7.3.5 Water Distribution
Maintaining even water distribution to the pads is the most important way of extending pad life. If an area of pad
does not receive enough water, cooling efficiency will be degraded. The
Spray Bar Adjustment Valve
should be
increased until the pads are fully wet, but not to the extent that a mist is blown out of the fan.
Dry spots or streaks can also be caused by clogged holes in the spray bar. Investigate by removing the pad cover
plates and running a pipe cleaner, or small dowel into the holes in the spray bar to clear any clogged holes. The
spray bar end caps may be removed for easier cleaning. Ensure the holes in the spray bar point upward during
operation.
7.4 Flushing the Reservoir
The pads and the complete water system should be flushed out at least once a week and the reservoir wiped clean.
1.
Turn off the pump, fan, and water source, unplug the unit and drain the reservoir. The reservoir can be drained
using the Drain Outlet.
2.
Wipe out the reservoir.
NOTE
: Do not allow the pump to run without water in the reservoir. Without water, the pump may be damaged.
3.
Restore the water source and fill the reservoir.
4.
Run the pump for at least 15 minutes.
5.
Pump the reservoir out again and refill with fresh water.
6.
Start the pump and fan.
