MEASURING UNICELL IONIZER VOLTAGE
1. Turn the unit off, open the faceplate grille (this will
disengage the safety interlock).
2. Connect the ground clip of the positive polarity
probe to the cabinet.
CAUTION: Always ground the high voltage probe
to a solid ground connection on the
metal cabinet.
3. Turn unit control to the “on” position and
cautiously engage the safety interlock switch. It is
located in the slot as shown in the top photo.
CAUTION: Be sure to disengage safety interlock
switch after measuring voltages.
4. Place the probe’s tip on the ionizer contact stud and
measure the positive DC voltage. The voltage
should read 10.0 to 11.0 KV DC.
If measurements are abnormal, refer to the trouble-
shooting guide for cause and correction.
MEASURING UNICELL COLLECTOR VOLTAGE
1 . Connect the ground clip of the positive polarity
probe to the side of the cabinet.
2. Engage the safety interlock switch and measure the
collector high voltage by placing the probe’s tip on
the cell contact stud. The voltage reading should be
4.0 to 6.0 KV DC.
If measurements are abnormal, refer to the trouble-
shooting guide for cause and correction.
CHECKING THE POWER PACK OUTPUT
1. Remove the prefilter and unicell from the cabinet.
2. Check the high voltage lead wires to make sure
there are no cuts, frayed wire or breaks in the
insulation.
3. Engage the safety interlock switch and measure the
ionizer output voltage by placing the probe’s tip on
the #8 high voltage plug-in connector.
Output reading without the unicell should read 11.0 to
12.0 KV DC positive.
4. To measure the collecting cell output voltage, place
the probe’s tip on the #7 high voltage plug-in con-
nector.
Output without the unicell should read 5.5 to
6.1 KV DC positive.
