Caution

Maintenance

bright metal can be exposed by cleaning, consider that the galvanizing has remained effective. Unless there is 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.

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: If equipped, lubricate fan shaft bearings at close of each operating season—see page 26.

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. See Page 28 for fluid coolers with motor located outside the plenum option.

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 92-1475available at spxcooling.com.

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
