Introduction
The Meech Model 251 Ion Gun has been designed to effectively eliminate localised
static charges which exist in the work area.
Unpacking and Inspection
The Model 251 Ion Gun 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 Meech Model 251 Ion Gun is a robust, light weight moulded product for use with
the Meech Model 233v3 Pulsed DC Controller. It is suitable for contamination blow-
off and neutralisation of static charges in electronic applications and in cleanroom
environments. It is quick, easy and safe to use. The Model 251 features replaceable
titanium emitters.

Installation and Use
The Model 251 Ion Gun should be connected to the Model 233v3 Pulsed DC
Controller.
Connect each of the male plugs at the end of the HV cables of the Model 251 to the
high voltage sockets of the 233v3 Pulsed DC Controller.
Connect the 6mm air hose from the Ion Gun to the air socket on the rear panel of the
Model 233v3 Controller.
Connect a switched compressed air supply to the air socket on the side of the Model
233v3 Controller, via 6 mm air hose .
Insert the 3.5 mm jack plug on the control cable of the gun to the remote control
socket of the Model 233v3 Controller (It is important to ensure that this connection
remains secure at all times).
Switch on the Model 233v3 Controller. The Model 251 is now ready to use.
The compressed air will be allowed to ow through the Ion Gun as the gun trigger is
depressed. This also activates the high voltage circuit of the Model 233v3 Controller,
energising the emitter pins within the gun nozzle which provide the ionisation to
neutralise static charges on the work-piece. Both the compressed air supply and
ionisation will be switched off when the trigger of the gun is not depressed.
Never point the air ow from the gun towards yourself or any other operator.
Compressed air is dangerous. This device must not be used to clean personnel,
or clothing worn by personnel.
It is important that the compressed air used with the 251 Ion Gun is dry and
uncontaminated. If any water or oil is present in the compressed air line, and is
carried into the nozzle cap of the gun, the operation and condition of the emitter
pins may be seriously affected.

WARNING - High voltages are present in the unit.
Under no circumstances should the unit be opened without rst turning off the
power and isolating the unit by disconnection of the power cord. Operators
must not try to insert ngers or any other object into the nozzle of the Model
251.
Maintenance
The Model 251 is designed with 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 251
disconnected from both the compressed air supply and Model 233v3 Pulsed DC
Controller.
To gain access to the emitter pins, unlatch the nozzle cap from the gun body and
rotate it away. This is done by applying nger pressure to the base of the cap next
to the rotation pivot whilst simultaneously levering upwards the retaining clip which
secures the cap to the body of the gun. 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. Before reactivating
the Ion Gun ensure that the nozzle cap is correctly latched by locating the retaining
clip over its lug and pressing down lightly.
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 Gun 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 Gun
in the presence of sensitive electronics.
Fault Finding
Tests must be completed by a qualied electrical engineer.
If in doubt contact Meech head ofce or your local distributor.
CAUTION: Whilst no danger to personnel exists, it is essential that 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 233v3 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 dif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 Ion Gun 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 Gun 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 Gun 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 Gun has been designed to minimise effects of localised static charges. If your
processing involves generation of considerable static charges, however, you may need
more aggressive equipment. Meech Static Eliminators Ltd manufactures a complete
range of Ionising Blowers, Air Guns, Bars and overhead room systems to meet all
Static Elimination requirements.
