MANUAL - SPRAY GUN CLEANERS - UG7500W REVISED 2023-03
• Clean the paint channel using the Nozzle. Make sure the flow selector lever (blue handle) is in the hori-
zontal position. Then hold the gun up to the Nozzle so that the nozzle fits tightly into the opening of the
paint channel. Step on the right foot pedal to start the flow of water.
AUTO WASH SPRAY GUNS
• Disconnect the Gun from the Coupler.
• Loosen the air cap of the spray gun two full turns. Orient the ears in a horizontal position.
• Lock the trigger in the open position with the Trigger Clamp.
• 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). Positive air pressure
is applied to the air passage during automatic cleaning.
• Place the gun with cup (if present) in the automatic cleaning tank. Close the lid and turn the “Auto Wash
Timer” knob clockwise to start cleaning. Cleaning times are shown on the Timer label. Turn the timer to 5
minutes. If you find that you do not require 5 minutes to clean your spray gun adjust the time accordingly.
• Step on the air rinse pedal for about 3-5 seconds to air-rinse the guns.
DRY WITH AIR
Re-connect the Gun to the Coupler and squeeze the trigger to send air through the paint channel to dry the paint
channel and to check that the gun is clean. Use the Air Blow Gun to dry the outside of the gun.
WATER TREATMENT BY FLOCCULATION (UG7500WF)
When the right pail is empty, the flocculation reservoir will be full of dirty water accumulated during manual
cleaning. This water needs to be treated by flocculation before re-using. IMPORTANT: At this time, the water in
the left pail (used for auto cleaning) should also be treated. If the water on the auto side is left untreated too long,
it will be too dirty for the flocculation process to work properly. The water in the left pail must be transferred into
the flocculation reservoir on the right for flocculation, as discussed below.
FLOCCULATION PROCEDURES (UG7500WF)
RIGHT SIDE (MANUAL CLEANING)
The dirty water from the right pail accumulates in the flocculation resrvoir during use. When the pail is empty
follow these steps to treat the water for re-use:
• 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 fin-
ished wait 2 minutes and turn the timer a second time to the one minute mark. Note: As the flocculation
proceeds, the water should become clear. The debris consisting of paint absorbed into the flocculant will
collect in the filters during the next step.
• Open the drain valve, located under the cleaning tank to drain and filter the dirty water.
• Clean the tank with the wash gun, wipe off the screen and rails and reinsert them.
• Close the drain valve and ensure that the Air Agitator in the bottom of the tank lies flat.
• Leave the two filters containing the debris in place until the next day to allow for them to dry throughly.
When the debris is dry, it should have an "oatmeal like" consistency. The debris can now 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 disposed of
according to local environmental regulations. When adding fresh water, refill until the water reaches the
bottom of the filter holder.
