9 Loading
Ovens described in this instruction manual must not be used for
drying or warming substances which generate ignitable vapours
when mixed with air.
The ovens described here must never be operated in areas with an
explosive atmosphere.
For correct operation and uniform temperature distribution it is essential to maintain free
air circulation throughout the oven. The contents of the oven should therefore not be
packed tightly, furthermore they must not be placed close to any of the heating ribs on the
sides, top or bottom of the oven (note the loading diagrams on the ovens).
In order to ensure optimum air circulation the shelves should be arranged to have roughly
equal gaps between door, shelf and the rear of the working chamber.
For the maximum number of shelves with the permissible load, see table below.
In certain situations where, for example, the load is packed tightly and the ventilation slide
is fully open it is possible that the unit will control at a temperature below that set on the
thermostat. In order to compensate it may be necessary to increase the thermostat setting
until the desired temperature is shown on the digital display of the working controller.
The following schedule gives recommended loading levels which will ensure
homogeneous temperature distribution within the working chamber.

10 Maintenance
General information
Memmert appliances require minimal servicing. It is recommended, however, to lubricate
the mechanical parts of the doorhinges and movable parts of the door lock from time to
time. Under normal conditions this should be done annually but up to four times a year if
undergoing continuous operation. Use a heat resistant oil or thin silicon grease. The
movable parts of the temperature controller should be lubricated too. Therefore use silicon
grease.
In case of a fault which makes necessary to open the oven it has to be checked by
a qualified service engineer.
Adjustment
It is necessary to keep the top of the oven closed in case of readjustment.
Empty oven with one empty shelve in the middle has to be heated up to maximum
temperature and allowed sufficient time to reach steady temperature condition. (Please
wait at least 60 min.).
