Installation
Prepare the Operator
All persons who operate the equipment must be trained
in the safe, efficient operation of all system components
as well as the proper handling of all fluids. All operators
must thoroughly read all instruction manuals, tags, and
labels before operating the equipment.
Prepare the Site
Ensure that you have an adequate compressed air
supply.
Bring a compressed air supply line from the air compressor to the pump location. Be sure all air hoses are
properly sized and pressure-rated for your system. Use
only electrically conductive hoses. The air hose should
have a 3/8 npt(m) thread. A quick disconnect coupling is
recommended.
Keep the site clear of any obstacles or debris that could
interfere with the operator's movement.
Have a grounded, metal pail available for use when
flushing the system.
•The spray gun (H) dispenses the fluid. The gun
houses the spray tip (not shown), which is available
in a wide range of sizes for different spray patterns
and rates of flow. Refer to gun manual for tip installation.
•The red hose (G) provides the gun air supply.
•The blue hose (K) provides the gun fluid supply.
•The suction kit with strainer (J) allows the pump
to draw fluid from a 5 gallon (19 liter) pail.
Inline Fluid Filter Kits
Inline fluid filter kits are available as an accessory in
stainless steel (24F271) or aluminum (24F272), to filter
particles from fluid as it leaves the pump. Kits include a
60 mesh (250 micron) stainless steel element.
Air Line Accessories
Install the following accessories in the order shown in
F
IG
. 2, using adapters as necessary.
Supplied Components
See FIG. 2 on page 9.
• The red-handled bleed-type master air valve (D)
is required in your system to relieve air trapped
between it and the air motor and gun when the valve
is closed. Do not block access to the valve.
• The pump air regulator (F) controls pump speed
and outlet pressure by adjusting the air pressure to
the pump.
• The air pressure relief valve (P) opens automatically to prevent overpressurization of the pump.
• The gun air regulator (E) adjusts the air pressure
to the air-assisted spray gun.
•An air-line filter (C) removes harmful dirt and mois-
ture from the compressed air supply.
• A second bleed-type air shutoff valve (B) isolates
the air line accessories for servicing. Locate
upstream from all other air line accessories.

Installation
Wall Mount Packages
1. Be sure the wall can support the weight of the
pump, bracket, hoses and accessories, as well as
the stress caused during operation.
2. Position the wall bracket at a convenient height. Do
not stretch the suction hose tight; let it hang to assist
fluid flow into the pump. For ease of operation and
service, make sure the pump air inlet, fluid inlet, and
fluid outlet ports are easily accessible.
3. Using the wall bracket as a template, drill mounting
holes in the wall. Hole diameters and wall mounting
dimensions are shown on page 40.
4. Attach the bracket to the wall. Use screws that are
long enough to keep the pump from vibrating during
operation.
NOTE: Be sure the bracket is level.
Grounding
2. Air and fluid hoses: Static electricity may build up
when fluids flow through pumps, hoses, and sprayers. At least one hose must be electrically conductive, with a maximum of 500 ft. (150 m) combined
hose length to ensure grounding continuity. Check
electrical resistance of hoses. If total resistance to
ground exceeds 25 megohms, replace hose immediately.
3. Air compressor: follow manufacturer's recommendations.
4. Spray gun: ground through connection to a properly grounded fluid hose and pump.
5. Fluid supply container: follow your local code.
6. Object being sprayed: follow your local code.
7. Solvent pails used when flushing: follow your
local code. Use only metal pails, which are conductive, placed on a grounded surface. Do not place the
pail on a nonconductive surface, such as paper or
cardboard, which interrupts the grounding continuity.
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.
1. Pump: See FIG. 1. Verify that the ground wire (26)
is attached to the ground screw (23), and the screw
is tightened securely to the adapter plate (10). Use
any of the three threaded holes in the adapter plate.
Connect the other end of the ground wire to a true
earth ground.

8. To maintain grounding continuity when flushing or
relieving pressure, hold a metal part of the spray
gun firmly to the side of a grounded metal pail, then
trigger the gun.
Flush Before Using Equipment
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid contaminating your fluid with oil, flush the equipment with a
compatible solvent before using the equipment. See

Adjust the Atomization
NOTE: Use this procedure with airless and air-assisted
spray guns.
1. Do not turn on atomizing air supply. Fluid pressure
is controlled by the air pressure supplied to the
pump (pump air regulator). Set fluid pressure at low
starting pressure. For low viscosity fluids (less than
25 sec, #2 Zahn cup) with lower percent solids (typically less than 40%), start at 300 psi (2.1 MPa, 21
bar) at pump outlet. For fluids with higher viscosity
or higher solids content, start at 600 psi (4.2 MPa,
42 bar). Refer to the following example.
Example:
Pump Air
Pump
Ratio
15:1 x 20 (0.14, 1.4) = 300 (2.1, 21)
30:1 x 20 (0.14, 1.4) = 600 (4.2, 42)

Install the Spray Tip
Follow Pressure Relief Procedure, page 10. Install the
spray tip and tip guard as explained in your separate
gun manual, supplied.
The fluid output and pattern width depend on the size of
the spray tip, the fluid viscosity, and the fluid pressure.
Use the Spray Tip Selection Chart in your gun instruction manual as a guide for selecting an appropriate
spray tip for your application.
NOTE: The maximum recommended spray tip size is
.019 in. (0.483 mm).
2. Hold gun perpendicular and approximately 12
inches (304 mm) from surface.
3. Move gun first, then pull gun trigger to spray onto
test paper.
4. Increase fluid pressure in 100 psi (0.7 MPa, 7 bar)
increments, just to the point where a further
increase in fluid pressure does not significantly
improve fluid atomization. Refer to the following
example.
Example:
Pump Air Regulator
Pump
Ratio
15:1 x 7 (.05, 0.5) = 100 (0.7, 7.0)
30:1 x 3.3 (0.02, 0.2) = 100 (0.7, 7.0)
