The bath is lowered automatically when the unit is switched
off or in case of a power failure to ensure that the evapora-
ting flask will in all cases remain outside the source of heat
(optional).
Rotation
The rotation is provided with a „soft start“ function. The flask
rotates at a very low speed for approx. 5 seconds and then
increases its speed to the set value. The „Rotation ON“ button
must remain depressed during this time.
The speed can be set to a value between 0 and 100 revo-
lutions (
).
Bath lift
The bath lift is provided with an upper and a lower stop and
thus cannot travel too far up or down.
