evidence of a generalized failure of the galvanizing, localized touch-up
should be all that is required.
To the extent that the galvanizing (zinc coating) still exists, paint will
not adhere to it readily. Contact the manufacturer of the coating you
intend to use for instructions.
Tower framework: Check casing and structural bolted connections and
tighten as required.
Fan: Check fan assembly bolting and tighten as required. Use torque
values prescribed in the Fan User Manual.
Fan shaft bearings: Lubricate fan shaft bearings at close of each operat-
ing season—see page 32.
Clean and lubricate motor at close of each operating season (refer to
motor manufacturer’s recommendations.) Check motor anchor bolts and
tighten as required.
Do not start motor before determining that there will be no interfer-
ence with free rotation of the fan drive.
The motor should be operated for three hours at least once a month. This
serves to dry out windings and re-lubricate bearing surfaces (refer to Marley
“Electric Motor User Manual” Manual 92-1475 ).
At start of new operating season, make sure bearings are adequately
lubricated before returning motor to service.
Prolonged Shutdown
If shutdown period is longer than seasonal, contact your Marley sales
representative for additional information.
