We recommend that the pump head be autoclaved before the rst use and after each workday.
See the Maintenance section.
Whenever the pump head is removed, the Tare cycle must be run (see below).
It is also recommended to sanitize the pump interior before the rst use and after each workday, and
if the pump is unused for more than a day. See Sanitizing below, in this section.
