Evaporative Cooling with Auto Drain and Fill
continued
1. Install the Water Supply Line
Supply line opening requirements vary by unit size and arrangement and are field supplied. Connect the water supply line to the float valve through the supply line opening in the evaporative cooling unit. Install the 1/2 in. normally closed solenoid (Valve A) in the supply line. Install the 1/4 in. normally open solenoid (Valve
B)between the supply line and the drain line. Refer to Auto Drain & Fill Evaporative Piping drawing on previous page.
2. Install the Drain Line
Connect an unobstructed drain line to the sump drain overflow connection. Install the 3/4 in. normally open solenoid (Valve C)
between the sump drain connection
and the drain line. A trap should be
used to prevent sewer gas from
being drawn into the unit.
3. Check/Adjust Water Level
Check the water level in the sump tank. The water level should be above the pump intake and below the overflow. Adjust the float as needed to achieve the proper water level.
