Keep vacuum pump clean and free of dirt.
Keep area surrounding vacuum pump free of debris.
Inspect air filters every 1,000 hours.
Maintain a controlled ambient temperature between recommended levels.

CLEANING INSTRUCTIONS

Always disconnect the power from the equipment prior to cleaning.
Some parts/components on the vacuum unit get hot during operation; provide the equipment ample time to cool prior to cleaning.
All components can be safely wiped down with a damp cloth, wet with water.

CLEAN VACUUM SYSTEM LINES

Just before turning OFF (STANDBY) the vacuum each day, rinse lines first with hot water–approximately 1 quart through each high-volume line, and a few ounces through each saliva ejector line.
Aspirate a few ounces of non-foaming, deodorizing dental vacuum line cleaner (SlugBusterTM is highly recommended) through each vacuum line.

CHECK OIL DRIP RATE

Start the vacuum and run for at least 10 minutes.
Look through the sight glass on the bottom of the drippers for drips of oil
Count the number of drips of oil per minute in each site glass. Drip rate should be one to three drops per minute at each dripper when the vacuum unit is thoroughly warmed up, the vacuum setting is 7″ to 7.5″ Hg, and ambient temperature is 70°F to 75°F.
If drip rate does not meet specifications, refer to the USER SERVICE INFO section of the AERAS DRY VACUUM USER MANUAL; otherwise, continue to the next step.
