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.

ION OUTPUT (DISCHARGE TIME):

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.
