5. Place a new gasket on the end plate; secure the end plate
and valve body using six (6) socket cap screws.

socket cap screws and a new O-ring.
Reinstalling Lower Valves
1. Replace the O-ring in the valve body.
2. Position the valve back on the vacuum power unit. Tighten
the set screws that secure the valve to the blower outlet.
3. Insert the silencer into the valve body, and bolt it to the
base at the bracket. Screw the vertical silencer back on.
4. Reconnect the compressed air line to the valve.
5. Reconnect the valve to the T-Y tube using the radiator hose
and hose clamps. Tighten the hose clamps.
5-5 Maintaining Vacuum Receivers and Filter/
Receiver Combinations
• Clean the vacuum receiver filter cartridges as needed. Blow
clean with compressed air. Blow out from the inside for best
results. If the screen becomes bent or warped, or the gasket
becomes worn, replace it to prevent material carry-over to the
VFC filter chamber.
• Clean and inspect the gasket. Replace it if it is worn.
• Invert SR Series vacuum hoppers onto their flat covers for
easier maintenance.
• If the optional SR Series vented internal sequencing valve is
installed, make sure you remove compressed air prior to
servicing.
• If optional supplemental cloth filter bags are being used,
periodically inspect for wear and fouling. Clean or replace as
necessary.
