Your vacuum pump is a precision piece of machinery that will give trouble-free service if used with reasonable
care.
WARNINGS
• DANGER: To prevent explosive hazard, DO NOT pump combustible liquids or vapors with these units.
• WARNING: The motor is thermally protected and can automatically restart when the protector resets.
ALWAYS disconnect power source before servicing.
• IF YOUR PUMP IS EQUIPPED WITH PLASTIC PLUGS IN THE EXHAUST AND/OR INTAKE PORTS,
REMOVE BEFORE STARTING THE UNIT.
• Store pump in original shipping carton with inserts. This will protect pump and keep it clean. It may also
prevent damage due to improper storage.
• Do not, at any time, lubricate any of the parts with oil, grease, or petroleum products nor clean with acids,
caustics or chlorinated solvents.
• Do not operate the pump outdoors in the rain or use near flames.
FACTORSAFFECTINGVACUUMPUMPPERFORMANCE
Your vacuum pump is capable of pulling a vacuum of 740mm Hg (29") at sea level (760mm). For each 300
meters (1000') of elevation the pump's maximum vacuum level is reduced by 25mm (1"). Thus, if the pump is
operated in an area 300 meters (1000') above sea level the maximum obtainable output would be 715mm Hg
(28") of mercury.
Another way to look at the vacuum level is by using the barometric pressure at your location. Your vacuum
pump will pull a vacuum that is about 25mm Hg (1.0") less than the barometric pressure on any given day. If
the barometer reading in your area is 750mm (29.5") you may expect a maximum vacuum pump output of
725mm (28.5"). The barometric pressure varies daily.
SETUPINSTRUCTIONS
1. Locate the pump below the Vacuum furnace. Mounting of the pump above the furnace will cause any water
condensation in the lines to flow back into the furnace.
2. Remove plastic covers from inlet and exhaust ports. Screw in the inlet fitting and exhaust muffler before
operating the pump. The pump may be damaged if covers are not removed.
3. Install feet and tighten using the provided nuts.
4. The pump should be mounted horizontally.
5. Connect the vacuum line from the furnace to the inlet of the pump.
(a) Force the tubing over the inlet fitting.
6. Connect the pump's power cord into the electrical outlet on the back of your DENTSPLY Neytech furnace.
This will allow the furnace to operate the pump when vacuum is called for in a cycle.
