STARTING PUMP PIGGYBACK
(AUTOMATIC) USING MECHANICAL SWITCH
WITH SERIES PLUG –
SIMPLEX SYSTEM
1. These pumps have a mechanical (mercury-free) oat
switch with a 20 ft. cord and a 115 volt or 230 volt
series piggyback plug on 1/2 HP with switch mounted
to the pump. On 3/4, 1, and 2 HP, it requires 20 ft.
cord and 230 volt only.
2. Plug the switch cord plug into a proper voltage,
properly grounded outlet.
3. Plug the pump power cord into the back of the switch
cord series plug.
4. Tape the cords to the discharge pipe every 12".
5. Run water into basin until pump starts. Be sure
discharge line valve is open.
6. Allow pump to operate through several on/off cycles.
HOW TO SET CONTROLS AND START
DUPLEX SYSTEMS
CONTROL BOX MUST BE USED ON ALL DUPLEX
SYSTEMS
1. Four oat controls are used for duplex systems. Set
turn-on control 6" to 8" above pumps. Set turn-off
control 8" to 10" above bottom of basin. Set override
control 6" to 8" above turn-on control. Set high level
alarm control about 6" to 8" above override control.
Mark all control cords so that they can be connected
correctly in the control box.
2. Turn Hand-Off-Auto switches to OFF position and
close circuit breaker.
3. Turn both H-O-A switches to the AUTO position and
run water into basin. When level rises and activates
the turn-on switch, one pump should start and
run. Pump will continue to run until lower control is
exposed, stopping pump.
4. Run water into sump again and when water level
raises the turn-on control, opposite pump will start and
run until level drops exposing lower control, stopping
pump.
5. Run this test several times to be sure pumps are
alternating properly.
6. To check high level alarm, again turn both switches
to OFF and ll basin until level is above the alarm
control. Turn switches to AUTO position and alarm
buzzer should sound and alarm light should come
on. When level drops below the alarm, control buzzer
should stop.
7. If pumps operate as described, then set both H-O-A to
AUTO and pumps are ready to operate automatically.
NEVER WORK ON PUMPS OR CONTROL
BOXES UNTIL CIRCUIT BREAKERS ARE TURNED
OFF. Always have a qualied electrician make electrical
connections and service checks.
SPECIAL INSTRUCTIONS FOR 3-PHASE
PUMPS
1.
Only qualied persons shall service
and install this pump. The pump must be wired by
a qualied electrician, using an approved starter
box and switching device.
Risk of electric shock. Do not remove
cord and strain relief. Do not connect conduit to pump.
2. Three phase pumps are always installed with control
boxes having magnetic starters with 3-leg overload
protection. DO NOT TRY TO RUN THREE PHASE
PUMPS DIRECTLY ACROSS THE LINE.
3. To Connect Pump: Run wire from pump to the
bottom of control box or appropriate junction box
suitable for enclosing splice connections. A hole must
be cut into the control box for the wires. With power to
control box off, connect green (ground) line to ground
lug. Connect black (power) wires to power lead
terminals. Make sure that all wires are inside control
box and not in a position to be pinched or shorted
when the door is closed.
4. All three phase motors can run either direction.
Rotation can be changed by interchanging any two
line leads at magnetic starter. BE SURE CIRCUIT
BREAKER IS OFF BEFORE MAKING THIS
CHANGE.
To nd if rotation is correct, operate pumps and check
delivery operation. If ow and head are low, the
rotation is wrong. With duplex pumps check operation
of both pumps.
5. All pump impellers either single or three phase must
turn counterclockwise when looking into pump inlet.
If uncertain of rotation, TURN OFF POWER and lift
pump from basin USING THE LIFTING RING (with
cord connected) and lay pump on side so impeller can
be seen. Turn on power and start pump using hand
position of H-O-A switch. Turn on and off fast, so that
coast of impeller can be seen.
RISK OF AMPUTATION WHEN PUMP
STARTS. Never put hand or ngers on the impeller.
Interchange any two line leads at the magnetic starter to
change rotation.
