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 formulated for your paint and intended for use with
automatic spray guns cleaners. DO NOT USE CHLORINATED SOLVENT.
PAIL SETUP FOR AUTOMATIC TANK
• See the photo of the pail arrangement on the next page.
• Move the 5 gallon plastic pail close to the cabinet with the cap at the front. Insert the stainless
steel suction tube into the hole in the cap, insert the drain hose from the manual tank into the right
hole and insert the drain hose from the automatic cleaning tank into the hole at the back of the
pail.
• Place 2 gallons of liquid in the smaller two and one half gallon plastic pail. This pail is for the
manual tank.
• Place the suction hose into the cap of the plastic 2.5 gallon pail and place the pail in the right side
of the cabinet.
• Place the larger pail for the automatic tank into the right side of the cabinet.
• Open the drain valve (see photo on next page).
• Pour 3 gallons of liquid into the automatic cleaning tank to drain into the 5 gallon plastic pail.

Prevent Solvent From Entering the Air Passage of Spray Gun:
insert the plastic plug into the air fi tting of the spray gun
as in the photo below. Positive air will fl ow through the
passage way to the cap during cleaning. If the air passage
way has a a male fi tting attach the knurled female nut to
prevent sovlent from entering the air passage way.
This fi 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.
CLEANING COMPONENTS IN THE MANUAL CLEANING TANK
• Disassemble the spray gun and clean the components in the manual tank using the cleaning tools.
The cleaning tools include the brushes in the cleaning kit, the Flow-through brush and the flexible
spigot.
• Activate the Flow-through brush by stepping on the foot pedal.
• Activate the flexible spigot by stepping on a second foot pedal.
• Clean liquid flows through the cleaning tools and returns to wash pail.

MAINTENANCE
• A removable screen fi 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 fi lter ( see right photo below) and clean the fi lter in a cup of solvent.
Wash Pail Remove Suction Pipe and Filter Filter
REPLACING SOLVENT
• Replace the solvent when the solvent has lost its cleaning eff ectiveness or after approximately 100 cleanings.
• Close the drain valve, see photo below. Move the large pail out of the cabinet. Remove the drain hoses and
suction pipe.
• Pour wash liquid from the wash pail into a waste drum for later disposal. Rinse out the pail.
• Remove the small pail and add solvent such that the small pail has 2 gallons of liquid.
• Return the small pail with suction tube included to the right side of the cabinet.
• Return the large pail to the left side of the cabinet with one suction hose and 2 drain hoses inserted.
• Close the drain valve. Pour 3 gallons (12 L) of fresh solvent in the cleaning tank to fi ll the large 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.
