Ramvac Fully Synthetic Vacuum Pump Oil is recommended. Prior to performing maintenance, take precautions to reduce contact with infectious substances.

1. Remove oil fill cap.

2. Add oil and check the oil fill level at the sight glass. DO NOT OVERFILL. The oil level should be even with the head of the red arrow.

3. Securely install the oil fill cap.

4. Check the oil drip rate as described in the manual.

5. Dispose of any used oil at a gas station or lubricant recycling station.

1. Remove vacuum controller from top of filtrols.

2. Remove main air filter from inside filtrols.

3. Run motor for one (1) second with hand in filtrols.

4. If air blows into filtrols from pump:

a. Reverse any two motor power lead wires at motor starter overload relay (2T1, 4T2 or 6T3).

b. Clean any oil out of filtrols.

c. Return main air filter and vacuum controller to their places.

5. If air sucks out of filtrols towards pump, return main air filter and vacuum controller to their places.

The Ramvac vacuum system uses an oil lubricated, rotary vane, positive displacement pump. The pump is powered by a belt-driven electric motor, controlled by an electronic smart control that monitors the system and provides alerts.

The system’s longevity is due to its lubrication system. A drip oiling system meters oil into the pump, which is then removed from the airflow by filters inside the oil reservoir, creating a closed loop. The used oil is discharged back into the reservoir as a mist, separated, filtered, and recirculated.

CAUTION: 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.

3. Check oil level.

4. Put the antenna (located on the right side of the control panel) in the upright position.

5. Push the control panel power switch to the ON position.

6. To switch the vacuum from STANDBY to ON, press the orange STANDBY switch on the HOME screen. The switch will turn green and display ON.

7. The vacuum installation is complete.

Follow the recommended PREVENTIVE MAINTENANCE SCHEDULE.

Rinse vacuum lines daily with the recommended quantity of liquid.

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 of 32°F to 104°F (0°C to 40°C). High temperatures will shorten the life of the vacuum pump.

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 schedule is for a vacuum in a clean, dry environment. Any site other than specified will decrease maintenance time exponentially.

*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.

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. After surgical procedures, aspirate a few ounces of cleaner. For overhead plumbing, 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 ambient and 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 rate should be one to three drops per minute at each dripper when the 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. Use of personal protective equipment (gloves) is recommended.

1. On the control panel, go to the Technical screen and press MAINTENANCE MODE to enable it. This disables remote switching and puts the system in standby mode.

2. To replace the CONTROLLER air filter (all models):

a. Remove the retaining nut from the top of the controller air filter.

b. Lift the controller air filter over the teepee and discard.

c. Replace with new controller air filter.

d. Re-attach retaining nut.

3. To replace the MAIN air filter:

a. Without removing any bolts or nuts, lift the vacuum controller off the vacuum pump.

b. Remove main air filter:

Models RV5, RV7, RV10 and RV12: Lift the main air filter straight out of the filtrols and discard.

Model RV4: Slide the main air filter to the access hole; lift filter out of the filtrols and discard.

c. Replace with new main air filter.

d. Place vacuum controller into filtrols.

After replacement, reset the runtimes for the filters via the control panel’s service menu.

Change oil annually or every 2,000 hours. Use of personal protective equipment (gloves) is recommended.

1. Operate the vacuum pump until the oil reservoir is warm to the touch, then turn the vacuum pump OFF.

2. On the control panel, go to the Technical screen. Press and enable MAINTENANCE MODE. This disables remote switching and puts the system in standby mode.

3. Drain used oil:

Place an empty oil container (minimum six quarts) under the oil drain tube.

Remove rubber plug and open drain valve. When oil stops draining, close valve and replace rubber plug.

4. Add fresh oil:

Use only recommended oil.

Add the correct quantity of oil based on the model (RV4: 3 quarts; RV5, RV7, RV10, RV12: 5 quarts).

Check oil fill level at sight glass. Do not overfill.

Securely install oil filler cap.

5. Check oil drip rate.

6. Dispose of used oil at a gas station or lubricant recycling station.

7. Reset runtime for oil change via the control panel service menu.

Check the oil filter element annually or every 2,000 hours. Replace if dirty.

1. On the control panel, enable MAINTENANCE MODE.

2. Unscrew oil filter assembly and remove filter element.

3. If element is dirty, replace with a new one.

4. Reassemble oil filter; hand tighten only.

5. If replaced, reset runtime for the oil filter via the control panel service menu.

Inspect V-belt for wear every 2,000 hours. Replace if frayed or cracked. V-belt tension will not normally need adjustment; however, if the belt squeaks at start-up, contact Ramvac technical support.

1. On the control panel, enable MAINTENANCE MODE.

2. Disconnect power at the disconnect box or breaker.

3. Remove belt cover screw(s), then remove belt cover.

4. Inspect belts for frays or cracks. If belts need to be replaced, see service instructions for complete installation.

5. Re-attach belt cover with screw(s).

6. Restore mains power.

7. If belts were replaced, reset runtime for the belt via the control panel service menu.

The S-type exhaust filter is standard on RV10 and RV12 models and optional on RV4, RV5, and RV7 models. Inspect the filter element every 2,000 hours.

1. Loosen the band and remove the cover, then remove the bolt to inspect the inside surface for dirt build-up.

2. Replace the filter element when dirt is visible on the inside surface.

Moisture in the pump intake is not normal and occurs if liquid or foam is present. Trying to operate the vacuum with moisture in the pump intake can damage the equipment and void the warranty.

TO AVOID MOISTURE IN PUMP INTAKE

1. Aspirate only non-foaming substances. Check vacuum line cleaners by shaking a mixture in a glass container. Do not aspirate cold disinfecting solutions and ultrasonic solutions.

2. Rinse lines with a known quantity of water.

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

TO CORRECT MOISTURE IN PUMP INTAKE
