OPERATION − SECTION C
Review all SAFETY information in Section A.
Follow the instructions on all tags, labels and
decals attached to the pump.
PUMP OPERATION
Do not operate this pump where explo-
sive vapors or flammable material exist.
Death or serious injury will result.
Check the National Electric Code
(N.E.C.) and local codes before using.
This pump is designed to handle dirty
water that does not contain large en-
trained solids. It is not designed to
pump volatile, flammable or corrosive
materials. Do not attempt to pump any
liquids which may damage the pump or
endanger personnel as a result of pump
failure.
Install the pump and piping as described in IN-
STALLATION, Section B.
Switching
The ON-OFF switch for the pump is located on the
power cable. With the switch in the OFF position, a
safety interlock circuit eliminates arcing when the
cable is connected to the battery. Arcing may oc-
cur if the switch was left ON because the pump was
stopped after its last operation by disconnecting
the battery clips without using the switch. Always
make sure the switch is in the OFF position before
connecting to the vehicle battery.
Running Time
The pump draws about 30 Amps, and can be oper-
ated for about 45 minutes on a fully-charged 55
AMP-hour battery, and still permit starting of the ve-
hicle under normal conditions. Caution should be
used when the running time exceeds 30 or 40 min-
utes without the engine running to recharge the
battery, particularly in cold weather when the bat-
tery efficiency is lowered. Battery size (AMP-hour
rating) and the use of other accessories such as
the lights and radio, must be taken into consider-
ation for practical running periods without the ve-
hicle engine running.
Do not operate an internal combustion
engine in an explosive atmosphere.
When operating internal combustion
engines in an enclosed area, make cer-
tain that exhaust fumes are piped to the
outside. These fumes contain carbon
monoxide, a deadly gas that is color-
less, tasteless, and odorless.
Overload Protection
Overload protection is provided by means of a 40
Amp automatic reset circuit breaker located inside
the motor cover on top of the pump.
Operational Checks
Check the pump for proper operation when it is first
started and periodically thereafter to identify minor
problems.
Check the pump for unusual noises or excessive
vibration while it is operating. If noise or vibration is
excessive, stop the pump and refer to the
troubleshooting chart for possible causes.
Check the pump strainer screen for clogging
caused by stones, sticks, or other debris. Clean
the strainer screen when required. In some cases,
stopping the pump momentarily may back flush
