APPLIANCE ROUTINE MAINTENANCE / CLEANING

SHELF / SUPPORT / RACKING REMOVAL

First remove the shelves, then remove the shelf 

supports by grasping firmly in the centre and lifting 

slightly. Turn the shelf support towards the interior 

of the cabinet by pushing it in the centre as you 

twist the support through 90°. The shelf support 

will be released. (NB: the supports are designed 

to be anti-tilt and you may therefore experience 

some resistance at first which will be overcome with 

practice). When all shelves have been removed, 

remove the racking by lifting up and over the nylon 

retaining blocks.

CONDENSER CLEANING

(Only applicable to Air Cooled Units)

 

Regular maintenance should be carried out on a 

regular basis by competent / trained personnel.  The 

condenser is part of the refrigeration unit and is 

located in the unit compartment. 
Brush fins vertically with a stiff brush, taking care 

not to damage them or to push dirt / dust further in, 

and then vacuum away. 

To cancel the flashing LED, press and hold 

 for 3 

seconds.
If there are further grease deposits still remaining 

on the condenser call your Service Provider to carry 

out a full service.

Note:  Non-compliance may invalidate your 

Warranty.

REMOVING THE UNIT COVER

Remove the screws in the top and bottom edge of 

the unit cover and pull the unit cover away from the 

unit and retaining clips.

CLEANING / REPLACING THE GASKET

Door gaskets should be checked and cleaned 

regularly and replaced if damaged. To clean the 

gasket, wipe with warm soapy water and a soft cloth, 

ensuring it is completely dry before closing the door. 

DO NOT

 use a sharp knife to clean or scrape the 

gasket. Damaged gaskets do not seal correctly and 

can increase the amount of electricity consumed, 

seriously affecting the efficiency and performance of 

the appliance.

Damaged gaskets are easily 

replaced. Simply pull out the 

existing part and push the new 

gasket into the channel (gasket 

retainer) at the centre and 

work along, pushing gasket into 

channel.

EVAPORATOR/DRAINLINE

Inspect periodically to ensure the drain hole is not 

blocked.

BREAKDOWN

In the event of a breakdown, please contact Williams 

Refrigeration or your Service Provider
When calling, please advise model and serial 

number. This information can be found on the data 

plate inside the appliance. It should also be noted 

on the cover of this Manual. Please ensure that all 

redundant parts are disposed of safely and legally.
