SPECIFICATIONS
Motor: Permanent magnet, double ball bearing arma-
ture. Electronic speed control built into rear
endbell.
Pump: Four chamber positive displacement
diaphragm design. Self-priming up to 10 feet
suction lift. Pump able to run dry without
damage. Removable port adapters.
Mount the pump in a dry, ventilated location. The inlet
strainer must be installed between the fresh water
supply and the pump inlet port. The supply tank should
be at least half full prior to initial operation.
IMPORTANT: Polarity of electrical connections is very
important. Insure that the RED (+) motor lead is
connected to a fused positive d.c. circuit. The BLACK (-)
motor lead must be connected to the negative DC
circuit. In the event that polarity is reversed fuse found in
the “EMI Filter Box” must be replaced.
Sensor VSD™ pumps require a battery to be installed
in the DC power supply when using an AC to DC
converter or battery charging system.
To prime the plumbing system, open all the faucets and
turn on the power to the pump. Shut off each faucet as
it begins to run free of air. As the last faucet is closed the
pump will slow down and shut off.
