Category Cause
Procedure
1. The exhaust is
abnormal
• Air-locking or vapor-locking has occurred; in the case
of a closed system, the exhaust pipe is connected to
the condensate reservoir pipe, but the condensate
may not be exchanged for the medium inside the
PowerTrap
for the following reasons:
1. There is a U-shaped pipe between the exhaust port
and the condensate reservoir pipe
2. The exhaust pipe has a diameter of less than 15 mm
(½”)
3. There is no air vent for steam on top of the
condensate reservoir pipe or the steam equipment
If (1), (2), or (3): Change the pipe or install an air vent
(see pages 12 – 13)
• The distance from the ground to the highest point on
the exhaust pipe is too great (over approx. 3 m [10 ft])
For the GP:
Add a steam trap to the exhaust pipe at a point just
above where the exhaust pipe exits the body of the
unit
For the GT:
Add piping connecting the exhaust pipe to the
condensate inlet pipe between the reservoir pipe
and the strainer, being sure to install a check valve
on the piping to prevent backflow of condensate
from the condensate inlet pipe to the exhaust pipe
D.
Faulty
piping
2. The filling head is
insufficient
3. The condensate
inlet pipe is too
small
4. Not enough
condensate is
flowing through the
condensate inlet
valve
• Normal condensate flow will not be obtained if the
filling head is smaller than that in the original design;
the recommended filling head is 630 mm (25")
• Normal condensate flow may not be obtained if the
condensate inlet pipe is too small or the valve on the
condensate inlet pipe is a needle valve or one with a
small Cv value
• The pipe and stop valve size must be increased to the
design pipe size, and a full bore ball valve or gate
valve must be used
