6. HANDLING AND STORAGE (SPECIALIST TECHNICIAN)
6.1 HANDLING
The loading and unloading operations must be performed by qualied sta,
who will verify the exact weights and lifting points; they will use lifting
equipment which is safe and with a suitable carrying capacity. There must be
no individuals who are not involved in the operation close to the lifting points.
Fig. 1
The package must be lifted by inserting
the forks of the lift truck into the space
between the legs of the pallet or crate.
The weight of the equipment must be
divided so that the centre of gravity of
the package remains balanced (Fig.1-A).
Do not tip the equipment over.
PROHIBITED LIFTING MEANS
Lifting means or equipment which do not respond to the safety requirements must not be used.
These include:
• lifting capacity lower than the weight of the equipment;
• unsuitable construction features of the forklift truck (e.g. short forks);
• construction features altered by use;
• non-compliant ropes or cables;
• worn-out ropes or cables.
Any other handling procedure dierent to those described in this
chapter are prohibited.
Before inserting the forks of the lift truck, verify that these cover
the entire depth of the package (Fig. 1-B). If not, install
appropriate extensions.

7. AMBIENT CONDITIONS FOR INSTALLATION
The equipment must be installed in a closed environment, covered
and safe from atmospheric agents.
The equipment must not be installed in areas containing explosive
substances.
25°C
60%
Position the equipment far from draughts (fan-coil,
fans, windows, air outlets).
Avoid exposing the equipment to direct sunlight,
to concentrated light units or to sources of heat
such as radiators, stoves or ovens.
Ensure there is sucient air circulation on all sides
of the cabinet.
It is absolutely forbidden to position objects
around the counter which can in some way hinder
the circulation of air over the condensing unit.
Failure to comply with the above requirements
can, in addition to the fast deterioration of the
materials composing the cabinet, cause poor
operation of the cabinet, including:
• Higher energy consumption.
• Mist formation on the cold surfaces (glazing or countertop).
• Poor preservation of the foods of the counter and the risk of making the displayed goods
deteriorate.
The ambient temperature must fall within the temperature limits established by the class of
equipment (25 °C - 60% of humidity). If these limits are exceeded the performance of the
equipment will be lower.

• Don’t obstruct “B” slot of refrige-
rated air exit.
• Don’t obstruct “C” slot of air inta-

• Don’t obstruct refrigerated air
ow; leave spaces between
product.
• Don’t exceed the admitted load
for the display shelves (see techni-
cal sheet)
For correct operation of the display
cabinet and to reduce energy
consumption, the sliding doors
must remain open for the least
possible time.
If the sliding doors remain closed
for an extended time, condensa-
tion may form in the top part of the
unit.
To reduce this eect, it is recom-
mended to open the sliding doors
to release a little cold air and then
close them again.
To facilitate loading/unloading the goods we recommend opening the front glass.
Do not obstruct air exit and entrance points.

10.3 ACCESSORIES
10.3.1 FRONT ANTI-MIST
The cabinets avail of an anti-condensation ventilation system for the front glass. If the excess
humidity of the environment were to create problems like misting of the crystals, a warning
light switch assembled on the control panel at the back of the cabinet, see gure below, allows
to turn on an anti-mist heating element.
The heating element turns o automatically after an hour of operation (warning light switch
o); if the need to use it persists, press the button again.
The time of operation of the heating element may be varied; in this case, contact your closest
assistance centre who will make the change.

11.1 ESTERNAL CLEANING
Clean all the external parts of the cabinet on a weekly basis, using exclusively warm water and
soap or neutral detergent for domestic use diluted in water. Dry carefully using a soft cloth.
It is forbbiden to use ammable or abrasive products such as alcohol, acetone or
solvents; Do not use detergents that contain non-ionic surfactants, lemon, or vinegar
(acetic acid).
NEVER USE JETS OF WATER TO CLEAN THE CABINET. Use only glass cleaning products to clean
glass surfaces. It is not recommended to use water because it can leave scale deposit on the
glass surface.
CLEANING FRONT GLASS
To facilitate the cleaning operations of the front glass, it is always recommended to open it (lift
it upwards, pull it outwards or to the side, depending on the model of the superstructure).
Be careful not to make force on the upper glass.
11.2 INTERNAL CLEANING
Clean all the internal parts of the cabinet on a monthly basis, following the same indications set
out at the preceding point and using exclusively a non-abrasive sponge. The maximum
water temperature used for cleaning is 65°C.
To clean the internal parts it is also necessary to follow the instructions below:
• De-energise the cabinet using the main disconnect switch on the wall.
• Empty the equipment completely putting the goods into other refrigerators.
• Wait for the equipment to be at ambient temperature.
• Extract the REMOVABLE DRAWER.

• Proceed with cleaning: to clean the area under the evaporator, with the aid of a suitable
recipient, slowly pour some hot water taking care not to splash the surrounding components.
The water must be poured from the rear side so that as it flows, it moves towards the drainage
holes of the tub. If necessary, repeat the operation more times.
• To facilitate these operations and the collection of wash water, a drainage pipe has been pro-
vided to convey the water used for internal cleaning, directly to the outside of the unit.
• After attentively checking that the inside of the cabinet is completely dry, put the appliance
back into operation by reconnecting power to the cabinet.
• After a few hours, load the product again.

Remove the EVAPORATOR-COVER “A”
Be careful not to cut yourself with the thin evaporator ns or with
edges or corners of adjacent sheets.

Any other maintenance work which is not handled in the previous points must
be carried out by service centres authorized by our dealers or by qualied sta.
12.3 MODIFICATION OF ELECTRONIC CONTROLLER SETTINGS
To modify the SETPOINT see the chapter “MODIFACTION OF SET POINT”. The modication of
the parameters, dierent to the SETPOINT, which modify the operation of the cabinet must be
performed solely by the installer or by a qualied technician. The manuals of the electronic
controllers are found at the links below, or they can be requested from the service department
of EUROCRYOR:
http://food-retail.danfoss.com/products/electronic-controllers/evaporator-controllers/
It is recommended to have a specialist technician perform an annual
general check-up of the equipment (gas springs, refrigerator circuit…).
12.1 REPLACEMENT OF LED MODULES
Caution: to replace a LED lighting xture it is obligatory to contact the cabinet dealer.
Do not install alternative components.
12.2 WORK ON PROTECTION SWITCHES
To reactivate the protection switches, access the component chamber (see chapter
“electrical connections”) and turn the switch to ON.
Any maintenance work must be carried out while the equipment is
disconnected from the power source.
Turn o power at the main switch on the wall.
Attention: before accessing the terminals, all the power circuits must be
disconnected.
