Maintenance and care
Important Notification: before cleaning the electric oven, make sure to cut off power of the electric oven first
and never clean with steam.
Always keep the electric oven clean and make sure that no grease and oil is accumulated around the
heating elements and fan; the ovenware and w , etc. should be cleaned up, in order to prevent a fire from
being caused by accumulated grease; before baking of meats, warp the meats with a piece of aluminum foil in
order to make it convenient for later cleaning; all the greases and oils will form a layer of lacquer deposit which is
difficult to be cleaned in the electric oven. Therefore, the electric oven shall be cleaned thoroughly after every
use.
1. Cavity of electric oven: clean it with warm water without using any corrosive or abrasive detergent; the
stains which are difficult to be removed can be cleaned with a nylon brush or mild detergent rather than a steel
wire ball, in order to avoid the surface from being left with un-repairable damages. The detergent to be used in
the cavity should be cleaned up and no residue shall be left. After cleaning, wipe cavity out with a piece of wet
cloth and keep it dry.

dirty. The dirt that is difficult to be removed shall be cleaned with mild detergent rather than a steel wire ball, in
order to avoid the surface from being scratched. After cleaning, dry it with a piece of cloth.
3. Removal and installation of fan cover plate: the fan cover plate is fixed to the internal cavity with 4 bolts
and can be removed by screwing these bolts anticlockwise. Note: the fan cover plate should be reinstalled after
being cleaned.
4. Removal and installation of lighting lamp in electric oven: remove the lighting lamp of the electric oven
by rotating the glass lamp cover anticlockwise and then pull out the bulb; inset the bulb upward and rotate the
glass lamp cover clockwise so that the lighting lamp of the electric oven is reinstalled.
5. In order to make it convenient for cleaning the top of the cavity, you can flip the upper heating tube down.
First, rotate the fixation column of heating tube for 90 degrees (as shown in Fig.1), at this moment, the fixed plate
at front end of heating tube will separate from the fixation column and then the heating tube can be flipped down
about 20 degrees (as shown in Fig.2). Then retighten the upper heating tube in opposite direction, and reinstall
the fixed plate of upper heating tube to the fixation column, then rotate it for 90 degrees.
