Maintenance
DISCONNECT THE POWER SUPPLY BEFORE MAINTENANCE FOR THE MACHINE!
1. Keep the door gasket clean, remove it from the door and wash it. Dry and seal it as before. Putting some
talcum powder on the magnetic surface would prolong its service life.
2. Bulb replacement: remove the lamp shade, take out the bulb, replace with a new bulb, then mount it again.
3.
If there is heavy frost on the evaporator after long usage, take out the stuff inside the case, disconnect the
power, the frost will melt automatically, clean up the water and connect the power again.
4.
Use a soft cloth and dip some water or soap (Non-caustic, neutral detergent is also available) to clean the
unit. Dry the unit after cleaning to avoid rust.
5. Do not use organic liquid, boiled water, washing powder or acid stuff to clean the unit. Rinsing the case by
water is not allowed, don’t use hard brush, steel brush to clean the case.
6. If the unit will not be used for a long time, disconnect the power, clean it by following the above steps, wipe
off the water inside the case with a soft cloth.
