Wayne WLS75 - Manual (Page 3)

If the pump does not operate after
repeated attempts, check the following:
1. Vertical distance of pump to water
level must not be over 25 feet.
2. Suction piping must be air tight.
3. Be sure valve(s) are open if used in
discharge or suction piping.
Never run the
pump with a closed
or clogged discharge. The water inside
the pump could boil and damage the
pump.
Maintenance
Maintain adequate ventilation for the
pump motor. The motor bearings are
permanently lubricated at the factory.
Additional lubrication is not required.
DRAINING FOR WINTER
Always protect pump and piping
against freezing temperatures. If there
is any danger of freezing, drain the
system. To drain the system:
1. Remove the pipe plug from the
discharge tee.
2. Remove the 1/4” plug from the
lower front face of the pump.
3. Drain all piping below the frost line.

Operating Instructions and Parts Manual
pump in accordance with the National
Electrical code and all applicable local
electrical codes.
The motor must be grounded by
connecting a copper conductor to the
grounding screw provided within the
wiring compartment.
The voltage of power supply must match
the voltage of the pump. The WLS75,
WLS100 and WLS150 have dual voltage
motors preset at the factory to 230 volts.
The motors can be converted to 115 volts
by turning the voltage selector to the
desired voltage (See Figure 5). Use a
needle nose pliers to pull the selector out
approximately 1/4”, rotate and then
reinsert in correct position. The WLS200
cannot be converted; the motor is
230 volts only.
CONNECTING WIRES
Terminal cover must be in place for safe
operation. Ground in accordance with local
and national electrical codes. Keep fingers
and objects away from openings and
rotating parts. Disconnect power sources
before touching internal parts. See figure 6
for appropriate wiring locations.
Operation
Never run the
pump dry. Running
pump without water may cause seal
damage. Fill the pump with water
before starting.
PRIMING THE PUMP
After pump installation is complete, the
pump must be primed. Remove the
pipe plug in the discharge piping and
fill the pump and suction pipe with
clean water. Turn power to pump on. If
the pump does not pump water in 10
minutes, turn off the pump and refill
with clean water.
