Grounding

The following are minimum grounding requirements for 
a basic electrostatic system. Your system may include 
other equipment or objects which must be grounded. 
Check your local electrical code for detailed grounding 
instructions. Your system must be connected to a true 
earth ground.

1.

Pump

Use a ground wire and clamp as instructed in your 
pump instruction manual.

2.

Fluid Hoses

Use only grounded hoses with a maximum of 50 
feet (15 m) combined hose length to ensure 
grounding continuity.

3.

Spray gun, manifold, or dispensing valve

Obtain grounding through connection to a properly 
grounded connection to a properly grounded fluid 
hose and sprayer.

4.

Object being sprayed

According to local code.

5.

Supply Containers

According to local code.

6.

All solvent pails 

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. All solvent pails used when flushing must 
be grounded according to local code. 

NOTE: 

To maintain grounding continuity when flushing 

or relieving pressure, always hold a metal part of the 
gun firmly to the side of a grounded metal pail, then trig-
ger the gun.

Connect a ground wire from a true earth ground to the 
mix manifold or the mix manifold mounting surface if 
there is electrical continuity between it and the mix man-
ifold.

Follow the specific grounding instructions in the M2K 
Spray Package manual 333309. The system may have 
special grounding requirements for the mix manifold.

A ground wire and clamp, part no. 223547, is available 
from Graco.

Flush Before Using Equipment

The equipment was tested with lightweight oil, which is 
left in the fluid passages to protect parts. To avoid con-
taminating your fluid with oil, flush the equipment with a 
compatible solvent before using the equipment. See 

Flushing

, page 7.

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.
