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 ow 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.

Warning!
Hot discharge from the trap may cause severe
burns. Shut off steam supply and make sure that the
trap is cool to touch before repairing or inspecting.
The trap can be maintained without disturbing the 1.
piping connections. Ensure that the trap is isolated
- upstream and downstream - before attempting to
dismantle it. ALLOW THE TRAP TO COOL BE-
FORE DISMANTLING.
The Steriow disc trap can be cleaned or repaired 2.
by removing the disc and leaving the body in the
pipe line.
Before loosening the cap, the trap must be isolated 3.
from both, live steam lines and condensate return
lines. Open the blowdown valve to relieve trapped
pressure and allow time for the trap to cool.
Remove the cap and disc.4.
Dirt and deposits can cause erratic operation. Disc 5.
can be removed from inspection and sealing sur-
faces can be wiped with a cleaning solvent. Periodic
cleaning of the disc and seat will facilitate trouble-
free performance. DO NOT USE ABRASIVES /
CORROSIVE MEDIA FOR CLEANING.
If surface is scratched or worn, replace with a new 6.
factory-lapped disc. Only the disc and seat are
subject to wear. A worn disc can be replaced and
slight seat wear can be corrected by resurfacing a
lap plate.
Lubricate the cap threads sparingly with anti-seize 7.
compound, taking care not to apply to disc or seat
surfaces.
Tighten cap until rmly seated, approximately 80 - 8.
85 ft-lbs. DO NOT OVER-TIGHTEN.
