The following labels are used:
Moving parts: Fan assemblies below bottom shelves. Risk of injuries in case of
contact. Hair and clothes might be catched by the fan.
Burning risk: Electrical Defrost Element, located below bottom shelves. Temperature
of the element during the defrost cycle can increase to a high degree.
Risk of burning in case of direct contact.
Shock hazard: Electrical parts are located below the bottom shelves, which also
functions as an air discharge. Fan motors, defrost element, solenoid and
control valves. Shelf lighting or fan plate assemblies may cause shocks
when working in the interior of the cabinet.
Always switch of the electric power when work is carried out at the

located in the central fuse box in the shop.
For cleaning instructions see chapter 3 Cleaning and maintenance.
In all events:
-Do not spray water in the interior of the counter.
-Do not spray water at the fan assembly and the switchbox/control panel
Field connections:
All connections on the counter, such as electricity, drainage and coolant pipes, must be carried out by

1 Introduction.
Congratulations on your decision to purchase the Market serve-over counter from Smeva. The name
Smeva is your guarantee of quality and reliability.
The Market is a chilled, serve-over counter with open service access, characterises by a variety of
versions.
The counter is designed to display cold pre packed goods. And is not designed to cool down goods.
This counter meets the highest requirements. This does not mean that the counter does not has to be
treated and maintained properly. This manual can help you do this.
A troubleshooting list for minor malfunctions that are easily rectified is also included.
See chapter 6 Minor Malfunction List.
For more serious faults and/or defects in the counter contact your Smeva dealer.

2 Putting the Counter into Service.
For correct operation of the counter, the following instructions should be followed.
2.1 External Influences.
-Avoid placing the counter in direct sunlight.
Thermal radiation can raise the product temperature to an unacceptable level even when the air
temperature display in the counter shows the required value.
-Keep the lighting intensity in the store as low as possible.
By this we mean the extra lighting that may shine onto the display area from outside the counter. No
spotlights should therefore be directed at the display area.
Moreover, light is one of the main causes of discoloration of fresh meat and other products.
-Avoid placing heat-emitting equipment in the immediate vicinity of the counter.
Discuss this with your installers!
Heat sources include radiators, heaters, ovens, heat-emitting machinery, spotlights, air curtains at
entrances.
-Avoid air-disturbing factors, such as air-conditioning units, inlet grilles and fans that will
affect the operation of the counter.
Draughts can cause, excessive temperatures raises!
An open-cooled counter is sensitive to draughts. Therefore, take care, with air heating and extractor
systems. Doors, windows, entrances and exits can also adversely affect the effectiveness of the
counter by causing draughts.
Take the necessary measures to prevent draughts.
__________________________________________________________________6

2.2 Load Arrangement.
Before start to load the counter it must be carefully cleaned and have reached the required
temperature. The serve-over counter is only mentioned for pre-packed goods.
- Make sure that the display is loaded in the right way. Because it can affect the air circulation
and temperature.
- Only load the counter with pre-cooled goods.
- Make sure the goods are not stacked too close together. In this way sufficient air circulation around
the goods is ensured
- Respect the maximum load level. If goods are piled up too high the air circulation will be affected as
well.
- Make sure that the goods are not staged in front of the air discharge at the back, neither on top of the
air return in the front.
- Take care that the openings of the inlet grill are not blocked by products, shelves, doilies, etc.
This can impede air circulation, which in turn may result in unacceptably high product temperatures!

2.3 Control panel / Thermostat.
Based on the product order, the counter is equipped with a various range of control units, types and
fabrics.
Like the service switch, the control unit is located underneath each counter section.
For a detailed description and the operation of these control units, see the separate user’s manual for
the control unit fitted in your counter.
- Temperature settings.
The temperature is normally controlled by the air off temperature . Factory setting Set point at -4°C.
Differential 2 Kelvin.
- Defrost program.
For low temperature applications (< +2°C) the evaporator coil can be fitted with an electric defrosting
element for defrosting the coil.
For higher temperatures the ice will cycle off by the fans only. (with normal store conditions.)
The defrost cycle is started minimum of 4 times each day to defrost the ice on the evaporator coil. The
defrost termination probe located in the coil will start up the cooling again if the maximum defrost
termination temperature is reached before the end of the set defrost length.
Factory settings; 6 defrost cycles each 24 hours.
Cycle off defrost length 45 minutes. Defrost termination temperature +6°C
Electrical defrost length 30 minutes. Defrost termination temperature +8°C
- Thermometer - display.
The temperature displayed is normally the air off temperature from the evaporator coil. During defrost
cycle the temperature will raise for a short period of time.
This will not effect the average temperature off the goods over the entire day.

3 Cleaning Instructions.
BEFORE YOU START TO CLEAN OR WORK ON THE COUNTER MAKE SURE THAT THE
POWERSUPPLY IS SWITCHED OFF!!!
Possible shock hazards from fan plate assemblies etc. may occur if you work in the interior of
the counter.
Based on the product order specification a service switch is located underneath each counter
section. If there is no service switch, please switch of the electrical current by using the switch
located in the central fuse box in the shop.
The exterior of the counter can be cleaned with a damp cloth or with little lukewarm soapy water.
Never use aggressive detergents.
Ensure that (soapy) water can never run into the switch box behind the kick plate!
The interior can be cleaned with warm soapy water and rinse with plenty of water.
Never use aggressive detergents.
If the bottom shelves are moved to clean the base and evaporator area make sure the power is
switched off in order to prevent:
- possible shock hazard
- running fans, moving parts
- hot defrost element
In case of cleaning with detergents, always read the instructions of the used product in advance.
4 General Maintenance Instructions.
It is recommended that you have your counter inspected by a qualified engineer at least once a year.
In addition national regulations may lay down a legally required inspection frequency per year.
During this inspection, attention has to be paid to the setting of the control system and the functioning
of the cooling equipment. The cooling circuit is examined for leakage and the fans are inspected.
Technical cleaning and removal of dust in the evaporator coil and air circulation system.
Cleaning and inspection of the drainage system.
Consult your Smeva dealer regarding maintenance inspections.
5 End of lifecycle, Disassembly, Disposal.
By the development and material choice of the counter, a 15 year lifecycle is considered, depending
on use and circumstances. The counter has a factory warranty of 1 year.
Damage caused by third parties is not covered by the warranty.
Due to abrasion some parts can be replaced during the lifecycle. These are electrical components as
control switches, fan motors, tube lighting. External components as price rails, nose profiles, ect.
The counter can be handed over for revision of technical elements and appearance.
Refrigerated counters decommissioned for disposal must be disposed of in a proper manner. The end
user is responsible for ensuring proper disposal by law.
For disposal purposes, distinction is to be made between
-Operating materials/substances (refrigerant and refrigerator oil or coolant)
-The counter body materials (metals, plastics, polyurethane foam ect.)
-Electronic parts. (controllers, ballast boxes.)
If a counter is getting demolished, all materials/substances have to be transported and disposed by
law of local, present, governmental regulations!
For counter materials see chapter 8 Technical specifications
