1.1 Introduction
Itelco-Industry units, manufactured to state-of-the-art
design and implementation standards, ensure top
performance, reliability and fitness to any type of air-
conditioning systems.
These units are designed for cooling water or glyco-
led water (and for water heating in heat pump mo-
dels) and are unfit for any purposes other than those
specified in this manual.
This manual includes all the information required for
a proper installation of the units, as well as the rele-
vant operating and maintenance instructions.
It is therefore recommended to read this manual ca-
refully before installation or any operation on the
machine. The chiller installation and maintenance
must be carried out by skilled personnel only (where
possible, by one of Itelco-Industry’s Authorised Servi-
ce Centers).
The manufacturer may not be held liable for any da-
mage to people or property caused by improper in-
stallation, start-up and/or improper use of the unit
and/or failure to implement the procedures and in-
structions included in this manual.
1.2 Warranty
These units are delivered complete, tested and ready
for being operated. Any form of warranty will beco-
me null and void in the event that the appliance is
modified without Itelco-Industry’s preliminary written
authorisation.
This warranty shall apply providing that the installa-
tion instructions have been complied with (either is-
sued by Itelco-Industry, or deriving from the current
practice), and the Form 1 (“Start-up”) has been filled-
in and mailed to Itelco-Industry (attn. After-Sales Ser-
vice).
In order for this warranty to be valid, the following
conditions shall be met:
I
The machine must be operated only by skilled per-
sonnel from Itelco-Industry’s Authorised After-Sales
Service.
I
Maintenance must be performed only by skilled
personnel - from one of Itelco-Industry’s Authorised
After-Sales Centers.
I
Use only original Itelco-Industry spare parts.
I
Carry out all the planned maintenance provided
for by this manual in a timely and proper way.
Failure to comply with any of these conditions will
automatically void the warranty.
1.3 Emergency stop / Normal stop
The emergency stop of the unit can be enabled using
the master switch on the control panel (move down
the lever).
For a normal stop, press the relevant push-buttons.
To restart the appliance, follow the procedure detai-
led in this manual.
1.4 An introduction to the manual
For safety reasons, it is imperative to follow the in-
structions given in this manual. In case of any dama-
ge caused by non-compliance with these instruc-
tions, the warranty will immediately become null and
void.
Conventions used throughout the manual:

people and property.
The Warning sign precedes those procedu-
res that, if not followed, may result in se-
rious damage to the appliance.
The Notes contain important observations.
The Useful Tips provide valuable informa-
tion that optimises the efficiency of the ap-
pliance.
