4–Check Geareducer oil for sludge or water by draining off and testing a
sample as outlined in the Geareducer User 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. Refer to theGeareducer User Manual
for oil filling procedure and list of recommended lubricants.
5–Rotate fan by hand to be sure of free rotation and ample tip clearance.
Refer to theFan User Manual.
6–Check motor insulation with a “Megger”. Refer to the Maintenance Section
of Marley Electric Motor User Manual.
7–Lubricate the motor according to motor manufacturer’s instructions.
8–Test run each fan separately for a short time. Check for excessive vibration
or unusual noise. If either is present, see Troubleshooting Guide on pages
14 and 15 of this manual. Fan must rotate clockwise when viewed from
above. Recheck Geareducer oil level.
9–Check functioning of make-up water supply. Make sure the blowdown will
carry the proper amount of water.
Starting Procedure
WATER SYSTEM –Fill the cold water collection basin and circulating water
system until the operating water level is reached. Prime and start the circulat-
ing water pumps. Increase the flow of circulating water gradually to design
water flow rate to avoid water hammer which could damage the distribution
piping system.
Clean the sump screens several times during the first weeks of
operation. After this, clean sump screens weekly.
When starting in cold weather, follow procedures outlined in Cold
Weather Operation.
STARTING FAN –Operate the fan for 30 minutes to permit the Geareducer
oil to come up to operating temperature and check the motor load with watt
meter, or take operating volt and ampere readings and calculate motor hp.
Refer to the Fan User Manual for instructions. Pitch fans if required to pull
correct contract horsepower when circulating design water rate at design
hot water temperature.
