Ideal Installation Schematic
Installation
Check that steam supply is shut off. Ensure that
1.
all system pressures are off and trap is cool before
opening.
Remove steam trap from piping by disconnecting
2.
the inlet and outlet Tri-Clamp
®
and slipping the trap
from the line.
The trap may be installed horizontally or vertically
3.
with discharge downward. The preferred installation
is in the horizontal position as close as possible to
the equipment being drained. Whenever possible,
position the trap below the unit being drained.
Piping should be the same size as the trap connec-
4.
tion. To avoid excessive backpressure, discharge
piping should not be smaller on short runs. For
longer lines, use one size larger.
A full-ported shut-off valve upstream is recommend-
5.
ed to allow isolation for servicing. A shutoff valve
downstream will protect against back flow from the
return line during servicing.
A strainer should be installed with a blowdown valve
6.
immediately upstream of the trap to protect it from
grit, scale and other foreign matter.
A test valve outlet and pressure gauges should be
7.
provided to check trap operation where condensate
discharge is piped to a return line.
For freeze protection, the trap should be installed
8.
vertically with discharge downward, as shown
above. Discharge as close to drain connection
as practical and discharge to atmosphere directly
through a short pipe. A vacuum breaker upstream
may be require to provide complete drainage.
