CAUTION!
• When changing the chemical medium, check whether the pump and the system’s
materials of construction are chemically resistant. If there is danger of a chemical
reaction between different media, a thorough cleaning is first mandatory.

the adjusting knob may change its position. Thus causing irregular flow rates.
CAUTION!

base of the pump, the pump must be elevated.
DANGER!
• Fire hazard. Pressure surge: catapulting parts could kill you. MIDIDOS E must not be
used under any circumstances in an explosive environment.
