3.1 Ozone Generator
•
The S2Q-OZ will generate sufficient ozone for most spa and hot tub applications subject to the wide variations that
occur depending on operating conditions, chemical control and bather load.
•
Model S8Q-OZ is sufficient for smaller pools and can be used in parallel for larger applications. Sizing will also be
dependent on a wide range of variations including operating conditions, chemical control and bather load.
•
Choose a location for your generator that is accessible to an approved electrical outlet and where the indicator light is
visible.
Note:
Electrical outlets within 10 feet of the tub must have ground fault protection.
•
Leave enough space to allow for removal of the UV lamp for lamp maintenance.
•
As UV lamps can be damaged in shipping and handling, check the lamp before installing your ozone generator by
plugging it into an electrical outlet for a moment. A bluish light should be evident at the ports and the LCD display on the
controller should illuminate.
Your ozone generator should be located in a dry area that is accessible for servicing and at least two feet above the water
level. If the unit can not be mounted at least two feet above the water level, the tubing connecting the generator to the inlet
of the spa or pool must either be installed with a loop to raise it two feet above the water level or be fitted with a check valve
approved for ozone service to prevent water back flow into the generator. When using an optional venturi system to provide
increased air flow, a check valve must be used to prevent back flow into the generator in case the outlet line is blocked.
Select a location two feet above the water level and with access to a properly grounded electrical outlet. The unit can be
mounted vertically or horizontally with the connection ports facing down. Mount the chamber to the wall using the cell clamp
and mounting screws included with your system. If mounting the unit to drywall, use a plug or an expansion butterfly nut to
secure the unit.
Some typical installation procedures are:
3.1.1 Pressure Differential System for Ozone Eduction System Part Number OE-001
Recommended for most spa installations. This simple pre-assembled system utilizes a combination of pressure
differential, venturi and the spas existing air induction piping, offering the most efficient and economical ozone mixing and
distribution, virtually eliminating any gas off. Please note in the illustration below that water from the high pressure side of
the pump is forced through an aspirator or venturi which causes air suction. This air suction pulls ozone in from the ozone
generator thereby mixing the ozone and water at the aspirator where injection takes place. Then the mixed ozone and
water travels through a 3/8” tube to the spas air induction line.On the way back to the air line the ozone and water is
retained in a loop in the 3/8” line to cause thorough mixing and ozone absorption in the water prior to injection into the spas
air line. Reduce the water level until it is below the air induction line (if necessary) to avoid water leakage when making the
connections. NOTE: ozone may cause rubber seals in the system to degenerate. These parts should be replaced with
“Viton” or other material resistant to ozone.

Do not look directly into the ports.ultraviolet light emitted by the lamp can cause burns to unprotected eyes.
