General advice

In the unlikely event that you experience any problems with your 
refrigerated unit which cannot be easily remedied, you should 
contact your supplier and return the unit if necessary. Please 
include any details of the fault observed and remember to return 
the unit in its original packing. Techne accept no responsibility for 
damage to units which are not properly packed for shipping: if in 
doubt, contact your supplier.

If the power light on the power switch is lit, the fuse may have 
blown. Make sure there is no external cause (such as a faulty plug 
or lead).

may need to return the unit to your supplier for repair.
