5.USE AND LIMITS
Each unit is designed for a determined range of temperatures.
The serve over counters are prepared to conserve fresh products or pre-cooked, foods, as well as the
refrigeration of drinks. The temperature must be selected considering the following points:
• Type of product for refrigeration or conservation
• Ambient temperature
• Frequency of which the doors are opened.
Although it is possible to select or reprogram the temperature by manipulating the thermostat, it is not
advisable, as this may cause the improper operation of the unit, changing the purpose for which it was
programmed, and for this reason such manipulation should never be done.
The user of this unit will be responsible for the damage caused to it through non-compliance with the
observation described in the above point.
The units designed for the storage of frozen foods are suitable for the conservation of frozen foods and not
for freezing the product. The environmental operational limits established for the units are shown by
climatic category:
6.RECOMMENDATIONS
• You are recommended to wait until the chamber reaches its operational temperature before introducing
any product.
• In order to obtain better performance, avoid the introduction of hot foods as well as drinks that are not in
sealed packages.
• Protect foods and their odours by using some hermetic closing system, placing them in the unit in such a
way that allows for a good circulation of air, respecting the maximum load indicated on the inside of the
unit.
• Avoid as far as possible the frequent opening of doors and above all, do not leave the doors open.
• Avoid placing sheets of cardboard or paper on the perforated shelves as these will obstruct the circulation
of air.
• The maximum weight for the glass shelf is 8 kg/m, distributed evenly and 60kg/m for shelf exposure.

7. PRECAUTIONS
• The stability of the unit is guaranteed, even when the doors are open, however leaning on the doors is
completely prohibited.
• Do not modify the specifications plate or instructions issued by the manufacturer. • Do not touch the unit
with wet or damp hands and feet.
• Do not touch the unit when barefoot.
• Do not pull the cable to unplug the unit.
• Avoid the use of adapters, extension leads or multiple plugs.
• Before carrying out any cleaning or maintenance operation, unplug the unit from the electricity supply,
first turning off the main switch and then unplugging the unit.
• The unit must not be used by children, persons whose mental, sensory or physical capacities are impaired.
Persons who lack experience or knowledge must be supervised or given instructions for use.
8. MAINTENANCE
Before carrying out any cleaning operation, disconnect the unit from the power supply and place the main
switch in the OFF position.
The units are equipped with a drainage outlet to make cleaning easier, as well as allowing for the eventual
seepage of liquids from the foods. During cleaning, the drainage outlet cover has to be removed and cleaned
in order to avoid being blocked by solid elements being pulled into it.
The good operation and performance of the unit will largely depend on its correct maintenance, carried out
periodically.
The manufacturer is exempt from all liability arising from non-compliance with the procedures contained in
this manual.
• CONDENSER
The incorrect maintenance and lack of cleaning of the gas condenser of the refrigerated unit can
considerably reduce the performance of the unit as well as shortening the life of the compressor motor.
The cleaner the unit, especially the condenser fins, the greater the energy saving.
In any event, it is recommended that this task is carried out by a service technician. In the case of any
doubt, please contact your distributor.
We recommend that this operation is carried out at least once every three months and at the start of
every summer.
Page 11
Pentland Wholesale: 01254 614444 Email: [email protected]
• EVAPORATORS
Only for specialist personnel
The only maintenance the evaporators require is proper cleaning. This has to be done with the machine
stopped and once the ice that may be present on the fins has melted or once defrosting has been done by
operating the controls. This process may be accelerated by using warm water, NEVER using hard or sharp
objects.
In order to clean the coil or the casing, DO NOT use chemical de-greasers with acid compounds or bleach,
chlorine, ammonia or salts as all these products aggressively attack copper and aluminium. Only water with
well-diluted neutral detergents should be used or products especially designed for cleaning the evaporators
of refrigerated units. The cleaner the unit, the greater the energy saving.
• AUTOMATIC EVAPORATION TRAY
Only for specialist personnel
The majority of the units are equipped with an automatic evaporation tray for the situations where an external
outlet is not available to collect the defrosted water from the evaporators. If this tray is not included, the
drainage tubes have to be connected directly to the appropriate device or a receptacle should be positioned
in order to collect the water.
The defrost water can also cause breakdowns as the piping that brings the heat necessary for the water to
evaporate can be punctured or the electrical resistance can deteriorate.
The duration and number of defrosts the refrigerating equipment is regulated at the factory. The user should
not change this regulation.
Attention should be given to this tray and regular cleaning is recommended.
• DOOR SEALS
The rubber door seals are designed to ensure the closure of the doors to the cold chambers and to guarantee
the sealing of the doors against external elements.
A magnetic strip is housed on the inside of the rubber seal, which adheres it to the frame of the unit. Over
time granular particles can become stuck in the seal due to the effect of the magnet and these can rust and
cause stains.
It is recommended that these door seals are kept free from foreign bodies that can cause rust, as well as fatty
deposits which, over a long period of time, can affect the rubber of the door seal.
Clean them with water, using neutral soap and a damp cloth. DO NOT USE DETERGENTS OR ABRASIVE
PRODUCTS.

9. OPERATIONAL TEST
• CHECKS IN THE EVENT OPERATIONAL FAILURE In some situations, operational failure can arise due to
simple causes that users themselves can solve, which is why prior to requesting the intervention of a
specialised technician, we recommend that you carry out the following checks.
The appliance does not work:
- Check that it is correctly plugged in.
- Check that electricity reaches the power outlet.
- Check that general switch is in the I/ON position.
The internal temperature is too high:
- Check that there is no heat source nearby.
- Check that the grill is not obstructed. - Check the Set-point.
- Check that the product loaded is perfectly distributed, without blocking the interior air ventilation exits and
that the time elapsed since loading has been sufficient to chill the products.
- Check if the evaporator has ice.
- Check that the condenser is not obstructed.
- Check that the appliance is functioning normally.
In the event of strange or excessive noises:
- Check the levelling of the unit as this may cause vibrations.
- Check that there is no object rubbing against any movable element of the refrigerated unit.
• NOISE TESTING
- The noise tests were performed in a room without any noise absorption elements and without any large
item placed near to the refrigerated unit.
