IMPORTANT: To ensure that this equipment reaches you in first class condition, protective coatings, rust inhibitors
etc., have been used. Flush all equipment through with a suitable solvent before use to remove these agents from
the material passages.
The AGN gun operation is different to models that have a needle valve to control the coating material flow. To shut
coating material flow off, air pressure must be maintained on the diaphragm (6) to seal against seat (5). The simplest
method of gun control is to use a normally open three way valve for the diaphragm air supply 'A' and a normally
closed three way valve for the atomising air supply 'B'. These valves can be automatically or manually operated.
To prevent unatomised coating material spoiling the finish the sequence of control valve operation should be;
To Spray 1.
2.
Stop spraying 3.
4.
The timing of these valve operations will depend on the speed of gun operation required, for some applications the
atomising air supply could be continuously ON and the diaphragm air control valve operated when spray is required.
Caution: In case of an air supply failure it is recommended that a fail-safe valve is fitted to the coating material
supply to prevent accidental spillage.
Separate filtered regulated air supplies are required for atomising and diaphragm operation.
Mount the gun on a 12.5 mm (1¼2") diameter rod and secure with screw (7).
