Principle of Operation
Safe Filter Change (SFC) uses a second Clayton HEPA vacuum and a Safe Filter Change Hose to create a downdraft within the primary
vacuum while changing the bag filter.
If this vacuum is used to collect hazardous material, appropriate personal protective equipment may be required.
The bag filter should be replaced when ¾ full.
1. Connect the vacuums.
• Verify the Compressed Air Control valve on both vacuums is in the OFF position.
• Remove all tools and vacuum hoses from the primary vacuum.
• Position the support vacuum with its inlet port facing the SFC port on the primary vacuum.
• Open the inlet port on the support vacuum.
• Insert one metal sleeve of the SFC hose into the inlet port on the support vacuum.
• Open the SFC port on the primary vacuum.
• Insert the other metal sleeve of the SFC hose into the SFC port on the primary vacuum.
• Connect both vacuums to a compressed air source.
2. Remove the power head.
• Unlatch the primary vacuum’s power head from its tank.
•
Slowly lift the primary vacuum power head and attached HEPA filter approximately 1 inch off the tank using the top handle.
• Rotate the support vacuum’s Compressed Air Control valve to the ON position to create the downdraft.
•
Rotate the primary vacuum’s Compressed Air Control valve to the ON position to prevent debris from falling off the HEPA filter.
•
Carefully lift the primary vacuum’s power head and attached HEPA filter off the tank using the top handle.
•
Carefully place the power head on the floor – avoid damaging the HEPA filter.
The primary power head should remain running.
3.
Remove the bag filter.
• Turn a large disposal bag inside out around your arms.
•
Using the disposal bag like a large mitten, grasp the cardboard collar of the bag filter and slide it off the inlet port.
•
The disposal bag should remain between the user and the bag filter.
•
Gently lift the bag filter while drawing the disposal bag down and around the bag filter.
• Gather the neck of the disposal bag and seal the bag closed using tape or ties.
•
Dispose of the bag filter according to company policy.
4.
Install a new bag filter.
•
Unfold and fluff a new bag filter.
•
Push the inlet tube into the hole on the cardboard collar of the bag filter.
• Grasp the sides of the cardboard collar and push it all the way onto the inlet tube.
• Verify the bottom of the collar is past the opening on the underside of the inlet tube.
