Maintenance and Servicing
8.4 Adjust door
A well-closing door is indispensable for temperature
and climatic test chambers. On Memmert
appliances, the tight closing of the door is
optimally guaranteed by a chamber seal and
door seal. In permanent operation, it is possible
that the flexible seal material will settle. To
ensure that the door closes exactly despite this,
an adjustment may be necessary:
1. Undo the grub screw with a Torx-TX8 tool
( Fig. 39 ). This is fixed with locking paint and
can be undone with a jolt.
2. Adjust door by turning the eccentric tappet
(2) with a screwdriver.
3. Tighten the grub screw again.
The locking plate ( Fig. 40 ) can also be adjusted:
1. Undo screws (1).
2. Move locking plate in direction of arrow.
3. Tighten the screws again.
8.5 Removing / cleaning the air
filter of the cooling unit
1. Open door
2. Remove and empty the drip tray ( Fig. 41 ).
3. Pull out the filter by the handle on the top
( Fig. 42 ).
4. Clean filter in a dishwasher or with a steam
cleaner.
5. Push the filter back in and reinsert the drip tray.
