HOT WATER BASINS
The system water enters the cooling tower through the hot water basin(s). (See figure below). At design flow, the
operating level should not be less than 50 mm or greater than 125 mm deep. Quarterly, or more often as required,
remove any dirt or debris which may clog the nozzles. Seasonally clean and flush the hot water basin with fresh
water.

OPERATING LEVEL AND MAKE-UP
Before initial start up the straps, that prevent the float ball from moving during transport, as well as the protective
bag around this ball, need to be removed.
Fixation and wrapping of float ball
As the water circulating through the unit is cooled, it collects in the cold water basin and passes through the
strainers into the system.
The operating water level is controlled by the make-up valve and should be maintained at the operating water level
shown in the table below.
