Ground System
Ground Air Compressors and Hydraulic
Power Supplies
Ground them according to the manufacturer recommendations.
Ground Air, Fluid, and Hydraulic Hoses
Connected to Pump
Use only electrically conductive hoses with a maximum
of 100 ft (30.5 m) combined hose length to ensure
grounding continuity. Check the electrical resistance of
your air and fluid hoses at least once a week. If the total
resistance to ground exceeds 25 megohms, replace the
hose immediately.
Use a meter that is capable of measuring resistance at this level.
Ground Spray Gun
Ground the spray gun by connecting it to a properly
grounded fluid hose and pump.
The following grounding instructions are minimum
requirements for a system. Your system may include
other equipment or objects that must be grounded.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment. Your
system must be connected to a true earth ground.
Ground Pump
Ground the pump by connecting a ground wire and
clamp between the fluid supply and a true earth ground
as instructed in your separate pump instruction manual.
Ground Fluid Supply Container
Ground the fluid supply container according to local
code.
Ground Object Being Sprayed
Ground the object being sprayed according to local
code.
Ground Solvent Pails
Ground all solvent pails that are used with flushing
according to local code. Use only metal pails, which are
conductive. Do not place the pail on a non-conductive
surface, such as paper or cardboard, which interrupts
the grounding continuity.

Air Line and Accessory Recommendations
1. Install an air pressure regulator on the gun cylinder
air supply line.
A minimum of 70 psi (0.49 MPa, 4.9 bar) air pressure must be supplied to the cylinder for proper
operation. Air pressure opens the valve, a spring
closes the valve. A three-way air valve, which
exhausts cylinder air, is required.
2. Install a bleed-type air shutoff valve on the main air
line. Install an additional bleed-type valve on each
pump air supply line, downstream of the pump air
regulator, to relieve air trapped between this valve
and the pump after the air regulator is shut off.
The bleed-type air shutoff valve is required in your system to relieve air trapped between this valve and the
pump after the air regulator is closed. Trapped air can
cause the pump to cycle unexpectedly, which could
result in serious injury.
Fluid Line and Accessory Recommendations
• A fluid drain valve(s) is required in your system to
assist in relieving fluid pressure in the displacement
pump, hose and gun; triggering the gun to relieve
pressure may not be sufficient.
• A fluid pressure regulator must be installed in the
system if the pump's maximum working pressure
exceeds the gun's maximum fluid working pressure
(see the front cover).
1. Install a fluid filter and drain valve(s) close to the
pump's fluid outlet.
2. Install a fluid pressure regulator to control fluid pressure to the gun.
Some applications require fine-tuned control of fluid
pressure. You can control fluid pressure more accurately with a fluid pressure regulator than by regulating the air pressure to the pump.
3. Install a bleed-type air shutoff valve on the gun air
cylinder supply line, downstream of the air regulator,
to shut off air to the gun cylinder. Connect the air
supply line to the gun cylinder air inlet (C). See Fig.
4.
The cylinder air inlet accepts 1/4 in. (6.3 mm) O.D.
tubing.
3. Install a fluid shutoff valve to shut off the fluid supply
to the gun.
4. For paint spray applications, install an in-line fluid filter, part no. 210500, on the gun fluid inlet (F) to
avoid clogging the spray tip with particles from the
fluid. See Fig. 4.
5. Connect the electrically conductive fluid hose to the
gun fluid inlet (F) or optional in-line filter.
