Correct maintenance allows the user to maximise
performance levels and operating life and
constantly maintain safety requirements.
Do not spray the appliance with direct jets of
water or high pressure appliances.
When cleaning stainless steel, do not use iron
wool, brushes or scrapers as ferrous particles
could be deposited which, on oxidising, could lead
to rust.
To remove hardened residues, use wooden or
plastic spatulas or abrasive rubber pads.
During long periods of inactivity, spread a
protective layer on all stainless steel surfaces by
wiping them with a cloth soaked in Vaseline oil
and airing the rooms periodically.
! Do not use products which contain
substances which are harmful and dangerous for
personal health (solvents, petrol etc.).
7.3. Extraordinary Maintenance
! Before starting any non-routine maintenance
work, wear suitable personal protective equipment
(protective gloves, safety footwear and mask).
Non-routine maintenance must be carried out by a
qualified professional.
 Periodically have the following operations
carried out by specialised staff:
 Periodically clean the condenser using
suitable tools (suction device or soft
brushes).
 Check the perfect sealing of the door
gaskets and replace them if necessary.
 connections have not loosened.
 Check the efficiency of the heating
element (in BT models).

deactivate connection to the main electrical
line.
2. Clean the appliance and surrounding areas
thoroughly;
3. Spread a thin layer of cooking oil onto the
stainless steel surfaces;
4. Carry out all maintenance operations;
5. Leave the doors ajar to prevent the formation
of mould and/or unpleasant odours.
8.2. Recommendations for normal use
In order to ensure correct use of the appliance, it
is advisable to apply the following
recommendations:
 Do not obstruct the zone in front of the
condensing unit in order to favour heat
disposal from the condenser to a maximum.
 Always keep the front of the condenser clean
using a soft brush and do not use rigid or
metal tools that may damage the condenser
fins.
 Check the planarity of the appliance rest
surface.
 Do not introduce liquid or solid substances at
temperatures above the environmental
temperature and, however, introduce the
material after the appliance has reached the
functioning temperature.
 Do not stack the materials to be preserved in
contact with the internal walls, so blocking the
circulation of air, which guarantees uniformity
of the internal temperature of the refrigerated
compartment.
 Limit the number of times and the duration of
time the doors are open to a maximum.

10. INSTALLATION
10.1. Packaging And Unpacking
Move and install the appliance respecting the
information provided by the manufacturer, shown
directly on the packaging, on the appliance and in
this manual.
The lifting and transportation system of the
packaged product envisages the use of a fork-lift
truck or a pallet stacker, using which particular
attention must be paid to balancing the weight in
order to prevent the risk of overturning (avoid
excessive tilting!).
! ATTENTION: When inserting the lifting
device, pay attention to the gas supply pipe and
the position of the feet.
The packaging is made of cardboard and the
pallet of wood. A series of symbols is printed on
the cardboard packaging which highlights, in
accordance with international standards, the
provisions which the appliances must be subject
to during loading, unloading, transportation and
storage.
On delivery, check that the packaging is intact and
has not suffered any damage during
transportation.
Any damage must be notified to the transportation
company immediately.
The appliance must be unpacked as soon as
possible to check that it is intact and undamaged.
Do not cut the cardboard with sharp tools in order
to prevent damage to the steel panels
underneath.
Pull the cardboard packaging upwards.
After having unpacked the appliance, check that
the features correspond to those requested in the
order;
For any anomalies, connect the dealer
immediately.
! Packaging elements (nylon bags,
polystyrene foam, staples …) must not be left
within reach of children.
Remove the protective PVC film from the internal
and external walls, avoiding the use of metal
tools.
 STACKING LIMITS: Both during transport
and storage the stacking limit of the appliances is
equal to a maximum of 3.

10.2. Installation
! Installation and assembly operations must
be carried out by qualified personnel. If the
equipment uses R290 cooling gas, every possible
precaution must be taken to avoid any danger
linked to the flammability of this gas.
 All the installation phases must be
considered, from the moment of creation of the
general plan.
The installation area must be equipped with all
power supply and production residue drainage
connections and must be suitably lit and respect
current laws regarding hygiene and sanitary
requirements.
To optimise consumption and reduce wear of the
machine, do not position it in the vicinity of heat
sources or in environments where temperatures
are too high.
Proceed with machine levelling, adjusting the
individual feet.
! This appliance can only be installed and
operate in rooms which are permanently
ventilated, in order to guarantee correct operation.
 Connect and leave for a certain period of
time (at least 2 hours) before checking
functioning. During transport it is probable that the
compressor lubricant oil has entered the
refrigerant circuit blocking the capillary: as a
consequence the appliance will function for a
certain period of time without producing cold until
the oil has returned to the compressor.
! ATTENTION: the appliance requires the
minimum functioning spaces as shown in the
diagram.

qualified staff, respecting the current laws
regarding the subject and using appropriate
prescribed material.
 Before connecting the appliance to the
electric mains check that the voltage and the
frequency correspond to the data stated on the
registration plate applied on the rear of the
appliance.
The appliance is supplied with an operating
voltage of 230V 1+N~ 50 50Hz. On request, it is
possible to have appliances with different
voltages.
! Before connection, ensure the presence of a
relevant differential switch with adequate power in
the mains power supply, upstream from the
appliance, in order to protect the appliance from
overloads or short circuits
10.4. Refrigerant Attachment (Remote Version)
The "remote" condensing unit connection must be
carried out according to the attached refrigerator
lay-out.
Remember that the following are present in the
technical compartment:
 Intake pipe.
 Liquid delivery pipe.
These are therefore connected with the
corresponding types present in the condensing
unit.
When the connection has been made, carefully
empty and then load paying attention to use a
type of refrigerant gas that is compatible with the
components present.
For the start-up of the appliance, carry out electric
connections between the instruments
present on the control panel and condenser unit
according to the attached wiring diagram.
10.5. Inspection
The appliance is delivered in conditions that it can
be started-up by the user.
This functionality is guaranteed by passing the
tests (electric inspection - functional inspection,
appearance inspection) and relative certification
through the specific attachments.
