Installation

Y
For correct installation, follow the instructions given in par.7.2,
7.3 and 7.7.
!
It is recommended that all chillers be fi tted with adequate pre-
fi ltration near the inlet water to the chiller.
!
Liquids to be chilled
Th e liquids to be chilled must be compatible with the materials used.
Examples of liquids used are water or mixtures of water and ethylene
or propylene glycols or oil.
Th e liquids to be chilled must not be fl ammable.
If the liquids to be chilled contain hazardous substances (e.g. ethylene/
propylene glycol), any liquid discharged from a leakage area must be
collected, because it is harmful to the environment. When draining
the hydraulic circuit, comply with the current regulations and do not
disperse the contents in the environment.

3.1 Operating space

Leave a space of 1.5 m around the unit.
Leave a space of at least 2 metres above the refrigerator in models with
vertical emission of condensation air.

3.2 Versions

Axial fans (A)
Do not create cooling air recirculation situations.
Do not obstruct the ventilation grilles.
Th e ducting of extracted air is not recommended for versions with
axial fans.

3.3 Water circuit

3.3.1 Checks and connection
Y
Before connecting the chiller and fi lling the circuit, check that all
the pipes are clean. If not, wash them out thoroughly.
Y
If the plumbing circuit is of the closed type, under pressure it is
advisable to install a safety valve set to:
ICEP002 (60Hz)
6 bar (for water version)
Y
(for water version) Always install mesh fi lters on the water inlet
and outlet pipelines.
Y
If the hydraulic circuit is intercepted by automatic valves, protect
the pump with an anti-hammering system.
Y
(for water version) If the hydraulic circuit is emptied for shut-
down periods we recommend that you add lubricating fl uid to the
pump's impeller to avoid the risk of blockage when it is re-started. In
case the impeller is blocked then you should unblock it manually.
Remove the rear cover of the pump and carefully turn the plastic fan.
If the impeller is stuck then remove the fan and turn the impeller shaft
directly. Aft er un-blocking the impeller re-assemble the fan and cover.
Preliminary checks
1) Check that any shut-off valves in the idraulic circuit are open.
2) (for water version) In the case of a closed water circuit, check
that an expansion tank of suitable capacity has been installed. See
paragraph 3.3.3.
Connection
1) Connect the cooler to the inlet and outlet piping, using the special
connections located on the back of the unit.
We recommend the use of fl exible unions to reduce system rigidity.
2) (for water version) Fill the water circuit using the fi tting provided
on the rear of the chiller ( ).
3) (for water version) Th e tank is equipped with a breather valve
that should be operated manually when fi lling the tank. Also, if the
hydraulic circuit has high points, install a vent valve at the highest
points.
4) We recommend that taps are installed on the inlet and outlet pipes,
so that the unit can be excluded for maintenance when necessary.
5) If the chiller works with an open tank, the pump must be installed
on intake to the tank and on delivery to the chiller.
Subsequent checks
1) (for water version) Check that the tank and the circuit are com-
pletely full of water and that all the air has been expelled from the
system.
2) (for water version) Th e water circuit must always be kept full. For
this reason, carry out periodic checks and top the circuit up if neces-
sary, or install an automatic fi lling kit.
3.3.2 Water and ethylene glycol (water version)
If installed outdoors or in an unheated indoor area, it is possible that
the water in the circuit may freeze if the system is not in operation dur-
ing the coldest times of the year.
To avoid this hazard:
a) Equip the chiller with suitable antifreeze protection devices, avail-
able from the manufacturer as optional accessories;
b) Drain the system via the drain valve if the chiller is to remain idle
for a prolonged period;
c) Add an appropriate quantity of antifreeze to the water in circula-
tion (see table).
Sometimes the temperature of the outlet water is so low as to require
the addition of ethylene glycol in the following percentages.

3.3.3 Expansion tank (water version)
To avoid the possibility of an increase or decrease in the volume of the
fl uid due to a signifi cant change in its temperature causing damage to
the machine or the water circuit, we recommend installing an expan-
sion tank of suitable capacity.
Th e expansion tank must be installed on intake to the pump on the
rear connection of the tank.
Th e minimum volume of an expansion tank to be installed on a closed
circuit can be calculated using the following formula:
V=2 x Vtot x (Pt min - P t max)
where
Vtot= vol. circuit total (in litres)
P t min/max= specifi c weight at the minimum/maximum temperature
reached by the water [kg/dm3].
Th e specifi c weight values at diff erent temperatures for glycol percent-
age values are given in the table.

Caution: When fi lling the system, take into account the capac-
ity of the expansion vessel as well.
