c) If abnormal phenomena are found in the fan system, it should be immediately stopped for
inspection and troubleshooting. The blades should be repaired or replaced based on the actual
erosion and wear situation to ensure that the cooling tower is in good operating condition;
d) During the use of the cooling tower, if excessive water loss is found, manual replenishment
devices should be used in a timely manner to replenish water. In addition, check whether the
water collector is damaged and whether the water collection tank is leaking;
e) It is required to clean the inside and outside of the tower once a year to prevent the accumulation
of dirt from affecting the smooth flow of water.;
f) After the cooling tower is shut down, the residual water in the water collection tank and pipelines
must be emptied. If the shutdown time is long, the entire tower should be inspected to ensure
safe and normal operation next time;
g) Flammable materials such as fillers and water collectors are strictly prohibited from coming into
contact with open flames during use or maintenance;
h) Under the freezing point temperature in winter, the system will switch to dry cooling mode. At
this time, it is necessary to drain the residual water in the water collection tank and pipelines to
prevent equipment damage caused by icing;
i) The filters inside the water collection tank need to be cleaned once a month to prevent damage
to the spray pump caused by dirt and blockage;
j) PVC fillers should be washed regularly and should not be operated under conditions where the
cooling water temperature is higher than 50℃.
