Section 2: INSTALLATION
2.1 Introduction
This manual has been compiled not only for the care and maintenance of the Welch Dry Vacuum pump now in
your possession, but as a helpful reference and guide to prevent many problems which can occur if used
improperly.
2.2 Unpacking
Carefully remove the Dry Vacuum pump from the shipping case and unfasten and remove the wooden skid.
Preserve all paperwork for future reference. If damage has occurred from shipment a claim must be filed with the
carrier immediately; preserve the shipping carton for inspection by the carrier. If you are required to
communicate with your dealer or Welch Vacuum be sure to include your order numbers for quick identification.
Do not return the pump to the factory without first calling for a returned goods number.
2.3 Pump Mounting
Rubber feet are attached to the pump. Rubber feet are excellent for applications involving a semi-flexible surface
such as bench tops; they help to isolate noise and eliminate creeping. T h e 2 0 9 0 / 2 0 8 5 vacuum pumps should
be mounted in a horizontal plane.
2.4 Pump Location
The pressure/vacuum pump should be located preferably in a clean, dry and well ventilated area. Please be sure
not to block the ventilation ports located on the motor housing. The pump should be placed where the surrounding
temperature remains between 10oC and 40oC (50oF and 104oF). Always check to insure the location chose is
protected from direct or indirect moisture contact. Welch recommends that the pump be installed at the highest
point within the system to prevent possible water condensate from entering the pump. The pump should be
located as closely to its system in order to utilize it most efficiently.
2.5 Intake and Discharge Provisions
The intake/exhaust connections are NW25 ISO vacuum flange with a 3/8"-18 NPT threaded I.D.
WARNING
The motor is thermally protected and will automatically restart
unexpectedly when the overload device resets.
WARNING
Bursting Hazard
