Before Start-up
Among other sources, outbreaks of Legionnaires’ disease have
reportedly been traced to cooling towers. Maintenance procedures
that prevent amplification and dissemination of Legionella and other
airborne bacteria should be formulated and implemented BEFORE
systems are operated and continued reqularly thereafter to avoid
the risk of sickness or death
CLEANING –New installations should be cleaned and treated with biocides
by a water treatment expert before startup. Remove any dirt and trash which
has accumulated in the cold water basin. Remove any sediment from the cold
water collection basin, sump, and screens. Use a water hose to flush cold
water collection basins.
OPERATE WATER SYSTEM –Start the circulating water pumps. Increase the
flow of circulating water gradually to match design water flow rate. Circulate
water over the cooling tower continuously for several days before starting
the mechanical equipment and placing the cooling tower into continuous
operation.
When starting in cold weather, follow procedures outlined in Cold
Weather Operation.
INSPECTION –It is imperative that all operating assemblies be inspected
before they are placed in operation. The following is a list of components to
be checked before starting the tower:
1–Check driveshaft alignment. Realign if necessary. Refer to the Driveshaft
User Manual .
2–Check tightness of bolts in fan cylinder joints.
3–Check the following bolted joints in the fan and drive assemblies:
a– Fan hub clamp bolts. Refer to the Fan User Manual for correct
torque setting).
b–Fan hub cover bolts (if present).
c–Geareducer
® and motor mounting bolts.
