ADJUSTMENTS AND SETTINGS
Air Ionizer The air ionizer has no adjustments and the settings are factory set. Use the
following graphic and table to ensure that the switches on the control panel of
the air ionizer are set correctly:
Air Regulator The air regulator sets the air pressure to the air ionizer and must be set between
0.15MPa and 0.20MPa (1.5 bar and 2.0 bar). To adjust the air pressure, use
the following procedure:
1. Pull the regulator control valve upwards to unlock it.
2. Turning the regulator control valve clockwise to increase the pressure or
anti-clockwise to decrease the pressure, set the pressure between 0.15MPa
and 0.20MPa (1.5 bar and 2.0 bar).
3. With the pressure set, push the regulator control valve downwards to lock it.

REPLACEMENT PROCEDURE
Chapter Issue 2 Oct 06 Technical Reference Manual 25.5
REPLACEMENT PROCEDURE
Ion Level Alarm The air ionizer monitors the quantity of ions generated and if the level deterio-
rates, the ion level alarm indicator flashes on the air ionizer control panel. The
control panel is visible through the slot in the left hand safety cover.
Figure 25-1 Air Ionizer Control Panel
If the ion level alarm indicator flashes, one or more of the eight electrodes may
be dirty or faulty. It is recommended that the electrodes are cleaned and if the
ion level alarm indicator continues to flash, replace all the electrodes. A
replacement kit of 8 electrodes is available from DEK - Pt No 167123.
Use the following procedures to clean the electrodes and replace the electrodes
if necessary.

Electrode Cleaning 1. Ensure that the machine is isolated from mains electrical supply and the air
supply is disconnected.
2. Remove the left hand side safety cover from the machine to gain access to
the air ionizer.
3. Using a suitable cotton bud moistened with alcohol, clean the first electrode.
4. Repeat for the rest of the electrodes, moistening the cotton bud between
each electrode.
5. Refit the left hand side safety cover.
Electrode
Replacement
When replacing an electrode due to wear, all the electrodes must be changed
at the same time for the air ionizer to work efficiently. To change the electrodes,
use the following procedure:
1. Ensure that the machine is isolated from mains electrical supply and the air
supply is disconnected.
2. Remove the left hand side safety cover to gain access to the air ionizer.
