TECO AEHB User Manual

TECO Instruction Manual
Squirrel Cage Induction Motors
Whilst Motors are installed awaiting commissioning they must be adequately
protected against the elements, all external components in particular the shaft
extension and external labyrinth seals at the drive end must be fully covered
to avoid water ingress entering the motor body whilst stationery.
Please ensure that both the non drive end and drive end antifriction bearings
are fully purged with sufficient grease at first start up/commissioning
with the recommended grade and quantity of grease.
