clockwise, the amount of ozone being produced de-
creases and the LED's go down. If no LED's are lit, no
ozone is being produced.
The variable output control is included because some
applications may not need the full output of the CD10/
AD. Rather than off-gas the excess ozone, the output
can be adjusted to fit the needs of the particular applica-
tion. There may also be occasions when the need is tem-
porarily reduced such as when the water level is lower
than usual. In some water applications, the ozone out-
put may need to be reduced to minimize off-gassing of
excess ozone. If an ozone test kit determines that there
is too much residual ozone in the water, the ozone out-
put should be reduced. Conversely, if the ozone does
not appear to be doing its job completely, the output can
be increased. The variable output control can also be
used to adjust ozone output based on seasonal, tem-
perature or water usage variables.
Ozone Generator Maintenance
CAUTION: There is extremely high voltage inside the
ozone generator. If you suspect a problem, disconnect
the power to the unit at the service disconnect box or
main electrical panel and immediately contact your dealer.
Inspect the ozone delivery line check valves daily for
water seepage and replace the injector check valve
yearly.
• Clean the ozone generator cabinet air filter.
This filter must be cleaned regularly. Depending on
the location of the unit, it may be necessary to clean
the air filter monthly. The filter element is located on
the bottom of the cabinet (see illustration). This is
the air intake element for the cooling fan and may
therefore require the most frequent cleaning. The
element may be cleaned with soap and water and
should be dried completely before reinstalling. Note:
In a clean environment this procedure may only need
to be performed every 3 months.
IMPORTANT: Clean this filter regularly. Failure
to do so will promote overheating and will void
the warranty.
• Check Valves
Two Kynar
®
check valves are built into the ozone de-
livery system: one where the ozone tubing attaches
to the ozone generator and one where it attaches to
the injector. The purpose of these check valves is to
prevent water from backing up into the ozone gen-
erator. The Teflon
®
ozone delivery line(s) should be
inspected daily to insure water is not flowing back
into the ozone generator. Check valves should be
replaced yearly. Note: The only time it is possible for
water to flow back toward the ozone generator is
during a system shutdown. Always inspect for water
seepage during this time.
• Regenerating the Desiccant in the Indicating
(visible) Chamber
Check to see that the air dryer is warm. This indi-
cates that it is working. If the air dryer is not working,
call your dealer. The visible indicator cartridge is 25%
desiccant beads which should be blue in color. If they
are clear to white in appearance, check to be sure
that the unit is working. When the desiccant gran-
ules become clear to pink in appearance they have
absorbed too much moisture and must be dried to
regain their efficiency. To dry the desiccant beads,
follow these steps:
1. Disconnect the power to the CD10/AD.
2. Remove the four cover retaining screws from the
top rear and bottom front of the unit. Tilt the cover
up from the bottom over the top of the unit and
carefully pull the plug from the LED circuit board
built into the cover. Remove the cover.
3. With a slot head screwdriver, loosen the fitting
at the bottom of the indicating chamber where
the flexible tubing attaches to the chamber's el-
bow fitting.
4. Loosen the fitting at the bottom inside of the unit
where the brass tubing goes out the bottom of
the unit into the external control loop. Lift the car-
tridge up and out of the unit.
5. Unscrew the top threaded cap from the cham-
ber. Spread the desiccant evenly on a cookie
sheet and bake at 350° in an oven. Check often.
Once the desiccant granules regain their blue
color, remove from the oven.
6. Return the desiccant granules to the cartridge,
recap and reverse the above steps to replace
the chamber.
• Dielectric Tube
The dielectric tube is located in the reaction cham-
ber of the ozone generator. This tube should be in-
spected periodically and cleaned if necessary. Once
each year remove the reaction chamber and inspect
the dielectric tube for debris. If the tube is clean and
free of any debris, oil or dirt, it may be replaced and
no further maintenance is required. If the tube is dirty
or cracked, it must be inspected and cleaned.
Cracked dielectrics should be replaced. Please con-
sult your dealer as the improper installation of the
dielectric may cause safety problems.
Since the air that is introduced into the reaction cham-
bers is high quality, the dielectric tube should remain
clean for at least one year before inspection is re-
quired.
