To prepare to install your new automatic parts washer,
choose an unobstructed, level site that allows conve-
nient access for operators and maintenance person-
nel. Sources for water and electrical power should be
located near the installation site. If your machine is
equipped with the optional power brush and hand detail
brush you must also run a compressed air line to the
installing site.
Electrical Connections
NOTE: All electrical installation tasks must be per-
formed by a licensed, professional electrician to ensure
safe and proper operation.The installation must comply
with the National Electric Code and all applicable state
and local codes.
The machine can only operate on the type of electri-
cal power indicated on the machine identification tag.
Read and understand the machine identification tag
to determine the electrical power requirements before
installing the machine.
Connect a Compressed-Air Line and
Accessories
This step is required for machines equipped with the
optional power brush and hand detail brush. If your
machine does not have these options, skip the follow-
ing procedure.
NOTE: To ensure proper operation and to minimize
the possibility of premature component failure, make
sure the compressed air is supplied at 75 to 90 psi. It
is also recommended that an in-line moisture trap and
an in-line lubricator be installed on the main air supply
line. Refer to the documentation provided with the air
brush for more information.
Step 1:
Remove the power brush from the box, install the wire
brush in the chuck and connect the air hose.
Step 2:
Familiarize yourself with the three-way air flow select
valve (See Figure Below) then install a fitting to accom-
modate a connection to your compressed air supply.

Step 2:
Open the right sump cover and feed a water hose di-
rectly into the sump chamber
Step 3:
Fill the sump with water. The sump capacity is 50 gal-
lons.
Step 4:
When the low water level indicator light turns off, the
sump is full. Turn off the water.
NOTE: Monitor the water level carefully - do not
overfill the machine. If you overfill the machine, re-
move excess water using a small submersible pump or a
suitable container.The correct water level is two inches
from the top of the access door when the pump is off.
Step 5:
Close the lid.
Step 6:
Turn the heater timer to the 2 hour position. The sump
will reach operating temperature (160°-180°F) in ap-
proximately one hour.
Step 7:
While the sump water is heating, add the appropriate
quantity of factory approved detergent to the wash
chamber. We recommend mixing the detergent with
warm water in a separate bucket/container and then
pouring the dissolved detergent into the sump.
NOTE: Factory approved detergent is the only deter-
gent approved for use with this automatic parts washer.
It is specially formulated with rust inhibitors and anti-
foaming agents to optimize performance and minimize
maintenance. The use of any other detergent during
the warranty period will void the warranty. In addition,
using factory detergents will extend your 90 day labor
warranty to 1 year.
Step 8:
Close the lid.
Step 9:
Turn the wash cycle timer to 2 hours for the first time
and allow the machine to complete the cycle to thor-
oughly dissolve the detergent into the water.

Main Operating Components
Familiarize yourself with the main operating compo-
nents before operating the machine.
Control Panel
The control panel is located on the front center of the lid
and it contains the controls for the heater, wash cycle,
oil skimmer, turntable and low-water indicator light (See
Figure Below).
HEATER CONTROL
The heater control is a 12-hour timer switch. It controls
the heating element in the sump chamber. The heater
control is thermostatically set at the factory to reach a
high temperature of 180°F. The temperature is adjust-
able using the thermostat (See Section on Thermostat
for Illustration).
WASH CYCLE CONTROL
The wash cycle control is a 60-minute timer switch with
a hold feature. When set between 1 and 60 minutes,
the timer automatically shuts off the pump and turntable
when the wash cycle is complete. When set to hold,
the pump and turntable run continuously until manu-
ally shut off.
OIL SKIMMER CONTROL
The oil skimmer control is a 30-minute timer switch that
controls the automatic oil skimmer system.
TURNTABLE SWITCH
The turntable switch is a simple rocker switch that en-
ables you to disconnect power to the turntable motor.
Set to ON, the turntable rotates during the wash cycle.
Set to OFF, the turntable does not rotate during the
wash cycle.The switch is useful for washing large parts
that would otherwise impede turntable rotation.
LOW WATER INDICATOR
The low water indicator light illuminates if the wash
solution in the sump is low.
SECTION 3: OPERATION
Lid Safety Switch
The lid safety switch is located on the front edge of the
cleaning chamber. This feature ensures that the water
pump and turntable motor do not operate if the lid is
open or unsecured. The safety switch is adjustable.
ADJUSTING THE LID SAFETY SWITCH
To adjust the safety switch, remove the control panel,
adjust the switch and replace the control panel. When
properly adjusted, you should hear a slight ‘click’ as
the lid closes.

SECTION 3: OPERATION
The frequency at which you must clean the debris
screen depends on machine usage. In general, you
should clean the screen before operating the machine
each day.
NOTE: Never operate the machine without the debris
screen in place and never remove the screen while the
machine is operating. The screen is specially sized to
filter particles that could clog the spray nozzles or dam-
age the water pump. Operating the machine without
the debris screen in place could cause spray nozzle
clogging, or water pump failure.
Air Flow Valve (Optional)
The air flow valve is located on the right rear corner of
the machine. It is a three-way ball valve that controls
the flow of compressed air to the power brush and the
hand detail brush (See Figure Below).
Power Brush (Optional)
The power brush is located on the right front corner of
the machine (See Figure Below).
NOTE: The power brush is a standard component on
the model H20-2518 Deluxe Edition. It is available as
an option on the base model H20-2518.
USING THE POWER BRUSH
With stiff stainless steel bristles turning at 1800 RPM,
the power brush easily removes carbon deposits, old
gasket material, or other tightly adhered materials from
parts before washing.
To turn on the power brush, position the air flow select
valve appropriately, then push the power brush lever
lock forward with your thumb and squeeze the throttle
lever to control the speed of the brush.
WARNING: Particles dislodged by the power brush
could cause serious injury to your eyes. Always
wear approved eye and hand protection when using
the power brush.
Detail Brush and Flow Regulator
(Optional)
The detail brush is located on the front inside wall
of the wash chamber. The flow regulator is located
on the right rear corner of the machine (See Figure
Below). The detail brush uses a continuous flow of
hot cleaning solution through its nylon bristles to
help you clean delicate or lightly soiled parts. The
flow regulator controls the flow of cleaning solution
through the detail brush.
ADJUSTING THE FLOW
OF CLEANING SOLUTION
The flow of cleaning solution through the detail brush
is pre-set at the factory. If you need to adjust the flow,
pull out the flow regulator knob, then rotate it clockwise
to decrease the flow or counterclockwise to increase
the flow. After adjusting, push the knob back in to lock
it. (See Figure Above)

SECTION 3: OPERATION
The automatic water fill system uses the low-water
shut-off proximity switches to open and close a water
solenoid valve, which automatically maintains a proper
water level in the sump. The figures on the previous
page describe the operation of the automatic water fill
system.
DETERGENTS
AND ADDITIVES
Detergents
Manufacturer's detergents are the only detergents
approved for use with our Automatic Parts washers.
They are specially formulated with rust inhibitors and
anti-foaming agents to optimize performance and
minimize maintenance. The use of any other detergent
during the warranty period will void the warranty.
To monitor the relative concentration of the detergent
in the wash solution, periodically examine the wash
solution in the sump chamber for the following
indicators:
• Rust inside the machine: not enough
detergent
• Excessive foaming: not enough detergent
• Thick, white residue on parts after
washing: too much detergent
To maintain proper detergent concentration under
typical operating conditions, add detergent each month
after cleaning the sump chamber. Follow recommended
detergent quantities. Use pH kit to determine the proper
amount of detergent to use. If you need help interpreting
test results, contact customer service.
Rust Inhibitor Additive
Factory detergents protect the entire inside of your
machine against the degenerative effects of water
evaporation. A rust inhibitor additive actually evaporates
with the water and continuously coats and protects
metal surfaces, even while your machine is sitting idle.
For more information, contact your distributor or call
customer service.
PREPARING THE MACHINE

TESTING INDIVIDUAL
COMPONENTS
NOTE: The following troubleshooting procedures re-
quire the use of a volt/ohm meter. If you are not familiar
with using a volt/ohm meter do not attempt to perform
the following troubleshooting procedures. If you need
assistance please contact your distributor.
Wash Cycle, Heater and Skimmer Timers
Step 1:
Disconnect power to the machine
Step 2:
Remove the timer from the control panel and discon-
nect all wires.
Step 3:
With the timer in the OFF position, test for continuity
using the ohm meter.
If there is continuity the timer is no longer functional;
replace the timer.
Step 4:
With the timer in the ON position, test for continuity
using an ohm meter.
If there is not continuity the timer is no longer functional;
replace the timer.
Lid Safety Switch
Step 1:
Disconnect power to the machine.
Step 2:
Remove the switch from the control panel and discon-
nect all wires.
Step 3:
With the switch fully open (not depressed), test for
continuity.
If there is continuity the switch is no longer functional;
replace the switch.
Step 4:
With the switch fully closed (depressed), test for con-
tinuity.
If there is not continuity the switch is no longer func-
tional; replace the switch.
Heating Element
Step 1:
Disconnect power to machine.
Step 2:
Remove the cover from the heating element and ther-
mostat enclosure (Two 5/16" screws).
Step 3:
Detach the two power leads from the heating element
(See Figure Below).
Step 4:
Use an ohm meter to measure the resistance of the
heating element. The resistance should be approxi-
mately 10 ohms; if not, replace the heating element.
Thermostat
Step 1:
Disconnect power to the machine.
Step 2:
Remove the cover from the heating element and ther-
mostat enclosure (Two 5/16” Screws).
Step 3:
Detach the two power leads from the thermostat (See
Previous Figure).

Step 4:
Using a large flat-head screwdriver, pry the thermostat
out of the mounting bracket, then remove it from the
machine (See Figure Below).
Step 5:
Set the thermostat to 120°F, warm it to just above 120°F,
then test for continuity.
If there is continuity the thermostat is no longer
functional; replace the thermostat.
Step 6:
Allow the thermostat to cool to room temperature, then
test for continuity.
If there is not continuity the thermostat is no longer
functional; replace the thermostat.
Start Capacitor
Step 1:
Disconnect power to the machine.
Step 2:
Remove the turntable motor cover (Two 5/16" screws,
See Figure Below).
SECTION 4: TROUBLESHOOTING
Step 3:
Visually inspect the start capacitor (See Figure Be-
low). If it appears swollen or deformed, it is no longer
functional; replace the start capacitor.
Step 4:
If the start capacitor is not visibly failed, remove it from
the motor bracket, disconnect the wires, and test it for
shorts using an ohm meter.
If the ohm meter reads approximately 1 ohm, the
start capacitor is no longer functional; replace the
start capacitor.

SECTION 5: MAINTENANCE AND REPAIR
MAINTENANCE AND REPAIR
To ensure optimum performance and trouble free op-
eration, observe the following maintenance schedule
consistently.
Daily Maintenance
• Checkthewaterlevel;addwaterifnecessary.
• Cleanthedebrisscreen.
Weekly Maintenance
• Detergent Concentration Level: Check deter-
gent level weekly to maintain concentration level
which decreases when water is added. The pH
level of this detergent must be in accordance with
the detergent manufacturer's recommendation.
• Removeoilfromthewashsolutionusingtheoil
skimmer system (See Using the Oil Skimmer
System).
• Examine the spray nozzles; clean and align if
necessary (See Cleaning and Aligning the
Spray Nozzles).
• To maintain the integrity of the exterior nish,
wipe down the exterior of the machine using
a spray degreaser and a soft, damp cloth. TO
PREVENT ELECTRICAL COMPONENT FAIL-
URE, DO NOT SPRAY THE MACHINE WITH
WATER.
NOTE:Spray degreaser and a damp cloth will usu-
ally remove all dirt and grime from the machine. For
particularly stubborn soap deposits, use a soft cloth
dampened with warm solution from the wash chamber.
Monthly Maintenance
• Drain and clean out the sump chamber
(See Cleaning out the Sump).
Semi-Annual Maintenance
• Lubricate the pivot on the turntable motor
assembly with machine oil or anti-seize.
Using the Oil Skimmer
The oil skimmer is most effective if used when the clean-
ing solution is cool, and after it has been sitting for at
least thirty minutes. The frequency at which you must
remove the oil from the wash solution will depend on
machine usage. Under typical operating conditions you
can expect to remove the oil once each week.
To remove oil from the cleaning solution, perform the
following procedure:
Step 1:
Allow the machine to sit idle for at least 30 minutes to al-
low the oil to float to the surface of the wash solution.
Step 2:
Ensure that the oil collection container is in place (See
Figure Below), then turn the skimmer switch to the 30-
minute position.
Step 3:
Allow the oil skimmer to operate until it is no longer
extracting oil from the cleaning solution.
Tip: While extracting oil from the cleaning solution,
oil will flow off the wiper blades in a fine continuous
stream. Water will flow off the blades in droplets. Once
droplets begin to flow off of the wiper blades, stop the
skimmer motor.
Step 4:
When the skimmer motor stops, dispose of the oil in the
collection container in accordance with local, state and
federal regulations, then replace the container.
Cleaning and Aligning the Spray Nozzles
To ensure optimum cleaning performance, it is important
that you examine the spray nozzles periodically and
clean and align them if necessary.
To clean a plugged nozzle, remove it from the spray pipe
and use a small wire brush to free the nozzle of any
obstructions.When you replace the nozzle on the spray
pipe, make sure you align it according to the following
diagram to maintain a proper spray pattern.
