2.11 Introduction
Intended use of the proprietary oil-less vacuum system consisting of a vacuum blower in
combination with a PTFE diaphragm pump providing deep dry vacuum for chemical resistant
applications.
This manual has been compiled not only for the care and maintenance of the Chemstar Dry
now in your possession, but as a helpful reference and guide to prevent many problems which
can occur if used improperly.
2.12 Unpacking
Carefully remove the Chemstar Dry from the shipping case. Handles are provided on the lower
front and back of the unit to assist in carrying, lifting and removing from the carton. 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 obtaining
returned goods authorization. *See “Service & Support” on www.welchvacuum.com.
2.13 System Mounting
Rubber feet are attached to the bottom of 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. The Chemstar Dry system must be positioned with feet on a fl at horizontal surface.
