Maintenance

 

 

Clean and disinfect cooling tower with biocides. Systems with biofouling,

 

 

high general bacterial counts, or positive cultures of legionella may require

 

 

additional cleaning. Refer to “Fluid Cooler Cleaning” section—page 21.

 

 

Consult your water treatment expert as to prudent biological evaluation

 

 

testing.

 

 

 

Note

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

 

 

oil 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.

 

 

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

 

 

opposite end bearings and remove hardened grease, using clean
