NOTE: 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.

Installation Procedure
Refer to the systems outlined in the “General Description” section on page 5 to select
the correct system and PowerTrap model (GT or GP) for the application. Installation,
inspection, maintenance, repairs, disassembly and adjustment should be done only by
trained maintenance personnel.
(1) Pumped Medium:
!"Fluids that can be discharged through the PowerTrap are limited to steam
condensate, water and non-flammable, non-toxic fluids with specific gravities
0.85 – 1.0. PowerTraps that have been specially constructed for other specific
fluids are not limited by this restriction.
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.
