Introduction
The Meech Model 261v2 Ion Nozzle has been designed to e󰀨ectively eliminate
localised static charges which exist in the work area.

4
Unpacking and Inspection
The Model 261v2 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.
General
The Model 261v2 Ion Nozzle is a small, robust ionising nozzle. Available in several
versions it provides an ionised airow for cleaning and neutralising static charges.
It is powered by a Meech Model 233v3, 977CM or 977v3 Pulsed DC Controller. It is
suitable for industrial, electronic and cleanroom environments and is quick to install
and easy to use. The Model 261v2 features replaceable titanium emitters.
It is available in various versions with di󰀨erent inlet and outlet congurations. Drawings
of these versions are available from the Meech website.

Installation
The Model 261v2 should be connected to the 233v3, 977CM or 977v3 Pulsed DC
Controller. Connect each of the male plugs on the cable of the Model 261v2 to a
high voltage socket on the Pulsed DC Controller. In the case of a multiple nozzle
installations, use the appropriate pair of high voltage splitters.
Air Supply
Depending on which model of 261v2 is being used it may be installed with
compressed air or pumped air.

6
Compressed Air
Connect your air supply directly to the Model 261v2 using 6mm push t hose. A local
compressed air shut-o󰀨 valve should be installed (not supplied). For most applications,
the compressed air supply should be regulated to 30 psi (2 bar). Maximum operating
pressure is 100psi (7 bar).
Pumped Air
Versions of the nozzle with ¼” bsp inputs can be used with low pressure pumped air.
Ensure that any ttings used have as side a bore as possible, to maximise the air-ow.
Interlocking of High Voltage
We recommend interlocking the state of the high voltage output to the running state
of the machine. This can be achieved by switching the power supply to the Pulsed
DC controller or by using the remote on/o󰀨 input built into all Meech Pulsed DC
controllers. See the relevant operating manual for more information.
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.

Remember
It is important to verify calibration after any adjustments and before using your Ion
Nozzle in the presence of sensitive electronics.

Maintenance
Cleaning your Meech Ioniser
Ionisers require periodic cleaning. During normal operation, dirt will build-up on
the emitter pins and upon the body of the ioniser. This will cause a reduction in
performance.
Ionising nozzles may need their outlet cap to be removed to allow access to the pins.
They should be checked for any oil or water contamination that might indicate a poor
quality air supply that could cause permanent damage.
Typically, weekly cleaning is su󰀩cient. However, equipment used in some heavy
contamination areas, such as gravure printing or where plastic fumes are present, may
require daily cleaning.
Before cleaning, ensure that the equipment is switched o󰀨.
Emitter pins can be cleaned very e󰀨ectively with a brush. A dry toothbrush is ideal.

9
Ionisers will need periodic wiping to clean grey deposits from the surface of the bar. A
cloth moistened with a small amount of IPA or methylated spirits is recommended.
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 Ion Nozzle should be kept clean by wiping with a damp cloth.

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 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.
10

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 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 Ion Nozzle 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.
Important
Your Ion Nozzle has been designed to minimise e󰀨ects of localised static charges.
If your processing involves generation of considerable static charges, however, you
