SECTION 2: INSTALLATION
BEFORE YOU BEGIN
To prepare to install the machine, choose an unob-
structed, level site that allows convenient access for
operators and maintenance personnel. 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 installation site.
If you have any questions regarding the installation,
please contact your distributor
STEP 1: MAKE ELECTRICAL
CONNECTIONS
NOTE: The machine can only operate on the type of
electrical power indicated on the machine identification
tag. Read and understand the machine identification tag
to determine the electrical power requirements before
installing the machine.
All machines require a suitable user-supplied power
cord and a fused disconnect.
WARNING: Electrical shock could cause serious
injury or death. For 230V and 460V machines, all
electrical installation tasks must be performed 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.
STEP 2: 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
following 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.
We also recommends an in-line moisture trap and an
in-line lubricator on the main air supply line. Refer to
the documentation provided with the power 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 3:
Connect the shop compressed-air line to the machine.
Step 4:
Connect the hose from the power brush to the air flow
select valve.
Step 5:
Hang the power brush on the bracket mounted along
the right side of the machine.
STEP 3: CONNECT A
WATER LINE
A dedicated water line simplifies the filling process
and allows you to maintain the appropriate water level
much more easily. If you do not wish to connect the
machine to a dedicated water line, skip this step.
The APW is equipped with a water supply inlet valve
through which you can connect the machine to a dedi-
cated water line. The valve is located at the left rear
corner of the machine.
If you wish to connect the machine to a dedicated wa-
ter line, keep in mind that the machine is designed for
portability and some maintenance tasks require that
you move the machine. DO NOT make a permanent
connection from your shop water supply to the machine.
To connect the machine to your shop water supply,
install a 1/2"NPT (male) by 5/8" (female) connection to
the water supply inlet valve, then connect to a nearby
water spigot using a suitable burst-proof hose.

SECTION 2: INSTALLATION
STEP 4: FILL THE MACHINE
WITH WATER AND ADD
DETERGENT
Step 1:
Fill the sump with water until the water indicator light
on the control panel turns off. The sump capacity is 30
gallons.
NOTE: Monitor the water level carefully.
Step 2:
120V Machines: Flip the heater switch to the ON
position.The sump water will reach operating tempera-
ture (160 – 180 °F) in approximately 2-3 hours.
230V and 460V Machines:Turn the heater timer to the
2 Hour position. The sump water will reach operating
temperature (160 – 180 °F) in approximately two hours.
Step 3:
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 4:
Close the lid.
Step 5:
Turn the wash cycle timer to 2 hours for the first time,
and allow the machine to complete the cycle to dissolve
the detergent into the water.
When the machine stops, and after the wash water
reaches operating temperature, it is ready for use. Refer
to Operation for complete operating instructions.

SECTION 3: OPERATION
MAIN OPERATING
COMPONENTS
Familiarize yourself with the main operating
components before operating the machine.
Control Panel
The control panel is located on the front center of the
lid. It contains the heater, wash cycle skimmer and
turntable controls (See Figure Below).
Heater Control
Single Phase Machines:The heater control is a simple
illuminated rocker switch. It controls the heating element
in the sump chamber. The heater control illuminates
when the heating system is on. The heating system is
thermostatically set at the factory to reach a high tem-
perature of 180 °F.The temperature is adjustable using
the thermostat (See Thermostat Section).
NOTES: 120V machines contain an internal power re-
lay that automatically disconnects power to the heater
when the pump turns on; the heater and pump cannot
run simultaneously. After long wash cycles it may be
necessary to let the machine sit idle for a period of
time to allow the wash solution to reheat to operating
temperature.
The illuminated heater control is also a low-water indica-
tor; if the wash solution is low, the heater control will not
light up and the heating system will not operate (See
Low Water Shut-off System).
Three Phase Machines:The heater control is a 12-hour
timer switch. It controls the heating element in the sump
chamber. The heating system is thermostatically set at
the factory to reach a high temperature of 180°f. The
temperature is adjustable using the thermostat (See
Thermostat).
Wash Cycle Control
The wash cycle control is a 15 minute (120V - no hold)
or 60-minute (220V -with hold) 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 (220V
Only), the pump and turntable run continuously until
manually shut off.
Turntable Switch
The turntable switch is a simple rocker switch that
enables you to disconnect power to the turntable mo-
tor. 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. For more information refer
to Low Water Shut-off System.
Thermostat
The thermostat is located inside the heating element
and thermostat enclosure.The thermostat is factory-set
to heat the wash solution to a maximum temperature
of 180°f.

SECTION 3: OPERATION
Lid Safety Switch
The lid safety switch is located on the front edge of the
cleaning chamber (See Figure Below). It 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 SAFETY SWITCH
To adjust the safety switch, loosen the two screws to
the left of the lid latch (See Figure Above), move the lid
latch strike plate up or down, then tighten the screws.
When properly adjusted, you should hear a slight “click"
as the lid latch closes and compresses the lid seal and
the lid closure safety switch. There is also a mercury
switch in the control panel that stops the machine from
running in case the lid switch is accidently pushed.
Debris Screen
The debris screen is located just below the wash cham-
ber, and is accessible from the front of the machine (See
Figure Below). The debris screen continuously filters
debris particles from the cleaning solution to ensure
blockage-free spray nozzle operation, and also provides
a safeguard against small parts that might accidentally
be washed through from the cleaning chamber.
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 damage 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 Figures Below).

PARTS WASHER OPERATOR’S MANUAL
SECTION 3: OPERATION
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 typi-
cal operating conditions, add detergent each month af-
ter cleaning the sump chamber. Follow recommended
detergent quantities. Use pH kit to determine the proper
amount of detergent to use. If you need help interpret-
ing 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 evapo-
rates with the water and continously 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 FOR USE
Before you begin to wash parts, it is important that you
properly prepare the machine. Before you begin to use
the machine each day:
• check the water level and add water to the sump
tank if necessary;
• heat the water to operating temperature
• verify that none of the spray nozzles are clogged;
and
• clean the debris screen.
WASHING PARTS
The following procedure assumes that the heater is
on and the sump water is at operating temperature.
To wash parts, perform the following procedure.
WARNING: Hot, high-pressured cleaning solution
could cause serious injury. Always wear rubber
gloves and approved eye protection when loading
and unloading the machine.
Step 1:
Load large, heavy parts directly onto the turntable. Load
small, light parts in the small parts basket, if available.
Make sure none of the parts extend beyond the edge
of the turntable and make sure large, light parts (valve
covers, for example) are secured to the turntable.
NOTE: For optimum cleaning performance, provide a
slight clearance between parts to allow adequate flow
of cleaning solution around and between them.
Step 2:
Close and latch the lid.
NOTE: If you are washing large parts that might impede
turntable rotation, flip the turntable switch OFF.
Step 3:
Set the wash cycle timer to between 1 and 60 minutes
for a timed wash cycle, or set it to Hold for a continu-
ous wash.
Step 4:
When the machine automatically stops (or after you
manually stop the wash cycle), lift the lid and wait a
few moments to allow the parts to cool and dry before
removing them. Most parts flash-dry in seconds.
SHUTTING DOWN THE
MACHINE
To shut down the machine at the end of the day:
• set the wash cycle control to OFF;
• 120V machines: set the heater control to ON
to enable automatic turn-on the following day;
230V and 460V machines: set the heater
control to OFF to prevent unattended heater
operation;
• shut off the water at the supply spigot (if a dedi-
cated water supply is installed); and
• shut off the compressed air at the supply line
(if installed).
WARNING: For 230V and 460V machines, if the
heater is left on unattended the water could evapo-
rate and the oil and grease in the wash chamber
could catch fire.
• For periods of extended shut-down (weekends
and holidays, for example), disconnect power
to the machine.
• If your machine is equipped with an optional
programmable heater timer, periodically verify
the settings to prevent inadvertent unattended
operation.

SECTION 5: MAINTENANCE
MAINTAINING THE MACHINE
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 detergent
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 and grease from the wash solution by
using the oil skimmer.
• For oily or extremely soiled parts, it is recommended
the oil skimmer be operated on a more frequent
basis.
• Examine spray nozzles; clean and align if neces-
sary (See Cleaning and Aligning the Spray
Nozzles).
• Wipe down the exterior of the machine using spray
degreaser and a soft, damp cloth. TO PREVENT
ELECTRICAL COMPONENT FAILURE, DO NOT
SPRAY THE MACHINE WITH WATER.
NOTE: Degreaser spray 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 Clean-
ing out the Sump).
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 figure
below to maintain a proper spray pattern.
NOTE: The spray nozzles are sized and positioned to
optimize the distribution of cleaning solution in the wash
chamber. If you remove the nozzles make sure you
replace them in the correct position on the appropriate
pipe. Spray nozzle specifications are stamped on the
face of each nozzle, as shown.
Cleaning out the Sump
Step 1:
Remove the turntable and the debris screen.To remove
the turntable:
a. Remove the turntable chain guard using a
5/16" wrench or socket (See Figure Below).
b. Disengage the chain from around the perimeter
of the turntable.
NOTE: When you disengage the chain from the turn-
table, be sure to maintain some chain tension to ensure
that the chain does not disengage from the drive pulley.
c. Pull up evenly on the turntable to remove it from
the center pin.
Step 2:
Drain the wash solution from the sump chamber. To
drain the solution either use the sump drain or a small
submersible pump.
Step 3:
Remove sand and other debris from the bottom of the
sump chamber. To remove the debris either flush it out
through the sump drain, or vacuum it out using a wet/dry
Vac. Dispose of the debris in accordance with applicable
local, state, and federal regulations.
