Select a location over or nearest to the heaviest building structural members. These members 
should be outside load-bearing walls, building columns, or roof joists. You may need to 
spread the load over several structural members to provide support without over-stressing any 
one member. See Figure 1 on page 11 for structural steel support requirements. You are 
responsible for contacting a structural engineer to verify support requirements. 

Choose a site with easy access to simplify routine maintenance. This consideration is 
especially important when a tower is located near a roof edge. 

Avoid locations where wind currents can re-circulate tower discharge air. 

Stay clear of roof discharge points. Avoid stacks, exhaust fans, dust collector discharges, or 
any process that can contaminate air circulating through the tower. 

Elevate the tower so that positive pressure is on pump suction and to allow maintenance 
access to the underside of the tower cell.   

Outside Installation with the Pump Tank Reservoir Inside. Water exits the tower and 
drains to a pump tank reservoir inside the building below. The tower outlet must be at least 
three feet (approximately 1 meter) above the top of the pump tank. The outside tower basin 
must drain completely when shut down to avoid winter freeze up. 

Outside Installation Using the Tower Basin as a Reservoir. Process pump suction piping 
is directly connected to the bottom outlet on the tower. Install the optional outlet basket filter 
and automatic float assembly. Contact the Sales department for this accessory kit. 

Note:  A dimension of 60”is required between the tower air inlet and the wall of a  

building.  See above caution for required distance between towers.
