Setup

Grounding

The equipment must be grounded to reduce the risk of static sparking and electric shock. Electric or static sparking can cause fumes to ignite or explode. Improper grounding can cause electric shock. Grounding provides an escape wire for the electric current

FRP Proportioner Grounding

NOTE: All proportioners come with one grounding clamp to ground the proportioner to a true earth ground. All accessories for internal mix systems come with a second grounding clamp to ground the solvent flush system to the cart.

1.Verify that the ground screw is attached and tight- ened securely to the air motor. Connect the other end of the ground wire to a true earth ground.

General Grounding Guidelines

Pump: use ground wire and clamp (supplied). Connect ground clamp to a true earth ground.

Air and fluid hoses: use only electrically conductive hoses.

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.

2.For internal mix systems only, ground the solvent flush system.

a.For solvent flush diaphragm pumps only, con- nect one end of the second grounding clamp to the solvent pump grounding strip. See the dia- phragm pump manual listed on page 3 for grounding details.

b.Connect the other end of the grounding clamp to the cart.

3.Use an ohmmeter to verify all components are grounded to the earth ground.

4.If wall power is used to power the heater, ground electrical connection according to local codes.

5.For cart proportioners: Connect the other end of the

second supplied grounding clamp to the cart.

For wall proportioners: Connect the other end of the second supplied grounding clamp to a true earth ground.
