PARTS WASHER OPERATOR’S MANUAL
SECTION 2: INSTALLATION
BEFORE YOU BEGIN
To prepare to install the machine, choose an
unobstructed, 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 or call a customer service
representative.
When contacting customer service please refer to the
machine identification tag inside the front cover of this
manual for detailed machine specifications.
STEP 1: MAKE 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 com-
ply with the National Electric Code and all applicable
state and local codes.
The machine can only operate on the type of electrical
power indicated on the electrical specifications tag.
Read and understand the electrical specifications tag
to determine the electrical power requirements before
installing the machine.
STEP 2: CONFIGURE THE
24-HOUR, 7-DAY TIMERS
(Optional)
NOTE: This step is required for machines equipped with
an optional 24-hour, 7-day heater timer or a 24-hour,
7-day heater and oil skimmer timer. If your machine
does not have a 24-hour, 7-day timer, skip this step.
The optional 24-hour, 7-day heater timer controls the
heating system. The optional 24-hour, 7-day heater
and oil skimmer timer controls the heating system and
the oil skimmer.
The parts washer requires approximately 1 to 2 hours
to heat the wash solution to operating temperature, and
the oil skimmer requires up to 15 minutes to effectively
remove oil from the wash solution. Using either timer,
you can schedule the heating system to turn on several
hours before you begin to use the machine each day.
In addition, the optional 24- hour, 7-day heater and oil
skimmer timer allows you to schedule the oil skimmer
to operate while the machine sits idle.
The timer is located below the electrical panel inside the
main electrical enclosure. To configure the timer, refer
to the instruction label inside the timer door.
STEP 3: CONNECT A
COMPRESSED-AIR LINE AND
ACCESSORIES
NOTE: This step is required for machines equipped with
the Deluxe Edition option package. If your machine is
not equipped with the Deluxe Edition option package,
skip the following procedure.
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 valve
(See Figure Below), then install a fitting to accommo-
date a connection to your compressed-air supply.
Step 3:
Connect the shop compressed-air line to the machine.
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. Manu-
facturer 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 4:
Connect the hose from the power brush to the air flow
valve.
Step 5:
Hang the power brush on the bracket mounted along
the right side of the machine.

STEP 4: CONNECT A
WATER LINE
NOTE: This step is required for machines equipped with
the optional automatic water fill feature. If your machine
does not have this option, skip this step.
The optional automatic water fill feature automatically
maintains the correct water level in the sump. The
feature requires that you connect the machine to a
dedicated water supply line.
To connect the machine to a water supply line, attach
a suitable burst-proof hose to the hose connection on
the rear of the machine below the oil skimmer assembly
(See Figure Below), then connect the hose to a nearby
water spigot.
NOTE: 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.
SECTION 2: INSTALLATION
STEP 5: FILL THE MACHINE
WITH WATER AND ADD
DETERGENT
Step 1:
Fill the sump with water. If your machine is equipped
with the automatic water fill feature, simply open the
water inlet valve; if not, add water through the wash
chamber. The sump capacity is 50 gallons.
Step 2:
When the sump is full and the low water light has gone
out, shut off the water. If your machine is equipped with
the automatic water fill feature the water will shut off
automatically when the sump is full.
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 sump tank when the pump is off.
Step 3:
Turn the heater timer to the 2-hour position. The sump
water will reach operating temperature (160–180°F) in
approximately 1-2 hours.
NOTE: To avoid waiting for the sump water to heat to
operating temperature every day, manufacturer recom-
mends a 24-hour, 7-day heater timer. With a 24-hour,
7-day timer you can set the heating system to turn on
several hours before you begin to use the machine each
day. For more information about 24-hour, 7-day timers
refer to 24-hour, 7-day Timers.
Step 4:
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 5:
Close and latch the door.

SECTION 3: OPERATION
Oil Skimmer
The oil skimmer is located on the right rear corner of the
machine (See Figure Below). It automatically removes
oil from the wash solution to prolong its useful life. Re-
fer to Using the Oil Skimmer for detailed operating
instructions.
Water Level
Under typical operating conditions the machine loses
3 to 5 gallons of water per day to evaporation.
It is important that you monitor and maintain the water
level daily to minimize the risk of burning out the heating
element or ruining the pump.
NOTE: Water evaporates from the sump chamber,
but the detergent does not. It is not necessary to add
detergent each time you add water. Only add deter-
gent after you clean the sump chamber each month,
or if you notice specific low-detergent indicators
(See Detergents and Additives).
Automatic Water Fill (Optional)
The optional automatic water fill system automatically
maintains a proper water level in the sump.
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 figure below describes the
operation of the automatic water fill system.
Low Water Shut-off
The low water shut-off system shuts down the machine
if the wash solution in the sump chamber drops below a
safe level. The system uses two proximity switches and
a float rod mounted near the rear of the sump chamber
to monitor the water level.
If the wash solution drops below the lower proximity
switch, the low water indicator light on the control panel
turns on and the system disconnects power to machine.
To reset the system, add water to the sump until the
low water indicator light turns off.

SECTION 3: OPERATION
NOTE: If your machine is equipped with the optional
automatic water fill feature, the sump will automatically
fill when the water level drops below the lower low water
proximity switch.
Filtration and Sump Sweep Systems
(Optional)
The optional filtration and sump sweep systems reduce
or eliminate the need to manually clean out the sump.
The filtration system continuously filters solid particles
from the wash solution, and you can use the sump
sweep system to periodically remove waste build up
from the bottom of the sump chamber.
Filtration System (Optional)
The filtration system uses a filter canister with a nylon
or polyester felt filter bag to continuously filter solid par-
ticles from the wash solution.The filter system includes
pressure gauges which allow you to monitor the condi-
tion and performance of the filter bag inside the canister.
Under typical operating conditions, the inlet and outlet
pressure gauges read approximately 45 psi. As the filter
bag becomes soiled, the outlet pressure decreases. If
the difference between the inlet and outlet pressure is
15 psi or greater, stop the machine and clean or replace
the filter bag (See Cleaning the Filters).
WARNING: Operating the machine with a clogged
filter system could damage the filter bag. STOPTHE
MACHINE IMMEDIATELY if the difference between
the inlet and outlet pressure is 15 psi or greater.
Sump Sweep System (Optional)
The sump sweep system uses a three-way valve to
divert solution from the wash chamber to a spray bar on
bottom of the sump chamber. The spray bar generates
a high-pressure spray pattern that agitates the sump
solution and suspends solid particles.The solution then
flows through the filtration system which removes the
solid particles (See Cleaning out the Sump).
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 cus-
tomer 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

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 parts into the machine.
Load large, heavy parts directly onto the turntable.
Secure large, light parts (valve covers for example)
to the turntable using suitable rubber tie-downs.
Load small, light parts into the small parts basket
provided with your machine.
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 door.
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), open the door and wait
a few moments to allow the parts to cool and dry before
removing them. Most parts will flash-dry in seconds.
