Troubleshooting
NEVER apply direct heat to the float.
The float may explode due to increased internal pressure, causing accidents
leading to serious injury or damage to property and equipment.
When disassembling or removing the product, wait until the internal
pressure equals atmospheric pressure and the surface of the product has
cooled to room temperature.
Disassembling or removing the product when it is hot or under pressure may
lead to discharge of fluids, causing burns, other injuries or damage.
When the product fails to operate properly, use the following table to locate the
cause and remedy.
Problem Cause Remedy
No condensate is
discharged
(blocked) or
discharge is poor The float is damaged or filled with condensate Replace with a new
float
Trap valve seat port, screen or piping are clogged
with rust or scale Clean parts
The product operating pressure exceeds the
maximum specified pressure, or there is
insufficient pressure differential between the trap
inlet and outlet Compare
specifications and
actual operating
conditions
Air is discharged
or leaks from the
trap outlet
(blowing)
(air leakage) Rust and scale have accumulated around the trap
valve seat or beneath the float Clean parts
The trap valve seat is damaged Replace with a new
trap valve seat
The float is deformed or coated with scale Clean or replace with
a new float
The separator is installed above the maximum
allowable inclination Correct the
installation
Air is leaking from
sealing surfaces Gasket deterioration or damage Replace with a new
gasket
Improper tightening torques were used Tighten to the proper
torque
Water is mixed in
with the air from
the separator
outlet Air flow velocity is too high Take steps
necessary to lower
the air flow velocity
Review causes listed above in “No condensate is discharged…” section
and follow the appropriate remedy
Separator outlet
pressure drops or
desired flow rate is
unachievable The screen for 15
– 50 mm (
1
/
2
– 2 in) is clogged
with rust and scale
Clean or replace with
a new screen
