IMPORTANT: Don't force the ratio adjuster
sleeve above the maximum setting of 1%
(1:100) or below the minimum setting of 0.2%
(1:500) (Fig. 16).
Note:
Settings in the gray zone (below 0.5%
or 1:200) will cause the pump to take
longer to prime. For faster priming, set
the mixing ratio to the maximum
setting (1% or 1:100). After the pump
is primed, reset the mixing ratio to the
desired setting.
The ratio adjuster sleeve can be moved
with water flowing, while the injector
is under water pressure or when the
bypass knob is in the bypass position
(Fig. 16).

8.
Start the engine. Move the throttle to the Fast
position and disengage the parking brake.
9.
Aerate normally.
10. When you're finished injecting, add one (1)
quart or more of fresh filtered water to the
chemical tank. Operate the HydroJect 3000
Aerator and injection system until the fresh
water is gone.
11. Rinse the chemical tank with fresh filtered water.
IMPORTANT: Additives allowed to remain in
an inactive injector can dry out and foul or
damage the lower end at the next start-up.

Application Rate
1.
Adjust the HydroJect 3000 Aerator to a
three-inch (3") hole spacing. Refer to the
Maintenance section in the HydroJect 3000
Aerator Operator's Manual.
2.
Determine how many ounces of additive per
1000 square feet you want to apply.
3.
Refer to the Application Rate table on the
following page to determine the ratio adjuster
setting and tank mixture concentration (in
percent) needed to apply the desired number of
ounces of additive per 1000 square feet. Use 100
percent concentration whenever possible to
reduce additive handling and mixing.
4.
Set the ratio adjuster to 1:100 (1.0%), 1:128
(0.8%), 1:200 (0.5%) or 1:500 (0.2%) as
required.
5.
Add the required number of ounces of additive
to the chemical tank, then fill the tank with fresh
filtered water as required to the very top of the
neck, then stir.
Note:
The decal on the injector is just a
starting point. Further calibration may
be required. See the Calibration
section.
Example
Say you want to apply an additive at an approximate
rate of five (5) ounces per 1000 square feet.
1.
Refer to the 3.00" Hole Spacing table shown
below. The table shows that to apply additive at
a rate of five ounces per 1000 square feet, the
ratio adjuster should be set to 1:128 and the tank
mixture concentration should be 30 percent.
2.
Set the ratio adjuster to 1:128.
3.
Carefully add the additive to the chemical tank
until it reaches the 30 (percent) line.
4.
Fill the tank with fresh filtered water, then stir.
