CAUTIONS AND WARNINGS
• Always disconnect this machine from power sources before performing maintenance
• Do not smoke or use near open flames, sparks or heat.
• Make sure unit is grounded properly.
FEATURES
This unit combines a Spray Gun Cleaner for solvent-based paints on one side (left) and a Spray
Gun Cleaner for water borne paints on the other (right). The left side is equivalent to either a
UG4000 or a UG4500 and the right side to a UM120W. The UG4500 is a UG4000 plus hose
cleaning therefore the UG5500W is equivalent to a UG4500 on the left side.
The left (solvent) side has automatic wash, automatic air flush, automatic solvent rinse, automatic
fume venting with on/off control, manual rinse with Flow-through Brush and a stainless steel tank
and lid. Two spray guns can be cleaned at the same time and the UG5500W can also clean
hoses on the left side. The UM120W side is used to manually clean and rinse one spray gun at a
time. It also has a stainless tank and lid.
The unit comes with a closed-top high density plastic pail for washing already installed on the left
side and and an open-top plastic pail with filters on the right side, also installed. The clean solvent
pail for rinsing is not included and must be supplied by the user.

MANUAL - SPRAY GUN CLEANERS - UG5000W SERIES Revision 2013-02
GROUND WIRES
Connect the external ground wire (right side of cabinet) to an external grounded object.
LEVELING, VENT AND AIR SUPPLY
• Level the machine using the adjustable legs.
• Remove the cover on the "Air Input" (right side of machine) and attach an air supply adapter
(not supplied).
• If necessary, replace the female quick connect on the Whip Air Line with a quick connect that
will fit the male quick connect of your spray gun.
The air supply pressure must be at least 85 PSI and the air must be free from contaminants
such as water, dust, rust, tar, grease etc.
To prevent damage to the Diaphragm Pumps an internal Air Pressure Regulator has been
installed to limit the air pressure to precisely 85 PSI. Do not install a second air pressure regu-
lator or use a pressure set below 85 PSI.
INSTALL BLOW GUN, WASH GUN AND WHIP LINE COUPLER
Remove the Blow Gun, Wash Gun and Whip LIne Coupler from the Acessory Kit bag
(inside the tank) and install on the unit by inserting the appropriate air tubes into the tools
and hanging them on the brackets (Blow Gun and Wash Gun on the right side and Coupler
on the front). Use the labels below the tubes as a guide.
SOLVENT SELECTION
The adhesion quality of automotive paint has dramatically improved in recent years. The
choice of solvent is critical. Only use good quality solvent that is formulated for your paint
and intended for use with automatic spray guns cleaners.
PAIL SETUP (LEFT SIDE, SOLVENT)
• Open the door to the base cabinet
• Combo Ready units (UG5000EW, UG5500EW) come with the pails already installed as shown.
Transfer Hoses are provided with Uni-ram Solvent Recyclers designed for Combo operation
(EP2 models). The UG5000W and UG5500W do not come with a Riser or Overflow Tube. The
Riser and the Overflow Tube are not needed for stand alone operation.
• The left pail has intake tubes for both manual washing and the auto wash cycle plus a black
drain hose. If necessary, open the Drain Valve under the left tank (vertical position) and fill this
pail 2/3 full (3 Gal) by pouring solvent into the tank and letting it drain into the pail. Insert the
Rinse Pump into a pail of clean solvent (not supplied) and place the
pail inside the cabinet.
PAIL SETUP and ADDITION OF UNI-RAM AQUA-KLEEN
(RIGHT SIDE, WATER)
Aqua-Kleen is a state-of-the-art cleaning additive with an enhanced corro-
sion inhibitor for optimal protection of your expensive spray guns.
• Open the door to the base cabinet
• Move the Drain Valve handle to the "closed" (horizontal) position if it
is not already there.

• Move the pail outside the unit. Remove the two filters. Pour a full bottle of Uni-ram Aqua Kleen into
the pail and add tap water until the combined liquid level reaches the bottom of the filter holder.
Replace filter.
• Insert the manual wash suction tube into the pail between the Filter Holder and the wall of the pail.
Move the pail into the cabinet.
OPERATION
LEFT TANK (UG4000, SOLVENT)
PRE - CLEAN
• Disconnect the spray gun from the air hose. Pour paint from the cup (when present) into a 5 gallon
pail (not supplied).
• Rinse cup with solvent and pour into the same
5 gallon pail for later disposal or recycling.
SELECTION OF NOZZLE EXTENSION
780-3530 INSTALLED. HOLES PROVIDE SOLVENT TO CEAN DISPOSABLE CUPADAPTOR.
CANNOT BE USED FOR CONVENTIONAL SYSTEMS.
110-430PPS HOLES PROVIDE SOLVENT TO CLEAN DISPOSABLE CUPADAPTOR. MAY ALSO BE
USED FOR CONVENTIONAL SYSTEMS WITH LARGER OPENINGS IN NECK OF CUP.
110-430 FOR CONVENTIONAL SYSTEMS ONLY WITH SMALLER OPENINGS IN NECK OF CUP.
CLEANING SPRAY GUNS AND CUPS
• Loosen the air cap of the spray gun two full turns.
• Lock the trigger in the open position with the Trigger Lock Spring.
• To prevent liquid from entering the air passgae during automatic
cleaning, insert the white plastic Air Passage Plug into the Spray
Gun's air inlet. If the air inlet has a male threaded connector instead
of a quick connect use the knurled nut attached to the Trigger Clamp
(included).
• Place spray guns facing corner jets. Placement depends on type of spray gun. See pictures
below. Place cups onto the low spray jets and cup holders.
• Close the lid and turn the “TimerControl” knob (left side) clockwise to start cleaning. The cleaning
cycle takes about 60 seconds
• Push and hold the "Rinse Cycle Control" button for about 5 seconds to rinse guns with clean sol-
vent. This will send a pre-set amount of clean solvent (100 cc) through the jets. Wait 30 seconds
for the Rinse Pump to fully recharge before repeating.
• Push and hold the "Air Rinse Control" button for about 3 second to air-rinse the guns.
• The Air Blow Gun can also be used to ait dry the Spary Gun.
The s olvent flow per clean-rinse cycle is limited to 100 cc to minimize consumption. This quantity
is usually sufficient to clean the inside pasages of the spray guns.
USING THE FLOW-THROUGH BRUSH
• To deliver clean solvent through the Brush for rinsing, step on the foot pedal.
• Solvent flow is set at the factory but may be adjusted using the left side "Brush Flow Control".

MANUAL - SPRAY GUN CLEANERS - UG5000W SERIES Revision 2013-02
After cleaning guns, remove the guns and cups from the tank and wipe them dry. Do not store
spray guns in the tank.
RIGHT TANK (UM120W, WATER)
This tank is used to clean spray guns, cups and parts. There are two modes of operation - Manual
Wash and Manual Rinse. NOTE: WATERBORNE PAINT DRIES QUICKLY! TO MINIMIZE
HARDENING OF THE PAINT, BEGIN CLEANING AS SOON AS POSSIBLE AFTER
COMPLETION OF THE PAINT JOB.
PRE - CLEAN WHEN USING A NON DISPOSABLE CUP SYSTEM
Skip this step if you use a disposalble cup system.
• Disconnect the spray gun from the air hose. Pour paint from the cup (when present) into a 5 gallon
pail (not supplied).
CLEAN SPRAY GUNS
• Ensure the the Flocculation Drain Control is in the
closed position so that the used water
accumulates in the reservoir under the
Work Screen.
•If the main air supply is not connected,
connect the whip line to the spray gun.
NOTE: CLEANING WITHOUT A SOURCE
OF AIR COULD ALLOW WATER TO

CLEANING WITH THE WASH GUN
• To clean with the Wash Gun, make sure the Brush Control Lever on the front of the unit is in the
"Close" position (horizontal). Place the Spray Containment Chamber on the Work Screen in the
wash tank. Point the cap of the spay gun into the Spray Containment Chamber as shown in photo.
Place the nozzle of the Wash Gun into the paint channel (where the cup joins the spray gun) as
shown in photo.
• Step on the foot pedal and squeeze the trigger of the spray gun while squeezing the trigger of the
Wash Gun to send a pressurized flow of water through the paint channel. Use the Wash Gun Flow
Control on the side of the cabinet to adjust the flow. The Spray Containment Chamber contains the
spray. Allow water to flow for about 20 seconds to clean the paint channel.
CLEANING WITH THE BRUSH
• If necessary, use the Flow-through Brush to clean the outside of the spray gun. Make sure the
Brush Control Lever on the front of the unit is in the "Open" position (vertical). Step on the foot
pedal to send a pressurized flow of water through the Brush. To control the flow of water through
the Brush, use the Brush Flow Control on the side of the cabinet.
• Use the blow gun to dry the outside of the spray gun.
• To maximize the dying operation, dry the paint channel with the Blow Gun while squeezing the trig-
ger of the spray gun. As a final check for dryness, remove the cap and check it for moisture.
NOTE: THOROUGH DRYING OF THE GUN BOTH INSIDE AND OUT WILL PREVENT
CORROSION.
WATER TREATMENT
When no water remains in the water container under the cleaning tank it is time to treat the dirty
water. There are 2 choices. Use a Uni-ram liquid recycler to recycle the dirty water or flocculate
and filter the dirty water. The flocculation / filtering process is described next.
NOTE: THE
PICTURES
APPLY ONLY
TO THE
SOLVENT SIDE
(LEFT TANK).

MANUAL - SPRAY GUN CLEANERS - UG5000W SERIES Revision 2013-02
• Remove the Work Screen and the side rails. Sprinkle 2 full scoops* of the flocculant, COAG-
KLEEN, evenly over the dirty water. Close the lid and turn the Flocculation Timer fully. When the
Timer is finished wait 2 minutes and turn the timer a second time to the one minute mark.
• Open the Flocculation Drain Valve, using the Control on the front of the unit to drain and filter the
dirty water. Note: As the flocculation proceeds, the water should become clear. The debris
consisting of paint absorbed into the flocculant will collect in the filters. Clean the tank with the
wash gun, wipe off the screen and rails, reinsert them and then close the drain valve. Ensure that
the Air Agitator in the bottom of the tank lies flat.
• Remove the two filters containing the debris and set aside for about 20 minutes to dry. When
the debris is dry, it should have an "oatmeal like" consistency. The debris should be disposed of
according to local environmental regulations.
• If the filtered water is not clean, see the Troubleshooting section.
• The treated water can be reused until it becomes "silky" to the touch and then it should be dis-
posed of according to local environmental regulations. When adding fresh water, refill until the
water reaches the bottom of the filter holder.
• Reuse the filters and replace as required.
* Each scoop = 1 fl oz or 34g of flocculant; 2 kg = about 50-58 scoops.
HOSE CLEANING (UG5500 MODELS ONLY)
• Models with this feature can be used to clean a paint feeder hose up to 100 feet
(30 m) long. Connect the hose to the two fittings on the left side (Solvent Outlet
and Solvent Return). Rotate the "Mode Selector" handle to the horizontal position
and turn the Timer knob clockwise to start the automatic cleaning cycle.
• To air-rinse the hose, push and hold the "Air Rinse Control” button.
• To rinse the hose with clean solvent, push and hold the "Clean Rinse" button for
about 5 seconds. This will use about 100 cc of clean solvent. Wait 30 seconds for
the Rinse Pump to fully recharge before repeating.
• Disconnect the hose.
