How the System Works
The system consists of
three major components: Ozone generator, in-line mixer and filter module:
The ozone generator either plugs into a standard receptacle
(120v-60hz model) or is hardwired (230v-60hz model). It has an air pump which provides
compressed air to an ultraviolet ozone producing lamp, thus producing compressed ozone.
The mixer installs into the well pump water feed pipe to your
holding tank. The ozone gas is routed from the ozone generator, through the mixer, to the
filter module within your holding tank. When your well pump turns on to provide water to
your tank, the mixer automatically diverts and mixes the ozone gas into the incoming well
water before the water enters your tank.
The filter module hangs below the water surface inside your
holding tank, includes a 100 square foot filter, a lift pipe and a diffuser (bubble
maker). The ozone gas from the mixer is fed to the filter module diffuser, which makes
millions of tiny ozone saturated bubbles that rise up the filter module lift pipe, mixing
the ozone with the water and drawing water through the filter at the rate of about 10
gallons per minute. As the ozone saturated bubbles exit the lift pipe, the bubbles rise up
through your holding tank water, continuing the ozone/water adsorption process and
circulating the contents of your holding tank.
HOLDING TANK SIZE
One TWTS-101 system is designed to purify the water in a tank
of up to 10,000 gallons with normal contaminant levels. Larger tanks will require multiple
As a rule, the maximum water usage should never exceed 25% of
the tank capacity in a 24 hour period. A typical family of 4 uses about 350 gallons per
day and should therefore have a minimum 1500 gallon tank.
Prepare the filter module for installation into the tank:
- Attach the handle/diffuser assembly to the filter top by
feeding the diffuser hose down into the filter module lift pipe and attaching the quick
- Attach the stainless steel chain (provided) to the captive
chain on the handle by crimping the end link onto the top link of the handle chain.
- Connect the Norprene hose (dull black rubber like hose) to the
barb located on top of the filter module handle. Using the black wire ties provided,
gently tie the Norprene hose at one foot intervals to the stainless steel chain. Do not
over tighten the wire ties as this will crush the hose and reduce ozone flow.
tank for installation of the filter module:
- Drill a 3/16 inch hole through the manhole flange nearest the
center of the tank.
- Insert the provided #8 bolt through the manhole flange from
the outside of the manhole and secure in place with one of the #8 nuts provided. Do not
discard second #8 nut, this will be used later.
- On the side of the manhole flange, at the 9 o'clock or 3
o'clock position (12 o'clock is the side of the manhole closest to the center of the tank
as viewed from the top), drill a 5/16 inch hole through the manhole flange.
Install the filter module in the tank:
IMPORTANT: THE BOTTOM OF THE FILTER MODULE SHOULD BE AT A
MAXIMUM DEPTH OF 8 FEET BELOW THE HIGHEST TANK WATER LEVEL, BUT NOT CLOSER THAN 1/2 FOOT
FROM THE BOTTOM OF THE TANK TO PREVENT STIRRING UP SEDIMENT.
- Slowly lower the filter module down into the water. For deep
tanks (water depths of 9 feet or more), position the bottom of the filter module 8 feet
below the highest water level. For shallow tanks (water depth less than about 8-1/2 feet),
lower the filter module down into the tank until it touches bottom, pull back up 1/2 foot.
- Remove excess chain and attach chain to the #8 bolt with
second #8 nut.
- Insert the 90 degree hose barb fitting through the 5/16 inch
hole in the side of the manhole flange from the outside of the manhole, and attach the
3/16 inch black Norprene hose to the barb, cutting off excess Norprene hose as
The mixer installs into the well water feed pipe to your
tank. For above ground tanks, the mixer should be installed at about the same vertical
level as the filter module (the bottom of the mixer should be at about the same level as
the bottom of the filter module). For buried tanks, the mixer can be mounted anywhere
above the ground. The mixer can be mounted in any orientation.
The mixer has a 1 inch PVC slip input (lower) and a 1-1/2
inch slip output (upper). To maximize the effectiveness of the mixer, 1-1/2 inch pipe
should be run from the top of the mixer, up the side of the tank to the point of water
introduction into the tank. If this is not possible, the 1-1/2 inch pipe should be run at
least 3 to 4 feet from the top of the mixer before converting to the existing water well
feed pipe, thus providing a "mixing chamber" for the ozone gas.
Glue the mixer in place in the well water feed line:
- Determine vertical location of the mixer.
- Cut the water pipe in appropriate location. Using PVC
fittings, glue the water feed pipe (from the well pump) to the bottom input of the mixer.
NOTE - MAKE SURE THE MIXER IS CORRECTLY POSITIONED WITH THE ARROW ON THE BYPASS CHECK
VALVE POINTING IN THE DIRECTION OF WATER FLOW.
- Using appropriate PVC fittings, install 1-1/2 inch PVC pipe
from the top of the mixer to the tank water input fitting.
Ozone hose installation:
- Using the glossy black vinyl hose (50 foot coil supplied),
route the hose from the 3/16 inch barb in the manhole to the top 0 psi (white) check
valve, wrapping the vinyl hose around the 1-1/2 inch water feed pipe for a neat
installation. NOTE: If it is cold outside, heating the vinyl hose slightly with a match
will make it easier to slip onto the barb fittings.
- Connect the 6 psi (red) check valve hose to the venturi
The mixer assembly is subject to freezing as is the water
feed pipe from the well. In freezing climates, insulate well. Use "heat tape" in
OZONE GENERATOR INSTALLATION
The ozone generator can be mounted up to 200 feet from the
holding tank; 50 feet of black vinyl hose is supplied which is more than adequate for most
installations. Consult factory if additional hose and connectors are needed.
The generator construction is rain tight and can be mounted
indoors or outdoors. Good ventilation is required since the generator creates heat.
- Remove generator can lid.
- Mount the can to a solid vertical surface (wall, etc.) with
the 3 screws supplied. Two screws are used to mount the can hanging tabs, and one screw is
used to attach the can back to the mounting surface through the 1/4 inch hole provided in
the back of the can.
- Write installation date on sticker located on the inside of
the can lid.
- Route the 3/16 black vinyl hose from the ozone generator to
the lower 0 psi (white) check valve of the mixer. Be sure to route the hose so it will not
become accidentally damaged.
- If your generator is cord connected, plug the ozone generator
into a properly grounded, grounding type receptacle. Use a waterproof receptacle/plug
cover if installed outdoors. If your generator is the 230v hard wired version, wire
according to local and national codes.
STARTING UP YOUR SYSTEM
Recheck your installation to verify that it is correct. Turn
ON the ozone generator. You should hear a faint hum - this is the air pump. A faint
blue-green glow should be visible through the lens near the top center of the generator
can - this indicates the UV lamp is ON and the system is producing ozone. NOTE: The UV
lamp may not fire up immediately if the ambient temperature is below 40 degrees F, and may
never fire in extreme cold. However, once lit, the lamp will stay lit in extreme cold.
Proceed to the tank manhole - you should see a full pattern
of bubbles rising up from the filter module. This may take a few seconds to develop since
the entire ozone hose system must be pressurized.
Now turn ON your well pump. The bubble pattern inside the
tank should decrease or stop completely. This indicates that the ozone gas is correctly
being diverted to the mixer. If you see no change in the bubble pattern in the tank,
recheck your installation and make sure the ozone hose is correctly installed and the
mixer is installed with the flow arrows pointing in the direction of water flow.
If the installation is correct, it is possible that your well
pump cannot create enough pressure to fully activate the mixer. With the well pump ON,
pull off the black Norprene hose from the venturi eductor barb - you should be able to
feel suction on the venturi barb indicating that the mixer is working. Reinstall the
If no suction is detected, check for debris in the mixer. The
mixer bypass valve is factory set to 15 psi. If your well pump cannot produce more than 15
psi, the water flow into your tank will all pass through the venturi eductor and your well
water feed flow rate will be reduced. This is no cause for alarm as reducing the water
flow rate will not harm your well pump.
