9. Water and Sewer Facilities at the Installation Site (Water-cooled models only)
Make sure the water supply is connected and open. Piping supplied by the user should be at least equal to the
connections provided on the vacuum pump. Cooling water should be clean and cool. Scale forming or corrosive
water will shorten the life of water-cooled coolers. If there is any doubt about the condition of the water, have it
analyzed. It may be necessary to add a water treatment system and/or revise the cooling system. Sewer facilities
should be readily
accessible to the installation site and meet all the requirements of local sewer codes, plus those of
the vacuum pump.
Make absolutely sure water inlet and discharge connections are correct.
NOTE:
The water temperature-regulating valve is located in the discharge water line.
! WARNING
Relieve vacuum pump and system vacuum by opening the appropriate manual relief
valve prior to servicing. Failure to relieve all system pressure could result in death,
serious injury and property damage.
10. Induction Filtration System
Extreme care must be taken in selecting a proper induction filtration system for the vacuum pump. Liquids, solids,
and abrasive powders can result in short life or mechanical failure of the bearings, erosion of the rotors, plugged
fluid filter and/or separator element, short life of the fluid seal, corrosion of internal parts and motor overload. Use a
vibration isolator and support all piping correctly. Piping should be at least as large as the inlet valve opening. The
piping must be leak free and absolutely clean after fabrication.
All connections to the vacuum pump must be tight. Air leakage into the vacuum system lessens the vacuum pumps
ability to draw down to a base level of vacuum and increases energy consumption.
