Installation & Operation Manual
Microzone 300 & 500
Corona Discharge Ozone Generators

• Read and follow all instructions
•Save these Instructions
• Before attempting any electrical connections, be sure all power is off at the main circuit
breaker.
• Install all electrical equipment at least ve feet from any open body of water using
non-metallic plumbing.
• Install check valves and a Hartford Loop to prevent water from contacting the electrical
equipment.
• Be sure to bond (ground) the system using the copper bonding lug on the bottom of
the ozone generator. The system should be bonded with solid copper wire conforming
with all local, state and national electrical codes.
Two aspects of ClearWater Tech ozone generators represent potential
dangers, ozone gas and high voltage electricity.
OZONE GAS - WARNING: Low concentrations of ozone can cause
irritation to the eyes, throat and respiratory system.
HIGH VOLTAGE - WARNING: ClearWater Tech ozone generators operate at high
voltages. If contact is made with operating high voltage components electric shock will occur.

Compare the ozone system equipment to packing list provided. Before beginning any
installation procedures, thoroughly inspect all components for damage. If damage is noticed,
promptly notify the freight carrier and request an on site inspection. Inspect all packing
materials for small parts before discarding.
• When placing ozone system components, make sure to consider safety, maintenance
requirements, local building and re codes.
• To determine the most favorable placement, the following should be considered:
• Located downstream of all other existing water system components.
• Located upstream of the residual sanitizer injection point (if so equipped).
• The pH adjustment chemical injection point should be located downstream of the
residual sanitizer injection point (if so equipped).
• Location of ozone generator should be no more than 8 feet from point of use.
• Adequate protection from weather, dust and excessive heat. Ambient temperature
range: 20ºF to 85º F continuous.
NOTE: Equipment installed in extreme environmental conditions will void manufacturers warranty.
• The ozone generator is equipped with a 0 to 100% variable OFF/ON switch. Depending
on the amount of ozone required you may adjust the ozone output control switch
counter clockwise for minimum output or off and clockwise for maximum output.
• The ozone generator is equipped with a main power indicating light next to the variable
switch. This light will be illuminated when the switch is not in the off position.
• The ozone generator will not produce ozone until airow is initiated.
Disconnect power from unit before any maintenance procedures.
• Check valve – replace diaphragm check valve, annually.
• Reaction chamber - replace the reaction chamber every 3 years.

START-UP
EQUIPMENT PLACEMENT
The microzone ozone generators may
be used to inject or diffuse ozone
into water. The injection method
requires a venturi injector to draw the
ozone from the ozone generator and
into the water line. ClearWater Tech
has developed the PRO Series Sys-
tem with magnetic drive pump, program-
mable timer and venturi to provide a
suitable suction port for the injection
method (see Figure 1). For typical spa
applications the spa manufacture has
provided an “ozone ready” suction port,
which eliminates the need for additional
equipment (see spa manual for
installation). The diffusion method requires
a pressurized air source, which feeds air
through the ozone generator and out to
an atmospheric body of water. A diffuser
stone provided with the Microzone ozone
generator is used for increased mixing
of ozone in solution. For this applica-
tion ClearWater Tech has developed the
OAS7 compressor, with programmable
timer to provide the pressure required
(see Figure 2).
Note:
Regardless of application, water back ow
prevention devices such as a check valve
and Hartford Loop should be implemented
with the use of the Microzone ozone
generators (see gure 3).

OZONE GENERATOR
Microzone 300
Step 1: Mount the Microzone ozone generator to a suitable at surface, using the two
self-tapping screws provided. NOTE: The distance from the Microzone to the
injection port should be no more than 8 feet.
Step 2: Attach one end of the supplied tubing to the ozone outlet port of the Microzone
generator and secure with a hose clamp provided.
Step 3: Coil the tubing to create a “Hartford Loop” above the water line. Insert the check
valve provided at the highest point of the Hartford Loop (see Figure 3).
Determine orientation of the check valve by blowing through it, ow should be
directed to the point of use.
Step 4: Attach the other end of the tubing to the injection port and secure with the hose
clamp provided.
Step 5: Plug the Microzone into a suitable outlet. If the PRO Series system is being used,
the Microzone may be plugged into its switched outlet provided. NOTE: All
equipment wiring and grounding must comply with all local electrical codes.

Step 1: Mount the Microzone ozone generator to a suitable at surface, using the two
self-tapping screws provided. NOTE: The distance from the Microzone to point
of diffusion should be no more than 8 feet.
Step 2: Cut a suitable length of the supplied tubing, attach one end to the air prep outlet
of the pressurized source used. Attach the other end to the air inlet port of the
Microzone and secure with a hose clamp provided.
Step 3: Attach one end of the supplied tubing to the ozone outlet port of the Microzone
and secure with the hose clamp provided.
Step 4: Coil the tubing to create a “Hartford Loop” above the water line. Insert the check
valve provided at the highest point of the Hartford Loop (see Figure 3).
Determine orientation of the check valve by blowing through it, ow should be
directed to the point of use.
Step 5: Attach the opposite end of the tubing to the barbed tting of the diffuser stone
provided.
Step 6: Plug the Microzone into a suitable outlet. If the OAS7 is being used the
Microzone may be plugged into its switched outlet provided. NOTE: All
equipment wiring and grounding must comply with all local electrical codes.
