Product Manual
4 Rev. - 922123-01
An automatic bypass valve prevents pressure buildup
when the pump is on with the nozzle closed. To avoid
pump damage, do not run the pump for more than 10
minutes with the nozzle closed.
Motor Protector (Models M-150S and M-180S only)
The pump contains a motor protector that provides
added protection against motor damage. It must be
reset manually.
If the motor protector trips, reset by turning the switch
OFF. Let the pump cool then turn ON again. If the motor
protector trips again, see the Troubleshooting Section
of this manual.
Motor Protector (Model M-240S)
An inline fuse provides motor protection on the 24-volt

strainer coverplate. (Figure 5) Remove the inlet strainer
and inspect for damage or clogs. Clean the strainer with
a soft-bristled brush and solvent. If the strainer is very
dirty, compressed air may be used. If damaged, replace
the strainer.
Place the strainer in the cavity. Clean the coverplate
and O-ring. Coat the O-ring lightly with grease. Ensure
the coverplate O-ring is properly seated and tighten the
strainer coverplate.
FIGURE 5
Carefully route the power cord to the battery, protecting the power
cord from hot surfaces, sharp edges or anything that could dam
-
age the power cord, resulting in a short circuit.
A fuse is provided to protect the power cord and motor. Install
fuse in the red wire of the power cord as close as possible to
the battery. Connect the red wire of the fuse to the positive (un
-
grounded) side of battery. Connect black wire to the negative
(grounded) side of the battery.
Failure to follow these instructions could result in death, serious
injury or loss of equipment due to short circuit, re or explosion.
WARNING
If the pump is to be installed in a Hazardous (Classied) loca-
tion, it must be installed by a licensed electrician and conform
to National Fire Protection Association (NFPA) codes 30 and 70.
You as the owner, are responsible for seeing that the installation
and operation of your pump complies with NFPA codes as well
as any applicable state and local codes. Rigid conduit must be
used to install wiring. Note that the lead wires are factory-sealed
isolating the motor from the junction box.
Failure to follow these wiring instructions may result in death or
serious injury from shock, re or explosion.
DANGER
