Table 1: Troubleshooting (for best results follow the table order)
Problem (Indication) Possible Cause Corrective Action
Connect unit to power source
Turn power source breaker on
Reset power source G.F.C.I.
a. Unit is not supplied power
Verify power source voltage is
within unit specification
b. Unit door switch is open Close unit door
c. Unit power switch is in off position Turn power switch on
1. Unit does not start
(main power light is off and no
sound is coming from the unit)
d. Unit circuit breaker is tripped Reset circuit breaker
Connect unit to vacuum source
(injector)
Adjust injector to provide more
vacuum
a. Inadequate vacuum is supplied to
unit
Fix leak or obstruction in plumbing
between injector and unit
b. Unit S.S. check valve has failed Clean or replace S.S. check valve
c. Unit vacuum switch has failed Replace vacuum switch
2. Unit is in vacuum fault
(vacuum light is on)
d. Unit vacuum regulator requires
adjustment or has failed
Call service department for
assistance
Reduce supplied cooling water
temperature and/or increase flow
rate
a. Unit thermal switch has tripped
Obstruction or scaling in cooling
block assembly (clean or replace)
3. Unit is in high temperature fault
(high coolant temperature light is
on)
b. Unit thermal switch has failed Replace thermal switch
4. Unit is in backflow fault
(water backflow detected light is on)
a. Water has returned from injection
point and triggered unit back flow
float switch
Disconnect ozone line between
injector and unit at ozone output
fitting, drain BFPD vessel, and
replace SS check valve
a. Unit flowmeter valve is closed Adjust flowmeter valve open
b. Unit jumper(s) at TB1 are removed
(optional system control hookup, e.g.
flow switch and/or ambient O3)
Re-install jumper(s) and/or verify
system control(s) are operational
c. Unit fuse is blown Replace fuse
Verify unit plumbing between
oxygen concentrator and pressure
switch is securely connected
Replace compressor air filter
Rebuild compressor
d. Unit pressure switch is not active
Replace oxygen concentrator
e. Unit orifice is plugged Clean or replace orifice
f. Unit solenoid valve(s) has failed Clean or replace solenoid valve(s)
g. Unit flowmeter ball is stuck on
bottom of sight tube
Repair or replace flowmeter
5. Unit does not flow gas
(flowmeter at bottom of scale)
h. Unit vacuum regulator requires
adjustment or has failed
Call service department for
assistance
6. Unit ozone production does not
start
(both
ozone power and vacuum
lights are off)
a. Unit jumper at TB4 is removed
(optional external ozone control
hookup, e.g. ORP or dissolved O3,
directly wired or through 5-Pin)
Re-install jumper and/or verify
external ozone control is
operational
a. Unit variable ozone output control
setting is too low (optional feature)
If so equipped, increase ozone
output setting
b. Leak in plumbing that dilutes
applied ozone dose
Fix leak in plumbing (inside unit
and/or between unit and injector)
Replace unit compressor air filter
Clean or replace unit orifice
Clean or replace unit check valve
Rebuild unit compressor
c. Low gas flow and/or low oxygen
concentration
Replace unit oxygen concentrator
d. Unit ozone cell has reached
service life or failed
Replace ozone cell
7. Unit does not provide effective
sanitation
(both
main power and ozone power
lights are on)
e. Unit ozone power supply has failed Replace power supply
