Protection Against Corrosion
Geareducer® units ship from the factory with a protective coating of
epoxy enamel paint on all unmachined parts and with rust-proofing
oil and grease on machined surfaces. Machined surface coatings
normally protect the Geareducer against atmospheric corrosion
during storage periods for up to six months. However, if oil is
added to the Geareducer, the new oil will dissolve the rust-proofing
grease and require that the Geareducer be run once a week to
keep a protective coating of oil on all interior machined surfaces.
Check Geareducer exterior yearly and touch up with epoxy paint if
required. If your Geareducer is equipped with an oil gauge and drain
line, coat any exposed threads at pipe joints to prevent corrosion.
Alignment
In order to assure long service life, the Geareducer and motor must
be level, and the drive shaft or coupling must be properly aligned.
Refer to the alignment instructions in the Driveshaft or Coupling
Manual shipped with the cooling tower. Copies are also available
from your local Marley sales representative.
Initial Operation
Check to be sure that the Geareducer is filled with oil and that
there are no visible oil leaks. If equipped with an external dipstick/
oil level gauge, be sure the oil full mark corresponds with the full
level at the Geareducer.
Note
—If this tower is equipped with a two-speed motor, allow a
time delay of at least 20 seconds when switching from high speed
to low speed. Allow a time delay of at least two minutes when
changing direction of fan rotation. Failure to provide these delays
may significantly reduce equipment service life.
