INSTALLATION STEPS
Installation of this unit may take several hours. Before disabling your main pump, have ready appropriate
means of evacuating the sump.
STEP 1
Unplug the main AC pump when installing the backup pump to avoid
electric shock. Failure to do so could cause serious injury or death.
STEP 2
Check valve: If you install your emergency 12 V pump using the same
discharge pipe of your main 115V pump, a check valve is required
between the T or Y connection and both pumps. We supply a check
valve with this back-up pump system. Be sure your main 115V pump is
equipped with a check valve (see Figure.1). These check valves are
required to prevent backflow to the sump pit.
STEP 3
We strongly suggest to run your discharge pipe with 1 1/2" rigid PVC
piping.
STEP 4
The back-up pump must be installed at 45° angle (see Figure. 2) to
prevent airlocking.
STEP 5
Screw the supplied adaptors and check valve to the pump discharge
using TEFLON tape (see Figure. 3).
STEP 6
Glue a 45° fitting to the check valve to maintain the pump in same
position as per picture 2 and 3.
STEP 7
Measure and cut a discharge pipe so that back-up pump is 4" to 8"
above the bottom of the sump pit.
STEP 8
Connect the discharge pipe of back-up pump to the discharge pipe of
the main pump using a Y and a 45° fitting as per Figure. 4.
STEP 9
Be sure all connections are well glued.
STEP 10
Attach the float switch to the back-up pump discharge pipe using the
enclosed tie-wrap, as per Figure. 4. The standby pump's float switch
should be installed so that it will not activate until standby pump's inlet is
under water. Make sure power wires do not interfere with float switch or
pump inlet.
STEP 11
Place battery box within 3 feet of the sump and install an 115V AC
separately fused outlet within 5 feet of the control box. The electrical
outlet must be protected by a ground fault circuit interrupter (GFCI). The
area must be also clean, dry and well ventilated.
