APPLIANCE ROUTINE MAINTENANCE / CLEANING

CONDENSER CLEANING

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. 

TOP MOUNTED CABINETS 

(WMP620 - WMP1295) 

The condensing unit and refrigeration equipment 

can be accessed from above or in some cases 

behind. Remove fixings in the top and bottom edges 

of the unit cover and pull the unit cover away from 

the cabinet and retaining clips.

BOTTOM MOUNTED UNITS

(WMP523)

 

Pull the unit cover away from the cabinet 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. Please ensure that all 

redundant parts are disposed of safely and legally.
