PUMP INSTALLATION
Set the pump on the bottom of the sump, making sure that
it sits solidly and is level. Be sure there is enough space
around the punlp to allow the switch frec mo_ cnlcnt ;is the

.I of flooding. If a flexible discharge
hose is used, pump may move around in sump when
niotor starts. If it moves far enough so that tile switch hits the side of the sump, the switch may stick and prevent pump from starting. Make sure that pump is secured so that it cannot walk arotmd in sump.
Hose Kit No. 27909 can be used as the discharge pipe. Run the discharge pipe to the nearest sewer outlet or other point of disposal. Use the most direct route and the fewest turns and elbows possible.
Use Teflon tape to seal threads in plastic pipe. Hand tighten only.
NOTE: To avoid backflow into sump when pump shuts off, install a Check Valve, SEARS Stock No. 2789, in threaded dis- charge port of pump. A SEARS No. 2789 Check Valve is con- structed with an
just above the pump discharge port and below the Check Valve to prevent pump from airlocking.

AUTOMATIC FLOAT SWITCH
INSTALLATION AND OPERATION
Your SEARS Model 390.305001 Submersible Drainer comes
with the automatic float switch mounted on the motor hous-
ing ready for operation. Tether length is factory set at 3"
(76mm). Do not change tether length. See Page 6 for verti- cal float switch instructions.
I AWARNING_ Risk of electric shock. Always disconnect
the pump and switch from the electrical power source
before doing any maintenance!
Follow instructions below to install pump with factory
mounted switch:
1.Be sure automatic float can swing freely through its entire
arc without interference from pump, piping, sump wall or any other object.
2.Plug the automatic switch cord into a properly grounded
outlet (see "Electrical Connections", Page 4). Plug the pump power cord into the back of the switch plug.
3.Test the installation by adding water to the sump pit until
pump operates normally as follows:
A.When sump is dry, the watertight automatic float
switch is hanging in a downward position and the pump is off.
| B. As water | comes | into | the |
| sump, |

Testing for Ground
For your safety, check your outlet for ground using an
Underwriters Laboratory Listed Circuit Analyzer (Figure 3A). A Circuit Analyzer will tell you by a pattern of lights if the
power, neutral, and ground wires are correctly connected
to your outlet. It can also be used to check other outlets in
your home. A Circuit Analyzer is available in the Sears Electrical Department.
