WARNING
Proper electrical grounding is essential to reduce
the risk of fire or explosion which can result in seri-
ous bodily injury and property damage. See the
warning section FIRE OR EXPLOSION HAZARD
on page 3 for more detailed grounding instructions.
4 Check the electrical service to be sure it is appro-
priate for your sprayer 's wiring. See the next
paragraphs. Use a properly grounded outlet. Do not
remove the grounding prong of the power supply
cord. Do not use an adapter. Extension cords must
have 3 wires of a minimum 12 gauge size. Long ex-
tension cords reduce sprayer performance; use a
longer hose rather than a longer extension cord.
Models 226–433 and 231–004 require 1 15 Volt, 60
Hz AC, 20 Amp electric service , equipped with a
NEMA NO. 5–20P plug. Since the unit draws 20
amps, use it only on a separate circuit with no other
loads.

NOTE: A licensed electrician can rewire Models
226–433 and 231–004 for 230 volt service, if
necessary. See the wiring diagram in Fig 2.
Model 226–432 requires 220 Volt, 50 Hz AC, 15 amp
electric service. Have a licensed electrician install a
plug conforming to local code.
5 With the ON/OFF switch OFF, plug the cord into
a grounded electrical outlet located at least 20 ft.
(6 m) away from the spray area.
6 Flush the pump. See page 10.
Prepare the paint. Follow the paint manufacturer's
7
recommendations. Remove any paint skin. Stir to
dissolve hard pigments. Strain the paint through a
fine nylon mesh bag to remove particles that could
clog the filter or spray tip. This is probably the most
important step toward trouble-free spray painting.
