Before Start-up
Safety
Temporary safety barricades should be placed around any exposed
openings in the operating (or nonoperating) tower, safety harnesses
should be worn by personnel where appropriate, and other safety
precautions should be taken in compliance with OSHA regulations
and standards.
Cleaning
Clean any nozzles that are clogged. Remove any sediment from the cold water
basin, sump and screens. Use a water hose to flush cold water basins. If you
are restarting or recommissioning a previously used tower, see Warning
note on page 17.
Inspection
It is imperative that all operating assemblies be inspected before they are
placed in operation. The following is a list of components to be checked
before starting the tower:
• Check drive shaft alignment. Realign if necessary. See Marley Drive Shaft
User Manual.
• Check tightness of bolts that attach mechanical equipment support to
the tower structure. Check tightness of bolts in fan cylinder joints and fan
cylinder anchorage.
• Check concrete structural surfaces for spalling and cracks. Repair as
necessary.
• Check tightness of the following bolted joints in the fan and drive
assemblies:
– Fan hub clamp bolts. See Marley Fan User Manual for correct torque
setting.
– Fan hub cover bolts, where applicable.
– Geareducer and motor mounting bolts.
– Drive shaft coupling and guard bolts.
• Check Geareducer oil for sludge or water by draining off and testing a sample
as outlined in the Marley Geareducer Service Manual. Check Geareducer oil
level at “oil level” mark on the side of the case. Add oil as required. The oil
level placard must be adjusted so that its “full” mark is at the same elevation
as the “full” mark on the side of the Geareducer case. Check oil lines to be
sure there are no leaks and all joints are tight. See Geareducer User Manual
for oil filling procedure and list of recommended lubricants.
