Spray Water Basin
Multi-module units have a continuous spray water basin with a single mechanical
make-up valve, solenoid make-up valve, high/low level switches, overflow, and drain
valve. Each module includes a spray pump.
Mechanical Make-up Valve
A float-operated mechanical make-up valve assembly is furnished on the unit. It consists
of a corrosion resistant make-up valve connected to a float arm assembly that is actuated
by a plastic float. The float consists of a primary pilot actuator that actuates the main
diaphragm to open the float valve. The float that controls the spray water basin operating
water level can be adjusted by loosening the thumbscrew and extending or shortening the
float arm.
