6. Adjust the SPEED knob slowly until the
required stirring speed is achieved. Allow
sufficient time for the mixing operation to
attain uniform rotational flow. The stirring is
indicated in the rpm LCD (D) for models HI
303N and HI 313N.
7. After stirring is completed, turn the SPEED
knob to off. If no further stirring is required
switch off the stirrer and disconnect the
power supply.

Models: HI 302N, HI 304N normal stirrers and
HI 312N, HI 314N Auto-Speed stirrers
These reversible stirrers allow you to stir the
fluid in both directions and are ideal for powder
mixing applications to ensure a homogeneous
final product and complete dissolution of hard-
to-wet powders. The reverse stirring period is
adjustable from 30 sec. to 30 min. When set at
say 1 min., the fluid will rotate in one direction
for min. and then reverse its rotation for another
min. at the desired speed in a repeated cycle
until the stirrer is switched off.

Model: HI 322N, HI 324N Auto-Speed Stirrers
These Auto-Speed stirrers are equipped with
timer control to start and automatically stop the
stirring process after a duration which can be
preset from 5 min. to 2 hours and are ideal for
routine stirring applications where the required
stirring is known. They therefore free the
operator from constantly having to monitor the
stirring process.
