DDispensing valve: Ground through connection to a properly grounded fluid hose and pump.
DObject being dispensed to: Follow your local code.
DSolvent pails used when flushing: Follow your local code. Use only metal pails, which are conductive, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continuity.
DTo maintain grounding continuity when flushing or relieving pressure, hold a metal part of the dispensing gun firmly to the side of a grounded metal pail, then trigger the gun to ground the pump.
To ground the pump, remove the ground screw (Z) and insert through the eye of the ring terminal at end of ground wire (Y). Fasten the ground screw back onto the pump and tighten securely. Connect the other end of the ground wire to a true earth ground. See Fig. 1. To order a ground wire and clamp, order Part No. 222011.
Mounting the Pump
WARNING
Fig. 1
TI1052
Mount the pump securely so that it cannot move around during operation. Failure to do so could result in personal injury or equipment damage.
DAir and fluid hoses: Use only electrically conductive hoses.
DAir compressor: Follow manufacturer’s recommendations.
DSelect a convenient location for the equipment to ensure easy operator access to the pump air controls, sufficient room to change supply containers, and a secure mounting platform.
DIf you are mounting the pump directly on the supply tank, position the pump so its intake valve is no more than 1 in. (25 mm) from the bottom of the container. Mount the pump to the cover or other suitable mounting device.
