Batteries are hazardous because they contain caustic acid, can emit explosive gases, and can
cause electric shock.
Caution must be exercised when making connections to a battery to avoid shock and contact with
the acid, and to prevent any sparking that could lead to an explosion.
ALWAYS follow the safety instructions and steps listed below i
n exact sequence
when
connecting the pump to the battery terminals.
1. Preparatory
safety
Preparatory safety steps:
•
ALWAYS use eye protection
•
NEVER smoke or work near sparks or other sources of ignition.
•
NEVER touch both battery terminals at the same time or with any
non-insulated tools.
•
If battery acid contacts skin or clothing, flush immediately with water
and neutralize with baking soda.
2. Electrical
requirements
•
The pump should be on a dedicated (individual) circuit, controlled
with a double pole switch (UL/CSA certified) rated at or above the
fuse ampere indicated by the pump motor label. Depending on
distance of the power source from the pump and ampere load on the
circuit, wire may need to be heavier than indicated by the chart.
•
The pump is
protected with a fuse.
Use an approved wire of the size
specified or heavier.

CAUTION:
Improper duty cycle and/or rapid start/stop conditions may
cause the internal thermal breaker (if equipped) to trip, or can result in
premature motor failure due to excessive heat.
3. Connect pump
to battery
Connect the pump to a vehicle battery using the following procedure:
a)
Disconnect the vehicle battery ground wire.
b)
Connect the pump’s
red
wire to the
positive (+)
terminal of the battery.
c)
Connect the pump’s
black
wire to the
negative (-)
terminal of the
battery.
d)
Reconnect the vehicle battery ground wire.
Note:
Skip steps (a) and (d) if battery is not in a vehicle.
WARNING:
Always connect in this sequence to avoid possible shock.
