2 SAFETY

2.1

Foreword

These units must be installed in conformity with the

provisions of Machinery Directive 98/37/EC, Low

Voltage Directive 73/23/EC, Pressure Vessels Direc-

tive 97/23/EC, Electromagnetic Interference Direc-

tive 89/336/EC, as well as with other regulations

applicable in the country of installation. If these pro-

visions are not complied with, the unit must not be

operated.

The unit must be grounded, and no installa-

tion and/or maintenance operations may

be carried out before deenergising the elec-

trical panel of the unit.

Failure to respect the safety measures mentioned

above may result in electrocution hazard and fire in

the presence of any short-circuits.

Inside the heat exchangers, the compres-

sors and the refrigeration lines, this unit

contains liquid and gaseous refrigerant un-

der pressure. The release of this refrigerant

may be dangerous and cause injuries.

The units are not designed to be operated

with natural refrigerants, such as hydrocar-

bons. Itelco-Industry may not be held liable

for any problems deriving from the replace-

ment of original refrigerant or the introduc-

tion of hydrocarbons.

Itelco-Industry units are designed and manufactured

according to the requirements of European Standard

PED 97/23/EC (pressure vessels).

– The used refrigerants are included in group II (non-

hazardous fluids).

– The maximum working pressure values are men-

tioned on the unit’s data plate.

– Suitable safety devices (pressure switches and safe-

ty valves) have been provided, to prevent any

anomalous overpressure inside the plant.

– The vents of the safety valves are positioned and

oriented in such a way as to reduce the risk of con-

tact with the operator, in the event that the valve is

operated. Anyway, the installer will convey the dis-

charge of the valves far from the unit.

– Dedicated guards (removable panels with tools)

and danger signs indicate the presence of hot

pipes or components (high surface temperature).

The guards of the fans (only for units pro-

vided with air heat exchangers) must be al-

ways mounted and must never be removed

before de-energising the appliance.

It is the User’s responsibility to ensure that

the unit is fit for the conditions of intended

use and that both installation and mainte-

nance are carried out by experienced per-

sonnel, capable of respecting all the recom-

mendations provided by this manual. It is

important that the unit is adequately sup-

ported, as detailed in this manual. Non-

compliance with these recommendations

may create hazardous situations for the

personnel.

The unit must rest on a base which meets

the characteristics specified in this manual;

a base with inadequate characteristics is

likely to become a source of serious injury

to the personnel.

The unit has not been design to withstand

loads and/or stress that may be transmitted

by adjacent units, piping and/or structures.

Each external load or stress transmitted to

the unit may break or cause breakdowns in

the unit’s structure, as well as serious dan-

gers to people. In these cases, any form of

warranty will automatically become null

and void.

The packaging material must not be dis-

posed of in the surrounding environment or

burnt.
