Installation

NOTE: Reference numbers in parentheses in the text

refer to the numbers in the Parts.

Accessories are available from Graco. Be sure all
accessories are properly sized to withstand the pres­sures in the system.

Mount Valve

Mount the valve on a 0.50 in. (12.7 mm) diameter rod
on a mounting fixture or a dispensing machine. The
bead gun has a clamping set screw (6) for mounting.

Connect the Air Lines

Clean all lines and connections of dirt, burrs, etc. and
blow them out with clean air before connecting them to
the system. Install an air filter in the air supply line to
remove harmful dirt and moisture from the compressed
air.

Grounding

Proper grounding is essential to maintaining a safe
system.

To reduce the risk of static sparking, ground the pump,
bead spray gun, paint spray gun and all other system
equipment.

1. Pump: use a ground wire and clamp.

2. Air compressors and hydraulic power supplies:
follow manufacturer’s recommendations.

3. Air and fluid hoses connected to the pump: use
only grounded hoses with a maximum of 500 feet
(150 m) combined hose length to ensure ground­ing continuity.

4. Dispensing valve: obtain grounding through con­nection to a properly grounded fluid hose, frame
and pump.

5. Fluid supply container: according to local code.

6. All solvent pails used when flushing: ground ac­cording to local code. Use only metal pails, which
are conductive. Do not place the pail on a non­conductive surface, such as paper or cardboard,
which interrupts the grounding continuity.
