Installation Procedure
Installation, inspection, maintenance, repairs, disassembly, adjustment and valve
opening/closing should be carried out only by trained maintenance personnel.
(1) Pumped Medium:
Fluids that can be discharged through the PowerTrap are limited to steam
condensate. PowerTraps that have been specially constructed for other specific
fluids are not limited by this restriction.
(2) Motive Medium Supply Pipe [Sm
1
] and Motive Medium Supply Tube [Sm
2
]:
The motive medium supply pipe [Sm
1
] and valve on motive medium supply pipe
[Vm] diameter should be at least 15 mm (
1
/
2
”). If copper or stainless steel tubes are
used for the connection from the motive medium supply pipe [Sm
1
] to the
PowerTrap, make sure that the tube
’s inner diameter is at least 8 mm (
5
/
16
”) but no
more than 3 m (10
’) in length.
The inner diameter of the valve and tube fittings connecting to the PowerTrap
should also be at least 8 mm (
5
/
16
”).
Install a strainer [Km] (at least 15 mm (
1
/
2
in) and at least 40-mesh) on the
PowerTrap motive medium supply pipe [Sm
1
] as close to the PowerTrap as
possible and install a union joint for maintenance, while allowing sufficient space
for maintenance of the strainer. Strainers should be angled in the 3 or 9 o’clock
positions for horizontal installations.
Only use steam as the motive medium.
The maximum motive medium supply pressure is 0.5 MPaG (75 psig, 5 barg).
Install a drip leg on the motive medium supply pipe [Sm
1
], and a steam trap [ST] on
the drip leg.
Proper discharge capacity may not be achieved if condensate accumulates in the
motive medium supply pipe [Sm
1
] or tube [Sm
2
]. In addition, rust and scale cause
steam leakage, which results in the PowerTrap
becoming inoperable.
Make sure to use steel pipe for the motive medium supply tube [Sm2].
