Maintenance
The cabinet is finished with painted epoxy and to maintain appearance, should be wiped over
with a non abrasive household cleanser. The chamber is manufactured from formed plastic and
may be cleaned with a gentle cleaner. The door is also plastic lined and should only be cleaned
with general purpose cleaners.
If a fan motor is fitted the fan motor is pre­lubricated with sealed bearings which should not
require maintenance for some time depending upon extent of usage. The shelves are
manufactured from plastic coated steel and a non abrasive cleaner should be used. The
magnetic door gasket should be cleaned with detergent only, ensuring it is dried completely
after washing.
Defrosting
Over a period of time the refrigerator’s cooling coil will build up a layer of frost which will reduce
the operation of the unit. We recommend defrosting when the ice frost layer is around 5mm
thick or when the refrigerator starts to slowly heat up in temperature. Turn the unit off for a
period of 24 hours with the door opened to allow the frost to melt away. This should be done
every 3 months or as required.
