated by
the installer to a value 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.
7. All the pipes must be insulated with suitable material to
prevent the formation of condensate and heat loss. The
insulating material must be a vapour barrier. Make sure
that the control and shut-off devices protrude from the
insulation.

8. At the lowest points in the system, install drain valves for
easy emptying.
9. At the highest points in the system, install automatic or
manual air vent valves.
Failure to install the flow switch will mean the heat exchang-
er is not protected in the event of no flow of liquid.
Climaveneta 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 components 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 dis-
turbing operation of the refrigerant circuits.
