1. INTRODUCTION
CONGRATULATIONS on your purchase of a new C-Flange
Mechanical Vacuum Booster from Tuthill Vacuum & Blower
Systems. Please examine the booster for shipping damage,
and if any damage is found, report it immediately to the carrier.
If the booster is to be installed at a later date make sure it is
stored in a clean, dry location and rotated regularly. Make sure
covers are kept on all openings. If booster is stored outdoors
be sure to protect it from weather and corrosion.
This manual covers the installation, operation and maintenance
of 3200, 4000, 5500 and 7000 Series C-Flange mechanical
vacuum boosters. The boosters are manufactured for either a
vertical ow or a horizontal ow. Most in-eld drive conversions
can be readily accomplished by changing the location of a few
external parts.
Mechanical Vacuum Boosters are built to exacting standards and if properly installed and maintained
will provide many years of reliable service. We urge you to take time to read and follow every step of these
instructions when installing and maintaining your booster. We have tried to make these instructions as
straightforward as possible. We realize getting any new piece of equipment up and running in as little time
as possible is imperative to production.
NOTE
Record the blower model and serial numbers of your machine in the
OPERATING DATA form on the inside back cover of this manual. You will
save time and expense by including this reference identication on any
replacement part orders, or if you require service or application assistance.
