WARNING
Chemical substances used in the spray system may
be hazardous and toxic to you, bystanders, animals,
plants, soils or other property.

protect yourself according to the chemical
manufacturer's recommendations. For example,

chemical used and information on each should
be assessed.

system has been triple rinsed and neutralized
according to the recommendations of the
chemical manufacturer(s).
• Verify there is an adequate supply of clean water
and soap nearby, and immediately wash off any
chemicals that contact you.

If using a spray pressure greater than 45 psi (3.1 bar)
adjust the dampener accordingly.
