ELECTRICAL
Hazardous Voltage. Can cause severe or
fatal electric shock.
Pump is supplied with a grounding con-
ductor 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 termi-
nal on pump cord plug is provided for your protection. DO
NOT REMOVE!
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 automati-
cally and restart motor. If protector trips repeatedly,
unplug the pump and remove it; check for cause of diffi-
culty. 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 dis-
charge hose, shut off unit immediately. Water level is
probably very low and unit has broken prime.
NOTICE:
For continuous operation, water depth must be
at least 5" (127mm) to prevent motor overheating.
AUTOMATIC FLOAT SWITCH -
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”. For
best performance of pumps with vertical switches, sump
diameter must be at least 10”.
4.
Plug piggyback switch cord into 115V AC outlet. Then,
plug pump into piggyback switch cord.
NOTICE:
Call Customer Service for minimum recom-
mended turn-off level above pump base.
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 oper-
ation an tightness of connections. During the first auto-
matic 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
3-1/2” (89mm) for D125, D133, and D150 Series and 3”
(76mm) for D175 Series pumps. Do not change tether
length of float switch. Float must swing through its com-
plete arc without interference.
To Clean Impeller
D125, D133 and D150 Series Models
Follow steps 1, 2, 3, and 4, shown below. To reassemble
pump, reverse the sequence.
A. Complete repairs and replace pump in pit before plug-
ging it in again.
B. Do not raise, lower, or carry pump by the power cord.
use the tee-handle provided.
