Wire Sprayers With Explosion-Proof Heaters; Connect Air Supply - Graco XM Series Operation

Setup
Wire Sprayers with
Explosion-Proof Heaters
(Hazardous location sprayers only)
If your sprayer is rated for hazardous areas, and you
have explosion-proof heaters, a qualified electrician
must connect the heater wiring. Ensure wiring and
installation comply with local electrical codes for
hazardous areas.
Improperly installed or connected equipment will create
a hazardous condition and cause fire, explosion, or
electric shock. Follow local regulations.
When explosion-proof heaters are used, ensure wiring,
wiring connections, switches, and electrical distribution
panel all meet flame-proof (explosion-proof)
requirements.
Refer to Viscon HP heater manual 309524 for electrical
connection instructions and guidelines in hazardous
locations.

Connect air supply line to 3/4 npt(f) air filter inlet.
Use a 3/4 in. (19.1 mm) ID minimum air hose.
E
Air supply requirement: 150 psi (1.0 MPa, 10.3 bar)
maximum; 50 psi (0.35 MPa, 3.5 bar) minimum (while
running).
Flow volume required: 70 scfm (1.96 m
3
250 scfm (7.0 m /min) maximum. Available fluid
pressure and flow rate are directly related to available
air volume. See Pump Performance Charts, page 86.
General flow volume guidelines:
- 70 scfm (1.96 m

If your sprayer is for use in hazardous areas, the control
box is powered by an air-driven alternator.
Dosing valves are operated by air. The sprayer will not
operate correctly if the inlet air gauge drops below 50
psi (0.35 MPa, 3.5 bar) while spraying.
