CHAPTER 4

The HDO3 system anticipated results are based on water quality and gallons per minute (GPM) flow rate
and water pressure. Based on desired dissolved ozone levels measured in parts per million (PPM), the
system should be plumbed using either a sidestream or full flow configuration, see Figure 4-1 for desired
ppm level at the suggested gpm flow rate. The sidestream method takes

a portion

of the water from the

main flow (see Figure 4-2) and diverts it into a sidestream through the HDO3 system, then returns the

water back into the full flow.

In a full flow configuration, the water is simply plumbed into the HDO3 system, and then

out of the system to the point of use, see Figure 4-3.

Note: The HDO3 Series systems have specific flow through rates

that must not be exceeded. If the full flow GPM flow rate exceeds the maximum flow through rate of the HDO3
system the sidestream configuration must be used, see Figure 4-1. Dissolved ozone levels may decline from the
anticipated result listed in Figure 4-1, if the system inlet water pressure is less than 20PSI.

NOTES:

• Adequate use of unions and isolation valves is

strongly recommended to facilitate maintenance

and repairs.

• Use Schedule 80 PVC for all plumbing connections

wherever possible. Plumbing size requirements

are dictated by the water flow characteristics of

the system.

•

Make sure to use proper plumbing practices and

secure all plumbing and system equipment

according to local codes.

• Ozone is a powerful oxidizer and will degrade

certain

materials.

Use

ozone-compatible

plumbing materials for section(s) of the system

that will come in contact with ozone dissolved in

water. The following is a list of materials that are

compatible with ozone:

• PVC

• Stainless Steel (300 series)

• CPVC

• Viton

• Kynar

• EPDM

• Teflon

• Concrete

Step 1:

Arrange the HDO3 system according to mechanical print or as dictated by equipment layout and serviceability

considerations. Do not secure the system to equipment pad at this point. Dry fit plumbing as appropriate to
insure proper fit and location before making permanent connections.

Step 2:

Install a tee or plumbing saddle into the main water line for the sidestream configuration (see Figure 4-2).

Step 3:

Remove the PVC plugs (installed at the factory to keep the dissolved ozone probe wet during transportation)
from the inlet and outlet of the HDO3.

Note: The dissolved ozone probe is calibrated to the dissolved

monitor/controller at the factory. The probe

must

not be out of water for more than a 24-hour period to

retain this calibration. If the duration exceeds 24 hours re-calibration may be required.

Step 4:

Plumb a line, from the tee or plumbing saddle for the sidestream configuration or from the main water supply
line for the full flow configuration, to the HDO3 booster pump. For serviceability of the equipment be sure to
install an isolation valve before the HDO3 system booster pump.

Notes: A pressure reducing valve may be

required if the inlet water supply pressure is greater than 20PSI. The full flow configuration can also be
used to re-circulate and atmospheric vessel, although the HDO3 system

must

have a flooded suction to the

inlet of the integrated booster pump. If the HDO3 system operates with out water flow damage may
occur to the booster pump and warranty will be void.

Step 5:

Using a tee or plumbing saddle, plumb from the outlet of the HDO3 back into the main water line for the

sidestream configuration or to the point of use for the full flow configuration. For serviceability of the
equipment be sure to install an isolation valve after the HDO3 system.

Step 6:

Secure the HDO3 system to solid mounting surfaces using appropriate hardware and according to local codes.

Step 7:

Depending on conditions, the vented gas from the contact tank off-gas vent may be directed to an ozone

destruct system or to atmosphere.

Note: Do not direct the tubing to the

suction

side of a pump.

Step 8:

The HDO3 system incorporates a water pressure relief valve (located on the water outlet line of the system) set

at 55 PSI, to protect the dissolved ozone probe. If the water pressure
