Overview

Overview

Usage

XM plural-component sprayers can mix and spray most
two-component epoxy and urethane protective coatings.
When using quick-setting materials (less than 10 minute
pot life) a remote mix manifold must be used.
The XM sprayer operates using compressed air
pressure. XM plural-component sprayers are operated
via the user interface, air controls, and fluid controls.
The models with the alternator control box option
feature an intrinsically safe alternator powered by a
compressed air-fed turbine as a power supply. The
alternator module working pressure must be set to 18
+/- 1 psi (12.6 +/- 10 kPa, 1.26 +/- 0.07 bar).

Location

XM OEM sprayers are not approved for use in
hazardous locations.

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 for the electric current.
NOTE: If wall power is used, ground the electrical
connection properly according to local codes.
Control box: Connect the control box ground wire (73)
to a true earth ground.
Pump: Connect the ground cable (15) provided on the
back of the control box ground nut to the ground screw
(G). Verify that the ground screw (G) is attached and
tightened securely to the air motor.

Air and fluid hoses: Use only electrically conductive
hoses with a maximum of 500 ft (152 m) combined hose
length to ensure grounding continuity. Check electrical
resistance of hose regularly. If total resistance to ground
exceeds 29 megaohms, replace hose immediately.
Spray gun: Ground through connection to a properly
grounded fluid hose and pump.
Solvent pails: Follow your local code. Use only
conductive metal pails, placed on a grounded surface.
Do not place the pail on a non-conductive surface, such
as paper or cardboard, which interrupts grounding
continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold the metal part of the spray gun
firmly to the side of a grounded metal pail, then trigger
the gun.
Object being sprayed: Follow your local code.
Fluid supply container: Follow your local code.
Air compressor: Follow manufacturer's
recommendations.
