1 SAFETY RECOMMENDATIONS

When installing and using the unit please follow the recommendations listed here below.
• Installation shall be carried out in strict compliance with the diagrams and instructions supplied by the manufacturer.
• Damages due to improper connections are excluded.
• The electric system available where the unit is installed shall meet the relevant standards in force.
• Maintenance shall be effected by trained personnel or by the manufacturer according to the provisions supplied by EN378.
WARNING
Use safety gloves to protect your hands from possible cuts.
The user is strongly recommended to contact the manufacturer before attempting any intervention on the unit and
any use not corresponding to the manufacturer's indications (in particular as for the field of application) and to enquire about
the possible dangers and contra-indications connected with an improper use of the machine.
• The unit shall be used following these instructions and sticking to the destination of use indicated by the supplier. Any
incorrect use can result in damages to the unit and represents a serious danger for people's health.
ATTENTION
The unit is not suitable for working in explosive environments.
Therefore the use of the unit in an explosion-dangerous atmosphere is absolutely forbidden.
When maintenance requires operations on the cooling circuit, drain the system and let it reach the atmospheric
pressure. Oil residuals left in the refrigerant receiver should be recovered and disposed of by specialized firms, specially
authorized by the national regulations in force.
ATTENTION
The unit is not suitable for working in salty environments. In such a case protect condenser and
evaporator with appropriate means.
WARNING
Do not discharge the refrigerant in the atmosphere. It must be recovered by specialized technicians
using suitable equipment.
• Quantity and quality of the refrigerant to be charged are indicated on the data plate.
• Do not use refrigerants of different kind (especially inflammable fluids, for example hydrocarbons) or air.
• No modifications or changes in circuit or components (such as: welding on compressor body, on refrigerant receiver wall or
on refrigerant separator wall) are allowed.
• Glass windows, minimum level indicators and flanged couplings are secured to the receiver or the separator by means of
demountable fixing elements. As a rule, gaskets resist pressure, temperature and fluid stresses. When fixing elements
include gaskets (for example glass windows and flanges) however, reduced tightness and bedding of gaskets can not be
excluded due to their features; for this reason tighten them before and possibly after starting. Driving torques can be
different. On glass windows (mounted on refrigerant receiver) use a dynamometric wrench, otherwise the steel edge could
be excessively loaded and cause glass breakage.
• Any official registration necessary for pressure appliances and repeated tests shall by governed
regulations in force in the Country where the unit is installed. Compliance with laws, regulations and with the technical
instructions specified above falls within the manager's responsibility.
• The final user shall protect the unit from external fire dangers.
