1. HYDROXZONE OZONE GENERATOR
1.1 INTRODUCTION TO OZONE
The Hydroxzone ozone generator system produces ozone when air is drawn across a special
high-energy vacuum ultraviolet (VUV) lamp, converting some air to ozone and hydroxyl radicals.
A Dynamic Venturi is inserted on the return line, by-passing through a venturi, which creates
suction that draws the ozone/hydroxyl radicals into the water ow, mixing the bubbles as the
water returns to the pool.
It is operated automatically by connecting the Hydroxzone ozone generator system directly
to the circulation pump or plugging into a timer. A check valve is employed to prevent water
owing up to the ozone generator, in the event of system failure.
Although ozone is mainly thought of as a sanitiser, it acts primarily as an oxidiser in the pool
environment. In a typical chlorinated pool, up to 90 percent of the pool’s chlorine may be used
up in reactions unrelated to disinfection. The by-products of these reactions are combined
chlorines. Combined chlorine is the cause of eye irritation, odour and the other unpleasant side
effects of chlorination. When the ozone/hydroxyl radical is used, they oxidize a large portion of
the contaminants, which results in the formation of combined chlorine. The result is that more
chlorine is available for disinfection and less chlorine is required to maintain the pool. Ozone
provides some disinfection, but ozone residual cannot be established, so the use of bromine
primary sanitiser [chlorine, bromine, hydrogen peroxide] is always recommended.

2. INSTALLATION
2.1 PREPARING FOR INSTALLATION
I. Check for and correct all leaks in plumbing.
II. Balance the pool Water
III. Backwash the lter on retrot installation.
IV. Shock the pool. Hydroxzone must be used in combination with and approved/registered
sanitiser
V. Turn pump OFF.
VI. Locate section of plumbing where the Venturi Injector needs to be located.
VII. Venturi Injector must be installed after the lter and any other additional equipment installed
in line (e.g. heater or solar)
VIII. The unit must be mounted out of direct contact with the weather.
IX. Hydroxzone must be mounted on a wall in a horizontal orientation as shown below.
Figure 2.1 Hydroxzone Mounting Position
NOTE: The minimum recommended vacuum at the inlet of the Venturi injector is 2 L/min.
The vacuum can be measure by using a vacuum meter (Waterco’s P/N 72522813). It may
be necessary to install a Ball Valve (not included) in the main line between the Entrance and
Exit of the bypass. The Ball Valve will need to be adjusted to ensure adequate ow through
the bypass.
Multispeed pumps can alter the water ow rate through the pool system. Adjusting the
speed of a Multispeed pump will affect the water ow and the vacuum through the Venturi
Injector.
When making any adjustments to the speed of the Multispeed pump, make sure there is a
minimum vacuum of 2L/min through the venturi injector.
All pools are different. Depending on the hydraulic resistance in the pool system, running a
Multispeed pump on low speed may not create enough vacuum. If this is the case, the pump
speed will need to be increased until the minimum required vacuum is reached.

2.3 INSTALL THE SADDLE CLAMPS (BYPASS)
1. Turn pump OFF.
2. Locate section of existing plumbing in which you choose to install the ENTRANCE leg of
the bypass. Location should be in any accessible area after the pump, but before the lter
(Please refer to Figure 1.1).
3. Install Saddle Clamp Top & Bottom, (and adapters if needed), without bushing, (this will be
used as a guide for your installation hole).
4. Drill a 7/8”/22mm hole through one wall of the pipe, using power drill, being careful not to
drill too deep to avoid penetrating the opposite side of the plumbing.
5. Locate section of existing plumbing in which you choose to install the EXIT leg of the
bypass (Please refer to Figure 1.1). Location should be in any accessible area after the lter,
and heater (if equipped).
6. Repeat steps 3 & 4.
7. Remove both Saddle Clamp Assemblies.
8. Using components listed, mount one Saddle Clamp Assembly on Entrance bypass location
with the INLET side of the Venturi Injector mounted in the Saddle Clamp Bushing, (ozone
ports should be facing upward). Tighten both screws. (refer to Figure 2.2)
9. Using components listed, mount the other Saddle Clamp Assembly on Exit bypass location
with the 15mm x 75mm length (½” x 3”) PVC pipe mounted in the Saddle Clamp Bushing.
Tighten both screws. (refer to Figure 2.3)
10. Attach one end of 20mm (¾”) clear hose to Venturi Injector and secure with a metal clamp.
Attach other end of 20mm( ¾”) clear hose to 15mm x 75mm Length (½” x 3”) PVC pipe and
secure with a metal clamp.
11. Mount the Hydroxzone Ozone Generator on a wall or surface at least above maximum
water level to prevent water from contacting the electrical equipment. Unit orientation will
not affect performance.

20mm (¾”) Ball Valve (not included) in the 20mm (¾”) Hose on the output side of the Venturi
Injector as shown in Figure 1.1. This allows the bypass to be closed when back ushing or
adding DE. It may be necessary to install a Ball Valve (not included) in the main line between
the Entrance and Exit of the bypass. The Ball Valve will need to be adjusted to ensure
adequate ow through the bypass.

2.5 INSTALL HYDROXZONE SUPPLY TUBE
2.5.1. The Hydroxzone unit is supplied with sufcient braided supply tube which may be
cut to length. Ensure sufcient slack in the supply tube. Do not extend the length of
the braided supply tube.
2.5.2. For installations where the Hydroxzone unit is installed 400mm above the highest
point of the lter system, cut the polybraided line to a minimum of 600mm from
the Hydroxzone unit and install the check valve with the concave shape facing the
direction of the Venturi Injector, (Make sure you can blow air through the Check
Valve towards the Injector port). See Figures 2.4.
2.5.3. Cut a 150mm length of ¼” polybraided hose and connect one end to the open
ozone suction point (As shown in illustration 2.5) on the Venturi Injector and the
other end to the OUTLET side of the Check Valve.

2.5.4. Connect the polybraided hose to the barb on the side of the Hydroxzone Ozone
Generator. (see Figure 2.6).
2.5.5. For ooded installations or where the Hydroxzone is installed below 400mm above
the highest point of the lter system, two (2) check valves and a drain must be
installed as follows: (see Figure 2.7)
I. Cut the braided supply tube a minimum of 600mm from the Hydroxzone unit.
II. Install the supplied ¼” barb Tee between the 2 sections of supplied polybraided
hose, with one end of the Tee vacant and pointing to the ground
III. Cut the polybraided hose supply line approximately 200mm further on the
Venturi Injector side of the ¼” barb Tee piece, and install a check valve with the
concave shape facing the direction of the Dynamic Venturi Injector, ensuring the
ow of air from the Hydroxzone unit to the Dynamic Venturi Injector.
IV. Cut the polybraided hose to length, ensuring a length of 200-300mm of braided
supply hose is available to make a drain off the ¼” barb Tee piece
V. Take the 200-300mm piece of polybraided hose supply and cut it in half
VI. Install the second check valve between the 2 pieces of cut supply hose
VII. Connect the 200-300mm piece of hose with check valve installed, and connect
to the base of the Tee – ensuring that the concave shape is facing toward the
vacant end of tube (Figure 2.7). Ensure this drain tube is pointing to the ground.
This will ensure water is able to drain from the supply tube.
VIII. Connect the other end of the braided supply tube to the Dynamic Venturi
Injector’s open nipple. Secure with a black plastic clip.
2.6 Connecting polybraid hose to Hydroxzone

2.6 ELECTRICAL INSTALLATION
Hydroxzone ozone generator is designed to operate on either 120 or 240 VAC, 50/60 HZ.
Connect theHydroxzone ozone generator either to the circulation pump switch or timer.
Hydroxzone ozone generator unit and circulation pump should be started simultaneously. Refer
to national electrical codes or local code grounding and installation procedures for swimming
pool equipment.
Avoid running the ozone unit on short cycles. The useful life of the UV lamp will be reduced if
stop/start operation is performed. Continuous operation of 4 to 8 hour periods per day is highly
recommended.
2-7 Installation on flooded condition
IMPORTANT: Hydroxzone must run when the pump is operational. Damage to
unit may occur if air does not pass through the unit for prolonged periods of
time.
i
CAUTION: Make sure the voltage is the same as prescribed on the side of the
HYDROXZONE ozone generator. Over voltage will void customer warranty.

I pg 09
Hydroxzone Ozone Generator
3. HYDROXZONE MAINTENANCE
The Hydroxzone ozone generator is rated to last 20,000 hours of continuous operation. Start
up and shut down cycles should be kept to a minimum to extend the life of the lamp. The U/V
lamp within the Hydroxzone will provide up to 80% of the maximum output for the system right
up until the lamp stop working.
It is good practice to check the vacuum level on the Dynamic Venturi Injector at regular intervals
to ensure there is sufcient air ow through the Hydroxzone ozone generator.
