ADIABATIC PRE-COOLER WATER FLOW
A minimum water flow must be distributed over the adiabatic pre-cooler as per minimum water flow rates. (See
table below "Minimum recommended adiabatic pre-cooler water flow rates").
The water flow will depend on the supply water pressure, and can be set with the 2 concentric hex screws on the
water flow valve on the flow meter. First open the plastic cover plate of the water flow adjustment screw.
