determined to be workmanship or material defect related we will at our option repair or replace the
part.
Corrective Action - A written report will be provided indicating reason(s) for failure, with suggestions
for corrective action. Subsequent customer failures due to abuse, misuse, misapplication or repeat
offense will not be covered. AMETEK Rotron will then notify you of your options. Any failed unit that is
tampered with by attempting repair or diagnosis will void the warranty, unless authorized by the
factory.
Terms and Conditions - Our warranty covers repairs or replacement of regenerative blowers only,
and will not cover labor for installation, outbound and inbound shipping costs, accessories or other
items not considered integral blower parts. Charges may be incurred on products returned for reasons
other than failures covered by their appropriate warranty. Out-of-warranty product and in warranty
product returned for failures determined to be caused by abuse, misuse, or repeat offense will be
subject to an evaluation charge. Maximum liability will in no case exceed the value of the product
purchased. Damage resulting from mishandling during shipment is not covered by this warranty. It is
the responsibility of the purchaser to file claims with the carrier. Other terms and conditions of sale are
stated on the back of the order acknowledgement.
Installation Instructions for SL, DR, EN, CP, and HiE Series Blowers
1. Bolt It Down - Any blower must be secured against movement prior to starting or testing to
prevent injury or damage. The blower does not vibrate much more than a standard electric motor.
2. Filtration - All blowers should be filtered prior to starting. Care must be taken so that no foreign
material enters the blower. If foreign material does enter the blower, it could cause internal
damage or may exit at extremely high velocity.
Should excessive amounts of material pass through the blower, it is suggested that the cover(s)
and impeller(s) be removed periodically and cleaned to avoid impeller imbalance. Impeller

imbalance greatly speeds bearing wear, thus reducing blower life. Disassembling the blower will
void warranty, so contact the factory for cleaning authorization.
3. Support the Piping - The blower flanges and nozzles are designed as connection points only and
are not designed to be support members.
Caution: Plastic piping should not be used on blowers larger than 1 HP that are operating near
their maximum pressure or suction point. Blower housing and nearby piping
temperatures can exceed 200ºF. Access by personnel to the blower or nearby piping
should be limited, guarded, or marked, to prevent danger of burns.
4. Wiring - Blowers must be wired and protected/fused in accordance with local and national
electrical codes. All blowers must be grounded to prevent electrical shock. Slo-Blo or time delay
fuses should be used to bypass the first second of start-up amperage.
5. Pressure/Suction Maximums - The maximum pressure and/or suction listed on the model label
should not be exceeded. This can be monitored by means of a pressure or suction gage (available
from Rotron), installed in the piping at the blower outlet or inlet. Also, if problems do arise, the
Rotron Field representative will need to know the operating pressure/suction to properly diagnose
the problem.
6. Excess Air - Bleed excess air off. DO NOT throttle to reduce flow. When bleeding off excess air,
the blower draws less power and runs cooler.
Note: Remote Drive (Motorless) Blowers - Properly designed and installed guards should be used
on all belts, pulleys, couplings, etc. Observe maximum remote drive speed allowable. Due to the
range of uses, drive guards are the responsibility of the customer or user. Belts should be
tensioned using belt gauge.
Maintenance Procedure
When properly piped, filtered, and applied, little or no routine maintenance is required. Keep
the filter clean. Also, all standard models in the DR, EN, CP, and HiE series have sealed
bearings that require no maintenance. Bearing should be changed after 15,000 to 20,000
hours, on average. Replacement bearing information is specified on the chart below.

*** Disassembly and repair of new blowers or motors will void the Rotron warranty. Factory should be contacted
prior to any attempt to field repair an in-warranty unit.
Blower Disassembly:
WARNING: Attempting to repair or diagnose a blower may void Rotron’s warranty. It may also
be difficult to successfully disassemble and reassemble the unit.
1) Disconnect the power leads. CAUTION: Be sure the power is disconnected before doing any work
whatsoever on the unit.
2) Remove or separate piping and/or mufflers and filters from the unit.
3) Remove the cover bolts and then the cover. NOTE: Some units are equipped with seals. It is
mandatory that these seals be replaced once the unit has been opened.
4) Remove the impeller bolt and washers and then remove the impeller. NOTE: Never pry on the
edges of the impeller. Use a puller as necessary.
5) Carefully note the number and location of the shims. Remove and set them aside. NOTE: If the
disassembly was for inspection and cleaning the unit may now be reassembled by reversing the
above steps. If motor servicing or replacement and/or impeller replacement is required the same
shims may not be used. It will be necessary to re-shim the impeller according to the procedure
explained under assembly.

6) Remove the housing bolts and remove the motor assembly (arbor/.housing on remote drive
models).
7) Arbor disassembly (Applicable on remote drive models only):
a) Slide the bearing retraining sleeve off the shaft at the blower end.
b) Remove the four (4) screws and the bearing retaining plate from the blower end.
c) Lift the shaft assembly far enough out of the arbor to allow removal of the blower end snap
ring.
d) Remove the shaft assembly from the arbor.
e) If necessary, remove the shaft dust seal from the pulley end of the arbor.
Muffler Material Replacement:
1) Remove the manifold cover bolts and them manifold cover.
2) The muffler material can now be removed and replaced if necessary. On blowers with fiberglass
acoustical wrap the tubular retaining screens with the fiberglass matting before sliding the muffler
pads over the screens.
3) Reassemble by reversing the procedure.
NOTE: On DR068 models with tubular mufflers it is necessary to remove the cover and
impeller accessing the muffler material from the housing cavity.
Blower Reassembly:
1) Place the assembled motor (assembled arbor assembly for remote drive models) against the rear
of the housing and fasten with the bolts and washer.
2) To ensure the impeller is centered within the housing cavity re-shim the impeller according to the
procedure outlined below.
3) If blower had a seal replace the seal with a new one.
4) Place the impeller onto the shaft making sure the shaft key is in place and fasten with the bolt,
washer and spacer as applicable. Torque the impeller bolt per the table below. Once fastened
carefully rotate the impeller to be sure it turns freely.
5) Replace the cover and fasten with bolts.
6) Reconnect the power leads to the motor per the motor nameplate.
Bolt Size Torque
Pound-Force-Foot
1/4-20 6.25 +/- 0.25
5/16-18 11.5 +/- 0.25
3/8-16 20.0 +/- 0.5
½-13 49.0 +/- 1
5/8 –11 90.0 +/- 2

Impeller Shimming Procedure:
WARNING: This unit may be difficult to shim. Extreme care may be exercised.
Tools Needed: Machinist’s Parallel Bar
Vernier Caliper with depth measuring capability
Feeler gauges or depth gauge
Measure the Following:
Distance from the flange face to the housing (A)
Distance from the flange face to the motor shaft shoulder (B)
Impeller Thickness (C)
Measurements (A) and (B) are made by laying the parallel bar across the housing flange face and
measuring to the proper points. Each measurement should be made at three points, and the average
of the readings should be used.
Shim Thickness = B – (A+C)/2
After the impeller installation (step #4 above) the impeller/cover clearance can be checked with feeler
gauges, laying the parallel bar across the housing flange face. This clearance should nominally be
(A-C)/2.
