Thanks for purchasing the Universal Vacuum Booster. 

This unit draws up to 11 amps of power so you should always try to plug into a dedicated electrical circuit. Be sure to check ground pin on male electrical plug to make sure it is in place. Only use grounded electrical outlets. Do not suck foam or water through vacuum motor. Do not transport cleaning machine with vacuum booster attached. Always remove booster while transporting machine or while transporting to and from the job site inside inside of your service vehicle. Do not plug into an electrical outlet that is shared by another power cord with the cleaning machine. Always keep the vacuum intake screen clean by just wiping off with your hand or towel (do not hose off - clean dry) 

If your machine uses a different style vacuum lid, you will need to replace your old lid with the black outer ring provided. You can re-use the same screws that are currently holding down your existing vacuum lid ring for the new ring. Be careful not to over tighten for you are just screwing into plastic or fiberglass. You can also place a small bead of silicone around the underside of the vacuum ring before assembly. You can also fill any unused screw holes with silicone to make sure you do not have any vacuum leaks. 

Unit comes with a one year parts warranty. Warranty excludes shipping and labor. If you need help with a warranty issue, please email info@steambrite.com with your invoice number along with an explanation of what you think is wrong with the unit.
