Starting the
maintenance
routine of the
Alyza IQ
For all activities at the open measuring unit:
 Note the environmental conditions (see section 3.3.1 Require-
ments of the measurement location,
 26).
 With low ambient temperatures, make sure that the liquids do not
freeze while the maintenance activities are carried out. Leave the
housing open for as short a time as possible.
 Open the outer housing door far enough so the arrestable brake-
stay catches.
 Open the inner housing door far enough so that it touches the
outer door. Tilt the angular sheet (at the inside of the outer door)
over the upper edge of the inside door.
