Service Manual Information  

 

The products and all information in this manual are subject to change without prior notice. 

We assume by the information given that the person(s) working on these refrigeration units are fully trained and 
skilled in all aspects of their workings. Also that they will use the appropriate safety equipment and take or meet 

precautions where required. 

The service manual does not cover information on every variation of this unit; neither does it cover the installation 

or every possible operating or maintenance instruction for the units. 

 

 

Health & Safety Warnings and Information  

 

 

Make sure the power supply is turned off before making any electrical repairs. 

 

To minimise shock and fire hazards, please do not plug or unplug the unit with wet 

hands. 

 

During maintenance and cleaning, please unplug the unit where required. 

 

 

Care must be taken when handling or working on the unit as sharp edges may cause 

personal injury, we recommend the wearing of suitable PPE.

 

 

Ensure the correct moving and lifting procedures are used when relocating a unit.

 

 

Do NOT use abrasive cleaning products, only those that are recommended. Never 

scour any parts of the refrigerator. Scouring pads or chemicals may cause damage by 

scratching or dulling polished surface finishes. 

 

Failure to keep the condenser clean may cause premature failure of the 

motor/compressor which will NOT be covered under warranty policy. 

 

Do NOT touch the cold surfaces in the freezer compartment. Particularly when hands 

are damp or wet, skin may adhere to these extremely cold surfaces and cause frostbite. 

 

 

Please ensure the appropriate use of safety aids or Personnel Protective Equipment 

(PPE) are used for you own safety.
