Installation
4313291D
Installation
Grounding
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
Pump: connect the ground wire (A) firmly to a metal
part of the tank such as the swivel (B) at the base of the
regulator. Connect the other end of the wire to a true
earth ground. See FIG. 1. Order Part No. 237569
Ground Wire and Clamp.
Air compressor: follow manufacturer’s
recommendations.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive sur-
face, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray gun
firmly to the side of a grounded metal pail, then trigger
the gun.
WARNINGWARNINGWARNING
WARNING
PRESSURIZED ALUMINUM PARTS HAZARD
Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids
containing such solvents in pressurized aluminum equipment. Such use can cause serious chemical
reaction and equipment rupture, and result in death, serious injury, and property damage.
PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when operating, servicing, or when in the operating
area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic
fumes, burns, and hearing loss. This equipment includes but is not limited to:

Setup
• Single-Regulated Tank (Model 24A555): When
the air pressure to the tank and the spray gun atom-
izing air are controlled by one regulator, regulated
air controls the tank pressure and unregulated air is
supplied to the spray gun. See FIG. 3.
• Dual-Regulated Tank (Model 24A557): For sepa-
rate control of the atomizing air, a separate atomiz-
ing air regulator for the tank is supplied. See FIG. 4.
1. Install an air filter upstream from the regulator to
remove dirt and moisture from your air supply.
2. Screw the handle (B) and the nut (C) onto the cover,
and tighten them securely.
3. Screw the riser tube (E) into the pipe fitting on the
bottom side of the tank cover. See FIG. 2.
4. Screw the swivel union (2) into the port marked AIR
on the tank cover.
5. Assemble the air regulator (9). See page 8 for
Model 24A555, single-regulated tank. See page 9
for Model 24A557, dual-regulated tank.
6. Screw the assembled regulator into the swivel
union (2).
7. Connect an air supply hose to the 1/4 npt air inlet fit-
ting (9c-1). Connect the gun’s air atomizing hose to
fitting (9c-2). See FIG. 3 for single-regulated tanks.
See FIG. 4 for dual-regulated tanks.
8. Connect the gun’s fluid hose to the adapter (D) at
the point marked PAINT. See FIG. 2.
9. Connect the air atomizing and fluid hoses to the
gun. See FIG. 2.
NOTICE
Use thread sealant on all male threads.

Operation
Pressure Relief Procedure
1. Shut off the air supply to the tank.
2. Lift the pressure relief valve ring (1b) to open it. See
FIG. 5.
3. When no air is escaping through the valve, unscrew
the wing nuts and remove the tank cover (H).
4. Leave the pressure relief valve open until you have
reinstalled the cover.
Fill the Tank
1. Follow the manufacturer’s recommendations to pre-
pare the paint or other coating. Strain the paint to
remove particles or sediment that could clog the
spray gun and hose.
2. Follow Pressure Relief Procedure (above).
3. Unscrew the wing nuts and remove the cover (H).
4. Fill the tank with the paint. Leave at least 2 in.
(51 mm) between the paint level and the tank cover.
A one gallon paint can may be placed inside the
pressure tank.
5. Install the tank cover and evenly hand tighten the
wing nuts. Overtightening the nuts may cause the
gasket (1c) to squeeze out. The gasket is needed to
properly seal the cover and tank.
Adjust the Air Regulators
Turn the air regulator T handle counterclockwise all the
way to off. Turn on the master air supply. Adjust the air
regulators to the required pressure. Always use the low-
est pressure necessary to obtain the desired results.
Lower pressures help reduce spray tip wear.
Vertical and Horizontal Reach
Do not operate the spray gun more than 10 ft (3.1 m)
above the paint tank. Longer lengths of air and paint
hose may be used between the pressure tank and the
spray gun for greater horizontal working range.
Pressure tanks remain pressurized until pressure is
manually relieved.
NOTICE
Overfilling or tipping the tank causes the paint to
enter the air line and clog the regulator, hose, and
gun. Do not exceed the 2.5 gallon tank capacity.
FIG. 5
To reduce the risk of overpressurizing the tank, which
could result in component rupture and cause serious
injury, never exceed 50 psi (350 kPa, 3.5 bar) maxi-
mum air input pressure to the tank.

Cleaning and Maintenance
313291D 7
Cleaning and Maintenance
1. Follow the Pressure Relief Procedure, page 6.
2. Unscrew the wing nuts and remove the cover (H).
3. Loosen the retaining ring of the spray gun air cap
about three turns.
4. Hold a rag over the air cap and trigger the gun to
force the paint back through the hose and into the
tank.
5. Empty the tank.
6. Pour a compatible solvent into the tank.
7. Replace the cover and tighten the wing nuts evenly
and securely. Keep the wing nuts well greased so
they will screw down freely.
8. Remove the spray gun air cap.
9. Turn on the air supply. Trigger the gun into a waste
container until clean solvent comes from the gun.
10. Empty the solvent and wipe the inside of the tank
and equipment with a solvent-dampened rag.
11. Remove the riser tube (E) and clean it thoroughly.
12. Keep the pressure relief valve (1b) clean and in
working order. The relief valve is preset and locked
to release air automatically if pressure exceeds 50
psi (350 kPa, 3.5 bar).
Technical Data
NOTICE
Be sure the solvent you use is compatible with the
fluid being sprayed and the hose material. If paint comes in contact with the pressure relief
valve, remove and clean the valve thoroughly. If the
valve still doesn’t work properly, replace it with a new
one. Do not try to reset the valve.
