8. Adjusting Temperature Setting
The temperature setting can be easily adjusted.
CAUTION
Instructions for Adjusting Temperature Setting
1. First close the external valve from which the steam and condensate flow to the trap (the
"inlet isolation valve"), followed by then closing the external valve to which the condensate
flows from the trap (the "outlet isolation valve"). Wait until the pressure between the inlet
isolation valve and the trap equals atmospheric pressure (when the trap body temperature
cools to room temperature). Do not remove the cap nut unless the trap is isolated from and
is not subjected to steam pressure.
2. Hold the cover with one wrench and use another wrench to slowly loosen and remove the
cap nut. Remove cap nut slowly to allow any residual pressurized steam to leak from the
trap interior through the threads of the adjustment screw and the cover.
3. Hold the adjusting screw in place with a flat-head screwdriver and remove the locknut
slowly in case of any additional steam leakage.
4. Use a flat-head screwdriver to turn the adjusting screw to adjust temperature. To raise the
temperature setting, turn the adjusting screw counterclockwise. To lower the temperature
setting, turn the adjusting screw clockwise. Refer to the set temperature adjustment chart
for the number of turns required from the "0" position to reach the desired temperature.
5. After completing the adjustment, replace the locknut. Hold the adjusting screw in place with
a flat-head screwdriver and tighten the locknut securely.
6. Replace the cap nut and tighten it to the proper torque (see page 13).
7. First fully open the outlet isolation valve, followed by then slowly opening the inlet isolation
valve – carefully checking for any steam leaks that might occur. In the event steam leaks are
detected, immediately close the inlet isolation valve, then the outlet isolation valve, and
repair the source of leakage.
8. Check the temperature setting by observing an inline temperature sensor or by measuring
the temperature at the wrench flat on the trap's inlet side at least 30 minutes after supplying
steam with the new setting. The trap set temperature will be approximately 10 to 20 °C (20
to 40 °F) higher than the surface reading. If the resultant temperature is not as desired,
repeat procedure from step 1 above.
Standard Factory Setting ("0" Position):
The standard "0" position is the position where point (A), the
bottom of the adjusting screw slot is even with point (B), the
top surface of the cap.

• To prevent possible injury, always relieve pressure from trap before
opening to adjust the temperature setting.
• Always wear heat-insulated gloves and eye protection for the following
instructions. Failure to do so may result in burns.
