Periodical Maintenance - Diamond VA10/R2 Manual De Installación E Instrucciones Para El Uso

The necessary operations are:
1) Verify that the power supply voltage is as indicated on the machine rate plate
(fig. C) 230V/50 Hz monophase, or 220V/60Hz or 110V/60Hz.
2) In case of incompatibility between the socket and the plug of the
unit, the plug should be replaced with a suitable one by a qualified
technician. Do not use adapter sockets.
3 ) Do not connect any other appliance to the same power socket.
4) Do not pull the electrical cable or the unit to unplug the equipment from the
socket (fig. E).
5) Pay attention that the power supply cable is laid in such a way as to prevent it
from being damaged or becoming hazardous to people and things.
6) In case the power supply cable is damaged, it should be replaced only by a
qualified technician.

8) PERIODICAL MAINTENANCE

We suggest to carry out a thorough cleaning of the counter once a month
for the good working, the good preservation of the food and the aesthetics
preservation of the equipment. The periodical cleaning can be made by qualified
people, who should know the procedure described in this paragraph. Attention!
Before starting any cleaning operation it is necessary to turn off the
equipment by the on/off red switch (see picture I/L) and to unplug or
disconnect the equipment by the general power security switch of your shop.

II TO PROTECT YOUR HANDS ALL THE TIME.
Remove all goods from the refrigerated unit and keep them in a fridge or in a
refrigerated ambient suitable for their preservation.
Carefully and thoroughly clean the display surface, the glasses, the aluminium
profiles with specific cleaners for any surface. Never use abrasive substances,
metal pads or other stuff which can damage the unit.
After every cleaning operation it is necessary to rinse with warm water and dry
the unit with a soft cloth.
Clean the condenser, after having removed the cover grid, with a dry paint brush
(fig. H) or a vacuum cleaner, removing all dust. Pay attention not to bend or
damage the fins, the tubes or the blades of the fans. When you have finished this
operation, fit the cover grid in its original position.
When the cleaning operation is over, make sure that everything is clean and
dry before connecting the equipment to the power supply again. When the unit
reaches the correct working temperature, it is possible to reload it. In case of
long absences (i.e. holidays etc.) the unit has to be unplugged, emptied completely,
cleaned and dried to prevent bad smells.
9) DEFROSTING
The defrosting for the VR 2000 and VR 2005 takes place automatically during the
running of the unit. The defrosting cycles are 4 a day and last for about 30' each.
For the VR 70 and VR 2002 the defrosting will have to be made by the user by
switching off the unit by the ON/OFF switch, because these models are not
equipped with timer.
During the defrosting phase the temperature of the unit could be altered, but
when this cycle is over, in a short time the working temperature will return to
normal.
The water from defrost in the models VR 2000 – VR 2005 – VR 2002 is collected
in a drip tray with hot-gas pipe that will allow the evaporation of the water. The
model VR 70 is not equipped with a water drip tray and it must be connected to
an external drain-pipe.

10) ELECTRONIC THERMOSTAT FOR THE MODELS VR 2000 AND
VR 2005
TEMPERATURE MODIFICATION
The thermostat is already set at the factory. In case the temperature is altered,
the manufacturer will not take any responsibility. Any modification will have to be
made by qualified people.
• Press for 5 seconds to display the selected parameter value; press
reach the required temperature;
• Press to confirm.
11) TEMPERATURE
The thermostat regulates the temperature into the equipment and the working
temperature is already preset at the factory.
A lower performance must be expected from the refrigerated unit when:
- the equipment is set on the lowest temperature
- the equipment is positioned in an ambient with higher temperature or relative
humidity than above indicated
- the amount of displayed goods exceeds the maximum recommended and the
proper air circulation is prevented.
In those cases the goods are kept at higher temperatures, the refrigerating unit
has to run non-stop and ice may form on the evaporator. It is necessary therefore
to turn the equipment off to allow the complete melting of the ice.
12) TECHNICAL ASSISTANCE (servicing)
If the equipment does not run properly or does not work at all, in your own
interest before calling for servicing, we suggest to check the following points:
1) if the plug is well inserted in the socket;
2) if the power reaches the socket to which the equipment is connected;
3) if the thermostat is set as recommended;
4) if the network voltage is the same as requested for the unit (+-6%);
5) if the evaporator is covered with ice (in this case proceed as indicated at
paragraph 11);
6) if the condenser is clean;
7) if there are air draughts, if the cabinet is installed in the correct position (see
paragraph 5) and if the ambient temperature is as indicated (see paragraph 4).
13) REPLACEMENT OF LAMPS (neon tube)
The replacement and the substitution of lamps must be made by qualified
technician and when the unit is disconnected from the power net. Disconnect
the main power supply before fitting or replacing the lamp. Slip the ring nuts onto
the fluorescent lamp. Fit the lamp in the lamp holder and turn it 90°. Slide the ring
nuts along the lamp until they rest on the lamp holder and turn them clockwise
(NPP and NPQ); screw down tightly (NPW).
