AGW-4015/4025/4045 Skid-Mounted Ozone Sanitation Systems
4B. Quick System Start-Up
Presumes unit is tuned to its present application. (Follow
detailed start up section 4C).
1. Turn Main Power switch to ON. Pump On green light will
il lu mi nate. Allow one minute for system to stabilize.
2. Turn Ozone Power switch to ON.
3. Check System Vacuum Gauge. Adjust Vacuum Ad just-
ment 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 sys tem.
1. Check for proper electrical and water connections.
2. Switch Pump Power ON (Pump On green light will il lu -
mi nate), allow pump to run for one minute as water level
in mixing tower fi lls and stabilizes.
3. If the mixing tower doesn’t fi ll with water then the pump
needs priming. Turn off the Pump Power, DO NOT RUN
PUMP DRY (pump seal failure will result). Insure the wa-
ter supply hose is full of water and the water source has
suffi cient fl ow capacity for the pump. Turn on the Pump
Power. Repeat until the mixing tower has fi lled, stabilized
and water is circulating.
4. Switch Ozone Power ON.
5. Check System Vacuum Gauge. Adjust Vacuum Ad just-
ment valve until gauge reads approximately -5 in.Hg.
vacuum. Ensure that the back pres sure gauge is at or
above 18 psi for AGW-4015/4025 and at or above 8 psi
for the AGW-4045.
Ozone On green light will il lu mi nate upon reach-
ing approximately -5 in. Hg. NOTE: Ap pli ca tions with
el e vat ed head pres sures will raise bypass and back
pres sures. The above values are minimum op er at ing
pressures. If the system is out of specifi ed operating
parameters, see Flow Ad just ment In struc tions below.
System Flow Adjustment Instructions
To make water fl ow adjustments to the AGW-4015/4025
while enabling optimum ozone mass-transfer, please follow
these steps:
1. With the unit running, observe the water fl ow.
2. Adjust fl ow/back pressure valve (the red gate valve) to
achieve 18 psi for AGW-4015/4025 and 8 psi for the
AGW-4045.
3. Next, adjust the vacuum adjustment valve to read -5
in. Hg.
4. Multiple iterations of adjusting both the fl ow/back pres-
sure valve & the vacuum adjust valve may be required to
achieve settings as close as possible to those described
in steps 2 & 3.

4D. System Shut-Down / Freeze Pro tec tion
1. Turn OFF Ozone Power switch.
2. Turn OFF Main Power switch.
3. Remove hoses (if applicable) and allow water to drain
from system (a small amount of water will remain in the
ozone degas chamber).
4. Freeze Protection: It is recommended that the AGW-
4015/4025/4045 be protected from freezing tempera-
tures. If this is not possible, the pump must be drained
by re mov ing the 1/2" drain plug located un der neath the
pump (see page 8).
WARN ING: Pump dam age will
occur if pump is not drained before unit is stored
in freezing tem per a tures or for ex tend ed 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 pro vides ozonation time es ti mates
to charge tanks ranging in size from 300 to 2,000 gal-
lons using the AGW-4015/4025.
Note: Water temp.
and oxidizer load will affect ozone levels and max
PPM.

There are two ways to measure and/or control the
amount of ozone in the water:
Dissolved Ozone Monitor/Controller
By far the most accurate way to measure and control the
ozone in the water, a dissolved ozone monitor/controller may
be used to ensure that the water is completely charged before
starting the timing of the cycle, as well as providing a continu-
ous monitor for observation. In addition, it can be used to con-
trol the ozone system so that the tank of water can be main-
tained continuously and stays charged at the exact amount
determined by the adjustable set-point; it will cycle the ozone
system on and off as needed to maintain the set-point.
