Filling
In order to garant the high quality of the stainless steel it is recommended by the
steel producer to fill the waterbath with deionised water.
Draining The tank can be drained through the drain valve. The thermostating fluid must be cooled
to room temperature before draining. Drain the fluid either directly into an appropriate
container or connect an appropriate hose to the drain valve.
Operation with non-flammable thermostating liquids only!

IMPORTANT! The bath has to be filled up to a level between the
two markings at the right side of the tub!
Waterbaths can be fitted with a
level control system (see section 9).
NOTE: Polluted fluids may not be drained directly into the public
wastewater system! If the thermostating fluid is polluted, please
make sure that it will be properly filtered or dumped according to
the applicable regulations!
