TROUBLESHOOTING PROCEDURES
PROCEDURE 1
Blocked Fluid Passage In Diaphagm Pump
If the pump sounds like it is working but liquid does not flow, clear the
fluid passage as follows:
•
Remove suction tube from the pail and blow air at 60 PSI into the
INLET Sovent Hose (see diagram). Start the pump. This procedure
may have to be repeated several times. If this procedure does not
help, blow some water into the suction hose using a spray gun, wait
one minute and start the pump. This procedure may have to be
repeated several times. If this procedure does not work, the pump
must be replaced.
If you need to replace the pump call your local dealer. The warranty on
the diaphragm pump is two years from date of purchase.
This procedure will also clear a blockage in the fluid line for the wash gun.
PROCEDURE 2
Blocked Air Passage In Diaphragm Pump
If there is a steady hissing sound and the pump is not cycling, the spool
valve has stalled due to a blocked air passage. Follow the procedure
below to clear the blockage.
•
Connect a blow gun to an 60 PSI source. Locate the blue hose that
extends from the air exhaust port of the diaphragm pump. Use a
blow gun to blow air into the open end of this hose. Start pump. If
the procedure is successful, the pump will start working. The proce-
dure may have to be repeated several times. If this procedure does
not work, replace the pump.
•
Cause:
Contaminants in the air supply (water, oil, solid particles etc)
•
Preventative Action:
If necessary, install an Airline (Moisture) Filter.
PROCEDURE 3
Blocked Passage in Air Line
The components in the air line are the 1)
diaphragm pump, 2) air valve and 3)regulator.
To troubleshoot a component:
1) Disconnect the air line to the first component using the quick disconnect.
2) Start the pump and check for presence of positive air pressure in the air line. If there is ample posi-
tive air pressure, replace the component.
If air pressure is absent, there is a faulty component down stream. Reconnect the air line and check
the operation of the next component downstream by following steps 1 and 2 above.
