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
The trap valve seat port, screen or
piping is 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 is clogged with rust and
scale
Clean or replace with a new screen
