II.5.3 CLEARANCE SPACES, POSITIONINGAND
DUCTING
The unit is designed for indoor installation. It should be installed in
compliance with the minimum recommended clearances, bearing in
mind access to water and electrical connections on the right-hand side
of the machine. The unit should be correctly levelled and positioned on
a supporting surface capable of sustaining its full weight. It must not be
installed on brackets or shelves.
In order to allow TCCE THCE to function correctly, it is best to prevent
the inlet air from mixing with the outlet air. We therefore recommend
ducting and expelling the fan outlet air outside the room in which the
unit is installed.
The outlet ducts must have a constant section, equal to the fan outlet
section. In order to prevent vibrations from being transmitted, the KRAM
kit (outlet anti-vibration connection) is available which makes it possible
to disconnect the unit from the duct. We therefore recommend
introducing some elastic connections on the air duct, in correspondence
to the points in which it runs through the walls of the room.
The room where the unit is to be installed must be provided with an
opening that makes it possible to take in air from outside, with a section
equivalent to that of the finned coil.
The inlet can be ducted if necessary. The KRAS kit (inlet anti-vibration
connection) is available in order to prevent vibrations from being
transmitted.
When installing the ducting, it is necessary to assess the total air
pressure drops during nominal flow. These should not exceed the
useful static pressure corresponding to the flow itself.

The following accessories are available to reduce noise and
vibration:
KSA - Anti-vibration mountings.
KRAS – Inlet anti-vibration connection.
KRAM – Outlet anti-vibration connection.
When installing the unit, bear the following in mind:
• non-soundproofed reflecting walls near the unit may increase the
total sound pressure level reading near the appliance by as much as 3
dB(A) for every surface;
• install suitable anti-vibration mountings under the unit to avoid
transmitting vibrations to the building structure;
• make all water connections using elastic joints. Pipes must be firmly
supported by solid structures. If the pipes are routed through walls or
panels, insulate with elastic sleeves. If, after installation and start-up of
the unit, structural vibrations are observed in the building which provoke
such strong resonance that noise is generated in other parts of the
building, consult a qualified acoustic technician for a complete analysis
of the problem.

WATER CONNECTIONS

II.6.1.1 Connection to the system
The unit is equipped with male threaded water connections and with a
manual air bleed valve inside the bodywork, near the upper and lower
water connections; they are also present on the pump compartment in
the T and H versions.
In T and H versions, fit the draincock in the storage tank supplied with
the machine.
The water flow through the heat-exchanger should not fall below a
value corresponding to a temperature differential of 10°C.
It is good practice for a correct functioning of the machine to make sure
that the system has a good water content, in order to ensure sufficient
thermal inertia to prevent one start after another.
Remember that there is a time delay built into the machine which
prevents restart for three minutes after stopping.
In the T and H versions, this manual is supplied together with the pump
or circulating pump use and maintenance manual.
II.6.1.2 Protecting the unit from frost
When the unit is running, the control board protects the water-side heat-
exchanger from freezing by making the antifreeze alarm cut in, stopping
the machine if the temperature of probe fitted on the heat-exchanger
reaches the set point value.
Any residual water left in the pump drained using the screw provided for
this purpose.
If the draining operation is felt to be too much trouble, ethylene glycol
126
may be mixed with the water in suitable proportions in order to
800
guarantee protection from freezing.

SECTION II: INSTALLATION AND MAINTENANCE
IMPORTANT!
Incorrect positioning or installation of the unit may
amplify noise levels and vibrations generated
during operation.
IMPORTANT!
We recommend installing isolating valves that
isolate the unit from the rest of the system. It is
obligatory to install a network filter outside the
machine's water inlet. Clean the filter from time to
time.
IMPORTANT!
If the mains switch is opened, it cuts off the
electricity supply to the storage tank plate
exchanger heater and the storage tank antifreeze
heater if that device is present. The switch should
only be disconnected for cleaning, maintenance or
repair of the machine.
IMPORTANT!
When the unit is out of service, drain all the water
contents from the circuit.
