(7) Receiver/Reservoir Pipe and Filling Head.
• Please refer to "Sizing the Condensate Receiver/Reservoir" on pages 14 and 15.
The size and vent pipe aperture are determined by (a) the amount of any 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 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/reservoir pipe of the correct size.
• The filling head represents the distance from the bottom of the PowerTrap (from grade)
to the bottom of the receiver/reservoir.
The standard filling head is 860 mm (36").
When an installation calls for a lower filling head, a filling head of less than 860 mm (36") is
allowable. However, the minimum filling head is 710 mm (30").
• For Open Systems:
- If venting flash steam to a high area, an overflow pipe must be installed to discharge
condensate to a safe area.
- Overflow pipe should be installed at the side of the receiver.
WARNING
There is a possibility of condensed hot water dripping from vent pipe outlet.
Make sure to extend to where people do not pass.

Pipe the discharge to a safe place such as a pit.
High temperature steam or hot water may splash.
･ 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.
