TROUBLE SHOOTING
PROBLEM CAUSE CORRECTION
1. Control valve stalled in regeneration A. Motor not operating A. Replace Motor
B. No electric power at outlet B. Repair outlet or use working outlet
C. Defective transformer C. Should provide 12 volts when plugged into outlet,
if not, replace transformer
D. Defective PC board D. Replace PC board
E. Broken drive gear or drive cap assembly E. Replace drive gear or drive cap assembly
F. Broken piston retainer F. Replace drive cap assembly
G. Broken main or regenerant piston G. Replace main or regenerant piston
2. Blank or incomplete LCD display A. Transformer unplugged A. Connect to power
B. No electric power at outlet B. Repair outlet or use working outlet
C. Defective transformer C. Should provide 12 volts when plugged into outlet,
if not, replace transformer
D. Short in meter D. Unplug meter from PC board, if LED lights appropriately,
replace meter assembly.
E. Check battery, should be greater than 3 volts E. Replace battery if less than 3 volts
F. Defective PC board F. Replace PC board
3. Control does not display correct A. Power outage > 2 years A. Reset time of day, replace lithium coin type battery
time of day on circuit board
B. Power outage < 2 years, time of day ashing, B. Reset time of day, replace lithium coin type battery
battery depleted on circuit board
4. No “ltering” display when A. Bypass valve in bypass position A. Put bypass valve in service position
water is owing B. Meter connection disconnected B. Connect meter to PC board
C. Restricted/stalled meter turbine C.
Remove meter & check for rotation, clean foreign material
D. Defective meter D. Replace meter
E. Defective PC board E. Replace PC board
5. Control valve regenerates at A. Power outages A. Reset control valve to correct time of day
wrong time of day B. Time of day not set correctly B. Reset to correct time of day
C. Time of regeneration incorrect C. Reset regeneration time
D. Control valve set at “on 0” D. Check control valve set-up procedure
(immediate regeneration) regeneration time option
E. Control valve set at NORMAL + on 0 E. Check control valve set-up procedure
regeneration time option
6. Odor bleedthrough A. Test for Hydrogen Sulde (H
2
S) on site. A. Hydrogen Sulde bleedthrough
1. Increase frequency of ozone recharge
2. Exceeding ow rate specication - see page 6
3. No ozone present - see Ozone Generator troublshooting
B. No Hydrogen Sulde after unit
Bacteria is source of odor rather than H2S, chlorinate
distribution plumbing and ush completely
7. Momentary reduction of water A. Head of air being expelled to drain A. Reprogram regeneration to a time when water is not
pressure at the start of regeneration being used
OZONE GENERATOR TROUBLESHOOTING GUIDE
SYMPTOM POSSIBLE CAUSE CORRECTION
1. Ozone unit does not turn on A. Unit not wired correctly to relay A. See wiring diagram on page 18
B. Unit not programmed correctly B. See program on page 11. Relay should be programmed
on Time. Usually set to 19 minutes. Duration
should be programmed for 2 minutes less than length
of time to draw ozone to top of lter bed.
C. Blown fuse C. Replace fuse with equally rated fuse, see page 18
2. Unit keeps blowing fuses A. Electrical short in unit A. Visually inspect unit, and check for loose connections.
Inspect printed circuit board for burn marks. Inspect
high voltage wire from printed circuit board to ozone
cell for disconnection or burn marks. Repair any and
all problems prior to placing unit in service or contact
factory for service information
B. Incorrect fuse value and type are B. Replace with appropriate size/type fuse. Refer to
being used Spare/Replacement parts for replacement part
information on page 18
C. Unit is connected to improper power C. Refer to ozone generator manual for correct voltage
source requirements
3. Unit turns on, but no ozone output A. Cell is plugged with a build-up of nitrous A. Rinse cells with warm water and dry completely
byproducts and particulate matter. Usually before replacing
caused by the lack of proper air preparation
B. Water has been allowed to back up into cell B. Replace cell/check valve
C. Frequency driver high voltage lead(s) C. Connect lead(s) to Corona Discharge Cell(s)
is not connected to ozone cell(s)
D. Frequency driver is defective D. Replace circuit board driver
