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 or painted aluminium & may be cleaned with a
gentle cleaner. The door is also plastic lined/stainless steel or glass 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 manufactures 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.
The condensor fan motor should be cleaned every months by switching off the power and vacuuming the dust and wiping
the grime build up away. Where possible leave the unit off with the door open every 6 months for 6 hours to allow any
frost to melt away.
Defrosting
Over a period of time the chamber cooling coil will build up a layer of frost which will reduce the operation of the
fridge/freezer. We recommend defrosting when the ice frost layer is around 5mm thick or when the fridge/freezer 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 or if a temperature of 12°c for a period of 10 minutes is acceptable then set auto defrost for a period once every 24
hours for 10 minutes. The temperature may increase to as much as 12°c but it will reduce the need for manual defrosting
of the chamber as often. Product temperature should not change during the short period of the cooling compressor being
switched off – no heating is used during auto defrost.
