3-6 Setting Up the Water Balancing Valve
Install the plug provided in the unused water inlet on the side of the tower. Tighten and check for leaks.
To prevent damage to the tower fill material, use the water throttling valve and pressure gauge to regulate the water pressure to the tower spray nozzle(s). The recommended throttling valve is a

3-7 Initial Start-up
Check for proper rotation on all fan and pump motors. Refer to the arrows atop the tower and on pump housings.
Fill the system with water and adjust the float valve if you are using a float. Maintain a water level in the tower basin approximately one inch (25 mm) below the overflow opening.
The tower basin acts as a sump to maintain water level. Towers using inside tanks do not carry water in the basin.
