Leave an unobstructed air gap of at least 20 cm behind 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.

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 16 A slow fuse for Norwell 190 and by a 10
A slow fuse for other Norwell models. 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 bottom of
the cabinet's tray.
The cabinet is equipped with an electronic controller, which turns off the cabinet's lights in case
of a pressure rise caused, for example, by dirt in the condenser.
See figure 1 on the inside cover for the location of the cabinet's light switch.

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 specified temperature should not be placed in the cabinet.
NOTE
4.3. Setting operating thermostat
The operating thermostat for the cabinet is located in the terminal box inside the machinery
compartment. The lid to the machinery compartment is fixed with a spring. The thermostat is
preset to the correct temperature at the factory.
