Defective connector Replace connector.
Calibration as
measured at output of
mass flow controller
does not agree with
calibration as
measured at output of
instrument Leak
Mass flow controller not calibrated
Perform a leak check (see
“Servicing” chapter).
Calibrate mass flow
controller
No ozone output Lamp failure Check for blue light when
removing ozone lamp from
ozonator and replace lamp if
light not visible.
Ozonator heater failure Check to see that ozonator is
warm (>50 °C). If not warm,
replace heater or heat power
supply (see “Servicing”
chapter).
Ozonator board failure Replace ozonator board (see
“Servicing” chapter).
Low ozonator output Leak in ozonator or distribution
manifold Check for leaks in ozonator
and manifold system (see
“Servicing” chapter) and
repair leak.
Flow excessively high Check zero air flow valve and
reduce flow.
Ozonator board failure Replace ozonator board (see
“Servicing” chapter).
Weak lamp Check to see that there is a
bright blue light when
removing the ozone lamp
from ozonator, with ozonator
level set to 100%. If not,
replace lamp (see
“Servicing” chapter).
Unstable ozone output Failure of analyzer measuring ozone Repair analyzer.
Leak in system Check for leaks and repair
(see “Servicing” chapter).
Zero air flow unstable Check zero air flow meter.
Lamp failure Replace lamp.
(see “Servicing” chapter).
Defective ozonator board Replace ozonator board (see
