Burner Fault Cycles. (off and
ON) Cracked tube. Pressure increases
>525 torr, Burner faults.
Cycle repeated as
temperature and pressure
reset. Replace broken tubes.
Burner Fault Cycles (off and
ON) Leak in Burner. Pressure increases
>600 torr, Burner faults.
Cycle repeated as

Problem Possible Cause Diagnosis Corrective Action
Pump is noisy High-pressure dry piston. Pressure in the reaction cell
is unacceptably high and the
pump is getting audibly
noisy. Change sleeve/seal.
Pump Doesn’t Start Dry piston seals have
recently been changed. Pump fuses blow
immediately after changing
the seals and sleeves. Dry piston requires break-in
time of a few minutes after
seals are changed.
Pump Doesn't Start Pump switch off (dry piston
pump must start from
atmospheric pressure). Locate pump switch on
pump and verify position. Turn ON switch.
Fuses Blow on Startup Emulsified oil (worn seals
and head on dry piston
pump). Inspect oil for integrity. Change pump oil, and plug
unit into wall to run for 10-15
minutes.
Water in Pump Cracked coalescing filter. Milky yellow oil in the pump
window. Change coalescing filter and
pump oil.
Reaction Cell Pressure High chemical trap clogged. Remove trap from the
vacuum line and confirm
expected pressure readings. Change chemical trap.
Reaction Cell Pressure High Leak in ozone generator. Air regulator falls rapidly to
zero when turned off. Replace ozone generator.
