Leave an unobstructed air gap of at least 20 cm above the
cabinet.
When installing the cabinet, make sure of the following:
• The area where the cabinet is placed is flat 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, air blown heater or spotlight.
See figure A.
• The cabinet is not exposed to direct sunlight. If necessary,
use blinds in any nearby window. See figure B.
• The air conditioning for the premises does not blow onto
the cabinet. See figure C.
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.

3. Electrical connections
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 qualified to install and service electrical equipment are permitted access
to areas that contain live voltage.
NOTE
Check the voltage and size of the fuse required on the rating plate attached to the cabinet. The
supply socket must be earthed and protected by a 10 A slow fuse. No other appliances may be
connected to the same fuse.
All electrical connections must be carried out by approved and qualified personnel
and comply with all IEE and local regulations, failure to do this could result in
personal or fatal injury.
NOTE
4. Operation
The cooling is achieved by a fan evaporator system. The evaporator is located at the top of the
cabinet. The cold air is blown to the shelves via the air passage located in the back wall.
The cabinet is equipped with a Dixell XR40CX or NRC-100 controller.
In case the pressure rises to high, for example because of dirt in the condenser, the Dixell XR40CX
controller stops the machine from running and shows an error message (HA2).
NRC-100 controller turns off the cabinet's lights in case the pressure rises. See figure
1 on the inside cover for the location of the cabinet's light switch.
For more information on the different control systems, please see the corresponding
chapters.

An unobstructed space of at least 50 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 flow and raise the temperature of products in the cabinet.
See figures 2 and 3 on the inside cover.

4.3.1. Eco switch
Save energy by using the Eco switch. Turning on the Eco switch allows the cabinet temperature
to rise from the normal temperature of +4-6 °C up to +8-10 °C and saves energy approximately
12% compared to the consumption in the normal state.
