Always disconnect the power if interruptions in power supply occur, and when electrical 
parts are removed/put on, and before cleaning and maintenance of the product. 
 
Repairing of electrical/technical parts may only be performed by a service electrician from 
Gram Commercial or an authorised refrigeration company with knowledge of Gram’s 
products. 
 
Do not re-connect the product to the main supply or use the product before all coverings 
are installed, so that live or rotating machine parts can not be touched. 
 
The product is not to be used outdoor.  
 
All earthing requirements stipulated by the local electricity authorities must be observed. 
The plug and wall socket should then give correct earthing. If necessary, contact an 
electrician. 
 

 

Make sure the product is disconnected at the wall socket or at the 
cabinet inlet as shown above (Fig. 5), before service is performed on 
electrical parts. It is not sufficient to switch off the product by the 
START/STOP key as there will still be voltage to some electrical parts of 
the product. 

 
 

General use   

 

 

 

 

Do not damage the refrigeration system parts. 

 

During normal operation, some parts of the refrigeration system in the 
compressor compartment might reach high temperatures, and could therefore 
cause burns if touching these components.

 

Do not use electrical devices inside the product. 

 

To ensure correct and efficient air flow in the cabinet, the upper and lower areas 
must be kept free of items as shown on the next page. (see Fig. 6) 

 

All items to be stored, that are not wrapped or packed, must be covered in order 
to avoid unnecessary corrosion of the inner parts of the cabinet. 

 

If any controller parameters are changed from default, this could cause that the 
product is not functioning normally, and harmful temperatures could damage 
items that are kept inside the product.

 

If the product is turned off, wait minimum 3 minutes before turning it on again. 
This is to protect the compressor from damage
