Service Manual
English
cod. 272631 − rev. 25.02.2005
Caution
We recommend that:
S the manual is retained for the entire service life of the machine;
S the user reads the manually carefully before carrying out any operations on the machine;
S the control is used exclusively for the purpose for which it is intended; incorrect use of the control shall release the manufac-
turer from any liability.
This manual has been prepared to enable the end−user to carry out only the operations that can be made with the panels closed.
Any operations that require the opening of doors or equipment panels must be carried out only by qualified personnel.
Each machine is equipped with an Electric Insulating device which allows the operator to work in conditions of safety. Switch off
the machine before any maintenance operation to eliminate risks remaining (electric shocks, scalds, automatic restarting, moving parts and remote control).
For "UNDER" units installed on raised floor: switch off the machine before removal of the floor panels within a distance of
850 mm from the machine, to avoid risks of contact with rotating devices.
The panel key supplied with the unit must be kept by the person responsible for maintenance.
For identification of the unit (model and serial no.) in case of the necessity for assistance or spare parts, locate the identification
label on the outside of the unit.

1.1 − Inspection
On receiving the equipment immediately check its
condition; report any damage to the transport company at once.
1.2 − Handling
S Always keep the unit vertically upright and do not
leave it out in the open.
S If possible transport the unit using a fork lift truck;
otherwise use a crane with belts or cables, avoiding
pressing on the top edges of the packing.
1.3 − Operating limits
The units are designed to operate within working
ranges (see Tab. 1).
These limits are referred to new machines or to those
that have been correctly installed and serviced.
The warranty clauses are no longer valid for any possible damage or malfunction that may occur during or
due to operation outside the application values.
1.4 − Identification
The air conditioner can be identified according to the
following nomenclature:
