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. See Geareducer 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. See Fan User Manual.
6–Check motor insulation with a “Megger”. See 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 vibra-
tion 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.
10–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. See Operation Section, below. Prime and start the circulating water pumps. Increase the flow of circulating water gradually to design water flow rate to avoid water ham- mer which could damage the distribution piping system.
Clean the sump screens several times during the first weeks of op- eration. After this, clean sump screens weekly.
When starting in cold weather, follow procedures outlined in Cold Weather Operation.
STARTING FAN–Start the fan. After 30 minutes of operating time to permit Geareducer oil to come up to operating temperature, check motor load with watt meter, or take operating volt and ampere readings and calculate motor hp. Refer to Marley Fan User Manual for instructions. Pitch fans to pull correct contract horsepower when circulating design water rate at design hot water temperature.
Operation
Entering water temperature in excess of 125°F may result in fill de- formation.
