Respect the minimal distance between the pump and the walls (Refer to Dimension drawings on page 22). ▪ Correct process lines sizes must be used to prevent restrictions and resulting pressure drops.
-
Page 34: Electrical Connections
A35104880_B - Installation ▪ When pumping condensible vapours and particulates, more frequent fluid changes are required to maintain pump life. Contact us about types and styles of filtration units. ▪ Make sure there is no backpressure in the exhaust line of the vacuum pump. Vacuum pumps are not specifically designed to compress exhaust gas above atmospheric pressure. -
Page 35: Pictographs
A35104880_B - Installation ▪ For pumps with a single-phase motor, the pump should be connected to a standard wall socket, a 16 A rated protection is necessary (fuse or breaker). The motor has a "Klixon" overload protection element which looks like a red push button that must be manually reset after an overload trip. -

Page 42: Adjustments And Servicing Procedures
A35104880_B - Adjustments and servicing procedures 7. Adjustments and servicing procedures 7.1 Drive motor On nES100 - nES750 (nES40 - nES65 do not have motor bearings) the motor bearings must be changed every 20,000 hours. Check recommendations on the motor's website. If installed, remove the motor condensate drain plug yearly. - Page 43 A35104880_B - Adjustments and servicing procedures nES630, nES750 Tools required: Tubular box wrench 16 mm. When the exhaust filter elements are clogged, the integrated bypass opens and the filters are bypassed. Oil mist at the exhaust and high oil consumption are signs that the exhaust filters are clogged.
