Maintenance

additional cleaning. Refer to “Fluid Cooler Cleaning” section—page 21. Consult your water treatment expert as to prudent biological evaluation testing.

Geareducer models used on MH Fluid Coolers are designed for 5-year

Noteoil change intervals. To maintain five-year change intervals, use only oil designed specifically for these Geareducers. If, after five years, turbine-type mineral oil is used, the oil must be changed semiannu- ally. Refer to the Geareducer User Manual for oil recommendations and further instructions.

Annually: Relubricate motor(s) according to the manufacturer’s instruc- tions. See instructions on the next page for towers with the motor located outside the plenum option.

Check to see that all bolts are tight in the fan and mechanical equipment region, including the fan cylinder and fan guard. Refer to Component User Manuals for torque values.

Inspect the fluid cooler thoroughly, making maximum use of instructions given in the separate user manuals. Check structural bolted connections and tighten as required. Make preventive maintenance repairs as neces- sary.

Check to see that all bolts are tight in the fan and mechanical equipment region, including the fan cylinder and fan guard. Refer to Component User Manuals for torque values.

Every 5 Years: If equipped, change Geareducer oil. Refer to the Geareducer User Manual for instructions.

Motor Relubrication Instructions

Motor located outside plenum option. Double-flow models MHF706 and

MHF707 only.

Open and lock out disconnect switch to make certain motor cannot be started.

1. Remove guard as shown in Figure 4. Opposite end motor bearing is accessible from outside the tower.

2. Remove grease fill and relief plugs at both shaft extension end and op-

posite end bearings and remove hardened grease, using clean wire.
