Air Supply
a. The air supply must be clean and dry. A 5 micron coalescing lter is
recommended. The Meech guarantee does not cover damage due to water
or oil in the air supply.
b. Reduce the air supply to the lowest pressure which achieves the required
results. Excessive air is wasteful and also dilutes the ionisation
unnecessarily.
c. The female thread for the air tting is 1/4 BSP.

Caution: When used in conjunction with a model 920 HER ionising bar this
equipment will give an electrical shock if the pins are touched. The following
procedure must be followed.
The supply voltage of the power supply must be interlocked with the ON/OFF
control of the machine to which the equipment is tted.
This will ensure that whilst the machine is switched off and thus operatives may
gain access to the machine and our equipment there will be no danger of operatives
receiving shocks from our equipment.
It is assumed that normal safety barriers are in place on the machine to ensure that
operatives are unable to access the machine and hence our equipment whilst the
machine is switched ON.
