AFETY
This machinery was designed to be safe in the use for which it was planned provided that it is installed, started up and
maintained in accordance with the instructions contained in this manual.
The manual must therefore be studied by all those who want to install, use or maintain the unit.
The machine contains electrical components which operate at the line voltage, and also moving parts as fans and/or pump.
It must therefore be isolated from the electricity supply network before being opened.
All maintenance operations which require access to the machinery must be carried out by expert or appropriately trained
persons who have a perfect knowledge of the necessary precautions.
Avoid the presence of children in the unit installation place.

G e n e r a l
When handling or maintaining the unit and all auxiliary equipment, the personnel must operate with care observing all
instructions concerning health and safety at installation site.
Most accidents which occur during the operation and maintenance of the machinery are a result of failure to observe basic
safety rules or precautions.
An accident can often be avoided by recognising a situation that is potentially hazardous.
The user should make sure that all personnel concerned with operation and maintenance of the unit and all auxiliary
equipment have
read and understood
all warnings, cautions, prohibitions and notes written in this manual as well as on the
unit.
Improper operation or maintenance of the unit and auxiliary equipment could be dangerous and result in an accident causing
injury or death.
Do not
operate the unit and auxiliary equipment until the instructions in the Operating section of this manual are understood
by all personnel concerned.
Do not
carry out any servicing, repair or maintenance work on the unit and auxiliary equipment until the instructions in the
relevant sections of this manual are clearly understood by all personnel concerned.
We cannot anticipate every possible circumstance which might represent a potential hazard.
The warnings in this manual are therefore not all-inclusive.
If the user employs an operating procedure, an item of equipment or a method of working which is not specifically
recommended, he must ensure that the unit and auxiliary equipment will not be damaged or made unsafe and that there is no
risk to persons or property.
Any improper use of the machine will relieve the manufacturer from any liability for possible personal injury or property
damage.
Arbitrary modifications made to the unit will automatically invalidate all forms of guarantee provided by the manufacturer.
ATTENTION
The hot / cold water produced by MTA units cannot be used directly for domestic hygiene or food
applications. In the case of such applications, the installer is responsible for fitting an intermediate
exchanger.
If the intermediate exchanger is not fitted, the installer should affix a notice stating “non-drinking water”.

2.2.1
Liquids of the user circuit
The liquids of the user circuit must be compatible with the materials used.
These can be water or mixtures of water and glycol, for example.
The addition of anti-corrosive chemical additives and operating in a pH range between 7 and 8 is recommended.
Even in the case of glycol mixtures, the use of appropriate chemical additives (consult the glycol supplier) is very important
to protect the chiller materials from possible corrosion caused by the chemical degradation to which glycol is subject.
If the liquids of the user circuit contains dangerous substances (e.g. ethylene glycol) is very important to collect any liquid
which leaks because it could cause damages to the ambient.
Furthermore, when the chiller is no longer used, dangerous liquids must be disposed of by firms specialised and authorised
for treating them.
