1) Set Power Switch to the OFF position and monitor Air Pressure Gauge to
be sure air pressure drops to 0. Allow an additional 20 seconds of bleed
off time after the gauge reading reaches 0.
Retract the plunger of Abrasive Pinch Valve to facilitate changing Pinch
Tube. Disconnect Air in Hose. Turn Power Switch to ON for a few
seconds and then back to OFF.
2) Remove top block from assembly by removing the two screws. Remove
worn pinch valve tube and fittings from bottom block. Remove tube from
fittings and carefully insert the new pinch valve tube between the fittings.
Carefully place the new pinch valve and fittings into the bottom block
indentation.
3) Carefully replace top block, again making certain that the tube and fittings
align with the indentations in the top block. Secure top block in place with
attaching hardware.
4) Turn Power Switch ON, depress Reset Switch and check for proper
operation and air leaks.
E. MAIN AIR SOLENOID VALVE
The Main Air Solenoid Valve controls the flow of air into the unit. The valve is
either open, providing airflow when the unit is ON or closed stopping the flow
when the unit is OFF. The valve is not field repairable. Replace if it
malfunctions.
F. REGULATORS
The unit is provided with two regulators; one for the Pinch Valves and one for
the main air flow. The regulators are not field repairable. In the event of
malfunction, replace.
G. AIR PRESSURE GAUGE
The Air Pressure Gauge is not field repairable and should be replaced with a
new one if it malfunctions or fails to operate.
H. POWDER FLOW RHEOSTAT
The Powder Flow Rheostat adjusts the magnetic coil voltage level. Check
electrical connections at the rheostat, if it malfunctions. If this is not the
problem then check operation as follows:
1) Connect a voltmeter across the input to the magnetic coil of the Vibrator.
2) Turn the Powder Flow Knob completely counter clockwise.
