INSTALLATION
BACKUP ASSEMBLY INSTALLATION
Attach backup pump assembly to primary pump. To do so,
un-screw bottom nut on check valve and remove rubber seal.
Place nut from check valve around discharge PVC pipe on
primary pump, then place rubber seal. Attach backup pump
assembly to the primary pump by tightening nut to the rest
of the check valve unit. Adjust backup pump to sit at an angle
(approx. 10°).
FLOAT SWITCH INSTALLATION
Assemble float switch as shown.
COMBO UNIT INSTALLATION
Suggested Materials Needed:
Screwdriver, tape measure, hacksaw, and cable ties.
1. Drain the sump pit as far as possible without running the
pump dry. Do this by:
Piggyback switch: Unplug the pump and switch from
the outlet, then unplug the pump from the piggyback
switch. Reset the circuit breaker or reinstall the fuse
and plug the pump directly into the outlet. The pump
will start. Drain the pit and unplug the pump. OR
No piggyback switch: Reset the circuit breaker or
reinstall the fuse and use a non-conducting broom
handle or stick to raise the float switch; the pump
should start. Drain the pit and then release the
switch.
When the pit has drained, turn off (open) the circuit breaker or
remove the fuse again to avoid electrical shock while working
on the installation. Unplug existing sump pump and place
power cord and piggyback switch out of the way of work and
water.
2. Measure height of FG-3100RC Combo Kit from base to top
of hose clamp assembly. Subtract 1”.
Drop the tape measure into the bottom of sump pit and
mark the cut line on the discharge pipe (1” less than total
height of the Combo Kit).
3. Use hacksaw to cut horizontally along cut line completely
through pipe.
Note
:
Depending on where your current check valve is
located, there may be excess water. Let the water drain/
drip into the sump pit.
4. Remove old sump from sump pit.
Note
:
Remove all sand, clay, and gravel before installing.
5. Place Combo Kit into sump pit. Make sure vertical float
switches can operate freely inside sump pit.
