Important Safety Information

Proper installation and usage of your Aquatic 2 Spa Ozone Generator is your responsibility. 
Read and follow this owner’s manual carefully for important installation, operation and 
safety information. Basic safety precautions should always be followed, including but not 
limited to the following:
•  Read and follow all instructions.
•  All electrical connections should be made by a qualified electrician.
•  Follow all applicable electrical codes.
•  Be sure the electrical power is shut OFF at the main circuit breaker before installing the 

ozone generator.

•  If the ozone generator electrical connection is to be attached to spa controls, be sure the 

spa controls are protected by a Ground Fault Circuit Interrupter (GFCI). If the Aquatic 2 
is connected to an independent electrical supply a GFCI must be installed between the 
ozone generator and the electrical supply.

•  Do not bury the cord.
WARNING – To reduce the risk of electrical shock, replace damaged cord immediately. 
•  Per UL spa requirements, the Aquatic 2 must be mounted indoors or under a cover 

sheltered from the elements (rain, sun, sprinklers).

•  Mount the Aquatic 2 so that it is inaccessible to anyone in the spa. Never attempt 

servicing when wet.

•  To reduce the risk of injury, the unit should be mounted where it is inaccessible to 

children.

•  Plastic ozone supply tubing is available with the Aquatic 2. Never replace this tubing with 

metal tubing.

•  Do not operate the Aquatic 2 unless sufficient air flow is being drawn through the unit.
WARNING – Short term inhalation of high concentrations of ozone and long-term 
inhalations of low concentrations of ozone can cause harmful physiological effects. Do not 
inhale ozone gas produced by the device. 

PLEASE SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE 

In Accordance With California Regulations -- This Ozone Generator is Solely for Industrial 
Use and Must Be Installed by a Professional. Potential Health Hazard: Emits Ozone.

Installation Instructions

How the Aquatic 2 Works

A2Z Ozone Generators produce ozone gas which is introduced to spa water through suction 
created by the spa injector. Tubing is used to connect the ozone generator to an injector 
or a vacuum port provided by the spa manufacturer. The injector or vacuum ports are 
sources used to pull the ozone gas out of the ozone generator and into the water. At no time 
should water come in contact with the Aquatic 2. To protect the ozone generator from water 
traveling backwards through the tubing connection, the unit must be mounted and plumbed 
as described in this manual. 

Installation Parts

•  1 installation manual
•  1 check valve 
•  5 feet of tubing
•  4 hose ties
•  2 screws and plastic anchor for mounting

Installation Tools and Materials

•  Phillips screwdriver
•  Pliers

Unit Assembly

•  The Aquatic 2 is pre-assembled and ready to install.

Mounting

•  Mount the ozone generator as high as possible within the spa’s protected equipment 

area or outside.

•  Screws are provided for mounting but may not be appropriate for all surfaces. Substitute 

proper mounting hardware as required.

Plumbing – Vacuum System (refer to Figure 1)

•  Most spas are factory equipped with an ozone injector or vacuum port, like the one 

shown in Figure 1. Review your spa’s installation manual to identify the correct ozone 
connection location.

•  If the spa is not equipped with an injector (vacuum source), A2Z Ozone Systems provides 

a wide range of optional installation kits. 

•  Contact A2Z Customer Service for assistance at 502-499-4977 or visit 

www.a2zozone.

com/collections/accessories-1/venturi-injector

 to view our venturi injectors.

Plumbing – Ozone Generator (refer to Figure 1)

•  Connect shorter PVC ozone tubing (8 inch) provided to the hose barb on the ozone 

generator side.

•  Connect other end to the check valve.
•  Connect longer PVC tube to the other end of the check valve and run to the injector. 
•  Observe the flow arrow on the check valve and ensure that the flow direction is into the 

injector vacuum source.

•  Connect the other end of PVC tube to injector suction. Run the spa and pump and check 

the vacuum before connecting PVC tube to injector. 

•  If there is no vacuum at suction then you will need to check the injector or pump water 

flow. 

•  Do not connect ozonator if there is no vacuum at injector suction.
•  Slide hose ties on each end into the tubing.
•  Secure all tubing connections with the hose ties.
NOTE: If the Aquatic 2 is mounted below the water line, run tubing to a point above the 
water line and back down to the vacuum source. Secure tubing in this position.

Figure 1

This diagram represents how the Aquatic Spa 2 Ozone Generator should be installed in 
relation to the hot tub’s water and electric box. Additionally, the venturi injector and check 
valve are on the ozone line. Remember, the spa ozone generator should be mounted as 
high as possible to prevent backflow into the unit.

Electrical

•  Test the GFCI breaker protecting the spa for proper operation.
•  Disconnect power to the spa.
•  Connect the Aquatic 2 cord to the mating connector(s) on the spa control box as 

described in the spa’s installation manual and the provided A2Z Ozone wiring diagram in 
Figure 2. 

•  Where possible, route the power cord away from other electrical lines. Do not run the 

power cord parallel to any low voltage signal wires.

•  Secure the power cord as required to prevent damage.

Operation

•  With the spa filled to the proper level, run the spa controller through several cycles.
•  Verify that the ozone generator turns on and off as required by the controller.
•  The red LED light will be visible from the viewing window on the bottom left.
•  Verify that the gas is flowing into the injector. 

•  There should be no water in the tubing and very small bubbles entering the spa 

through the return.

•  Verify that water does not push past the check valve during any spa cycle.
•  Check for and correct any leaks.

Installation Complete

•  Once properly installed, the ozone generator requires no further user operation. 
•  It will operate automatically with the spa system.

Wiring Diagram

This unit is shipped with the wiring as shown. 110V or 240V can be applied to the black and 
white wires. To match alignment of the white wire of the ozone generator connector with the 
controller box connector. Keep in mind, the white wire can be moved. Mount the unit so that 
the tube, light and wires are toward the ground. Disregard the front label.

Please make sure water will not back into the Aquatic 2 Spa Ozone Generator. Water will 
damage the unit and void the warranty. 

Please check these:
•  Install the Aquatic 2 above water level and as high as possible.
•  Mount the unit so the tube, light and wires are toward the ground (disregard front label).
•  Install the check valve according to the arrow on the check valve (arrow is toward the 

injector).

•  You need an injector for injecting ozone into the spa’s water line. 

•  If you do not have a venturi injector, please contact us for purchasing one. 
•  This unit does not work without an injector.

•  There should be a vacuum at ozone injector suction location.

•  This can be felt with your finger when installing. 

•  Ozone generator should be on only when the spa pump is on. 
•  If your spa did not have an ozonator, then connect ozone electric wire to pump wires.

Troubleshooting

13

Problem

Possible Cause 

What to Do

Cloudy water 

condition even 

though the unit 

appears to be 

operating properly 

Unit and pump not operating 

long enough

Increase operating time (min. 6 hours 

is recommended)

Total alkalinity not correct

Adjust total alkalinity between 8 and 

150 ppm

pH not correctly balanced

Check for proper pH between 7.2 and 

7.6

Not enough suction

Clear any obstruction in the water 

lines or return fitting

Dirty, loose or cracked filter

Check/replace spa filter as needed

Metals or minerals in the 

water

Ozone may react with metals/

minerals in the water causing cloudy 

water. Check alkalinity pH and clean 

filter. Run filtration system and ozone 

24 hours. 

System won’t turn 

on/off 

Water backing into the unit

Mounting the unit as high as possible 

in relation to the spa water level is 
important. There is also a one-way 

check valve provided to prevent the 

back flow of water from reaching it. 

As a secondary precaution, a Hartford 

Loop in the tubing, also hanging 

above water level, will help prevent 

water damage to the unit. 

The red LED not lit 

on ozone generator

No power to the ozonator

Check the electrical connections and 

then the fuse
