AGW–4015/4025/4045 Installation & Operations Manual
4A-2. Other External Components
Main Power Switch: 1.
Activates water pump and
supplies power to ozone generator.
Ozone Power Switch: 2.
Activates ozone
generating equipment.
Injector Vacuum Gauge: 3.
Indicates Vacuum of
the ozone in the injector system.
Back-Pressure Gauge: 4.
Indicates back-
pressure in the main flow loop (after the injector).
Flow / Back-Pressue Adjustment Valve: 5.
Controls total system water flow, back-pressure,
and vacuum level.
Inlet Pressure Gauge: 6.
Indicates inlet pressure
in the main flow loop (before the injector).
Dissolved Ozone Monitor/Controller: 7.
Displays dissolved ozone level in water and can
be set for ozone generator to maintain desired
ozone level. (See Section 4E and ATI Dissolved
Ozone Monitor/Controller owner’s manual for
further information.)
4B. Quick System Start-Up
Presumes unit is tuned to its present application.
(Follow Detailed System Start-Up Section 4C).
Turn Main Power switch to ON. Pump On green 1.
light will illuminate. Allow one minute for system
to stabilize.
Turn Ozone Power switch to ON.
2.
Check System Vacuum Gauge. Adjust Flow/ 3.
Back-pressure adjustment valve until gauge
reads approximately -3 to -7 in. Hg. vacuum.
Ozone Power green light will illuminate upon
reaching approximately -5 in. Hg.
4C. Detailed System Start-Up
Read completely before starting system.
Check for proper electrical and water 1.
connections.
Switch Main Power ON (Pump On green light
2.
will illuminate), allow pump to run for one
minute as water level in mixing tower fills and
stabilizes.
If the mixing tower doesn’t fill with water then
3.
the pump needs priming. Turn off the Pump
Power, DO NOT RUN PUMP DRY (pump seal
failure will result). Insure the water supply
hose is full of water and the water source has
sufficient flow capacity for the pump. Turn on
the Pump Power. Repeat until the mixing tower
has filled, stabilized and water is circulating.
Switch Ozone Power ON.
4.
Check System Vacuum Gauge. Adjust Flow/ 5.
Back-pressure Adjustment valve until gauge
reads approximately -5 in.Hg. vacuum. The
back pressure gauge should read at or above
18 psi for AGW–4015/4025 and at or above 8
psi for the AGW–4045.
Ozone On green light will illuminate upon
reaching approximately -5 in. Hg.
NOTE:
Applications with elevated head pressures
will raise inlet and back pressures. The
above values are minimum operating
pressures.
4D. System Shut-Down / Freeze Protection
Turn OFF Ozone Power switch. 1.
Turn OFF Main Power switch. 2.
Remove hoses (if applicable) and allow water 3.
to drain from system (a small amount of water
will remain in the ozone degas chamber).
Freeze Protection: It is recommended that
4.
the AGW–4015/4025/4045 be protected from
freezing temperatures. If this is not possible,
the pump must be drained by removing the 1/2"
drain plug located underneath the pump (See
page 8). WARNING: Pump damage will occur
if pump is not drained before unit is stored in
freezing temperatures or for extended periods
of time. A small heater may be used to prevent
remaining water in the system from freezing.
4E. Standard Operating Procedures
The following chart provides ozonation time
estimates to charge tanks ranging in size from
300 to 2,000 gallons using the AGW–4015/4025.
NOTE: Water temp. and oxidizer load will affect
ozone levels and max PPM.
