C. Airflow Adjustment
The motor is equipped with a variable pitch pulley to
allow for minor adjustments in cubic feet per minute
(cfM) of airflow.
increasing blower speed (rPM) will increase airflow
(cfM) and current (amps). to increase speed, close the
variable pitch pulley from “normal Setting” (fig. 11a)
toward “fully closed” (fig. 11B). Decreasing blower
speed will decrease airflow and current. to decrease
speed, open the variable pitch pulley from “normal
Setting” (fig. 11a) toward “fully open” fig. 11c).
to adjust the variable pitch pulley:
1. Loosen motor base nuts, adjust motor slide base and
remove the drive belt.
2. Loosen set screw “a” to clear the drive key between
pulley halves.
3. remove the key.
4. adjust pulley in increments of one turn to the desired
setting.
5. install key and tighten set screw “a.”
6. install drive belt.
7. Loosen set screw “B.”
8. align belt centerlines of motor and blower pulleys
using straight edge and square.
9. Set belt tension using a belt tension gage.
11. TROUBLESHOOTING
Tools Required:
• Screwdriver 8” (200mm) or longer with plastic handle
• Volt-Ohm-Meter — used to check low voltage input
(115 Vac) and continuity (oHMS)
• High Voltage Probe (optional) — used to check high
voltage power supply. range: from 0 to 15 KVDc
risk of electrical shock. the high voltage circuits to
the ionizer and collector should be grounded before
removing/installing high voltage wires and/or removing
the ionizer(s)/collector cell(s). Grounding can be
accomplished by waiting one minute after placing power
in the off position or refer to figures 4 and 5. the power
pack total current output is limited to a maximum of 5
milliamps to ensure personnel safety.
Troubleshooting Procedures
High voltage issues can generally be isolated by referring
to the indicator light.
• When the light illuminates, high voltage is present from
the power pack to the ionizer and collector cell circuits.
• A flashing indicator light indicates a failure in the high
voltage circuits.
there are four conditions which may cause a flashing
indicator light.
a) the high voltages are below specifications to the ionizer
and/or the collector cell circuit(s).
b) there is an arcing condition to the ionizer and or
collector cell circuit(s).
c) there is a dead short condition.
d) the power pack has failed.

WARNING
The SHN Series is equipped with an external limit
switch (120 Vac to the power packs) engaging and
disengaging by the component access door. the limit
switch should be engaged manually after placing
the power in the on position to the SHn unit, and
disengaged when placing power in the off position
during the troubleshooting steps. the engagement and
disengagement of the limit switch is not identified in the
troubleshooting steps.
!
WARNING
Power pack enclosures service voltage can range
from 120Vac to 460Vac. When servicing the power
pack enclosure, place power in the off position by the
disconnect switch supplied by others.
