INTRODUCTION
YOUR KEY TO TROUBLE FREE SERVICE
Thank you for investing in Sutorbilt quality. The
Sutorbilt reputation for rugged dependability has been
earned by over 50 years of service in demanding,
industrial operations where downtime cannot be
tolerated and efficient blower performance is expected.
Your Sutorbilt blower is a precision engineered blower
that has been carefully manufactured and thoroughly
tested at the state-of-the-art Gardner Denver Blower
Factory in Sedalia, Missouri.
As with other precision machinery, there are several
relatively simple installation, operation and mainte-
nance procedures that you must observe to assure
optimum blower performance. There is no guesswork
in the manufacture of your highly advanced Sutorbilt
blower and there must be none in preparing the blower
to get the job done in the field.
The purpose of this manual is to help you properly
install, operate and maintain your Sutorbilt blower. It is
essential that you review all sections of this manual in
preparation for installing your blower. Follow the
instructions carefully and you will be rewarded with
trouble--free Sutorbilt service ...yearinandyearout.

SECTION 1
EQUIPMENT CHECK
Before uncrating, check the packing slip carefully to be
sure all the parts have been received. All accessories
are listed as separate items on the packing slip, and
small important accessories such as relief valves can
be overlooked or lost. After every item on the packing
slip has been checked off, uncrate carefully.
Register a claim with the carrier for
lost or damaged equipment.
Customers are cautioned to provide
adequate protection, warning and
safety equipment necessary to protect
personnel against hazards involved in
installation and operation of this
equipment in the system or facility.
STORAGE
Your Sutorbilt Blower was packaged at the factory with
adequate protection to permit normal storage for up to
six (6) months.
If the unit is to be stored under adverse conditions or
for extended periods of time, the following additional
measures should be taken to prevent damage.
1. Store the blower in a clean, dry, heated (if pos-
sible) area.
2. Make certain inlet and discharge air ports are
tightly covered to prevent foreign material from
entering the air box.
3. All exposed, non--painted surfaces should be pro-
tected against rust and corrosion.
4. Provide adequate protection to avoid accidental
mechanical damage.
5. In high humidity or corrosive environments, addi-
tional measures may be required to prevent rust-
ing of the blower internal surfaces.
6. To prevent rusting of gears, bearings, etc., the oil
reservoirs may be filled with normal operating oil.
Before running the blower, drain the
oil and replace to the proper operat-
ing level with clean, fresh lubricant.
7. Rotate the blower shaft (10 to 25 turns) weekly
during storage. Inspect the blower shaft (near the
shaft seal area) monthly and spray with rust inhibi-
tor if needed.
8. For long term storage (over six (6) months),
contact Sutorbilt Customer Service for recom-
mendations.
REMOVING PROTECTIVE MATERIALS
The shaft extension is protected with rust inhibitor
which can be removed with any standard solvent.
Follow the safety directions of the
solvent manufacturer.
Blower inlet and outlet are temporarily capped to keep
out dirt and other contaminants during shipment.
These covers must be removed before start--up.
The internal surfaces of all Sutorbilt units are mist
sprayed with a rust preventative to protect the machine
during shipment. Remove this film upon initial startup,
using any commercial safety solvent. Position the
blower so that the inlet and discharge connections are
in the vertical position (vertical airflow). On vertically
mounted units, it will be necessary to lay the unit on its
side supporting the ends of the unit so as not to restrict
the port on the bottom side. Place a shallow pan on the
under side of the unit. With the blower disconnected
from power, spray the solvent in the top port, rotating
the impellers by spinning the shaft manually. Continue
this procedure until the unit is visibly clean.
Rotating components will cause se-
vere injury in case of personal contact.
Keep hands and loose clothing away
from blower inlet and discharge ports.
