The Ramvac vacuum system utilizes an oil lubricated, rotary vane, positive displacement pump to provide a reliable vacuum source for the dental office. 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 control system. The control is an electronic smart control that utilizes a microprocessor and sensors to monitor the vacuum system and provide alarms or alerts of system needs.

A drip oiling system meters lubricating oil into the pump and is then removed from the airflow by filters inside the oil reservoir, creating a closed loop 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, filtered and recirculated.

DO NOT attempt to operate the vacuum at ambient temperature below 32°F (0°C) or above 104°F (40°C).

1. Verify the vacuum is connected to a dedicated circuit.

2. Verify the vacuum is properly connected to the facility plumbing and a fresh air source.

– Keep area surrounding vacuum pump free of debris.

– Inspect air filters every 1,000 hours.

– Maintain a controlled ambient temperature between 32°F to 104°F (0°C to 40°C). High temperatures will shorten the life of the vacuum pump.

Cleaning Instructions:

1. Always disconnect the power from the equipment prior to cleaning.

2. Some parts/components on the vacuum unit get hot during operation; provide the equipment ample time to cool prior to cleaning.

3. All components can be safely wiped down with a damp cloth, wet with water. Using any cleaners or harsh chemicals to clean this equipment is NOT recommended.

4. Do not heavily wet electrical components.

5. Allow equipment to air dry or dry with clean, soft cloth.

This is a recommended schedule for a vacuum in a clean, dry environment. The control will display the number of hours (remaining runtime) before each maintenance item 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.

CAUTION: 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. The drip rate will vary slightly, depending on the ambient temperature and the oil temperature.

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 ambient temperature is 70°F to 75°F.

4. If the drip rate does not meet specifications, contact a Ramvac technical service representative.

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