In a double-insulated product, two sys-
tems of insulation are provided instead of
grounding. No grounding means are pro-
vided for a double-insulated product, nor
should grounding means be added to the

product requires extreme care and knowl-
edge of the system, and should be done
only by qualified service personnel.
Replacement parts for a double-insulated
product must be identical to the original
parts. A double-insulated product is
marked with the words “Double
Insulation” or “Double Insulated.”
Product may also be marked with symbol
shown below.

that exceeds the operating pressure of
any of the parts (hoses, fittings, etc.) in
the pressurized system. Ensure all
equipment and accessories are rated to
withstand the maximum working
pressure of the unit.
