Introduction

These water coolers are monoblock units for the production of
cooled water in a closed circuit.
The fan, pump and compressor motors are equipped with a ther-
mal protector that protects them against possible overheating.
2.1 Transport
The packed unit must remain:
a) upright;
b) protected against atmospheric agents;
c) protected against impacts.
2.2 Handling
Use a fork--- lift truck suitable for the weight to be lifted, avoiding
any type of impact.
2.3 Inspection
a) All the units are assembled, wired, charged with refrigerant
and oil and tested in the factory;
b) on receiving the machine check its condition: immediately
notify the transport company in case of any damage;
c) unpack the unit as close as possible to the place of installa-
tion.
2.4 Storage
a) Keep the unit packed in a clean place protected from damp
and bad weather.
b) do not stack the units;
c) follow the instructions given on the package.

Installation

Y
For correct installation, follow the instructions given in par.
7.2 and 7.3.
!
Liquids to be chilled
The liquids to be chilled must be compatible with the materials
used.
English
Examples of liquids used are water or mixtures of water and
ethylene or propylene glycols.
The liquids to be chilled must not be flammable.
If the liquids to be chilled contain hazardous substances (e.g. eth-
ylene/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 reg-
ulations and do not disperse the contents in the environment.
3.1 Operating space
Leave a space of 1 m around the unit.
3.2 Versions
Axial fans
Do not create cooling air recirculation situations.
Do not obstruct the ventilation grilles.
The 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 filling the water circuit,
check that all the pipes are clean. If not, wash them out thorou-
ghly.
Y
If the plumbing circuit is of the closed type, under pressure
it is advisable to install a safety valve set to 6 bar.
Y
Always install mesh filters on the water inlet and outlet pipe-
lines.
Y
If the hydraulic circuit is intercepted by automatic valves,
protect the pump with an anti--- hammering system.
Preliminary checks
1) Check that any shut--- off valves in the water circuit are open.
2) 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 water cooler to the inlet and outlet piping, using
the special connections located on the back of the unit.
We recommend the use of flexible unions to reduce system
rigidity.
2) Fill the water circuit using the fitting provided on the rear of
the chiller.
3) We recommend that taps are installed on the inlet and outlet
pipes, so that the unit can be excluded for maintenance when
necessary.
Subsequent checks
1) Check that the circuit is completely full of water and that all
the air has been expelled from the system.
2) The water circuit must always be kept full. For this reason,
carry out periodic checks and top the circuit up if necessary,
or install an automatic filling kit.
3) Check that the temperature of the cooled water does not fall
below 5˚C and that the ambient temperature in which the wa-
ter circuit operates does not fall below 5˚C.
If the temperature does fall below this value, add the recom-
mend quantity of glycol as explained in paragraph 3.3.2.
4) Check correct operation of the pump using a pressure gauge
(read P1 and P0) and the pressure limit values (Pmax and
Pmin) stated on the pump dataplate.
P1 = pressure with pump ON
P0 = pressure with pump OFF
Pmin < (P1--- P0) < Pmax
Subsequently check that the amp value of the pump is within
the dataplate specifications.
