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 Service 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 as-
semblies:
– Fan hub clamp bolts. See Marley Fan Service 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.
