Location

The XP35, XP50, and XP70 systems are approved for use in hazardous locations only if the base model, all accessories, all kits, and all wiring meet local, state, and national codes.

1.Locate the proportioner on a level surface.

2.Position the proportioner for convenient operator access and maintenance, safe routing of air and fluid lines, and easy connection of components and accessories.

3.For permanent mounting, remove wheels and mount the frame to the floor. See Dimensions, page 58.

4.Ensure that the cart brake (L) is in the locked posi- tion.

Grounding

The equipment must be grounded. Grounding reduces the risk of static and electric shock by pro- viding an escape wire for the electrical current due to static build up.

Pump: use ground wire and clamp (supplied). Loosen grounding lug locknut (W) and washer (X). Insert ground wire end (Y) into lug (Z) slot and tighten locknut securely. Connect ground clamp to a true earth ground.

Y

W, X, Z

Solvent Pump: use ground wire and clamp (supplied with solvent pump). Follow instructions in pump manual.

Air and fluid hoses: use only static dissipation type hoses with a maximum of 500 ft (150 m) combined hose length to ensure grounding continuity. Check electrical resistance of hoses regularly. If total resistance to ground exceeds 29 megohms, replace hose immedi- ately.

Air compressor: follow manufacturer’s recommenda- tions.

Spray gun: ground through connection to a properly grounded fluid hose and pump.

Fluid supply container: follow local code.

Object being sprayed: follow 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 nonconductive sur- face, such as paper or cardboard, which interrupts grounding continuity.

To maintain grounding continuity when flushing or relieving pressure: hold metal part of the spray gun

firmly to the side of a grounded metal pail, then trigger the gun.
