· Use a rust preventave oil with a ash point over 400°F
· Dispose of used rust preventave oil according to local regulaons
Installation
Rotation and Airow
Diesel Engine Precautions
· DO NOT OPERATE BLOWER WITH A DIESEL ENGINE RUNNING AT
LOW RPM’S AS TORQUE PULSES CAN CAUSE ROTOR LOBE CONTACT
AND DAMAGE TO THE BLOWER.
When directly driving the blower with Diesel engine, bring the engine up to oper-
ang RPM and then engage the blower via the clutch. Be sure to start the blower
under no load condions.
Use cauon when using a Diesel engine that is signicantly oversized for the
operang point of the blower. Doing so can result in an ineral mismatch, excess
torsional vibraons at low RPM’s and blower lobe contact.
Direct Coupler Installation and Alignment
Slide the couplers onto the blower sha and prime mover sha using appropriate
tools.
