Maintenance and Servicing
8.3 Adjusting door
A well-closing door is indispensable for climate chambers. On Memmert appliances, the tight
closing of the door is optimally guaranteed by a chamber seal and a door seal. In permanent
operation, it is possible that the flexible seal material will begin to sag. To ensure that the door
closes exactly, however, an adjustment may be necessary:
1. Undo mounting bolts ( Fig. 36 , 2) at the top and bottom of door.
2. The top section of the door hinge (1) can now be moved slightly in the direction of the
arrow.
3. After undoing the Allen set screw (5), the door can be adjusted by turning the eccentric (3)
with a screwdriver.
The Allen set screw (5) is fixed with lock washer varnish. It can be undone with a jolting
motion using a 2 mm Allen key.
4. Apply lock washer varnish to the Allen set screw (5) and screw tight the set screw.
5. Tighten the mounting bolts (2) again.
The locking plate (7) can also be adjusted in the direction of the arrows after undoing the
screws (6) ( Fig. 37 ). Afterwards, screw the locking plate back firmly.
