Each cabinet has a one (1) year durability and material warranty for normal ambient conditions
(class 3).
Normal ambient conditions must not exceed:
• Relative humidity 60 % RH
• Ambient temperature +25 °C

2. Set the cabinet in its place.
Leave an unobstructed air gap of at least 8 cm behind the
cabinet, also when cabinets are back to back, and of at least
25 cm above the cabinet.
3. Adjust the cabinet to stand perpendicularly using the adjustable legs.
4. Ensure that the airow to the condenser unit is not obstructed.
When installing the cabinet, make sure of the following:
• The area where the cabinet is placed is at and level.
• No objects are placed on top of the cabinet.
• The cabinet is not placed in the immediate vicinity of a heat source
such as a radiator, warm air blowing heater or spotlight.
• The cabinet is not exposed to direct sunlight. If necessary, use blinds in
any nearby window.
• The air conditioning for the premises does not blow onto the cabinet.
The correct positioning of the cabinet optimises temperature conditions and
performance.
Cabinets with castors / wheels may be anchored to the wall behind them as
a safety precaution.
2.6. Cleaning before use
1. Clean the cabinet surfaces and the storage compartment for foodstuffs with a mild liquid
detergent (pH 6-8) before using the cabinet.
Follow the instructions provided with the detergent.
NOTE Make sure that all cleaning uids are classed as non-toxic.
2. Dry the surfaces carefully.

3. Electrical connections
NOTE The symbol marked on the cabinet (a lightning bolt inside a triangle) indicates
that there are components and wires under the cover containing live voltage.
Only personnel qualied to install and service electrical equipment are
permitted access to areas that contain live voltage.
Check the voltage and size of the fuse required from the rating plate xed to the cabinet. The
supply socket must be earthed. Fuse ratings for different types of plugs are presented in the
following table:
PLUG TYPE
16A Euro Schuko
13A BS 1363
16A CEE
32A CEE
2x16A Euro Schuko
2x13A BS 1363
3x16A CEE 3-Phase
No other appliances may be connected to the same fuse. The electrical connections for
the cabinet are shown in the wiring diagram in the plastic wallet attached to the side of the
electrical terminal box. Always replace the wiring diagram after use.
WARNING All electrical connections must be carried out by approved and qualied
personnel and comply with all IEE and local regulations. Failure to do so could
result in personal or fatal injury.
NOTE By default, the power cable of TectoPromo MD4 Visio is located on top of the
cabinet.
4. Operation
The cooling is achieved by a fan evaporator system. The evaporator is located at the bottom
of the cabinet’s tray. The cold air is blown to the shelves through the perforated back wall and
through the cooling cell in the top corner.
The cabinet is equipped with an electronic controller. In case the pressure rises to high, for
example because of dirt in the condenser, the controller stops the machine from running and
shows an error message (HA2).
On TectoPromo MD4 Visio, there is no separate switch for cabinet lights. The lights are
controlled by a button located on top left of the controller’s display panel. Please see the
picture on chapter Control device.
For more information on the control system, please see the corresponding chapters.

4.1. Starting up
NOTE Before connecting to the mains, make sure the condensate drain line runs to a
oor drain.
1. Connect the plug to the supply socket.
The compressor and fans start operating.
2. Wait for 90 minutes or until the desired temperature is reached.
The cabinet is now ready to be lled.
4.2. Loading cabinet
• Position the products carefully.
• Do not exceed the load limit. The maximum load on the shelves is 100 kg
per metre.
• Do not place products so that they protrude over the front edge of the
shelf or obstruct the inlet grid.
An unobstructed space of at least 20 mm must be left between the
shelves and the top plate of the cabinet. Products must not be placed
in front of the inlet and outlet grids and must not protrude over the front
edges of the shelves. Improper loading of the cabinet will disrupt the air
ow and raise the temperature of products in the cabinet.
See gures 2 and 3 on the inside cover.
• Do not place goods on top of the cabinet.
NOTE The cabinet is not designed to cool down products but to
maintain them at the temperature at which they are placed in the
cabinet. Food products warmer than the specied temperature
should not be placed in the cabinet.
4.3. Setting operating thermostat
The operating thermostat for the cabinet is located in the terminal box inside the machinery
compartments. The lid to the machinery compartment is xed with a spring. The thermostat is
preset to the correct temperature at the factory.
