Maintenance
Tower framework: Check structural bolted connections and tighten as
required.
Fans: Check fan assembly bolting and tighten as required. Use torque
values prescribed in the Fan User Manual.
Fans shaft bearings: If equipped, lubricate fan shaft bearings at close of
each operating season—see page 21.
Electric motors: 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.
