INSTALLATION (New Pump)
1. Set your new pump in the bottom of the sump basin off to one side. The pump should be
placed on a solid foundation. Do not place the pump directly on the ground or sandy or
rocky surfaces. Sand and small stones may clog or cause damage to your pump.
2. Make sure the float switch will swing freely from the bottom to top without coming in
contact with the side of the sump basin. Contact with the side of the sump basin may
cause the switch to malfunction. See figure below.

3. It is highly recommended to install a full flow, swing type check valve (not included)
as close to the discharge outlet on the pump as possible. A new check valve will
greatly increase the life of your pump. The check valve should be the same size as
the pump discharge.
4. Connect the pump and check valve together using schedule 40 PVC pipe and
fittings. You can also use DWV or ABS pipe, as this is not a pressure installation.
Corrugated drain hose is intended for temporary use and should not be used in a
permanent installation.
Vertical Switch Installations
Grounded Outlet. A GFCI outlet
is strongly recommended.
Full-flow swing type check valve
Discharge Pipe
Sump basin. Min. 14" diameter
Position pump so the float switch
operates freely without touching
the sides of the basin.

5. Test your installation after you have completed setting up the pump. Plug the cord
from the pump into the piggyback plug of the float switch, then plug that into your
grounded outlet. The pump should not run at this point. If the pump runs, the
switch is stuck in the upright position or the pump is plugged directly into the outlet
and not through the piggyback switch plug. Fill the sump basin with water using
buckets or a hose. When the switch floats to the upright position, the pump will turn
on. The switch will turn off the pump when it reaches the down position. You may
adjust the switch to meet your particular needs. Remember the switch must swing
freely without touching the sides of the sump basin. NOTE: The cut out (turn off)
setting is the only adjustment available on vertical type switches.
TROUBLESHOOTING
PROBLEM POSSIBLE CAUSES
 Pump is not plugged in, switch or
breaker is off
 Check for blown fuses or tripped circuit
breakers or tripped GFCI outlets
If the pump does not
 Float switch is defective
start or run
 Motor thermal protector tripped
 Float switch is stuck or obstructed
 Backflow of water from discharge
The pump starts and
hose/pipe
stops too often
 Float switch is defective
 Clogged intake screen
 Clogged discharge hose/pipe
 Frozen discharge hose/pipe
 Pump is air locked
 Low line voltage
If the pump runs but
moves little or no water
 Check valve is stuck in the closed
position
 Check valve is installed backwards
 Worn, damaged or clogged pump parts
 Discharge head exceeds pump
capacity
 Float switch is obstructed or stuck
Pump does not
shut off
 Defective Float Switch
HOW TO CORRECT
 Plug pump in or turn on
switch/breaker
 Replace fuse, reset breaker, reset
GFCI outlet
 Check and replace if necessary
 Allow pump to cool. Pump will reset
 Remove obstruction or position pump
so it will not become stuck
 Install or replace check valve
 Replace float switch
 Clean or replace screen
 Remove clog
 Allow hose/pipe to thaw
 Clean out airlock hole with a paper
clip or pipe cleaner
 Check wire size and increase if
necessary
 Inspect, repair or replace if necessary
 Make sure valve is installed in the
correct direction of flow
 Inspect for wear, damage or clog and
clean or replace if necessary
 If pumping height is over 25', the
pump will not move water. See
performance chart
 Remove obstruction
 Replace switch
