SECTION 1: Description

Simco-Ion’s Guardian CR2000 is an overhead ionizing air blower designed specifically
for use with sensitive electronic components in cleanroom applications where
electrostatic discharge (ESD) is a concern. The Guardian CR2000 Ionizing Air Blower
produces an airflow that is rich in positive and negative air ions. Directing the airflow
onto an object that has a static electricity charge will quickly neutralize the charge. If the
object has a negative static charge, it will attract positive ions from the airflow.
Conversely, if the object has a positive static charge, it will attract negative ions from the
airflow. The volume of airflow is controlled by variable speed control of the fans, which
provides a wide range of airflow settings. The airflow can also be locked into high speed
using the key switch to provide assurance of the maximum possible performance.
Airflow is directed through ionizing elements which produce air ions. These ionizing
elements are shrouded by ducts to eliminate airflow within the unit's chassi s . Th e
ionizing elements are energized with a low current, hi g h voltage signal. The system
contains current limiting resistors which enhances ionization stability and provides for
safety. The signal is applied to a circular arrangement of ion emitters which results in an
alternating polarity ion field. The airflow exiting the Guardian CR2000 carries these ions
to the work area to provide static neutralization.

New design features enhance both short-term and long-term ion balance stability. A
transparent duct extends from each fan output. These "i on shi el ds" pr event ion loss to
the unit's chassis and preserve ion output and balance. The Guardian CR 20 00 f eat ur es
a balancing circ uit . Th e outpu t fro m the mo ni tor i ng circuit is indicated with two bicolor
LEDs on the face of the unit. The Guardian CR2000 also offers bui l t -in emitter point
cleaners as a standard feature to make it easy to maintain optimum performance. To
ensure cleanroom compatibility, the Guardian CR2000 uses specially chosen
components which minimize the risk of particulation. All fans feature a specially
designed bearing system and use silicone-free lubricants. Fans are particle tested to
Class 10 cleanroom particle limits. Airflow surfaces are free of silicone materials to
further minimize the risk of contamination.

SECTION 2: Safety

• Read instruction manual before installing or operating device.

• This unit is equipped with a 3-prong grounding plug and must be plugged into a
3-terminal grounded receptacle. Do not defeat electrical ground by modifying

SECTION 5: Installation

Location

The Guardian CR2000 should be located 20 to 30 inches above the work surface,
centered directly above the critical area. Other than the vertical unidirectional airflow,
there should be no cross-flow of air between unit and work surface.

Mounting

The Guardian CR2000 may be moun t ed usi n g adjust able mounting brackets or "S"
hooks provided. The mounting brackets are designed to secure to a variety of surfaces
such as: perforated steel angle, Unistrut® metal framing and provide permanent
mounting on Metro® wire shelving. First, install hanger brackets to to p of Guardian
CR2000 chassis using a Philips head screwdriver. Then, mount brackets as shown in
illustration. When using lock knobs, place a lock washer and flat washer on the lock
knobs and secure unit using center hol es on mounting tabs.

The "S" hooks provide for chain mounting or mounting on wire shelving. Install the
Guardian CR2000 as shown in illustration using outer holes on hanger brackets. Chain
and mounting hardware (not supplied) must have a minimum safe working load rating of
20 lbs. (10 kg.). Close "S" hooks to secure unit.

Electrical
The Guardian CR2000 is equipped with an IEC320 power inlet and outlet. An

appropriate line cord is included in the packaging. The unit must be grounded for safe
operation. Plug unit into a standard 3-terminal grounded receptacle with line voltage and
frequency as listed on serial label of unit. If an extension cord is necessary, use only a
properly rated 3-wire extension cord that provides grounding.

NOTE: The 100 and 120VAC Guardian CR2000 models are equipped with an internal
self-resetting fuse to protect the high-voltage transformer in case the wrong line voltage
(230 VAC) is applied. If a 100 or 120 VAC Guardian CR2000 is connected to 230 VAC,
the fans will continue to run, but both Output and Balance indicator lights will turn red. If
this occurs, turn off the unit and wai t for one minute to allow the fuse to reset, and then
connect the CR2000 to the proper line voltage.

Optional Daisy Chaining

If desired, power to units may be daisy chained using the IEC320 power outlet and
optional daisy chain power cord. Up to 10 units may be daisy chained.

SECTION 6: Operation

Activate the Guardian CR2000 by turning the keyswitch out of the OFF position. In the
ADJUSTABLE FAN SPEED position, the airflow can be adjusted by using a flat-blade
screwdriver to turn the recessed FAN SPEED control. In the HIGH FAN SPEED
position, the airflow is fixed at maximum. The key can be removed with the keyswitch in
any position. During operation, the ION OUTPUT and ION BALANCE indicators will
illuminate green to verify the presence of balanced, ionized air. The time required to
neutralize a static charge on an item in the air stream depends upon fan speed. Setting
a higher fan speed reduces time required for neut ral i zation.

When locating the Guardian CR2000, the ionized air stream should cover as much of
the work area as possible. The constant flow of ionized air will maintain items such as
work surfaces, tools, materials and components at very low charge potentials. Charged
items introduced into work area will be neutralized.

SECTION 7: Maintenance

Recommended frequency of cleaning is once a week.

The Guardian CR2000 has been designed for minimal maintenance. The only regular
maintenance suggested is emitter point cleaning. Emitter point cleaning takes only
moments with the built-in point cleaner s . Th e Guar di a n CR20 00 co nt ai ns a balanc i ng
circuit that is inherently self-balancing. This circuit compensates for changes that would
otherwise affect ion balance. Scheduled checking of ion output an d bal anc e sh oul d be
considered to assure quality audit requirements.

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 parking spot. Remove or protect particulate­sensitive product during point cleaning.

Ion Output Check

A charge plate monitor (CPM) such as Simco-Ion’s EA-4 is required to test ion output. A
convenience ground is located near the power outlet for instrument grounding; it
accepts a standard banana plug. If a CPM is not available, a periodic verification
instrument may be used to verify ion output.

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 "spark test" inconclusive.

Ion Balance Check

A charged plate monitor (CPM) such as Simco-Ion’s EA-4 is required to test the unit for
ion balance. A convenience ground is located near the power outlet for instrument
grounding; it accepts a standard banana plug. Allow the unit to warm up for one hour to
ensure the most accurate offset voltage measurement. Offset volta g e should be
measured and checked against the specified ion balance of 0+/-5 volts.

Calibration

Guardian CR2000 5101181_V1 - 09/11

10

The Guardian CR2000 ion output is inherently balanced by design, so there are no
calibration adjustm ents. If, after checking ion balance as outlined above, an unbalance
or offset voltage exists in excess of 0+/- 5 volts, clean the emitters. If the problem
persists, contact Simco-Ion Customer Service at [phone] (USA) or (215) 997-

0590.
