3. Installation

DANGER

Only qualified personnel, following the local security regulations, should conduct the tasks described in this section of the

manual.

3.1. Assemblage

1. Unpack the instrument.

Note: Stirrer replacement

Before replacing the stirrer, disconnet it from the rear panel and

release the cable from the bottom of the instrument.

2. Verify that the shift is in

the same position than

in the picture.

3. Drive the stick into the

hole.

4. Turn the shift in a

counterclockwise until

the stick is well fixed.

Place the o-ring at

135-140 mm from the

base in order to avoid

the shock of the sensor

against the bottom of

the glass.

5. Place the electrode’s

support on the stick by

softly pressing the

button.

Holder for 3 sensors.

PN= LZW9321.99

6. Place the electrode on

the electrode’s support.

Insert the electrode’s

cable through the

groove.

1. Turn the stirrer to

release or fix from base.

2. Pull up the stirrer and

replace it.

Place the cable of the

new stirrer through the

bottom groove of the

instrument.
