Ozone Solutions Waterzone Series Installation & Operation Manual page 9

O3 GENERATOR COOLING WATER IN: is the 1/4
inch brass female NPT fitting on the side of the controller
near the cooling water flow meter. This must be connect-
ed to a consistent water supply of cool fresh water.
O3 GENERATOR COOLING WATER OUT: is the 1/4
inch brass female NPT fitting on the side of the control-
ler near the cooling water flow meter. This is the drain
from the ozone generator cooling loop. This water should
be plumbed safely to a drain.
Water Sample Port
Ozone residual in the water must be checked periodically
to ensure proper operation of the Ozone Injection System.
This is also used to calibrate the dissolved ozone sensor
(if applicable). After the output of the Ozone Injection
System, a small tee with a ball valve should be placed in
the water line. This will allow for samples of water to be
pulled to verify the dissolved ozone level in the water.
ORP Sensor
The ORP probe is shipped uninstalled. This probe is
shipped with a protective cap on the end to keep it pro-
tected from damage, and keep it moist. This probe will be
damaged if it becomes dry.
Read and understand the instructions provided for the
sensor before installing it into the line. Install it only after
all other plumbing for the Waterzone is completed, and
the system is ready to be filled with water.
Dissolved Ozone Monitor
Measures the dissolved ozone level exiting the contact
tank. The black cap needs to be pulled off of the tip for it
to work. Read and understand the provided sensor in-
structions which should have been provided to you if you
purchased this option. The manual will inform you of the
maintenance and calibration of this probe.
ES-600
This monitor is to display an ozone reading measured
from the ambient air. It features a sensor head assy. which
can be located remotely from the main monitor
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 suita-
ble 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.
Some Waterzone systems are configured with an
Ozone Destruct Unit installed on the skid. If pre-
sent, 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 wa-
ter 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.
Electrical Power Connections
The system requires a 120/220 Volt, 4-wire, 40/25
Amp, 50/60 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 de-
sired. Some terminals are jumpered from the fac-
tory to allow the system to operate without exter-
nal connections. On terminals which are jump-
ered, the jumper must be removed upon connec-
tion 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
