Electrical Power Connections; Optional Electrical Connections; System Operation - Ozone Solutions Waterzone Series Installation & Operation Manual

Air Vent
The air vent is located on the top of the Contact Tank.
The 1/2 inch port exiting the air vent will need to be
plumbed outdoors away from human contact or to a
suitable ozone destruct unit, as it will be off-gassing
small amounts of high-concentration ozone. Ozone-
compatible tubing and fittings should be used for this
purpose.
Waterzone systems are configured with an Ozone
Destruct Unit installed on the skid. The gas exiting
this ozone destruct unit should still be plumbed to a
safe location in the event the destruct unit fails for any
reason. It is important that this gas is removed from
human contact and vented to a safe location.
Water Trap Drain
The Water Trap is located on the Ozone Injection Skid.
This water trap will drain any water that may be pushed
from the Venturi Injector toward the Ozone Generator;
this is a protection device for the Ozone Generator.
There may also be a water trap installed to drain any
water from the off-gas vent outlet prior to the ozone
destruct unit.
These water traps may collect a small amount of water
that will need to be plumbed away to a drain. Any drain
tubing must be run DOWNHILL in order to freely drain.
Use tubing with an ID of no less than 3/8 inch, with a
maximum of 5 feet.

SYSTEM OPERATION

IMPORTANT: Read and understand the "Personal
Safety" section of this manual before operating the
Ozone System.
Water Flow
Water flow through this ozone injection system will
be dependent upon the supply water connection to
maintain pressure on the system. The ozone injection
will occur regardless of the rate of flow through the
contact tank, as long as the tank remains full of water.

ELECTRICAL POWER CONNECTIONS

The system requires a 220 Volt, 4 wire, 30 Amp, 60 Hz
single phase circuit. The unit is installed with a NEMA
cord end for easy power up.

OPTIONAL ELECTRICAL CONNECTIONS

CAUTION: Voltage may be present at connection
terminals! Disconnect all power before servicing.
Terminals are provided for connection of external
contacts to control and monitor the system. The
terminals are located inside the System Controller.
Drill holes in the System Controller as necessary for
connection of external control wiring.
These connections may be used optionally as desired.
Some terminals are jumpered from the factory to allow
the system to operate without external connections.
On terminals which are jumpered, the jumper must
be removed upon connection of remote contacts. If
control wires are used in the terminals currently, these
can be run in series with any remote control device of
your choice to power the system remotely.
Higher water usage will result in lower dissolved ozone
levels, while lower water usage will result in higher
dissolved ozone levels. This is due only to the ratio
of ozone to water. Keep this in mind when specific
dissolved ozone levels are required for your operation.
Water Pressure
This ozone injection system will not operate effectively
with water pressures exceeding 50 PSI. If water
pressures are higher, then water pressure should be
regulated ahead of the ozone system so that it can be
adjusted to maintain lower pressures.
If the water will be used for spraying or washing
purposes, the water pressure should be kept below
30 PSI. This is to ensure that the ozone will remain
