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 Gardner Denver 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 possible) 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 protected against rust and corrosion.
4. Provide adequate protection to avoid accidental mechanical damage.
5. In high humidity or corrosive environments, additional measures may be required to prevent
rusting 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 operating level with clean,
fresh lubricant.
7. Rotate the blower shaft (10 to 25 turns) monthly during storage. Inspect the blower shaft
(near the shaft seal area) monthly and spray with rust inhibitor if needed.
8. For long term storage (over six (6) months), contact Gardner Denver Customer Service for
recommendations.

HF-7-602 Page 10
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 HeliFlow blowers 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 portion 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 severe injury in case of personal contact. Keep hands away
from blower inlet and discharge ports.

HF-7-602 Page 11
SECTION 2
INSTALLATION
LOCATION
If possible, install the blower in a well lit, clean, dry place with plenty of room for inspection and
maintenance.
FOUNDATIONS
For permanent installations we recommend concrete foundations be provided, and the equipment should
be grouted to the concrete. It is necessary that a suitable base be used, such as a steel combination
base under blower and motor, or a separate sole plate under each. Before grouting, equipment must be
leveled, free of all strains, and anchored so no movement will occur during setting of grout. After grout
has completely hardened, a recheck is necessary to compensate for shrinkage, etc. If required, add
shims under blower feet after final tightening of foundation anchor bolts to remove strain from the blower
housing. Where jack screws or wedges are used during grouting, they must be backed off or removed
before final tightening of anchor bolts.
Where a concrete foundation is not feasible, care must be taken to insure that equipment is firmly
anchored to adequate structural members.
MOUNTING CONFIGURATIONS
The blower flex-mounting design enables horizontal and vertical mounting configurations with top or
bottom hand, right or left hand shaft positioning. The units are discharge timed allowing rotation in only
one direction (refer to FIGURE 2-1 page 12, FIGURE 2-2 page 13. If converting a blower from vertical
bottom hand drive to vertical top hand drive or vice versa, the oil slinger on each end must be moved to
the lower rotor.

NOTICE
When changing mounting configuration, it will be necessary to reposition oil level gauge (H),
and drain plug (A). Refer to FIGURE 3-1, page 17, for correct location.
For Vertical Models, the oil slinger must be on the lower rotor or blower failure is immediate.
DRIVE INSTALLATION
When selecting a V-belt drive, check to be sure the shaft overhung load limitation is not exceeded. Refer
to FIGURE 2-3, page 15, for overhung load calculations and limitations.
Belt drives must be carefully aligned. Motor and blower pulleys must be parallel to each other and in the
same plane within 1/32 inch. Belt tension should be carefully adjusted to the belt manufacturer’s
recommendation using a belt tension gauge. Check tension frequently during the first day of operation.
Over tightening belts leads to heavy bearing loads and premature failure.
On the direct connected units, alignment and lubrication of couplings to specifications of the coupling
manufacturer is very important. When mounted drives are supplied from the factory, proper alignment
has been established before shipment. However, during shipping, handling and installation, it is likely
that the alignment has been disturbed and final adjustment must be made before startup.
Exceeding overhung load limitations leads to unwarrantable premature bearing failure and shaft
breakage.
The location of the sheave on the blower shaft greatly affects the stress in the shaft. The optimum blower
sheave positioning is as close as possible to the blower drive cover, not to exceed dimension “C”in Drive
Shaft Illustration, FIGURE 2-3, page 15.
The calculated shaft moment must not exceed the maximum allowable moment listed in Maximum
Allowable Moment Chart, FIGURE 2-3, page 15. If the calculated shaft moment exceeds the maximum
allowable moment:
•Increase Sheave Diameters to Reduce Belt Pull
•Use Jackshaft Drive
•Use Direct Coupled or Gearbox Drive
To calculate shaft moment for a given V-Belt Drive Arrangement:
1. Use the formula for Calculation of Belt Pull, FIGURE 2-3, page 15, to calculate belt pull.
Refer to Arc of Contact Factor Chart, FIGURE 2-3, page 15.
2. Insert the calculated belt pull into the formula for Calculation of Shaft Moment,
FIGURE 2-3, page 15 to arrive at the calculated shaft moment.

PIPING
Inlet and discharge connections on all blowers are large enough to handle maximum volume with
minimum friction loss. Reducing the pipe diameter on either inlet or discharge will only create additional
line loss and increase the overall pressure differential.
Excessive weight of piping and fittings will cause internal misalignment and premature wear. Never allow
the blower to carry the weight of the pipe. If possible, a spool or sleeve-type expansion joint should be
installed between the unit and the piping. Where a flexible connection is not practical, the weight of the
rigid connection must be separately supported. All system piping must be cleaned internally before
connecting to the blower.
Gardner Denver blowers are shipped dry from the factory. Do not attempt to operate the blower
before following proper lubrication instructions. Permanent damage to the gears, bearings and
seals will occur.

HF-7-602 Page 17
SECTION 3
MAINTENANCE
FIGURE 3-1 - LUBRICATION
GENERAL
Blower efficiency and life depend on the quality of maintenance the blower receives. Maintenance must
be done regularly and with care. Clean work space, tools, solvents and wiping rags are necessary to
avoid transferring dirt into the unit. Scheduling regular maintenance of the blower will insure long trouble-
free service.
LUBRICATION
Gears and bearings are splash lubricated by an oil slinger in each sump. Check the oil level in both
sumps daily. Do not operate the blower if the oil level is not in the middle of the sight gauge for each
sump when the blower is not running. An overfill or excess of oil can cause oil leaks. DO NOT
OVERFILL OIL.
FILLING PROCEDURE
Refer to FIGURE 3-1. While the blower is not running remove the plug (B) from each sump. Add oil to
each sump until it reaches the middle of each oil level sight gauge (H). After adding oil wait for oil level
to stabilize. Add or remove oil to maintain oil level at middle of oil level sight gauge. Secure the plug (B)
in each end.
LUBRICATION SERVICE
Add fresh oil as required to maintain proper level. The oil change period is governed by operating
conditions such as load, temperature, dirt, humidity, fumes and the quality of the oil used. The oil drain
plug is located at (A). With AEON PD Series synthetic blower lubricant, perform the above oil-change
maintenance after 4500 to 7500 hours.
Do not overfill oil as this will tend to cause excessive heating of the gears and may damage the
unit. An overfill of oil can cause oil leaks.
