easy maintenance.

Be sure to provide the necessary maintenance space for PowerTrap disassembly
an
d repair (see “Maintenance Space and Tolerance Angle for Installation”).
(8) Condensate Receiver [Dh] and Filling Head [A]

Please refer to
“Sizing the Condensate Receiver”.
The size and vent pipe aperture are determined by (a) the amount of flash steam in
the in-flowing condensate (pumped medium) and (b) the amount of pumped
medium held back while the PowerTrap is discharging.
If the receiver is small, the flow of flash steam may cause the condensate to flow
out the vent pipe.
If the vent pipe size is small, the pressure in the receiver will rise, restricting the
pumped medium inflow.
Be sure to select a receiver of the correct size.

The filling head represents the distance from the bottom of the PowerTrap (from
grade) to the bottom of the receiver (shown as [A] in the sketch in
“Steam System
Example
”). Filling heads lower than the minimum filling head of 155 mm (6 in) must
not be used.

If venting flash steam to a high area, an overflow pipe must be installed to
discharge condensate to a safe area.

An overflow pipe should be installed at the side of the receiver.
 Be sure to install a vent pipe and an overflow pipe. Failure to install an
overflow pipe is dangerous, as condensate may spurt from the vent pipe
and could result in burns and other injuries.
 Pipe the vent pipe and the overflow pipe to a safe place such as a pit.
 Piping size of the overflow pipe should be the same or larger than
condensate inlet pipe.
CAUTION
Examples of Overflow Piping for Open Systems
Explanations for overflow piping for open systems
1) If flash steam can be discharged from overflow pipe
Install overflow pipe and vent pipe separately.
2) If flash steam should not be released from overflow pipe (prevent flash
steam release)
Install overflow pipe and vent pipe separately. For overflow pipe, install loop
seal (approx. 300 mm (12 in)). Flash steam release from overflow pipe can be
prevented since water always accumulates at loop seal. Piping size should be
the same or larger than condensate inlet pipe.

Pipe the discharge to a safe place such as a pit.
High temperature steam or hot water may splash.
There is a possibility of condensed hot water dripping from ventpipe
outlet. Make sure to extend to where people do not pass.
