NOTE: Pipe the discharge to a
safe area such as a pit.
When the rise in piping is 30 m (100 ft) or farther from the
PowerTrap, installation of a check valve is recommended
for the prevention of return water hammer.

If water hammer due to steam backflow in the
condensate recovery line is expected, installation
of a check valve vertically and as close as
possible to the recovery line is recommended.

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.
