vere burns and start a fire if battery terminals are short cir-
cuited. Install battery in box. To prevent accidental shorting across battery terminals, strap cover securely on battery box.

Your Backup Sump Pump depends on the battery used with
it for power. The better the battery, the better the perfor- mance of the pump. We recommend use of a SEARS DieHard
Size 27M or 24M
In an emergency a SEARS DieHard Size 27M or 24M standard
automobile battery may be used. However, an automotive battery may require charging after only 1 to 2 hours of con-
tinuous use, and the repeated charging cycles may cause early plate failure in the battery.
Use ordy a new, fully charged battery that will fit in the bat-
PU M P I NSTALLATION
and OPERATION
NOTICE: We recommend a trial fitting of all components
before gluing anything. This will allow you to check pump
mounting height, float switch clearance, etc., while adjust- ments can still be easily made.
1 .Mark side of sump six inches down from top.
2.Fill sump until primary sump pump starts; normal high water level should not be above mark made in step 1. If it is higher, backup float switch may not swing far enough
for proper operation. To lower high water level, adjust
switch on primary sump pump. See primary pump

5. Cut rigid discharge pipe from primary sump pump to length. Use PVC piping. Tee supplied is
NOTICE: Use any tee that fits sump pump discharge line; the adapter that is supplied (Key No. 10, Page 7) will fit

6.Thread adapter into tee (Figure 2B). When installed,
7.Install backup pump check valve in adapter. Tab on
backup pump check valve fits into notchat top of adapter.
8.For trial assembly, slip pump into backup pump check
valve to check pump mounting height and to make sure
that there is no interference with float switch operation on either pump; be sure floats will not rub on side of
sump, catch between pump and sump wall, interfere with each other, etc.
9.Remove pump from adapter; remove tee.
lO.Using PVC glue, permanently reinstall tee in primary sump pump discharge pipe.

3.Drain sump. Measure down 11 inches from top of sump; mark this point on side of sump. Install tee with center of threaded inlet at least this far below top of sump to allow sufficient room for float switch to swing (see Figure 2A).
4.Make sure that installation will not interfere with primary
sump pump operation as follows:
A.Backup pump installation must not interfere with pri- mary sump pump float switch swing.
B.Normal high water level must never be high enough to start backup sump pump.
C.Install a check valve (SEARS Stock No. 2789) in the
main sump pump discharge pipe between the pump and the backup mounting tee (see Figures 2A and 2B).
