A bleed-type master air valve (A) is required in your
system to relieve the air trapped between the valve
and the pump after the pump is shut off. Trapped air
can cause the pump to cycle unexpectedly, resulting
in possible serious injury, including amputation.
Note
To ensure the maximum pump performance
and safety, be sure that all the accessories
used are properly sized to meet your system
requirements and the pressure limits of the
pump. Use only genuine Graco parts and
accessories.
In the air line, install an air filter (F) to remove
harmful dirt and moisture from the compressed air
supply. Install an air line lubricator (H) downstream
from the air filter, the air regulator (B) and the
bleed-type master air valve (A). A lubricator will
provide automatic lubrication to the air motor.

Connect an electrically conductive air supply
hose to the 3/4” npt(f) port of the air regulator (B).
Open the bleed-type master air valve (A) and,
using the pressure gauge, set the air regulator
(B) to the desired pressure.

Grounding
Grounding
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes
to ignite or explode. Grounding provides an escape
wire for the electric current.
Pump:
See XL Air Motor instruction manual for
complete grounding instructions.
Air and fluid hoses:
Use only electrically conductive
hoses with a maximum of 500 feet (150 m) combined
hose length to ensure grounding continuity.
Air compressor:
Follow the air compressor
manufacturer’s recommendations.
Spray gun or dispensing valve:
Obtain grounding
through connection to a properly grounded fluid hose
and pump.
Fluid supply container:
follow local code.
Object being sprayed:
follow local code.
All solvent pails used when flushing:
According to
local code. Use only conductive metal pails which are
conductive, placed on a grounded surface. Do not
place the pail on a non-conductive surface, such as
paper or cardboard, which interrupts the grounding
continuity.
To maintain grounding continuity when flushing or
relieving pressure:
Hold a metal part of the gun or
dispensing valve firmly to the side of a grounded
metal pail, then trigger the gun.
