Nozzle spray distribution type
FAN SHAFT
The exposed areas of the fan shaft are coated with a soft seal for added corrosion protection. It is recommended
that the coating be inspected for continuity quarterly or at least every 6 months. Any signs of surface corrosion
must be treated. This involves:
1. Removal of the protective coating with a suitable cleaning medium.
2. The removal of any surface corrosion with emery cloth.
3. The re-coating of the shaft with soft seal.
FAN MOTOR
During operation it is required to clean the outside surface of the motor at least every 6 months (or more often
depending on site conditions) to ensure proper motor cooling. Do not wash down the motor unless it is IP 66 rated.
On a quarterly or six monthly basis check:
• Electric connections
• Motor protection devices
• Check amp draw
• Motor bearings for noise/overheating
• Motor holding bolts
• External surface of motor for corrosion
