LEVEL CONTROLS
All pumps must use certied level control switches for
automatic operation. Level control rating must be at least
equal to the horsepower rating of the pump.
Plug-in cords can be used on all the single phase pumps
without seal leak detector. This cord has a GROUND
pin that plugs into a grounded receptacle. The grounded
receptacle cannot be used in the wet sump or basin due
to DANGER of current leakage.
Sealed junction boxes must be used in wet sumps or
basins to make connections to motor cord.
MOTOR TYPES
All single phase pump motors have internal capacitors.
Automatic reset overload switches are attached directly
to the motor windings on single phase pumps.
Three phase pump motors are squirrel cage induction
type.
INSTALLATION
Pumps can be installed inside sealed basins with proper
venting for either simplex or duplex systems. Simplex or
duplex basin systems are available.
Basins are not intended for use with home septic
systems. They are for use in ofce buildings and small
industrial buildings and factories.
If raw sewage must be pumped from the home's sewage
system, use outside basins that connect with pressure
sewer mains or gravity sewers, or run to septic tanks.
Basins can be used inside the home where extra capacity
sump pumps are required for water softeners and wash
water.
If an inside basin is used, it is usually installed at the time
of pouring the concrete basement oor.
Pumps can be installed in a compartment of septic tanks
for pumping to pressure sewer mains, gravity sewers,
leach elds, or evaporation mounds.
PROPER VENTING FOR BASINS INSTALLED
INSIDE
All inside sealed basins must have a 2" or 3" vent pipe
installed in accordance with local codes. Basins for
handling softener water, wash or drainage water do not
have to be sealed or vented.
Outside basins are usually of berglass and from 4 to
8 feet deep and have a sealed cover. Pump is usually
installed with a lift-out rail system so that pump can be
removed without disturbing the discharge piping. The
check valve comes out with pump for servicing. Complete
lift-out systems mounted in berglass basins are
available to meet customer specications.
Basin must be vented in accordance with
local plumbing codes. These pumps are not designed
for and CANNOT be installed in locations classied
as hazardous in accordance with the National
Electric Code.
PIPING
Pumps are tted with 2" or 3" female threaded pipe
ange. Galvanized or PVC plastic pipe can be used.
Plastic pipe is preferred for raw sewage or septic tank
efuent.
CHECK VALVES AND SHUT-OFF VALVES
All pumps must have check valves and shut-off valves
in the discharge line. Check valves must be apper type
with outside spring or ball type. Shut-off valves can be
ball or gate type. Plastic construction for both check and
shut-off valves is preferred.
HOW TO SET CONTROLS FOR SIMPLEX
SYSTEMS
1. Automatic systems — These systems have the
oat switches mounted on the pump, so pump is
installed in the basin and motor cord is plugged into
GROUNDED receptacle. For sealed basin cover,
power cord is brought through a split rubber plug in
the basin cover.
2. Where 2 oat controls are used, the turn-on control
is set 3" to 6" above top of motor, and the turn-off
control is set about 6" to 8" above bottom of basin.
If a high level alarm control is used, it is set about 6"
above upper control. If basin depth will not allow these
settings, closer spacing can be used.
HOW TO START SIMPLEX SYSTEMS
1. For single-phase pumps with plug cords piggyback
into receptacle and run water into basin until pump
starts. Allow pump to make several on/off cycles.
Leave power cord plugged in.
If pump runs but does not pump it may be air locked.
Unplug cord and crack union in the discharge line,
then restart pump. This should vent off any trapped
air. Retighten union.
2. With 2 oat controls turn on power at the control box
and run water into basin. When level gets above top
control, pump should start and continue to pump
until level drops to lower control, stopping pump. Run
pump through several cycles. If pump runs but does
not pump, turn off power and check for an air lock.
Leave power on for automatic operation.
For all cases if motor does not start when water level is
up, check for proper plug-in or that start switch is on, or if
fuse is blown.
ALWAYS HAVE ELECTRICIAN MAKE ELECTRICAL
CHECKS.
