Mission Critical Overhead ESD Ionizer with Lighting
Specifications and Installation
Method of operation and uses: The HDO-205 is an extreme service mission critical overhead ionizer. The HDO-205 emits a powerful yet balanced ionic output that overwhelms static laden insulative items or conductive items that are insulated from a ground source.
Typical Decay Test Results
Installation: Install energy efficient light bulbs (included with the ionizer) into the unit by removing the front cover with a screw driver, unpacking bulbs, screwing them into place and replacing the front panel. The HDO-205 is an overhead unit designed to provide ideal coverage for control of electrostatics. Note: Do not insert objects into air intake or outlet grille and do not operate the HDO-205 in inflammable or explosive environments. The HDO-205 ionizer should be affixed approximately 24 to 36 inches above the work surface with fans targeted directly over the work area. Avoid drafty locations such as that caused by air conditioning, heater outlets, etc.
Attachment to overhead supports: S hooks and chains may be used for mounting these ionizers to structurally sound ceilings or wire shelves. Chains and mounting hardware should have a minimum safe working load of at least 50 pounds. When mounting the unit to ceilings it is important to check state and local codes to insure compliance. These units are typically hung in the same fashion as an overhead light fixtures (independently attached to the overhead building superstructure). Attachment to suspended ceilings only are typically not compliant with local codes. Mounting to workbench overhead supports: These ionizers may be mounted to work bench overhead shelves and beams using the supplied side mounting bracket in conjunction with angle iron, bolt on L brackets etc. These ionizers may be used either horizontally or vertically.
Electrical Requirements: The HDO-205 requires 110VAC /60Hz power. These units must be grounded. Each unit is supplied with a standard US 3 prong male grounded power plug. Do not modify the plug or use an ungrounded 3 prong receptacle. If an extension cord is required use heavy gauge fully grounded cords only.
Operating Procedure: Activate the HDO-205 overhead ionizing blower by turning fan speed knob clockwise. The ionization indicator will illuminate and indicate the presence of ionized air. Airflow speed can easily be adjusted utilizing the fan speed knob. Light is provided via a simple on/off switch. The time required to neutralize electrostatic potential is dependent on distance of ionizer to work surface and speed of fans. When used in electronic assembly the ionized air stream should cover as much of the working area as possible. The constant flow of ionized air prevents items from developing an electrostatic potential and neutralizes electrostatic charges present on objects introduced to the airflow.
Routine Maintenance: Inspect the emitter points on occasion. They should look clean and sharp. To clean the emitter pins press and turn the point cleaner knob (located in the middle of each air outlet) clockwise approximately one turn and reverse the assembly to lock it into the start position. Clean air inlet and outlets as needed with a soft brush or vacuum. Periodically test ionic output as indicated by your internal ESD program or ANSI/ESD S 20.20-2014, TR53, Air Ionizer Compliance Verification (discharge time and offset voltage). Offset voltages of >+/- 35 volts or decay times that exceed user defined specifications (typically < 3.0 sec @ 40%rH and 68 deg F. with ionizer positioned 24" from the center of the work surface) may indicate the need for replacement of emitters. Normal emitter life is 5 to 10 years, replacement emitters are easy to install and available from United SCP.
