IMPORTANT RECOMMENDATIONS
The installation of this equipment should be entrusted to technicians
approved by the vendor and in compliance with standards and rules in force.
Before installing the unit ensure that the circulation and volume of air are
sufficient to allow normal cooling of the condenser and compressor.
Avoid installing the cabinet near major sources of heat or in direct sunlight.
Note that too high an ambient operating temperature can reduce
performance.
When connecting electrically “earth” continuity must be maintained between
the unit and the supply socket.
For cabinets supplied with a supply cable note that this is a specific part and
should only be replaced with an original part. Being considered as a circuit-
breaker, ensure that the plug is easily accessible as a means of electrical
isolation.
Protection against electrical overload or faults is the responsibility of the
installer. Ensure that a circuit breaker or fuses are fitted in the supply circuit
(See Name plate).
All operations on the electrical or refrigeration circuits, including cleaning
operations should only be undertaken with the unit DISCONNECTED
(unplugged socket).
The air-cooled compressor condenser must be cleaned regularly (every 3 to
6 months).
The unit should not be sprayed or splashed with water:
- Do not use a jet wash on the exterior or technical parts of the unit.
- The equipment must not be installed in the open air or exposed to the
elements.
During any intervention it is imperative that the factory systems are respected
so as not to compromise safety.
The correct operation of this equipment depends on the safety and operating
systems functioning as designed in the factory. We cannot be held responsible
for poor operation that results from inappropriate modifications.
The manufacturer can not be held responsible for usage other than that for
which the equipment was designed.

The nameplate is to be found fixed on the bottom right of the cabinet.
For all correspondence relating to your equipment remember:
- The unit code (Type)
- The serial number (N° SERIE)
- The date (Date)
The main characteristics are repeated on a label fixed to the left hand internal panel.
3. INSTALLATION
3.1 GENERAL REQUIREMENTS
The installation, any repairs or alterations to this equipment should be undertaken by
qualified specialists according to good practice.
3.2 HANDLING
Handling must be carried out with adapted lifting devices.
If you have to carry the appliance, use the pallet of origin and in no case can it be
stacked on other appliances.
When transferring the appliance and in the absence of its pallet, the appliance must be
carried and not pulled.
3.3 UNPACKING AND INSTALLATION
3.3.1 UNPACKING
After having cut strapping (only for 10- and 13-level assemblies), remove the plastic film
with cardboard corners and the polystyrene protective bands.

Lift the appliance to pull out its wooden pallet and install the assembly.
Level the equipment with the screw jacks. Note that door alignment may be adjusted by
adjusting the screw jacks of the front legs.
Install the drip tray.
3.3.2 INSTALLATION
When choosing a place for installation, make sure that air circulates sufficiently around
the appliance to allow for proper cooling of the condenser and compressor.
Leave a space of about 5 to 10cm between the walls and the unit.
Avoid the vicinity of a source of heat.
3.4 CONNECTIONS (See § 1 "Technical characteristics")
3.4.1 REFRIGERATING
Supplied fully pre-equipped with connected refrigerating unit and ready to operate, the
appliance does not need any particular refrigerating connection.
As a semi-equipped variant without compressor unit, the appliance is delivered with a
thermostatic regulator (positioned inside the evaporator housing), the suction tubes and liquid
line out in the technical housing.
3.4.2 ELECTRICS
The appliance is supplied with a supply plug that must in no case be removed.
Continuity of the earth circuit is imperative (see § important recommendations).
A circuit-breaker or protective fuses is to be installed by the installer.
As a semi-equipped variant without a compressor unit, the external compressor unit can
be supplied directly from the compressor unit contactor located on the electric plate of the
appliance.
For the semi-equipped appliance 12/6 without compressor unit, it is necessary to
include an external contactor with a coil supplied from the terminals 4 and 22 of the
appliance.
3.4.3 WATER FROM DEFROST
The appliance is supplied with a drip tray for recuperation water that must be emptied
regularly.
This drip tray can be replaced by a direct evacuation to waste (with a siphon to be
designed by the installer).

4. COMMISSIONING
4.1 GENERAL REQUIREMENTS
Check that no foreign body obstructs the evaporator and condenser ventilators. If the
appliance was laid flat during transportation, wait 24 hours before putting it in service so as to
allow oil to return from the refrigerating circuit to the compressor pan (housing).
Install the grid runners on the racks.

4.3 CONFIGURATION OF ELECTRONIC CARD
4.3.1 PARAMETER CONFIGURATION
The assembly is factory-delivered with standard configuration, designed to meet most
current utilizations (see § 1.2, page 3 of the user’s manual). As necessary, this configuration
can be changed.
The modifications of the parameters are definitively taken into account even after the
assembly is switched off.
4.3.2 PARAMETER CONFIGURATION
When the appliance is switched on, press keys 1 and 2 simultaneously for 5 seconds to
access parameter programming. Parameter P01 is displayed.
To move from one number to another, depress key 2 or 1.
To display a pre-adjusted parameter in a number, depress key 3 and actuate keys 2 or 1
simultaneously to modify it. Release key 3 to move automatically to the following parameter.
Programming is left automatic when neither key is actuated for 5 seconds.

The display indicates the type of error.
SAFETY AND UTILISATION
cE = Indicates a communication problem between the display card and the power box.
dEF = Indicates a defrost cycle in progress;
rEG = Indicate that the cycle has not progressed according to regulation.
One of key depressed deletes the message.
FAULTY FUNCTIONING
E1 = Faulty skewer probe –In case of a faulty skewer probe, it is always possible to use
the appliance in timer mode.
E2 = Faulty ambient probe.
The sound alarm can be switched off by depressing any key.
As regards a cycle in progress restarted after a sudden stop in one of the following cases:
. Current switched off during a refrigeration or freezing cycle:
Power cut duration unknown when the supply returns, the regulator switches to the
conservation mode and displays rEG
. Current switched off during a conservation cycle:
At end of power cut, the regulator carries on its conservation cycle
