ELECTRICAL
hazardous Voltage. Can cause severe or
fatal electric shock. Pump is supplied with a grounding
conductor and ground ding-type attachment plug. To reduce
risk of electric shock, be certain that it is connected only to a
properly grounded, grounding type receptacle. Ground
terminal on pump cord plug is provided for your protection.
DO NOT REMOVE!
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.
OPERATION / MAINTENANCE
Risk of electric shock. Before attempting to
check why unit has stopped operating, disconnect power
from unit. do not handle pump with wet hands or when
standing on wet or damp surfaces, or in water.
Risk of flooding. If a flexible discharge hose
is used, pump may move when 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 sump.
Risk of sudden starts. The pump motor is
equipped with automatic resetting thermal protector and
may restart unexpectedly.
1.
If protector trips, motor may be overloading. Check for
the following problems:
a.
Not enough back pressure in discharge pipe.
b.
Voltage too high or too low.
c.
Wires to motor too small.
d.
Motor incorrectly connected to power supply wires.
e.
Defective motor.
2.
Shaft seal depends on water for lubrication and cooling.
Do not operate pump unless it is submerged in water as
seal may be damaged if allowed to run dry.
3.
Motor is equipped with automatic reset thermal
protector. If temperature in motor should rise unduly,
switch will cut off all power before damage can be done
to motor. When motor has cooled sufficiently, switch will
reset automatically and restart motor. If protector trips
repeatedly, unplug the pump and remove it; check for
cause of difficulty. Low voltage, long extension cords,
clogged impeller, very low head or lift, etc., could cause
cycling.
4.
Pump will not remove all water. If manually operated
pump is operating and suddenly no water comes out
discharge hose, shut off unit immediately. Water level is
probably very low and unit has broken prime.
CLEANING ANd REPLACING
IMPELLER
1.
Unplug the pump.
2.
Loosen the clamps on the hose and clamp assembly.
3.
Slide the hose and clamp assembly up on the discharge
pipe and remove the pump from the sump.
4.
Turn the pump upside down and remove the screw
securing the pump screen.
5.
Loosen and remove the clamp that holds the lower and
upper pump housings together. Remove the lower pump
housing.
6.
Hold the motor shaft with a screwdriver in the slot on the
bottom end of the shaft, and unscrew the impeller off of the
shaft.
7.
Clean and replace the impeller as necessary.
8.
Reverse Steps 1 through 6 above to replace the impeller
and reinstall the pump.
9.
Fill the sump with water and run the pump through
one complete cycle to make sure that it is correctly
reassembled and operating as it should.

INSTALLATION
1.
Install pump following installation and operating
instructions.
2.
Automatic float switch is sealed and factory adjusted for
most home sumps. See Page 1 for switch settings.
3.
Be sure that horizontal float switch clearance is 8". For
best performance of pumps with tethered switches,
sump diameter and sump depth should be at least 14".
4.
Plug piggyback switch cord into 115V AC outlet. Then,
plug pump into piggyback switch cord. Do not allow cord
to interfere with float control motion or to drape over pump
motor. With electrician's tape or cable ties secure cord to
discharge pipe for cord protection.
FLOAT SWITCh -
OPERATIONAL ChECK
1.
Fill the sump with correct amount of water to check
operation and tightness of connections. During the
first automatic cycle, it may take 30 seconds or more
before pump is primed and pumping. Pump will start as
indicated in the "Motor, Switch and Cord" Specifications
Table, Page 1.
2.
Check turn-off position. Pump will stop approximately as
indicated in the "Motor, Switch and Cord" Specifications
Table, Page 1.
3.
If pump does not operate check electrical service.
NOTICE: Float switch tether length is set at factory. It is 3"
(76mm) for SP75 Series pumps. Do not change tether length
of float switch. Float must swing through its complete arc
without interference.
