Grounding

WARNING

FIRE AND EXPLOSION HAZARD This pump must be grounded. Before operating the pump, ground the system as explained below. Also, read the sec- tion FIRE AND EXPLOSION HAZARD, on page 4.

Polypropylene and PVDF are not conductive. Attaching the ground wire to the grounding lug will ground only the air motor. When pumping conduc- tive flammable fluids, always ground the entire fluid system by making sure the fluid has an electri- cal path to a true earth ground. See Fig. 1.

Never use a polypropylene or a PVDF pump with non-conductive flammable fluids as specified by your local fire protection code.

US Code (NFPA 77 Static Electricity) recommends a conductivity greater than 50 x 10–12Siemans/me- ter (mhos/meter) over your operating temperature range to reduce the hazard of fire. Consult your fluid supplier to determine the conductivity or resistivity of your fluid. The resistivity must be less than 2 x 1012 ohm-centimeters.

Ground all of this equipment:

DAir Motor: Connect a ground wire and clamp as shown in Fig. 1. Loosen the grounding screw (W).

Insert one end of a 12 ga (1.5 mm@) minimum ground wire (Y) behind the grounding screw and tighten the screw securely. Connect the clamp end of the ground wire to a true earth ground. Order Part No. 237569 Ground Wire and Clamp.

NOTE: When pumping conductive flammable fluids with a polypropylene or a PVDF pump, always ground the entire fluid system. See the WARNING on page 6.

DAir and fluid hoses: Use only electrically conductive hoses.

DAir compressor: Follow the manufacturer’s recom- mendations.

DAll solvent pails used when flushing: Follow the local code. Use only metal pails, which are conduc- tive. Do not place the pail on a non-conductive surface, such as paper or cardboard, which inter- rupts the grounding continuity.

DFluid supply container: Follow the local code.

This feature ensures minimal downtime, making it especially valuable on job sites where time efficiency is crucial.

The sprayer is also equipped with a powerful electric motor that delivers a consistent pressure of up to 3000 PSI. This high pressure not only facilitates a fine atomization of paint but also enables users to work with a variety of coatings, including thicker materials like latex, stains, and sealers. As a result, users can achieve professional-grade finishes on a range of surfaces, from buildings to fences.

Another significant characteristic of the Graco 308550ZAC is its adjustable pressure control. This feature allows operators to fine-tune the pressure according to the specific paint being used and the project's requirements. This flexibility translates to improved control over the spraying process, minimizing overspray and ensuring precision, particularly when working on detailed areas.

Additionally, the unit comes with a built-in suction hose, which can be submerged directly into paint containers for efficient and seamless painting. This capability makes it easier to use large buckets, reducing the hassle of constantly refilling the sprayer and enhancing productivity.

The Graco 308550ZAC also features a lightweight and portable design, making it easier to transport between job sites. Its robust construction ensures durability, while the ergonomic handle offers comfort during extended use.

In summary, the Graco 308550ZAC is a robust airless paint sprayer that combines advanced technologies and thoughtful design features to meet the needs of both professionals and hobbyists. With its ProXChange system, adjustable pressure control, and high-performance motor, it represents an excellent choice for achieving flawless finishes in various painting applications.
