Introduction
The spray wash cabinet is designed to clean
parts with a re-circulated detergent and water
solution. The spray wash cabinet cleans with
a combination of temperature, pressure, and
the chemical action of the detergent. The
spray wash cabinet includes an oil skimmer
to prolong the life of the cleaning solution.
The simple controls and operation are
Designed to make the unit easy to operate.

Installation

LOCATION: When choosing a location for
your spray wash cabinet, consider the
following factors:
● The unit will generate steam. Make
sure steam will have no adverse
affects in the area surrounding the
machine.
● Everyday use will result in liquid
Spilling on the floor around the
machine. Consider the use of traction
mats and avoid placing the machine in
high traffic areas.
● Allow access for service and utility
connections.
● Place on a level site.
ELECTRICAL: All electrical requirements
are listed on the identification plate on the
machine. The wiring diagram is inside the
control box. Have your electrician install all
suitable wiring and breaker/disconnect box
necessary. Do not modify power cord
installed on the unit. Once power is installed
have your electrician check motors for
proper rotation but do not turn on heating
elements at this time.
DRAIN CONNECTION: A 2″ drain is
located on the unit.
Make sure you have ready access to a
water source. You will be adding water to
the tank on a daily basis.

Detergent Selection
Upon receiving your spray wash cabinet
inspect for an visible damage from shipping.
If any damage is found, make notation on
your bill of lading and contact your freight
carrier. Follow your freight carrier’s
procedure for handling damage.
If no damage is found, remove all packaging
material from the machine being careful not
to damage the casters on the unit.
Open the door to the unit and unpack all
parts and packing materials inside.

The manufacturer does not warranty this
spray wash cabinet against rust. Rust will
occur if the proper detergent is not used,
if start-up procedure is not followed, or if
your machine is not used on a regular basis.
If not regularly used oil should be used on
the inside of the machine. Rust can also
occur if you use D.I.water for rinsing.

6
A detergent formulated for mild steel
Meeting the following criteria should be met:
● The detergent must have rust
inhibiting agents.
● The detergent should be strong
enough to remove the contaminants,
but not so strong that it attacks the
metal substrate.
● The detergent should only leave an
acceptable amount of residue on the
parts. For new parts, you may need a
detergent that is “free rinsing”.
● For use in spray wash cabinet, the
detergent must be “low foaming”.
The manufacturer offers a line of detergents
developed for use in spray wash cabinets.
For information contact our sales department.
If the parts are critical, it is the customer’s
responsibility to perform any metallurgical tests.

Operation
The controls for the spray cabinet are as
follows:
● CIRCUIT BREAKERS: These are
located on the back of the unit inside the
circuit box. The circuit breakers are
used to power on/off the machine.
● CYCLE TIMER: located on the side of
The cabinet above the door latch. Used
To control the wash cycle.
● OIL SKIMMER: Controlled by a toggle
switch located on junction box behind
the skimmer wheel.
● THERMOSTAT: Located inside the
back cover of the machine. Used to
control the water temperature in the tank.
This should be set to a temperature of
140-160 degrees F.
● SAFETY SWITCH: Prevents pump
From operating when the door is open.

Check water level before starting the
machine. The ideal water depth in the
holding tank is 8″. Water should be even or
just above the filter basket. Water level
should be checked daily.
To heat the solution in the tank, turn the
heat breaker to the on position. Allow at
least 1 hour for the solution to reach 140160 degrees F before first wash cycle.
During daily operation the heating elements
work automatically as needed.
When solution has reached proper
temperature, turn all other breakers to the
on position. Place parts on the wash rack
making sure parts are placed to allow
rotation of the wash rack. Small parts can
be placed in wash baskets provided with the
machine. Close and latch the door and set
the timer to start the wash cycle. Generally,
most wash cycles should be 15-20 minutes.

The oil skimmer is not designed for constant
use. When floating oil is 1/4″to 1/2″ deep, or
When oil starts to impede cleaning, operate
the skimmer. Before operating oil skimmer
place a collection container at the oil
Skimmer to collect material skimmed.
Follow all regulations for disposal of
skimmed material.
At the end of daily operations turn off all
power to the spray wash cabinet.

Initial Start-Up Procedure

13. Run the spray wash cabinet for at
least 1-hour of wash cycles for the
next two days.
14. Adjust oil skimmer flanges to make
light contact with the skimmer wheel.
Use care to not put excess strain on
the oil skimmer motor.
Your machine is now ready for daily
operation. The more wash cycles you run,
the more the cabinet is coated with rust
inhibitors.
If you have any questions about start up or
installation of your machine contact your
provider.

For first time use , follow the following
procedure:
1. Make sure electrical power to the
Machine is off.
2. Verify that your electrician has done
all necessary work.
3. Verify heat and wash breakers are
In the off position.
4. Fill the tank with water. Add water
until the water level is just above the
removable filter basket.
5. Verify thermostat is set between
140-160 degrees F.
6. Turn on electrical power to the
machine.
7. Turn the heater breaker to the on
position.
8. When the water temperature has
reached the proper temperature,
add detergent following the
detergent manufacture’s directions.
Pour the detergent directly into the
Filter basket.
9. Close and latch the door. Turn all
other breakers to the on position.
Set the wash timer to run a 15minute wash cycle.
10. During the initial wash cycle, walk
around the machine and check for
leaks.
11. At the end of wash cycle, open
the door.
12. If water was leaking around the door,
Adjust the direction of the spray
nozzles to spray away from the door.

Solution Disposal
Protect your environment an protect your
business from fines by handling your
cleaning solution according to federal, state,
and local codes. According to federal
regulations, which states have to adopt as
minimum standards, the dirty cleaning
solution in a spray wash cabinet is generally
not “hazardous waste”.
The two characteristics that you have to be
most concerned about are corrosivity and
Ep toxicity. Ask your detergent supplier is
the PH of your solution is greater than 12.5
and if so, how it can be neutralized. To
check for Ep toxicity, you would need to
have a sample tested by a laboratory.
Assuming that your solution is not
hazardous, or that with minor treatment (e.g.
adding acid) the solution can be made nonhazardours, the EPA does not require special
storage, documentation, transportation, and
processing. Since your solution will have oils,
however, you will probably not be able to
dump the solution in the sewage line (call
your sewage treatment facility) and you
certainly can’t dump the solution on the
ground or in a storm drain. You can
separate the oil and solid contaminants from
the solution so that the cleaning solution can
last for an indefinite period.

Maintenance
Do not allow the sludge accumulation in the
tank to exceed a 1″ depth. Otherwise, the
sludge build-up could damage the heating
element(s) and pump. Depending on the
application, some businesses have to clean
out the sludge weekly, while others can go
months before cleaning out the tank. Since
you can’t see the sludge, clean out the tank
within the first week of operation and
develop an appropriate clean out schedule.
The following procedure should be followed
for sludge removal:
● Disconnect all power to the machine
or make sure all breakers are in the
off position.
● Remove the wash rack and filter
basket from the machine.
● Using the drain, remove solution from
the tank. You can save the solution
for reuse.
● Scrape out the sludge through the
filter basket opening being careful to
not hit the heating element.
● Close the drain and install the filter
Basket and wash rack.
● Fill tank with solution to proper level.
If spray nozzles become clogged you may
need to flush the spray tubes. Remove all
pipe caps and bottom spray nozzles and run
a maximum of 60 second wash cycle.

Follow daily and monthly maintenance
guidelines included in this manual.
