Grounding
Grounding
To maintain grounding continuity when flushing or relieving pressure: hold metal part of the spray gun/dispense valve firmly to the side of a grounded metal pail, then trigger the gun/valve.
The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit. See Grounding illustration, FIG. 3 on page 8.
Tanks: use a ground wire to ground each tank to PR70 base Footswitch: use a ground wire to ground the footswitch to the PR70 base. Spray gun/dispense valve: ground through connection to a properly grounded fluid hose and pump. PR70 Base: use a ground wire and clamp. Loosen the grounding lug locknut and washer. Insert one end of a 1.5 mm2 (12 ga) minimum ground wire into the slot in lug and tighten the locknut securely. Connect the other end of the wire to a true earth ground. Order part 237569 Ground Wire and Clamp.
Air and fluid hoses: use only electrically conductive hoses. Air compressor: follow manufacturer's recommendations. Fluid supply container: follow your local code. Object being sprayed: follow your local code. Solvent pails used when flushing: follow local code. use only conductive metal pails, placed on a grounded surface. Do not place the pail on a non-conductive surface, such as paper or cardboard, which interrupts grounding continuity.

Adjust Dispense Valve Snuff Back
At the end of a shot, a small amount of material is drawn back into the static mixer to prevent extra material from being dispensed. If too much snuff back occurs air will enter the static mixer and can travel up into the dispense valve. If too little snuff back occurs the materials may drip out of the static mixer and affect dispense quantity.
14
313937A
Setup
It is most efficient to adjust the snuff back while material is dispensing but it can also be adjusted when there is no air pressure in the system. 1. If a static mixer is not in place, install one then prime the machine. See Prime the Dispense Head, page 12. 2. Place a waste container under static mixer. 3. Press the start device. 4.
