25. 1

DISCONNECTING THE UNIT

The unit disconnection operations
must be carried out by a registered
technician.
Before disconnecting the unit, the fol-
lowing elements must be removed, if
present:
• The refrigerant gas: the gas must
be removed with suction devices
that operate in closed circuit so that
there is no gas leak in the environ-
ment.
• The glycol must not be thrown away
in such a manner that affects the
environment when it is removed. It
must be placed in suitable contai-
ners.
The device is designed and built to en-
sure the maximum safety in its imme-
diate vicinity (IP24) as well as to resist
atmospheric agents.
26. 1 IMPORTANT SAFETY
INFORMATION
The machine must not exceed the pres-
sure and temperature limits indicated
in the table shown in the Operating
limits" section.
Correct functioning is not guaranteed
after a fire; before starting up the ma-
chine again, contact an authorised As-
sistance Centre.
The machine is fitted with safety valves
that in the case of excessive pressure
can discharge hot gases into the atmo-
sphere.

DISPOSAL

25
NOTE
The disposal of refrigerant gas, the
glycol water that may be present and
any other material or substance must
be carried out by qualified personnel
and in compliance with the legisla-
tion in force, in order to avoid causing
damages to things or people as well as
polluting the surrounding area.
When the unit is pending disposal,
it can also be stored in the open, as
exposure to the elements and tempe-
rature changes do not cause harmful
effects for the environment, as long as
the unit electrical, cooling and hydrau-
lic circuits are closed and in good con-
ditions.

INCORRECT USE

26
Wind, earthquakes and other natural
phenomena of exceptional intensity
have not been
taken into account.
If the unit is used in an aggressive at-
mosphere or with aggressive water,
consult the company headquarters.
CAUTION
Following extraordinary maintenance
interventions on the cooling circuit,
with the replacement of components,
before restarting the machine it is ne-
cessary to carry out the following ope-
rations:
- Pay the greatest attention when re-
storing the refrigerant load indica-
ted on the machine rating plate.
- open all the taps in the cooling cir-
cuit
25.2 DISMANTLING AND
DISPOSAL
In the dismantling phase, the fan, the
motor and the coil, if operating, could
be taken from the specialised centres
for possible reuse.
NOTE
For lo dismantling/disposal, all the
materials must be sent to the autho-
rised centres in compliance with the
national regulations in force. For fur-
ther information on discharge contact
the head office.
- correctly connect the power supply
and the earthing
- Check that the coil is not dirty or ob-
structed
CHECKS IN THE SYSTEM
- Check the hydraulic connections in
the entire system
- Check the water pump is working
