A ground fault circuit interrupter is recommended for use
with any electrical appliance submerged in water. For
installation of such a circuit, consult a licensed electrician.
6. After the piping and the check valve (if needed) have
been installed, the unit is ready for operation
7. Check the operation by filling the sump with water and
observing pump operation through one complete cycle.
Risk of flooding. Can cause personal
injury and/or property damage. Failure to make this oper-
ational check may lead to flooding and premature failure.
OPERATION / MAINTENANCE
Risk of electric shock. Can burn or cause
death. Before attempting to check why unit has stopped oper-
ating, disconnect the power from the unit. Do not handle the
pump with wet hands or when standing on wet or damp sur-
faces, or in water.
1. The shaft seal depends on water for lubrication and cool-
ing. Do not operate the pump unless it is submerged in
water as the seal may be damaged if allowed to run dry.
2. The motor is equipped with an automatic reset thermal
protector. If the temperature in the motor should rise
unduly, the switch will cut off all power before damage can
be done to the motor. When the motor has cooled suffi-
ciently, the switch will reset automatically and restart the
motor. If the protector trips repeatedly, unplug the pump
and remove it; check for cause of difficulty. Low voltage,
extension cords, clogged impeller, very low head or lift,
etc., could cause cycling.
Risk of sudden starts. Can cause electrical
shock and personal injury. The pump motor is equipped
with automatic resetting thermal protector and may restart
unexpectedly.
3. The pump will not remove all water.
NOTICE: For continuous operation, water depth must be at
least 5" (13cm) to prevent motor overheating.

AUTOMATIC FLOAT SWITCH -
INSTALLATION
1. Install the pump following the installation and operating
instructions.
2. The automatic float switch is sealed and factory adjusted
for most home sumps. See Page 3 for the switch settings.
NOTICE: Minimum recommended turn-off level above pump
base is 5" (13cm).
3. Be sure the horizontal float switch clearance is 8"
(203mm). For best performance of pumps with tethered
switches, the sump diameter and sump depth should be at
least 12" (305mm).
Risk of flooding. Can cause personal
injury and/or property damage. May lead to improper
operation or premature failure. If a flexible discharge hose
is used, the pump may move when the motor starts. If the
switch hits the side of the sump, the switch may stick and
prevent the pump from starting. Make sure the pump is
secured so it cannot move around in the sump.
4. Plug the piggyback switch cord into a 115V AC outlet.
Then, plug the pump into the plug on the piggyback
switch cord.
Do not allow the cord to interfere with the float control
motion or to drape over the pump motor. With electrician's
tape or cable ties secure the cord to the discharge pipe for
cord protection.
FLOAT SWITCH - OPERATIONAL CHECK
1. Fill the sump with the correct amount of water to check
the operation and tightness of the connections. During the
first automatic cycle, it may take 30 seconds or more
before the pump is primed and pumping. The pump will
start as indicated in the "Motor, Switch and Cord
Specifications" Table, Page 3.
2. Check the turn-off position. The pump will stop approxi-
mately as indicated in the "Motor, Switch and Cord
Specifications" Table, Page 3.
3. If the pump does not operate check the electrical service.
NOTICE: The float switch tether length is set at the facto-
ry. It is 3-1/2" (89mm). Do not change the tether length
of the float switch. Float must be able to swing through
its complete arc without interference.
