Installation

NOTE: Letters in parenthesis used in this section refer
to the callouts in Component Identification on page 8.

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. Follow the grounding instruc-
tions described in the manual for the feed system you
are using.

described on page 13.

Connecting to Other Equipment

If the original equipment does not require the use of an
unheated whip hose or isolation hose, the Auto P2 can
be directly installed on to the material hose.
1. When replacing an existing gun, remove all of the
hoses and fittings from the original gun.
2. Remove the swivel fitting connections (A,B) from the
material shutoff valves (E,F) on the P2 as shown
below. The valve connections are 1/8 in. NPT
female.

3. Remove the air hose from the supply air switch (D).
The supply air switch fitting is 1/4 in. NPSM.
4. Install the fittings from the original gun into the
material shutoff valves (E,F) on the P2.
NOTE: You can use a non-permanent thread lock on the
1/8 in. NPT thread to assist as a sealant and keep the
fittings from twisting with gun movement.
5. Install the P2 onto the original hoses.
NOTE: If needed, a swivel fitting, part no. GC2394, is
available for connecting a supply air hose from other
equipment. This part can be purchased separately or as
part of GC1949 Hardware Kit 04-05. See Service and
