Fluid cooler 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: Lubricate fan shaft bearings at close of each oper-
ating season—see page 22.
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(s) should be operated for three hours at least once a month.
This serves to dry out windings and re-lubricate bearing surfaces. Refer
to the Marley
“Electric Motor User Manual” Manual 92-1475 available
at spxcooling.com.
At start of new operating season, make sure bearings are adequately
lubricated before returning motor to service.
