Physical Set Up:
1. Set unit in desired locaon.
2. Aspects to consider when deciding on placement:
• Clearance for general use
• Locaon of drain
• Emergency exit paths or egress
• Access to control box
• Connecons for water and electricity
3. Use a level to make sure the unit is stable and
leveled in all direcons [Figure 5.1].
4. Adjust leveling feet as necessary by rotang them
clockwise/counter-clockwise.
5. Connect unit to electrical supply.
Plumbing Connecons:
1. Connect water source to solenoid valve ng
inlet (located under control box). Fing is 3/8"
[Figure 5.2].
2. Connect the soluon source to the hose barb of
the Venturi Injector (located under water inlet)
using 1/4" PVC tubing [Figure 5.2].
3. If necessary, adjust the diluon rao using the
included metering ps and test [Figure 5.3].
• The smallest metering p is a yellow p with a
small tube aached [Figure 5.3]. This tube can
be trimmed to alter the diluon rao.
• Full length capillary tube results in a diluon
rao of approximately 1:670 at 30-50 psi water
inlet pressure.
• To adjust injector, turn the bypass screen
clockwise unl soluon ows at a desired
range. (See page 21 for more informaon.)

Motor Speed Adjustment
The speed of the motor is controlled by a variable
frequency motor drive. As the drive decreases the
frequency of the motor, the RPMs decrease. The V.F.
drive displays the Hz. on a small display and the knob
next to it adjusts the Hz. The worm gear reducer has a
20:1 rao.
Default: 1750 RPM at 60 Hz.
To Adjust the Speed:
1. Open the control box.
2. Acvate the sensor to turn on the motor.
3. As the motor is spinning, the unit will display the
operang speed in Hz.
4. Turn the knob counter-clockwise to decrease the
Hz, therefore decreasing the RPMs. Turning the
knob clockwise will increase the RPMs [Figure 6.1]
5. Adjust the Hz. on the variable frequency drive to
the desired brush speed. The minimum frequency
is 15 Hz and the maximum is 60 Hz Clean Logix
recommends 70 RPM/48 Hz.

Brush RPM Formula
The formula for calculang Speed in RPM from Drive
Frequency in Hertz is:
[Motor Nameplate RPM] x [Drive Frequency (Hz)]
÷ [Motor Nameplate Frequency (Hz)] ÷ [Gear
Reducon]
Example:
• Motor Nameplate RPM = 1750
• Motor Nameplate Frequency (Hz) = 60
• Gear Reducon = 20
• Drive Frequency (Hz) = 48
1750 x 48 ÷ 60 ÷ 20 = 70 RPM
The formula for calculang Drive Frequency in Hertz
from Desired Speed in RPM is:
[Desired Speed RPM] x [Gear Reducon] x [Motor
Nameplate Frequency (Hz)] ÷ [Motor Nameplate
RPM]
Example:
• Desired Speed in RPM = 70
• Gear Reducon = 20
• Motor Nameplate Frequency (Hz) = 60
• Motor Nameplate RPM = 1750
70 x 20 x 60 ÷ 1750 = 48 Hz
Brush Direcon
By default, the rotaon direcon for the sole brush is
clock-wise. To reverse the direcon switch 2 of the 3
motor lead wires (T1, T2, or T3).
See electrical schemacs on pages 18-19 for more
informaon.

The following maintenance procedures are
recommended for normal use. Units which see a high
amount of use should be inspected more frequently.
Weekly:
• Check unit for proper sensor funcon and brush
rotaon.
• Ensure grate is secure and funconing properly.
• Inspect brushes for damage or wear. Check for
missing or deformed bristles.
• Inspect electrical cords and plumbing for
damage.
• Inspect and test funcon of emergency stop
switches.
Monthly:
• Check all fasteners to ensure they are ght.
• Ensure warning labels and decals are present
and in good condion.
• Inspect grate spring assemblies (M1896) and
spring balancer bearings (M1904, M1905) for
wear
• Inspect motors, gearboxes, and reducers for
signs of oil leakage.
• Inspect electrical enclosure for signs of water
intrusion.
• Inspect sensors for damage.
• Inspect moving parts for damage or wear.
Quarterly:
• Inspect structure for cracked welds or bent
components.
Gear Reducer:
• The gear reducer is supplied lled to capacity
with Mobil Cibus SHC 634 NSF H1 Food Grade
or equal synthec oil.
• The synthec lubricaon provided is good
for ambient temperatures -10°F - 105°F and
is compable with standard compounded
oil.
• Oil should be changed every 2 years (or 6,000
operang hrs.)
• Designed with a bladder type vent system:
• Consists of an internal bladder that
seals the oil chamber from the outside
environment at all mes - as pressure
builds, the bladder contracts keeping the
internal pressure to a minimum.
• Advantage: The internal oil chamber is
completely sealed, ensuring oil is not
released causing contaminaon in the
applicaon.
Motor:
• Inspect at regular intervals.
• Verify the mounng bolts and couplings to
ensure that they are ght and properly adjusted.
• Motor bearings are sealed and not
re-greasable.
• Bearings should be replaced approximately
every 5 years for 8 hr./day service.

F002 Fault Code on Variable Frequency Drive:
Cause: Power may have been cycled to the unit
while it was “ON”. To solve:
1. While power is sll applied, turn the unit “o”
by pushing down hard on the e-stop buon
2. Wait at least 5 seconds, then pull the e-stop
buon out again. DO NOT stand on the
walkway grate during this process.
3. The unit should now be ready for use.
Cause: If the brushes stop suddenly during normal
use and the fault is displayed, the Motor Current
Sensor set point may be too low. To solve:
1. Turn the set point adjusng screw clockwise ½
turn to raise the set point and re-test.
Please contact your equipment representave
or manufacturer for further support.

1. Shut down the unit (see page 7)
2. Shut OFF the sanizer supply and remove
pressure from the line.
3. Using a small phillips screwdriver, loosen the set-
screw from the solenoid to the control box.
4. Using a 7/16” socket wrench, remove the bolts
holding the solenoid bracket to the unit.
5. Pull the assembly away from the unit and unscrew
the Venturi injector and solenoid assembly from
the spray bars.
6. Unscrew the Venturi injector from the 3/8” pipe
nipple.
7. Take a 1/4” socket wrench and remove the
solenoid from the solenoid bracket. The insides of
the solenoid and Venturi can now be accessed and
cleaned to remove any debris or residue.
