MAINTENANCE
General MEMMERT appliances require very little maintenance . It is
information recorrmended that the moving parts on the doors (hinges and
door lock) should be lubricated with a thin silicone grease
once a year (with continuous use 4 times a year).
A well-fitting door is an essential requirement for ovens. Oi Memmert
ovens the tight fit of the door is ensured trough seals both on the
cabinet and on the door. The door seal presses exactly on the cabinet
seal. With continuous use the flexible sealing material may becarie "set

.
It may be necessary to adjust the door at the hinges and/or the locking
plate area to ensure that the door closes properly.
Adjusting After releasing the screw 16 the door can be adjusted by
the door turning the eccentric 17 in the direction of the arrow
(using a screwdriver). In addition the upper part 18 of the
door hinge can be slightly moved in the direction of the
arrow after releasing the 2 screws at the top and bottom of
of the door.
The locking plate can also
be adjusted in the direction
of the arrow after releasing
the screw 19.
