NOTE: Pipe the discharge to a
safe area such as a pit.
**If the pressure at the PowerTrap inlet exceeds the pressure at the PowerTrap outlet, make sure to install
a steam trap at the PowerTrap outlet. (Steam will blow if no steam trap is installed.)
Make sure the pipe between the PowerTrap and the steam trap is as short and thick as possible.
There should be no rise in piping between the PowerTrap and the steam trap.
Select the steam trap based on the pump discharge capacity of the PowerTrap. Consult TLV for details.
NOTE: This sketch is for explanation purposes only and is not intended as an installation design.
In closed system applications, the motive medium must be compatible with the liquid
being pumped. If a non-condensable gas such as air or nitrogen is used as the motive
medium, please consult TLV for assistance.

When the rise in piping is 30 m (100 ft) or farther from the
PowerTrap, installation of check valve is recommended
for the prevention of return water hammer.
