4. PLUMBING: PUMP AND DISCHARGE PIPING
a) Use steel or plastic pipe for all connecting lines
between pump and sewer outlet. Keep pipe length
to a minimum to reduce friction losses. Pump is
equipped with a 2" NPT female outlet - DO NOT
REDUCE TO A SMALLER SIZE.
NOTE: Fluid fl ow velocity in the pump's discharge line
must be at least two feet per second to carry
the effl uent without clogging. This is ensured
if pump fl ow is at least:
• 21 GPM through a 2" pipe
• 30 GPM through a 2-1/2" pipe
• 46 GPM through a 3" pipe
WARNING:
Some city regulations DO NOT allow
the installation of a pump with plastic pipe. Check lo-
cal regulations.
b) A union or quick disconnect connection should be
installed to facilitate pump removal if necessary. A
FULL FLOW CHECK VALVE IS RECOMMENDED
AFTER THE UNION TO PREVENT BACKFLOW
AFTER EACH PUMPING CYCLE.
NOTE: When a check valve is used, drill a 1/8" or
3/16" air relief hole in the discharge pipe.
This hole should be located below the fl oor
line within the sealed pump unit and between
the pump and check valve (see Fig. 2 & 3).
Without this relief hole, the pump can air lock
and will not pump even though it will run.

5. MOUNTING THE FLOAT SWITCH:
AUTOMATIC OPERATION MODELS ONLY
All automatic models; Single Phase 115 volt
a)
models come supplied with a fl oat switch for mount-
ing to the pump's discharge pipe and requires fi nal
adjustment to suit your systems needs.
The fl oat switch is equipped with a cord and 115
b)
volt grounded piggyback plug confi guration (de-
pending on the voltage rating of the model you
have). The switch provides automatic operation
of the pump in water, effl uent and sewage ap-
plications.
WARNING - RISK OF ELECTRICAL SHOCK
The fl oat switch is packaged separately within the
c)
pump carton and includes the switch manufac-
turer's assembly, adjustment, operation, safety
and cautionary instructions. Follow the manu-
facturer's instructions explicitly for proper
installation and operation. The free length of
cable must be at least 4" to allow free move-
ment of the fl oat.
6. MANUAL MODELS:
SINGLE PHASE 115 VAC MODELS
Single Phase 115 volt manual models DO NOT
a)
INCLUDE A FLOAT SWITCH.
The pump comes equipped with a power cord and
b)
115 volt grounded plug confi guration (depending
on the voltage rating of the model you have).
Plug in or unplug pump power cord as needed into
c)
ground fault interrupter (GFI) protected circuit or
use with an approved motor control that matches
the pump/motor input rated amperes. The mo-
tor control must be properly sized for the pump,
installed and wired in compliance with the National
Electrical Code (NEC) and any local codes and
ordinances.
