Suggested ozone concentration and run-time in Swimming Pools

Ideal pump run time on 24 hour cycles. If user chooses to run pump on 12-hour cycle time then

water circulating rate should be once each 3 to 4 hour period. The pump should re-circulate the

total volume of pool water through the injector at least once each 4 hr period for maximum

liters.

If the pool volume is say 60000 liters then the pump should be capable of re-circulating the

water at a rate of at least 15000 liters per hour. This way, the total volume of water through the

pool will be passing through the injector at least once each 4 hour period. Less pump run time

for the minimum liters. Use Sodium Bromide if additional chemicals are required. Dosage is 20 g

per 1000 Liters of water every 6 months

INSTALLATION

OZONE GENERATOR PLACEMENT:

Install ozone generator in a clean, dry area with a good ventilation.

Ozone generator should be placed above any water level for the following reason; if you were to

lose pressure in the venturi vacuum, gravity will cause water to travel down the ozone output

tube and enter into the ozone generator. Please look at provided drawing for more information.

If water height less than 5 feet. (1.5 m)

Note:

Be sure to place ozone generator in room temperatures 40 and 100 Deg. F (4.5 to 38 Deg. C)

Select a location for the ozone generator that is as close as possible to the ozone injection point.

Situate the unit in a manner suitable for convenient electrical access. The MODEL SP-SERIES

enclosures is not rain proof, so it is important to choose a location that will keep the system

away from direct weather and excessive heat.

The mounting holes are located on the back of the ozone generator for convenient wall

mounting. Mounting hardware is not provided.

The basic installation method for the MODEL SP-Series system is INJECTOR MANIFOLD

PLUMBING CONNECTIONS. INJECTOR MANIFOLD MUST BE ASSEMBLED (ordered from our site

as well).

Picture of typical Venturi Injector Manifold

Refer to the ‘Venturi injector Installation’ diagram and follow the instructions below if the ozone

is being injected directly into the full flow of the pool’s return line:

•Identify the pool water supply line after the pump, filter and heater and Tap into this

point. The ozone injection point should be the last component in line and as far as

possible from the injection point of the residual chemical.

•Glue in the proper injector manifold, noting the direction of flow (indicated by an arrow

on the injector). Once the injector is installed, the vacuum may be adjusted as described

in the ozone operation Section.

DETAILS OF VENTURI INJECTOR MANIFOLD:

Attention: Install venturi with bypass valve on water recirculation pipeline. Arrow on venturi

MUST be set as the same direction as water flow.

Turn water pump on and close the by- pass valve until vacuum is created at venturi input.

Note1: Use the installed flow-meter to check vacuum -2 to -3 PSI (-0.14 to -0.21 bars) or place

finger over end of venturi valve to feel vacuum while adjusting the by-pass venturi valve. At this

point, the air is injected into the water line; you will observe the air as bubbles in the water of

the swimming pool.

MAIN POWER:

Use the power cable provided to connect the SP-Series to a properly rated and

grounded receptacle. If the ozone generator will be used where water is present, a

ground fault circuit interrupter must protect the circuit.

TUBE CONNECTION AND START UP:

Connect silicone tube (if you use oxygen generator or oxygen tank or external air compressor) to

ozone generator (Air IN) and direct it away from hot and humid air to the ozone cell. This will

serve as oxygen, or fresh air for ozone production.

Connect ozone generator PTFE tube (OZONE OUT) to venture injector manifold.

Install a check valve 10 inches after ozone out let tube fitting (even the venturi has internal

check valve). You may do this by cutting tube ten inch after OZONE out fitting. Connect both

ends of cut tubes to the check valve. Please direct the arrow on the check valve toward venturi.

START, first the swimming pool water re-circulation pump. Make sure you have vacuum at the

venturi via a gauge and test it by putting your finger on the venturi opening. You should feel a

small suction, this is what is needed to get the ozone production out of the unit and inject it into

the pool piping system. Check Flow meter, air flow should indicate at least 2 LPM. Now connect

the PTFE tube from the venturi to the ozonator and turn on the power in the internal panel of

ozone generator.

The ozone indicator light up and the fan should turn on. Increase power to the Cells by turning

the ozone control knob clockwise. Please refer to the charts above for the approximate ozone

concentration for your size of pool.

OZONE GENERATOR OPERATION

System Running Time

On residential pools, the ozone generator should operate for six to eight hours per day.

Normally, the ozone system will run whenever the pool filtration system is operating. Since

commercial pool and spa filtration systems normally operate 24 hours a day, the ozone system

will run continuously on a commercial pool.

Understanding Your Water

If a high concentration of any mineral (such as calcium or iron) exists in the water, it is necessary

to treat it before starting the ozone system.

Note: This should be required only when the pool is drained and refilled.

If the water is clean and clear, the ozone system may be started immediately. If the water is

dirty and cloudy, it is recommended that it is drained and the filters thoroughly cleaned before

refilling and starting the system.

Note: It is not recommended that an in-ground pool be drained in the winter or after the first

rain of a season. Use a shock treatment instead of draining to avoid the possibility of severe

damage resulting from “floating” the pool out of the ground.

Ozone and Bromine

Ozone has a short “half-life”, which means it dissipates and re-transforms into oxygen very

quickly. Therefore, a small residual of another disinfectant must be maintained. We recommend

the use of bromine in indoor pools. Bromine residual will act as a buffer when the ozone system

is not operating. Bromine needs to be maintained at only 1.0 PPM (parts per million) so that the

trace amount of the product in the water will not be noticed. Chlorine will also work as a

residual oxidizer and may be used effectively in conjunction with the ozone system.

Ozone and Chlorine

For outdoor pools, we recommend the use of chlorine to supplement the ozone. Chlorine

residual will act as a buffer when the ozone system is not operating. Chlorine needs to be

maintained at 1.0 to 2.0 PPM (parts per million).

Water Preparation

To properly prepare the water for the ozone system, make the following adjustments and

maintain the levels outlined below:

Bromine 1.0 PPM or Chlorine 1.0 to 2.0 PPM and pH 7.2 -7.6

Total Alkalinity 100-150 PPM

Calcium Hardness 200-350 PPM

Note: If any unusual reactions are experienced when ozone is introduced into the water (such as

abnormal color or odor), please wait a few days to give the ozone and filter system time to

work.

Algae

Always maintain the recommended residual levels of bromine or chlorine (at least 1 .0 PPM) to

help control algae formation. Brushing poolside once a week is also effective, as is any algaecide.

Shock Treatment

If an unusually high bather load causes cloudiness in the water, it is recommended that a

chlorine shock treatment used to assist the ozone in cleaning the water. Routine, periodic

shocking is recommended to prevent buildup of organic contaminants, especially with indoor

pools.

MAINTENANCE - OZONE GENERATOR

Clean the ozone generator cabinet’s air filter:

This filter must be cleaned regularly. Depending on the location of the unit, it may be necessary

to clean the air filter monthly. The filter elements are located on the bottom of the cabinet (see

illustration below). This is the air intake element for the cooling fan and may therefore require

the most frequent cleaning. The element may be cleaned with soap and water and should be

dried completely before reinstalling.

Note: In a clean environment, this procedure may only need to be performed every three

months.

IMPORTANT: CLEAN THIS FILTER REGULARLY! FAILURE TO DO SO WILL PROMOTE OVERHEATING AND

WILL VOID THE WARRANTY!

PROCEDURE

TURN OZONE GENERATOR OFF.

CLEAN FILTER SCREEN WITH WATER AND SOAP AND DRY IT WITH A CLEAN TOWEL.

INSTALL BACK THE SCREEN.

TURN ON THE OZONE GENERATOR.

BE SURE SCREEN DOES NOT TOUCH FAN BLADE.

MAINTENANCE - SWIMMING POOL FILTER

Ozone will keep the water much cleaner than any other type of water purification system. This is

due to the fact that ozone neutralizes body oils and soaps. After ozone kills the bacteria, the by-

products of the process are oxygen, carbon dioxide and filterable solids. Since filterable solids

are usually at higher levels than with conventional disinfection processes, the filter will have

more work to do. Keeping the filter clean will make a noticeable difference in the clarity of the

water. It is recommended that a regular filter cleaning schedule is established, or poor water

flow through the filter will result. This will have a direct effect on the amount of ozone that

enters the water.

A word of caution: There is extremely high voltage inside the ozone generator. If you suspect

a problem, disconnect the power to the unit at the service disconnect box or main electrical

panel and immediately contact your swimming pool maintenance technician. Inspect the

ozone delivery line check valves daily for water seepage and strongly recommend replacing

the injector check valve yearly.

Check valves

Two check valves are available for the ozone delivery system, One where the ozone tubing

attaches to the ozone generator and one where it attaches to the injector. The purpose of
