Systems With Explosion-Proof Heaters; Motor Position - Graco XP-H Series Operation, Repair, And Parts

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