LOCATION
Position the unit in a well-ventilated area away from sparks, heat and open flames, at least 6 " from the
back wall.
AIR SUPPLY
• Connect a male air supply adapter (not supplied) into the female Air Inlet on the unit. The male air
supply adapter is 1/4" NPT.
• Connect the female air supply hose to the adapter. The air supply hose must be at least 3/8"
inside diameter. The air supply pressure must be at least 85 PSI and the sup-
ply air must be free from contaminants such as water, dust, rust, tar and
grease. If the air supply is not clean and dry install a moisture filter. The
operation and longevity of the pump and other components depends on
clean dry supply air.
• To prevent damage to the Diaphragm Pump an internal Air Pressure Regulator has been
installed to limit the air pressure to 85 PSI. Do not install a second air pressure regulator or use a
pressure set below 85 PSI.
GROUNDING
• Connect the green ground wire at the back of the unit to a ground in the building.
Note: The pump and metal tube that inserts into each pail are grounded.
SOLVENT SELECTION
The adhesion quality of automotive paint has dramatically improved in recent years. The choice of sol-
vent is critical. Only use good quality solvent that is formulated for your paint and intended for use with
automatic spray guns cleaners. DO NOT USE CHLORINATED SOLVENT.
PAIL SETUP
• Place the suction hose and drain hose in the solvent pail.
• Open the drain valve (vertical position).
• Pour 5 gallons of solvent in the wash tank to drain to the wash pail underneath.

Prevent Solvent From Entering the Air Passage of Spray Gun:
insert the plastic plug into the air tting as in the photo
below . Positive air will ow through the passage way
to the cap during cleaning. If the air passage way has
a a male tting attach the knurled female nut to
prevent sovlent from entering the air passage way.
This tting is located on the chain with the
trigger clamp.
• Close the lid of the spray tank
and turn the "Auto Wash Timer"
clockwise as in photo below
to initiate cleaning. The wash
cycle takes about 60 seconds.
• MANUAL WASH
Open the lid and remove brush from its holder on the back wall of the wash tank.
Step on the foot pedal. A dedicated pump delivers wash solvent through the brush, left photo below.
To control the flow of solvent through the Brush, adjust the Flow Control, also on the front of the
unit, right photo.
•The spray gun can be washed with the brush before or after "Auto" wash.
• Dry the spray gun thoroughly.
REPLACING SOLVENT:
• Replace the solvent when the solvent has lost its cleaning
eectiveness or after approximately 100 cleanings.
• Close the drain valve (horizontal position).
• Remove the pail of used solvent. Dispose of the used solvent
in a manner compliant with the laws in the municipality.
Return the pail to the cabinet and install the suction hose and
drain hose to the pail. Pour 5 gallons of new clean solvent into the
cleaning tank to drain to the pail in the cabinet.

MAINTENANCE
• A removable screen lter is installed at the end of the suction pipe, in the wash pail. See the photos below.
• Once each week, remove the wash pail from the cabinet, remove the suction pipe with the pail, see photos
below, unscrew the metal lter ( see right photo below) and clean the lter in a cup of solvent.
Wash Pail Remove Suction Pipe and Filter Filter
REPLACING SOLVENT
• Replace the solvent when the solvent has lost cleaning eectiveness or after approximately 100 cleanings.
• Close the drain valve, see photo below. Remove the drain hose and suction pipe.
• Pour wash solvent from wash pail into waste drum, rinse out the pail. Replace the pail in the cabinet and
replace place the drain hose and suction hose. Open the drain valve. Pour 5 gallons (19 L) of fresh solvent in
the cleaning tank to ll the pail in the cabinet.

TROUBLESHOOTING PROCEDURES PROCEDURE 1
Blocked Fluid Passage In Diaphagm Pump
If the pump sounds like it is working but liquid does not flow,
clear the fluid passage as follows:
• Remove suction tube from the pail and blow air at 85 PSI
into the INLET Liquid Hose (see diagram). Step on foot
pedal to activate pump. This procedure may have to be
repeated several times. If this procedure does not help,
blow some water into the suction hose using a spray gun,
wait one minute and step on foot pedal to activate pump.
This procedure may have to be repeated several times. If
this procedure does not work, the pump must be replaced.
If you need to replace the pump call the Uni-ram Service
Engineer. The warranty on the diaphragm pump is two
years from date of purchase.
This procedure will also clear a blockage in the fluid line for the brush. Follow the same procedure to
clear a blockage in the automatic nozzle except turn the timer instead of stepping on the foot pedal.
PROCEDURE 2
Blocked Air Passage In Diaphragm Pump
If there is a steady hissing sound and the pump is not
cycling, the spool valve has stalled due to a blocked air pas-
sage. Follow the procedure below to clear the blockage.
• Connect a blow gun to an 85 PSI source. Locate the
blue hose that extends from the air exhaust port of
the diaphragm pump. Use a blow gun to blow air into
the open end of this hose. Turn timer. If the procedure
is successful, the pump will start working. The proce-
dure may have to be repeated several times. If this
procedure does not work, replace the pump.
• Cause: Contaminants in the air supply (water, oil,
solid particles etc)
• Preventative Action: If necessary, install an Airline (Moisture) Filter.
PROCEDURE 3
Blocked Passage in Air Line
The components in the air line are the diaphragm pump, air valve, foot pedal, 3-way ball valve
and regulator. See the Flow Diagram and the section: Replacement Parts.
To troubleshoot a component:
1) Disconnect the air line to the component using the quick disconnect.
2) Step on foot pedal and check for presence of positive air pressure in the air line. If there is ample
positive air pressure, replace the component.
If air pressure is absent, there is a faulty component upstream. Reconnect the air line and check the
operation of the next component upstream by following steps 1 and 2 above.
