as a walking surface or working platform. Risk of falling through the surface, resulting in physical injury or
equipment damage.
The upper water distribution channels are filled with water either by the make-up water connection or the recirculation pump.
Water is then distributed over the adiabatic pre-cooler pads via a special hole pattern in the bottom of the upper water
distribution channel. The upper water distribution channels require a specific water flow rate. At least quarterly and upon
seasonal startup, inspect the upper water distribution channels for debris and ensure water distribution holes are not clogged.
The upper water distribution channels can be inspected via the inspection covers that run the length of the unit on the air inlet
faces as shown in Figure 9. Screws securing the inspection cover are for shipping purpose.
