FIRE, EXPLOSION, AND ELECTRIC SHOCK HAZARD
Improper grounding, poor air ventilation, open flames, or sparks can cause a hazardous condition and
result in fire or explosion and serious injury.
The PrecisionMix Controller must only be installed and serviced by a qualified electrician.
The PrecisionMix Controller is for use only in non-hazardous locations. The maximum applied relay
voltage shall not exceed +24 volts. Do not operate the controller in hazardous locations, as defined
in Article 500 of the National Electrical Code (USA).
Ground the equipment and the object being sprayed. See Ground the System on page 3–30.
Do not install non-intrinsically safe equipment in a hazardous area.
Provide fresh air ventilation to avoid the buildup of flammable vapors from solvent or the fluid being
sprayed.
Extinguish all the open flames or pilot lights in the spray area.
Keep the spray area free of debris, including solvent, rags, and gasoline.
Do not turn on or off any light switch in the spray area while operating or if fumes are present.
Do not smoke in the spray area.
Do not operate a gasoline engine in the spray area.
If there is any static sparking while using the equipment, stop spraying immediately. Identify and
correct the problem.
Keep liquids away from the electrical components.
Disconnect electrical power at the main switch before servicing the equipment.
The battery inside the PrecisionMix Controller may explode if mishandled. Do not recharge or
disassemble the battery. Do not expose the battery to fire or heat. The battery is intended for use
at normal temperatures, where high temperature cycles are not expected to exceed 212F
(100C).
TOXIC FLUID HAZARD

cal attention.
Do not point the spray gun at anyone or at any part of the body.
Do not put hand or fingers over the spray tip.
Do not stop or deflect fluid leaks with your hand, body, glove, or rag.
Follow the Pressure Relief Procedure on page 4–3 whenever you: are instructed to relieve pres-
sure; stop spraying; clean, check, or service the equipment; or install or clean the spray tip.
Tighten all the fluid connections before operating the equipment.
Check the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately.
