WATER DISTRIBUTION OF PRE-COOLERS EQUIPPED WITH RECIRCULATION
PUMP
The strainer at the pump is sized to keep debris out of the water distribution gutter. However, some dirt could
accumulate overtime. As a result the water distribution gutter at the top should be cleaned twice a year as a
preventive measure.
The recommended procedure for cleaning of the water distribution header is:
1. Open the hinged pre-cooling media cover (the 1st time, remove the tappers which secure the cover during
transport first)
2. Use a clean piece of cloth to remove any dirt or debris from the gutter.
1. Distribution gutter
3. After the gutter is cleaned, put everything back in place in the reverse order and close the cover.
STRAINER AND PUMP OF PRE-COOLERS EQUIPPED WITH RECIRCULATION PUMP
Both the pump and strainer can be cleaned during adiabatic operation. Before performing any maintenance on the
pumps, cut the power to the pumps in the electrical panel first. Adiabatic operation can be ensured through the
controller’s maintenance menu.
1. Loosen the knobs and remove the inspection panel (in case of two pumps, the unit is equipped with two
panels).
