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 18 and
19 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.
11– Check dry damper linkage to be sure linkage is properly functioning.
Actuate dry dampers to make sure they open and close.
12– Check dry duct vent doors to see that linkage is properly functioning. In cold weather
if possible inspect doors for snow and ice that may freeze doors shut. Tower may
need to operate with heat load to melt snow and ice prior to operating vent doors.
Actuate dry duct vent doors to make sure they open and close.
Starting Procedure
WATER SYSTEM
–Fill the cold water collection basin and circulating water system until
the operating water level is reached. See
Operation
. Prime and start the circulating
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 Op-
eration.
FAN START
–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 the Fan User Manual for instructions.
Pitch fans to pull correct contract horsepower when circulating design water rate at
design hot water temperature.
