General
information
Memmert ovens require minimal servicing. It is recommended that the
moving parts on the doors (hinges and door lock) should be lubricated
with thin silicone grease once a year (with continuous use 4 times a
year).
In case of a malfunction which makes the opening of the unit
necessary this work has to be performed by a qualified service
engineer.
A tightly closing door is an essential requirement for proper operation of the oven.
MEMMERT ovens require perfectly tight closing of the door through a seal on the oven
casing. The door seal presses accurately against the casing seal. In continuous operation
the flexible seal material may acquire a permanent set. For proper closing of the door it
may be necessary to adjust the hinge or the locking plate.
15.1 Readjusting the door
After releasing the screw No.12
(NOTE! Screw No. 12 is secured with
adhesive. Loosen it by a sharp tug
with a hexagon socket key wrench 2
mm) the door can be adjusted by
turning the eccentric 13 in the direction
of the arrow (using a screwdriver).
Tighten screw No. 12 again.
In addition the upper part No.14 of the
door hinge can be moved slightly in the
direction of the arrow after releasing
the 2 screws at the top or bottom of the
door.
