VACUUM RELIEF VALVE SAFETY — CONTINUED
Testing the Remote-Operated Vacuum
Relief Valve
The following test should be done every time the
pendant is plugged in or every two hours of
operation, whichever is more frequent.
1. Visually inspect the pendant cord, electrical plug, and
control switch for damage. Repair or replace as
needed.
2. If the pendant is not currently plugged in, insert the
electrical plug on the end of pendant cord into the
socket located at the front control panel or the
curbside control panel.
3. Start up the vacuum pump per operating procedure
in manual.
4. With unit at full vacuum, press the VENT OPEN
button on the remote and verify that the vacuum relief
door has opened. Press the VENT CLOSE button
and verify that the vacuum relief door has closed.
5. After testing, shut down the vacuum pump per
operating procedure.
If vacuum relief valve is not working properly,
personnel should not be allowed to work at end
of vacuum hose due to possible personal injury
or death. Repair or replace valve before operating
vacuum pump.
Never work beyond the distance from the truck
that the wireless remote control was previously
tested at. Failure to comply could result in
equipment not properly operating.
