Tampering with or unauthorised replacement of one or more parts of the equipment, applying accessories that modify its use and fi tting spare parts other than recommended ones may result in
accident risks.
Danger
Before doing any type of work, the equipment must always be disconnected from the power supply.
Any work on electric parts or cooling system components should only be carried out by
trained personnel in compliance with current laws.
2.1 Personnel training

Attention
The equipment is intended for professional use.
2.2 Safety devices applied
The Equipment is equipped with the following safety devices:
2.2.1 SAFETY DEVICES PRESENT
2.2.2 FIXED PROTECTIVE DEVICES
2.2.3 SECTIONING THE ELECTRICITY SUPPLY
2.2.1 Safety devices present
Devices which operation prevents risk situations in operation conditions verifying (e.g.
fuses, pressure switches, protective devices, circuit breakers, etc.).
2.2.2 Fixed protective devices
Fixed protective devices consist of fi xed perimeter shields, which are used to prevent
external parts from entering the equipment.

2.2.3 Sectioning the electricity supply
Before conducting any maintenance work on the equipment or part of it, it is necessary to
section the power supply that powers it.
Danger
Please remember to fully disconnect the equipment from the power supply in the event of maintenance
work during which the operator cannot prevent any accidental closure of the circuit by other people.
2.3 Residual risks
During design the manufacturer examined all the areas or parts at risk. Therefore, all
necessary precautions have been taken to prevent risks to persons and damage
to the equipment as mentioned earlier.
Attention
Periodically check that all safety devices are operating correctly.
Do not remove the fi xed protective devices.
Do not introduce foreign objects or tools into the operational and working area.
Although the equipment is fi tted with the aforementioned safety devices, there are still
some risks that cannot be eliminated, but reduced via corrective actions by the fi nal
integrator and correct operational procedures.
Below is a summary of the remaining risks associated with the equipment during:
- Normal operation
- Adjustments and tweaking
- Maintenance
- Cleaning
2.3.1 Risk of contact with live parts
Risk of breaking or damaging the electrical components of the equipment, with a possible
reduction in safety levels, following a short circuit.
Before connecting the electricity supply, make sure there is no ongoing maintenance work.
Attention
Before making the connection, check that the d/c electricity at the point of installation is no higher than
the value indicated on the protective switches on the fuse box. if it is, the user is responsible for fi tting
the relevant limiting devices.
It is strictly forbidden to conduct any electrical modifi cation, in order to prevent additional unforeseen
hazards and risks.
2.3.2 Fire
Danger

2.3.3 Explosive atmosphere
The equipment must not be located in an area classifi ed as an explosion risk according to
1999/92/EC such as:
Zone 0
An area in which there is a permanent, long-lasting or frequently explosive atmosphere
made up of a mixture of air and fl ammable substances in the form of gases, fumes or
steam.
Zone 1
An area in which the formation of an explosive atmosphere, made up of a mixture of air and
fl ammable substances in the form of gases, fumes or steam is occasionally probable during
normal activities.
Zone 20
An area in which there is a permanent, long-lasting or frequently explosive atmosphere in
the form of clouds of combustible dust in the air.
Zone 21
An area in which the formation of an explosive atmosphere in the form of clouds of
combustible dust is occasionally probable during normal activities.
2.3.4 Slipping

2.5 Refrigerant R290
This equipment contains a small amount of R290 refrigerant, an environmentally
compatible gas, but one that is highly fl ammable. Be very carefully during transport,
installation of the equipment and disposal to not damage the refrigerant circuit pipes.
Maintenance must be performed by qualifi ed personnel who have been trained and
authorised to work with fl ammable refrigerants.
IN THE EVENT OF DAMAGE:
Keep the equipment far from fl ames or sources of ignition. Ventilate the room for several
minutes. Turn the equipment off and disconnect the power supply cord. Inform customer
service. The more refrigerant the equipment contains, the bigger the room must be where
the equipment is installed. In rooms that are too small, a fl ammable mixture of air and gas
can form in the event of leakage. The volume of the room where the equipment is
located must be at least 19 m³ for each chiller system present.
USE:
Never use electrical equipment inside this equipment. Do not damage the refrigerant
circuit. Do not use mechanical devices or other means to accelerate the defrosting process
other than those recommended by the manufacturer. Keep the ventilation openings in the
equipment housing or structure free of obstructions.
DANGER OF EXPLOSION:
Do not store products containing combustible gas propellents and explosive substances
inside the equipment.
INSTALLATION OF THE EQUIPMENT:
A dry, ventilated area is best for installation. The installation area must not be exposed
to direct sunlight and must not be near heat sources such as stoves, heaters, etc. If
installation next to a heat source is unavoidable, use a suitable insulating panel.
ELECTRONIC CONTROL UNIT:
The set-up for refrigerant R290 control unit must only be replaced with ISA supplied
original spare part.
