SPX Cooling Technologies MARLEY CLASS F400 - Manual (Page 7)

Always shut off electrical power to the tower fan motor prior to
performing any inspections that may involve physical contact with
the mechanical or electrical equipment in or on the tower. Lock out
and tag out any electrical switches to prevent others from turning
the power back on. Service personnel must wear proper personal
protective clothing and equipment.
Well-maintained equipment gives the best operating results and the least
maintenance cost. SPX recommends setting up a regular inspection schedule
to insure effective, safe operation of the cooling tower. Use the schedule on
page 19 to obtain continuously good performance with the least tower main-
tenance. See Cooling Tower Inspection Check List in this manual. Keep a
continuous lubrication and maintenance record for each cooling tower.
HOT WATER DISTRIBUTION SYSTEM –Keep the circulating water and
distribution system (piping and nozzles) clean and free of dirt, algae, and scale.
Algae and scale may clog nozzles, eliminators, fill, and piping, and may collect
on the equipment served thus reducing its performance.
An access hatch in the fan deck with ladder to an intermediate platform pro-
vides means for inspection of the plenum area above the eliminators. Removal
of an access hatch at the plenum level allows access to the spray chamber
for inspection and maintenance of the nozzles and top of fill. Provide surface
protection before walking on the fill.
DRIFT ELIMINATORS –Eliminators should be kept clean.
Do not walk or step on the eliminators without planking and safety
harness.
COLD WATER COLLECTION BASIN –Inspect collection basin occasionally
for leaks and repair if necessary. Keep cold water outlets clean and free of
debris. Makeup and circulating water controls must operate freely and maintain
the desired water quantity in the system.
DRIVE SHAFT –Check drive shaft alignment and condition of couplings every
six months. Refer to the Driveshaft User Manual for correcting misalignment,
balancing, or replacing parts.
