INSTALLATION

REMOVAL OF REDUNDANT APPLIANCES

If the product needs to be disposed of, the relevant 

legal regulations must be observed.
Within the European Community, the disposal of 

electrical devices is regulated by national regulations 

based on EU Directives pertaining to waste electrical 

and electronic equipment (WEEE).
According to these regulations, any devices supplied 

after August 13, 2005, in the business-to-business 

sphere, to which this product is assigned, many no 

longer be displosed of in municipal or domestic 

waste.  To document this, they have been marked 

with the following marking:

Do not dispose of batteries together with domestic 

waste.  Dispose of batteries in accordance with local, 

legal regulations.
Refrigeration appliances contain refrigerant and 

gases in their insulation and must be disposed of 

professionally by a licensed waste management 

contractor. 
Please ensure that old or redundant refrigeration 

appliances are disposed of safely and legally. It is 

recommended that doors are removed prior to 

disposal in order to ensure safety.

Because disposal regulations may differ from one 

country to another within the EU, please contact 

your supplier if necessary.

UNPACKING

Remove all external and interior packing and 

accessories. Ensure all such material is disposed  

of safely.
Check that no damage has occurred to the 

appliance, the tubing of the refrigeration system 

power cable and plug top during transit. If damage 

has occurred do not use the appliance.
The appliance should be installed in a well ventilated 

room on a flat and level floor.

PROTECTIVE COATING

The polished stainless steel surfaces are protected 

during manufacturing and transport by an adhesive 

plastic coating. 

This should be removed prior to placing your 

appliance into use. Carefully peel away to reveal 

the polished stainless steel surface. Care should be 

taken to ensure that no adhesive residue remains 

on the surface. Any stubborn or tough adhesive 

marks can be removed by following the advice on 

Page 10.

INSTALLATION

During the initial start up, high temperature alarm 

may sound while the appliance reaaches operating 

temperatures.  Allow the appliance to stabilise at the 

set point before storing product. 

 

VENTILATION

 

Refrigerators generate a considerable amount of 

heat and, if operated in a small unventilated room 

will quickly cause the room temperature to become 

excessive. This could cause the motor to overheat 

and possibly damage the compressor. At the very 

least, such an installation will cause the unit to use 

an excessive amount of electricity. 
In addition to ventilation in a room, please ensure 

that cabinets with top-mounted systems have 

500mm clearance between the cabinet top and the 

ceiling for engineer access and ventilation. For all 

other cabinets, please ensure a minimum clearance 

of 50mm is provided around the unit to ensure 

efficient and effective performance.

 

 

LEVELLING (CASTORS/FEET)

The appliance should stand level to ensure the 

correct operation of self-closing doors and proper 

drainage of condensate from the evaporator.

Models fitted with castors are non-adjustable. 

Therefore a level platform / floor should be 

provided where the appliance is to be located. 

Where swivel and brake castors are fitted and it 

has been positioned, please ensure its brakes have 

been activated by pressing the metal bar down. 

Remember to release the brakes before trying to 

move it.

On models fitted with levelling feet, levelling may be 

achieved by adjusting them first.

If the appliance has been laid on its back 

or tipped, DO NOT switch on immediately. 

Leave in an upright position for at least 3 

hours before switching on.

Do not block vents by stacking boxes on top 

or in front of the unit as this could affect 

performance and give rise to safety risk.
