BAC DCV Series Rigging And Installation Instructions page 20

The surplus of water distributed over the Adiabatic Pre-Cooling media during adiabatic operation is collected into a
gutter and drained to the sewer via one or two different drains per pre-cooler side.
8-fan, 10-fan and 12-fan coolers are equipped with 4 separately shipped Adiabatic Pre-Cooling sections, 2 per side.
Each Adiabatic pre-cooler section is equipped with a separate bottom drain guaranteeing full emptying and drying
of the gutter system after each adiabatic cycle.
Refer to the Table below for the number of Adiabatic Pre-Cooler sections and number of drains per model.

DCV-S9126-*
Each pre-cooler section has a sloping pan, assuring complete water drainage and discharge of any floating solids
to the sewer. Larger debris will however accumulate and settle in the gutter system and may be too large to drain
via the bottom drain and finally may block the bottom drain.

It is therefore necessary to regularly clean the Adiabatic Gutter system to remove all solids. Access for cleaning is
given to the inside of the gutter system after removal of the Pre-Cooling Media.
