Technical Description:
The RAMVAC Bison Vacuum System utilizes an oil lubricated, rotary vane, positive displacement pump to provide a reliable vacuum source for
the Dental ofce. This vacuum unit is intended solely for the removal of dental waste material from the oral cavity during dental procedures.
The pump is powered via a belt drive system by an electric motor that is controlled by the S2 Control System. The S2 Control is an electronic,
smart control that utilizes a microprocessor and sensors to monitor the vacuum system and provide alarms or reminders of system needs.
A drip oiling system meters lubricating oil into the pump and is then removed from the airow by lters inside the oil reservoir, creating a closed
loop system.

Maintenance
Cleaning the Vacuum System
Clean vacuum lines daily. Just before turning off the RAMVAC, rinse vacuum lines rst with hot water -- approximately one quart
through each high volume line and a few ounces through each saliva ejector line. Then aspirate a few ounces of a dental vacuum
line cleaner through each vacuum line. SlugBuster
Foam may cause a Moisture in Filtrols Fault (See “Moisture in Filtrols Fault”) and shut down
· Non-Foaming:
De-Odorizing:
the Bison. Avoid interruptions by insuring 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 an appropriate vacuum line
cleaner, such as SlugBuster, through the lines.
For overhead plumbing, be sure to allow air to follow liquids before closing vacuum valves.
Clean treatment room solids separators routinely. Check the treatment room solids separator routinely and clean when dirty.
Cleaning Unit
1. Always disconnect the power from the equipment prior to cleaning.
2. Some parts on the vacuum get hot during operation. Provide the unit ample time to cool prior to cleaning.
3. All components can be safely wiped down with a damp cloth, wet with water. We do not recommend using any
cleaners or harsh chemicals to clean this equipment since their potentially harmful effects have not been evaluated.
4. Do not heavily wet electrical components
5. Allow equipment to air dry or dry with clean, soft cloth.
TM
is highly recommended. Cleaners should have these qualities:
Inspect air lters often. The Main Air Filter is accessed
by lifting the Vacuum Controller up and out of the Filtrols.
Replace Filters every 2000 hours or when visibly dirty.

Lubricating System Components
One reason your RAMVAC will outlast every other dental vacuum system is its “Lubrication System”. The “Lubrication System”
supplies oil drop by drop through “Drippers” to the pump. Used oil is discharged back into the Oil Reservoir as a mist, separated
from the exhaust, ltered and recirculated.
Change oil every 2,000 hours.

Oil Change
“ Change Oil” is displayed on the S2 Electrols every 2000 hours .
Procedure:
1. Drain Used Oil
· Place empty oil container (minimum 6 quarts) under oil drain tube
· Open oil drain valve. When oil stops draining, close valve.
· If you see water in the oil, contact your dealer or RAMVAC.
2. Check Oil Filter
· Unscrew oil lter and remove lter element.
· Normally your oil lter element will be clean. If dirty, contact your dealer or RAMVAC.
· Re-assemble oil lter. Hand tighten only.
3. Add Fresh Oil
· Remove oil ller cap.
· Add 5 quarts Mobil 1, 15w50. Check Oil Fill Level at sightglass and add or drain oil accordingly. (see pg. 10).
· Use only recommended oil, available locally and also available from RAMVAC.
· Securely install oil ll cap.
· Check oil drip rate. See “Check Oil Drip Rate”
· Dispose of used oil at a gas station or lubricant recycling station.
4. Reset “Change Oil”
· From “Change Oil” screen press and hold the reset button for 10 seconds.
Check Oil Drip Rate
Check the drip rate at the “Dripper Site Glass” after the rst week of operation, after every oil change, and every time
the 1000 hour Filter Maintenance displays.
Drip rate should be 1 to 3 drops per minute at each “Dripper” when the Bison vacuum unit is thoroughly warmed-up, the
vacuum setting is 7” to 7.5” Hg, and ambient temperature is 70ºF to 75ºF.
Stronger vacuum and/or elevated temperature will increase the drip rate. Weaker vacuum and/or cooler temperature
will decrease the drip rate.
If the drip rate is not as specied, contact your dealer or RAMVAC.
Check V- Belt
Inspect V-belt for wear every 2,000 hours. Replace if cracked or frayed.
V-belt tension will not normally need adjustment. However, tension will need adjustment if belt
squeak at start up.
Contact RAMVAC for information.
S-Type Exhaust Filter
Band
Cover
Bolt
Check lter element every 2,000 hours.
Loosen band and remove cover, then remove bolt to inspect element inside surface for dirt build up.
Replace lter element when dirt is visible on inside surface.
Elements can be expected to last 5 to 10 years if oil is uncontaminated by liquids and particulates.
Unusually dusty environments, aspirating unusual quantities of air abrasives or other particulates, or
pump ooding can dramatically shorten the element’s service life.
Failure to maintain lter element can increase amperage and possibly trip motor overload.
