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.
WARNING
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.
CAUTION
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 trap 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
Deterioration or damage to gaskets
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…” 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
