AIR SUPPLY
• Connect a male 1/4" NPT air supply plug (not supplied) into the female Air Inlet on the unit.
• Connect the female air supply hose to the plug. The air supply hose must be at least 3/8" inside diameter.
The air supply pressure must be at least 85 PSI and the supply 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 the presence of clean and
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 using the ring terminal on
the ground wire.
Note: The pump and metal tube that inserts into each pail are grounded.
INSTALLATION OF VENT AND HOOD SUPPORT

MANUAL - 1684 SPRAY GUN CLEANER REVISED 2019-06
• The vent kit is located in a box in the cabinet.
Locate the hole for the vent on the underside
of the top of the cabinet. See photo to the
right and below, left.
• Push the vent through the hole and install one
screw in the front screw hole. Hold the
vent in place if necessary and reach on top
of the cabinet to install a wing nut onto the
screw. See the photo in the lower left below.
• Install the 3 other screws and wing nuts
in a similar way. To not tighten the wing nuts.
• Connect blue airline located near the vent on the inside of
the sink to the vent. See photo on right.
• Place the Hood Support between the wing nut
and the top of the cabinet. Tighten the 4 wing
nuts. See the photo below right.
OPTION - CONVERTING THE TANK TO A 2 SPRAY GUN CLEANER
• The post of the Rotating Jets can be replaced with a
nozzle from the accesssory kit, part 110-356 (see
drawings of replacement parts) to convert the tank to
a 2 spray gun cleaner.
• To remove the post of the Rotating Jets you will need 2
spanners. One spanner grips the nut (not seen) below
the post of the Rotating Jets and one spanner
grips the nut at the bottom of the post of the
Rotating Jets. Hold the spanner on the nut below
the post of the Rotating Jets steady and turn
anti-clockwise the nut of the post of the Rotating Jets.
• Install the Nozzle Extension, 110-356.

PAIL SETUP
• Remove the cabinet door.
• Heritage-Crystal Clean provides a wash pail and a clean pail. The wash pail has 3 gallons of solvent and the
clean rinse pail has 5 gallons of solvent. Place the wash pail on the left side in front of the cabinet and the
rinse pail on the right side.
• Close the drain valve (horizontal position) to stop solvent dripping from the cleaning tank. See photo of the
Drain Valve below.
• Insert the black convoluted drain hose into the back hole of the wash pail. See photo below. Insert the suction
hose and brush hose into the front hole of the wash pail. See the photo of the unit below. Open the drain
valve (veritcal position) located inside the cabinet. See photo below. Place the wash pail in the left side of the
cabinet.
• The rinse pump is the stainless steel tube located in the bottom of the cabinet. Insert the rinse pump and tube
for the spigot into the opening and place the 5 gallon pail of solvent in the cabinet on the right side.
Check to ensure the Drain Valve is in the open position (handle in vertical position)
The stainless steel inlet filter is located at the end of the
suction hose and prevents debris from reaching the pump
and wash tank. See the photo of the filter at right. Clean the
filter monthly. The procedure to clean the filter is
described in the Section, MONTHLY MAINTENANCE.

PREVENT SOLVENT FROM ENTERING THE AIR PASSAGE OF THE SPRAY GUN
• Insert the plastic plug into the air fitting as in the photo at right.
• Positive air will flow through the passage way during cleaning.
• If you disconnect the air plug from the spray gun attach
the knurled nut to the air passageway of the spray gun. The nurled nut
is located on the chain with the trigger lock spring.
Cleaning Cycle:
• Close the lid of the spray tank and turn the "Auto Wash Timer" clockwise. See photo below. The maximum time
is 5 minutes.
• Push and hold the "Air Rinse" button for about 5 seconds to evacuate the wash liquid and air rinse the spray
guns. See photo below.
• Press and hold the "Clean Rinse" button for about 5 seconds to send 100 cc of clean liquid through the jets to
rinse the spray guns. See photo below.
• Press the air rinse button for 5 seconds.
MANUAL WASH
• Use the brush to manually clean the outside of the spray gun. See the photo below. The brush is located on
the wall of the right side of the tank. Step on the foot pedal to activate water flow from the wash pail. See the
photo on page 3 for the location of the brush and foot pedal.
• Rinse the spray gun or pressure pot using the spigot. Step on the foot pedal to activate solvent flow from the
clean solvent pail. See the photo on page 3 for the location of the nozzle and foot pedal.

REPLACING SOLVENT
1) Remove the clean pail (right side) from the cabinet and then remove the rinse pump and tube for the spigot from
the clean pail.
2) Close the drain valve (left photo below). Remove the drain hose and suction pipes from the wash pail and take the
pail out of the cabinet. See middle and left photo below.
3) Replace the pail of wash solvent with a fresh pail of wash solvent. The replacement pail contains 3 gallons of
clean wash solvent. Top up the clean water pail to 5 gallons. Return the pails to the cabinet.
4) Open the drain ball valve (verticle position)

TROUBLESHOOTING PROCEDURES
PROCEDURE 1
The 5" diaphragm pump, UDP5TA, powers the wash tank and a UDP2TAB pump powers the brush and spigot.
5" Diaphragm Pump, UDP5TA for Wash Tank:
• If the pump sounds like it is working but liquid does not flow into the wash tank, clear the fluid passage as
follows:
Remove the suction tube from the wash pail and blow air at 85 PSI into the Inlet Solvent Hose (see
diagram below and the Flow Diagram). Turn the timer.
• Repeat these steps several times. If this procedure does not help, disconnect the output hose at the
combination valve. See the flow diagram. Point the end of the output hose into the wash pail. Activate the
pump. If liquid does not flow through the output hose replace the pump. If liquid does flow remove the
blockage in the delivery tubes or jets.

MANUAL - 1684 SPRAY GUN CLEANER REVISED 2019-06
UDP2TA:
• Remove the suction tube from the pail and blow air at 85 PSI
into the INLET Sovent Hose. Step on the foot pedal to activate
the pump for the brush. This procedure may have to be repeated
several times. If this procedure does not help, disconnect the
output hose at the tank wall. See the flow diagram. Point the
end of the output hose into the wash pail. Activate the pump
by steping on the foot pedal. If liquid does not flow through
the output hose replace the pump. If liquid does flow clear the
blockage upstream. The warranty on the diaphragm pump is two
years from date of purchase.
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 passage. Follow the proce-
dure 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 proce-
dure is successful, the pump will start working. The procedure 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 regula-
tor. 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 downstream. Reconnect the air line and check the operation
of the next component upstream by following steps 1 and 2 above.
