Welch Vacuum 2511B-76, C-75, C-76, C-77Aspiration/Filtration - Manual (Page 5)

SECTION 2: INSTALLATION
2.10 Introduction
2.11 This manual has been compiled not only for the care and maintenance of the Welch Aspiration/Filtration
Vacuum System now in your possession, but as a helpful reference and guide to prevent many problems
which may occur if used improperly.
2.20 Unpacking
2.21 Carefully remove the Aspiration/Filtration Vacuum System from the shipping case. Preserve all
paperwork for future reference. If damage has occurred from shipment a claim must be fi led 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
identifi cation. Do not return the pump to the factory without fi lling in the online form for a returned goods
number.
2.30 Pump Mounting
2.31 Rubber feet are attached to the pump. Rubber feet are excellent for applications involving a semi-fl exible
surface such as a bench top; they help to isolate noise and eliminate creeping. All Aspiration/Filtration
Vacuum Systems should be mounted on a horizontal plane.
2.40 Pump Location
2.41 The Aspiration/Filtration Vacuum System should be located preferably in a clean, dry, and well ventilated
area. Please be sure not to block the ventilation holes located on the motor housing. The system should
be placed where the surrounding temperature remains between 10°C and 40°C (50°F and 104°F).
Always check to insure the location chosen is protected from direct or indirect moisture contact.
