Routine Starting Procedure
▲Caution
After periods of routine shutdown, the following restarting procedure should be followed:
•Start the circulating water pump(s). Increase the flow of circulating water gradually to design water rate to avoid surges or water hammer which could damage the distribution piping.
Circulating cold water over a tower in freezing weather will cause ice to form, which may cause damage to the fill system. Water should be bypassed directly to the cold water basin until the heat load causes its temperature to rise above 70°F (21°C), at which time it may be directed over the tower. Also, towers must not be operated with reduced water rate and/or no heat load during freezing weather. If a bypass is used, do not modulate.
•Start the fan(s). On
