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 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
–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 cor-
rect 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
deformation.
