The HDSL-028
Horizontal Ionizing Air Blower is a member of the United SCP
ElectraFlow ESD Ionizer family. The HDSL-028 blower is a wide area
unit designed to provide total coverage of an area of
approximately 24" x 48" and is used to control the
accumulation of static electricity on electrically
insulative surfaces and objects. The unit is
equipped with an on demand heater used to reduce
thermal shock syndrome prevalent with the
manufacturing of certain items.
Please read the complete
instruction manual before operating the device. This unit is
equipped with a 3-wire grounding plug and must be plugged into
a 3-terminal grounded socket. Do not modifying plug or using an
ungrounded power socket. If an extension cord is necessary, use
only a 3-wire extension cord that provides grounding.
Do
not insert objects through intake or outlet grille.
Do
not operate unit inflammable or explosive atmospheres.

INSTALLATION:
The Ionizing blower should be located
as close as possible to the work
surface for best results. There should be no cross flow of air between unit and
work surface. Drafts from air conditioning and heating air
outlets can affect performance of this unit.
2.1 Mounting
The HDSL-028 unit may be mounted using
the included adjustable mounting brackets.
The mounting brackets are designed for use on a variety of
surfaces.
2.2 Electrical
The HDSL-028 requires 220 VAC 50Hz/110VAC 60Hz.For proper operations.
The unit must be grounded for safe operation. The unit is
supplied with a standard heavy duty 3 prong (US
Style) plug. The color code for wiring the
plug is as follows: Red-line; Blue-Neutral; Green/Yellow-Ground.
Operation:
Activate the
HDSL-028
Horizontal Ionizing Air Blower by turning FAN SPEED knob
clockwise, out of the off position. The IONIZATION INDICATOR
will illuminate to indicate the presence of ionized air. Set
airflow as desired by adjusting FAN SPEED knob. If warm air is
desired turn on heater by setting heater
switch to the on (1) position.
The time required to
neutralize a static charge on an item in the air stream depends
on fan speed. Setting a higher fan speed reduces time required
to neutralize a static charge. When using the HDSL-028
unit in an electronics assembly area, the ionized air stream
should cover as much of the work area as possible. The constant
flow of ionized air will prevent items such as work surfaces,
tools, materials and components
from developing a static charge. Charged items introduced into a
work area will be neutralized and will remain neutral while in
the ionized air stream.
The HDSL-020 horizontal ionizer has been designed for minimal
maintenance. The only regular maintenance suggested consists of
emitter point cleaning, ion balance checking and ion output
checking. The HDSL-028 contains an advanced self balancing circuit
that compensates for
emitter point wear, line voltage fluctuations and variations in
air velocity.
Scheduled checking of ion
output and balance should be considered to assure quality audit
requirements however the units are extremely low maintenance and
reliable.
Maintenance:
4.1 Emitter Cleaning
To clean ion emitter
points: simply rotate point cleaner knob located at center of
each outlet clockwise to the stop (approximately one turn) and
release. The spring-loaded point cleaning brush will return to
its home position.
4.2 Air Inlet and
Outlet Cleaning
The air inlet grilles on
the top of the unit and ionized air outlets should remain clean
to prevent restriction of airflow. They can be cleaned with a
soft brush or vacuum.
4.3 Ion Output Check
Use a
charged plate monitor to test the unit for ion output. Discharge
times should be measured and checked against the following Ion
Output tables.

1. Distance measured in
mm, decay time measured in seconds.
2. Test data available
using ME 268A charge plate analyzer.
3.
Test figures are subject to the variation in the atmospheric
conditions
4.Discharge
times are in seconds from 1000 volts to 100 volts.
If a charged plate
monitor is not available, but a hand held electrostatic field
meter is available, ion output may be checked using the
following procedure.
1.
Take a
piece of plastic and rub it with cloth until a static charge can
be read with the static meter.
2.
Turn on the
HDSL-028 unit and set fan speed to high.
3.
Hold the
plastic one foot away from center ionized air outlet for five
seconds.
4.
Remove
plastic from ionized air stream and measure static charge. The
plastic should be neutralized.
If no instrumentation is
available, ion output may be verified with the following
procedure.
1.
Tear-off
about a 300mm length of Scotch brand (or equivalent) transparent
tape.
2.
Approach
non-adhesive side of tape with you free hand and note the
electrostatic attraction of tape to your hand.
3.
Pass tape
through the ionized air stream approximately 1 foot from unit
and again approach non-adhesive side of tape with your free
hand. If the tape has been neutralized, it will not attract.
CAUTION
ELECTRICAL SHOCK HAZARD
Do
not insert objects through intake or outlet grille.
Do
not try to verify operation of unit by drawing a spark from an
ion
emitter point. The design of the balancing circuit makes the
“park test”? Inconclusive. Sustained grounding of ion emitters
may damage balancing circuit.
4.4 Ion Balance Check
Use a charged plate
monitor to test unit for ion balance 0V +/- 10V.
Do not try to determine
ion balance by holding a static meter in the ionized air stream.
This
will result in a meaningless reading.
4.5 Calibration
Ion output of the
United SCP HDSL-020 unit is inherently balanced by design. As
a result, there are no calibration adjustments, If, after
checking ion balance as outlined in Section 4.4,an unbalance or
offset voltage exists in excess 0V +/- 10V, contact United SCP Customer Service
in the USA at 719 676 3928.
