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 pres- sures 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 ground- ing continuity.
4.Dispensing valve: obtain grounding through con- nection 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 ac- cording 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.
