*The control will display the number of hours (remaining runtime) before each maintenance item is due. If a lighted remote switch is installed, it will also flash the light, indicating that maintenance is due.

Clean the vacuum lines daily. Just before turning off the vacuum, rinse lines first with hot water—approximately one (1) quart through each high-volume line and a few ounces through each saliva ejector line. Then aspirate a few ounces of dental vacuum line cleaner through each vacuum line. SlugBuster vacuum line cleaner is highly recommended. The cleaner should be non-foaming and deodorizing.

Foam may cause a “Moisture in Pump Intake (Filtrols)” alert. Avoid interruptions by ensuring your cleaner is truly non-foaming. Test by shaking the mixed solution. True non-foamers will be bubble-free.

Cleaning requirements will vary according to activity. After surgical procedures, aspirate a few ounces of vacuum line cleaner through the lines. For overhead plumbing, be sure to allow air to follow liquids before closing vacuum valves. Check the treatment room solids separator routinely, and clean when dirty.

Check the drip rate at the dripper site glass after the first week of operation, after every oil change, and every time the 1,000-hour filter maintenance displays.

1. Start the vacuum and run for at least 10 minutes.

2. Look through the sight glass on the bottom of the drippers for drips of oil.

3. Count the number of drips of oil per minute in each site glass. The 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 the ambient temperature is 70°F to 75°F.

Inspect air filters every 6 months or 1,000 hours. Replace filters every 2,000 hours or when dirt is visible. Use of personal protective equipment (gloves) is recommended.

1. On the control panel, go to the Technical screen and enable Maintenance Mode. This disables remote switching and puts the system in standby.

Moisture in the pump intake (filtrols) is not normal. This fault occurs if liquid or foam is present in the pump intake.

TO AVOID MOISTURE IN PUMP INTAKE:

1. Aspirate only non-foaming substances. Be sure to check vacuum line cleaners (even those that say “non-foaming”) by shaking a mixture in a glass container.

2. Rinse lines with a known quantity of water.

3. Do not exceed your separating tank’s capacity.

TO CORRECT MOISTURE IN PUMP INTAKE:

Prior to performing any maintenance, proper precautions should be taken to reduce the possibility of contact with infectious substances.
