10 Cleaning and Sanitization

Caution!
Ports on the back panel are not tight.
The Sterisart Universal pump is not suited for sanitization (gaseous or atomized)
with peracetic acid, hydrogen peroxide, or other decontamination procedures
commonly used in isolators, unless it is built into an isolator countertop.
These types of disinfectant can be used when the pump has been professionally
installed in the isolator.
Make sure that no liquids penetrate the socket of the external display and
control unit. If the external display and control unit is unplugged during the
cleaning process, the supplied protection cover must be inserted into the socket.
– Before cleaning the pump rotor, turn off the main power switch and unplug
the power cable.
The following parts of the pump have to be removed for cleaning:
– Bow, lever, support rod and draining container
– Disconnect the pump head:
– The rotor must be turned by hand until the marking on the upper side (black dot)
is pointing backwards.
– The marking indicates the position of the fastening screw that is located in
the rotor mid-section.
– Loosen this screw with a 4-mm Allen wrench. Do not turn the screw out
completely.
– Pull the rotor upwards.
– Pull the speed-selecting knob upwards.
