a fire the temperature of the refrigerant could reach values that
increase the pressure to beyond the safety valve with the
consequent possible projection of the refrigerant itself or
explosion of the circuit parts that remain isolated by the
closure of the tap. Do not remain in the proximity of the safety
valve and never leave the refrigerating system taps closed.
Electric parts
An incomplete attachment line to the electric network or with
incorrectly sized cables and/or unsuitable protective devices
can cause electric shocks, intoxication, damage to the unit or
fires. Carry out all of the work on the electric system referring
to the electric layout and the present manual ensuring the use
of a system thereto dedicated. An incorrect fixing of the electric
components cover may favour the entry of dust, water etc
inside and may consequently can electric shocks, damage to
the unit or fires.
Always fix the unit cover properly. When the metallic mass of
the unit is under voltage and is not correctly connected to the
earthing system it may be as source of electric shock and
electrocution.
Always pay particular attention to the implementation of the
earthing system connections. Contact with parts under voltage
accessible inside the unit after the removal of the guards can
cause electric shocks, burns and electrocution.
Open and padlock the general isolator prior to removing the
guards and signal work in progress with the appropriate shield.
Contact with parts that could be under voltage due to the start
up of the unit may cause electric shocks, burns and
electrocution.
When voltage is necessary for the circuit open the isolator on
the attachment line of the unit itself, padlock it and display the
appropriate warning shield.
Moving parts
Contact with the transmissions or with the fan aspiration can
cause injuries. Prior to entering the inside of the unit open the
isolater situated on the connection line of the unit itself,
padlock and display the suitable sign.
Contact with the fans can cause incurie.
to removing the protective grill or the fans, open the isolator on
the attachment line of the unit itself, padlock it and display the
appropriate warning sign.
Refrigerant
The intervention of the safety valve and the consequent
expulsion of the gas refrigerant may cause injuries and
intoxication. Always wear suitable clothing including protective
gloves and eyeglasses for operations inside the danger zone.
Should the gas refrigerant leak please refer to the refrigerant
"Safety sheet".
Contact between open flames or heat sources with the
refrigerant or the heating of the gas circuit under pressure (e.g.
during welding operations) may cause explosions or fires.
Do not place any heat source inside the danger zone.
The maintenance or repair interventions which include welding
must be carried out with the system off.
Hydraulic parts
Defects in ducting , the attachments or the cut-off parts may
cause a leak or water projection with the consequent damages
to people, things or shortcircuit the unit.
Disconnection
Only authorised personnel must disconnect the unit.
Avoid leak or spills into the environment.
Before disconnecting the unit, the following must be
recovered, if present:
- refrigerant gas
- Anti-freeze solutions in the hydraulic circuits
When awaiting dismantling and disposal, the unit can also be
stored outdoors, as bad weather and rapid changes in
temperature will not cause damage to the environment, if the
unit's electric, cooling and hydraulic circuits are integral and
closed.
CE WEEE DIRECTIVE
The units covered by the legislation in question are marked
with the symbol on the side.
With the aim of protecting the environment, all of our units are
produced in compliance with CE Directive on waste electrical
and electronic equipment (WEEE).
The potential effects on the environment and on human health
due to the presence of hazardous substances are shown in
the use and maintenance manual in the section on residual
risks.
Information in addition to that indicated below, if required, can
be obtained from the manufacturer/distributor/importer, who
are responsible for the collection/handling of waste originating
from equipment covered by CE-WEEE. This information is
also available from the retailer who sold this appliance or from
the local authorities who handle waste.
CE-WEEE directive requires disposal and recycling of
electrical and electronic equipment as described therein to be
handled through appropriate collection, in suitable centres,
separate from collection for the disposal of mixed urban
waste.
The user must not dispose of the unit at the end of its life
cycle as urban waste. It must instead be handed over to
appropriate collection centres as set forth by current
standards or as instructed by the distributor.
If disposal takes places at the same time as delivery of a new
electrical or electronic equipment for the same family, the
product may be collected directly by the distributor.
Dismantling and disposal
THE UNIT MUST ALWAYS BE SENT TO AUTHORISED
CENTRES FOR DISMANTLING AND DISPOSAL.
When dismantling the unit, the fan, the motor and the coil, if
operating, may be recovered by the specialist centres for
reuse. All the materials must be recovered or disposed of in
compliance with the corresponding national standards in
force.
For further information on the decommissioning of the unit,
contact the manufacturer.
