Graco 225 important safety instructions Mounting the Pump, Grounding

Mounting the Pump

WARNING

Mount the pump securely so that it cannot move dur- ing operation. Failure to do so could result in personal injury or equipment damage.

•Select a location that allows the operator easy access to the pump and air controls, sufficient room to change supply containers, and a secure mount- ing platform.

•If you are mounting the pump directly on the supply container, be sure it is positioned so the pump’s intake tube 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.

To prevent damage to the pump, remove sedi- ment from the bottom of the container before installing a pump in an existing container.

Grounding

Proper grounding is essential to maintaining a safe sys- tem.

To reduce the risk of static sparking, ground the pump. Check local electrical codes for detailed grounding instructions for your area and equipment type. Be sure the following equipment is properly grounded:

•Pump: See FIG. 2

•Air and Fluid hoses: Use only electrically conductive hoses.

•Air compressor: Follow manufacturer’s recommen- dations.

•Dispensing valve: Obtain grounding through con- nection to a properly grounded fluid hose and pump.

•Fluid supply container: Follow your local code.

•Object being lubricated: Follow your local code.

•Any pails used when flushing: Use only metal, grounded pails when flushing. Make firm metal-to-metal contact between a metal part of the dispensing valve and the pail. Use the lowest possi- ble pressure.

Installation

•To maintain grounding continuity when flushing or relieving pressure, always hold a metal part of the dispensing valve firmly to the side of a metal pail and then open the dispensing valve.

To maintain grounding continuity when flushing or reliev- ing pressure, always hold a metal part of the valve firmly to the side of a grounded metal pail, then trigger the valve.

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. 2. To order a ground wire and clamp order Part No. 222011.
