Introduction
The Meech Models 271 and 272 Flexible Ion Nozzles have been designed to
e󰀨ectively eliminate localised static charges which exist in the work area.
Unpacking and Inspection
The Model 271/272 Flexible Ion Nozzle has been carefully packed at the factory
in a container designed to protect it from accidental damage. Nevertheless, we
recommend careful examination of the carton and contents for any damage. If damage
is evident, do not destroy the carton or packing material and immediately notify the
carrier of a possible damage claim. Shipping claims must be made by the consignee to
the delivering carrier.
Description
The Model 271/272 Flexible Ion Nozzles are compact , “hands-free” ionisers, designed
for repetitive cleaning tasks. They are powered by the Meech Model 233 Pulsed DC
Controller. They are suitable for electronic and cleanroom environments and are quick
to install and easy to use. Both Models feature replaceable titanium emitters.
The Models 271 and 272 are designed to be free standing. However, each features
a base plate that o󰀨ers 4x4mm xing holes to enable the unit to be rmly xed to the
work bench or vertical surface, if required.

Installation
The Model 271/272 should be connected to the Meech Model 233 Pulsed DC
Controller.
Connect each of the plugs on the end of the cables of the Model 271 or 272 to a high
voltage socket of the 233 Pulsed DC Controller.
Air connection for the Model 271 Flexible Ion Nozzle.
Connect the compressed air supply directly to the Model 271, via 6 mm air hose .
A local compressed air shut-o󰀨 valve such as a foot switch should be installed (not
supplied). The compressed air supply should be regulated to 30 Psi(2 Bar). Maximum
operating pressure is 100Psi (7 Bar): optimum operating pressure will be application
dependent.
Switch on the Model 233 Controller and operate the air supply shut-o󰀨 valve. The
Model 271 will now be operational and ready to use. The air supply and ionisation will
both remain on until the shut o󰀨 valve is closed and the Controller is switched o󰀨.
Air and HV Switch connection for the Model 272
Flexible Ion Nozzle.
The Model 272 is supplied with a pneumatic foot pedal specially modied to include
an integrated micro switch. The compressed air supply should be routed through the
air tting on the foot pedal via standard 6 mm air hose and then to the Flexible Ion
Nozzle.
The compressed air supply should be regulated to 30 Psi(2 bar). Maximum operating
pressure is 100Psi(7 Bar): optimum operating pressure will be application dependant.

The 3.5 mm jack plug on the foot pedal control cable should be inserted into the
remote control socket on the rear of the Model 233 Controller. As the foot pedal is
depressed the air is allowed to ow to the Flexible Ion Nozzle. Depression of the foot
pedal also activates the micro-switch which turns on the high voltage circuit of the 233
Controller. The Model 272 Flexible Ion Nozzle will only emit ions when the foot pedal
is depressed (ie ON).
WARNING - High voltages are present in the unit.
Under no circumstances should the unit be opened without rst turning o󰀨 the
power and isolating the unit by disconnection of the power cord of the 233.
Operators must not try to insert ngers or any other object into the nozzle of the
Model 271 or 272.
Maintenance
Models 271 and 272 feature replaceable titanium emitter pins. These should be
inspected periodically (typically every 30 days).
Inspection of the emitter pins must only be carried out with the Model 271 or
272 disconnected from both the compressed air supply and Model 233 Pulsed
DC controller.
Remove the nozzle cap by unscrewing the cap from the nozzle body. The emitter pins
will now be accessible. If the pins appear dirty they should be cleaned using a swab
and isopropanol. The emitter pins must be allowed to dry before the cap is replaced
and the unit is switched back on.
If the pins are worn and require replacement, the pins should be removed using a pair
of round nose pliers and replacements tted. Replacement pins are available from
Meech, item code A-200-EMITP-10/1.0.
The exterior of the Flexible Ion Nozzle should be kept clean by wiping with a damp
cloth.

For Best Results
1. Keep the target area clear and free from obstructions to the ion ow.
2. Keep the work area clear of all static generative materials.
3. Use only approved static control grounding methods and material handling
equipment.
4. By properly using ionised air, all static potentials in the work area are
greatly reduced, even when humidity levels decrease.

Calibration And Balance Verication
Balance verication should be checked in accordance with the ESD protection
Standard ANSI-EOS/ESD-S3.1-1991.
Remember
It is important to verify calibration after any adjustments and before using your Ion
Nozzle in the presence of sensitive electronics.
Fault Finding
Tests must be completed by a qualied electrical engineer.
If in doubt contact Meech head o󰀩ce or your local distributor.
CAUTION: Whilst no danger to personnel exists, it is essential than any high voltage
ionising equipment makes no contact with water or water based uids. Should such an
event occur, disconnect immediately and return equipment to Meech for water damage
assessment.
Cable Plugs
Please note that, on leaving the factory, the brass ends of the cable plugs are
congured to a standard size for tment into the power sockets of the A233/232 Pulsed
DC Controller. Meech has found that occasionally during transportation and handling
the ends of the plugs can become slightly mis-shaped which may cause di󰀩culty with
their location into the power sockets.
If you nd this to be the case, then (1) if the plugs are too tight, you should lightly
pinch together the two halves of the brass end of the plug with a pair of pliers, or (2) if
the plugs are too loose, you should gently open out the slot in the brass end with the
blade of a screw-driver or knife.

Repairs and Warranty
Your Flexible Ion Nozzle is warranted by Meech Static Eliminators Ltd to the original
purchaser against defects in material and workmanship for one year after purchase.
Should any malfunction occur, please return the ioniser directly to Meech or to your
distributor. All products returned to the factory MUST be accompanied by a return
authorisation number and must be shipped prepaid. Meech Static Eliminators Ltd.
liability under this warranty is limited to replacing or repairing any unit returned by the
purchaser, that has not been subject to misuse, neglect, repair, alteration or accident.
In no event shall Meech Static Eliminators Ltd be liable for collateral or consequential
damages.
For prompt service, ship the unit to the factory with the return authorisation number
shown clearly on the label. Be sure it is well packed in a sturdy carton with shock
absorbing material. Include a note stating the nature of the problem as specically as
possible, and also include instructions for returning the Ion Nozzle to you. Meech will
pay one-way return surface shipping costs on any repairs covered under the warranty.
Field repairs should not be undertaken during the warranty period. Repair attempts by
unqualied personnel will invalidate the warranty.
Your Flexible Ion Nozzle has been designed to minimise e󰀨ects of localised static
charges. If your processing involves generation of considerable static charges
however, you may need more powerful equipment. Meech Static Eliminators Ltd has
available a complete range of Ionising Blowers, Air Guns, Bars and overhead room
systems to meet all your Static Elimination requirements.
