12. 1

Disconnecting the unit

The operations for disconnecting the
unit must be carried out by a qualified
technician.
Before disconnecting the unit, the fol-
lowing must be recovered, if present:
• Refrigerant gas: the gas must be
extracted using suction devices ope-
rating in a closed circuit to ensure
there are no gas leaks into the envi-
ronment.
• The glycol must not be dispersed in
the environment when removed, but
stored in suitable containers.
The appliance is designed and construc-
ted to guarantee the maximum safety
in its immediate vicinity (IP24), as well
as to resist atmospheric agents.
The fans are protected from involun-
tary intrusion by means of protective
grilles.
Accidental opening of the electrical
switchbox with the machine in opera-
tion is prevented by the door-blocking
disconnector switch.
Avoid laying tools or heavy objects di-
rectly on the lateral heat exchange bat-
teries, in order not to damage the fins.
NOTE
Do not insert or drop objects through
the grilles of the fan motors. Do not
lean against the heat exchange batte-
ries: "Sharp surface".

12 DISPOSAL

NOTE
The disposal of the gas refrigerant,
the glycol/water mixture where pre-
sent, and the recovery of any other
material or substance must be carri-
ed out by qualified personnel in com-
pliance with the specific regulations
in force to prevent damage to per-
sons or things as well as the pollu-
tion of the surrounding area.
While waiting for disposal, the unit can
be stored outdoors, as harsh wea-
ther conditions or extreme tempera-
ture changes do not cause damaging
effects on the environment provided
that the electrical, cooling, and hydrau-
lic circuits are intact and closed.

INFORMATION
The machine must not exceed the pres-
sure and temperature limits indicated
in the table shown in the section "Limits
of operation" of the technical manual.
Correct operation of the unit is not gua-
ranteed following a fire; before restar-
ting the machine, have it checked by an
authorised service centre.
The machine is equipped with safety
valves that, in the event of excessive
pressure, can discharge the high tem-
perature gas into the atmosphere.
Wind, earthquakes, and other natural
phenomena of exceptional intensity
have not been considered.
In the case that the unit is used in an
aggressive atmosphere or with ag-
gressive water, please consult with the
manufacturer.
