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 and water. PowerTraps that have been specially constructed for other
specific fluids are not limited by this restriction.
(2) Connecting the piping
When connecting piping to the product, install appropriate piping support to prevent
the piping load from being applied to the product.
If piping load is applied, it may cause damage to threaded parts or leakage may
occur from the sealing part.
(3) Motive Medium Supply Pipe [Sm
1
] and Motive Medium Supply Tube [Sm
2
]:
The diameters of the motive medium supply pipe [Sm
1
] and of the valve on the
motive medium supply pipe [Vm] diameter should be at least 15 mm (
1
/
2
in). If copper
or stainless steel tubes are used for the connection from the motive medium supply
tube [Sm
2
] to the PowerTrap, make sure that the tube
’s inner diameter is at least 8
mm (
5
/
16
in) but no more than 3 m (10 ft) in length. The inner diameter of the valve
and tube fittings connecting to the PowerTrap
should also be at least 8 mm (
5
/
16
in).
Install a strainer [Km] (at least 15 mm (
1
/
2
in) and 40-mesh or finer) on the
PowerTrap motive medium supply tube [Sm
2
] 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 if installed on a horizontal piping.
Only use steam, compressed air or nitrogen as the motive medium.
The maximum motive medium supply pressure is 0.5 MPaG (75 psig, 5 barg).
When the motive medium is steam, 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 can cause steam leakage, which
results in the PowerTrap
becoming inoperable.
When steam or high temperature air is used as a motive medium, make sure to use
steel pipe for the motive medium supply tube [Sm
2
].
(4) Pressure Reducing Valve on the Motive Medium Supply Piping:
When the motive medium pressure [Pm] is greater than 0.5 MPaG (75 psig, 5
barg), install a TLV pressure reducing valve (such as the DR20) in order to reduce
the motive medium pressure to the PowerTrap. In order to prevent the pressure
from rising at dead end shut off, be sure to install a relief valve between the
(Piping should be
arranged so
condensate does not
accumulate, limiting
piping length to 3 m
(10 ft))
Motive Medium
Supply Pipe [Sm

]
(Condensate will accumulate if the
piping is installed in a vertical
arrangement. Not recommended
even if the piping length is shorter
than 3 m (10 ft).
