How do low-voltage wiring connections work?

LOW-VOLTAGE REMOTE SWITCHING

Maximum wire length for 18-gauge wire is 500 feet. Low-voltage remote switching is used to turn the system on and off from a remote location. Ramvac vacuums are manufactured to continuously run throughout the workday. To conserve power, turn off vacuum if it will not be needed for an hour or more. Power the vacuum off at end of day. The tank will drain only when no vacuum is present; the vacuum must be turned off at least once per day.

Illuminated Remote Panels:

Switch light is steady on when system is running normally.

Switch light flashes slowly for maintenance.

Switch light flashes rapidly for moisture in filtrols, water in exhaust or low oil level.

Non-Illuminated Remote Switches:

Non-illuminated switches provide no indication for system status.

LOW-VOLTAGE AUXILIARY DEVICE CONNECTION

Maximum wire length for 18-gauge wire is 500 feet. Low-voltage auxiliary device connection is used to connect an alternate controller driven compressor, vacuum or master water control valve to this vacuum. The auxiliary power state will match the power state of this vacuum (ON/STANDBY).

NOTE: Pins are dry contact (no voltage output).


What is the initial startup procedure for a three-phase installation?

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.


How does the Ramvac dry vacuum system work?

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.

One reason your Ramvac vacuum will outlast every other dental vacuum system is its lubrication system. 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.


How do I get the system started?

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

The vacuum is easy to operate and maintain.

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.

Check Air Filters Every 6 Months or 1,000 Hours*
Replace Air Filters, Change Oil, Check/Replace Oil Filter Element, Check V-belt Annually or Every 2,000 Hours*

*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.


How do I clean the vacuum system lines?

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. Cleaner should have these qualities: 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.


How do I check the oil drip rate?

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.

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.

1. ALWAYS determine and correct the cause of a moisture in pump intake alert. Trying to operate the vacuum while there is moisture in pump intake can damage equipment and void the warranty.

2. Clear the moisture:

a. Allow the separating tank to drain.

b. Lift off the vacuum controller and remove main air filter. Clean out any remaining moisture.

c. Remove moisture sensor (by twisting and pulling down) and dry the contacts.

d. Install moisture sensor, main air filter and vacuum controller.
