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:
WARNING:
Some city regulations prohibit the
installation of a pump with plastic pipe. Check local
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.

INSTALLATION
5. MOUNTING THE FLOAT SWITCH:
AUTOMATIC OPERATION MODELS ONLY
All automatic models; Single Phase 115 and
a)
230 volt models come supplied with a fl oat switch
for mounting to the pump's discharge pipe and
requires fi nal adjustment to suit your systems
needs.
16
The fl oat switch is equipped with a cord and 115
b)
or 230 volt grounded piggyback plug confi guration
(depending on the voltage rating of the model you
25
have). The switch provides automatic operation
of the pump in water, effl uent and sewage ap-
plications.

WARNING - RISK OF ELECTRICAL SHOCK
76
The fl oat switch is packaged separately within the
c)
110
pump carton and includes the switch manufacturer's
195
assembly, adjustment, operation, safety and cau-
305
tionary instructions.... Follow the manufacturer's
440
instructions explicitly for proper installation and
operation. The free length of cable must be at
least 4" to allow free movement of the fl oat.
6. MANUAL MODELS:
SINGLE-PHASE 115 AND 230 VAC MODELS
Single Phase 115 or 230 volt manual models DO
a)
NOT INCLUDE A FLOAT SWITCH.
The pump comes equipped with a power cord
b)
and 115 or 230 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 motor 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.
7. MANUAL MODELS: THREE PHASE 230, 460
AND 575 VAC MODELS
Three Phase 230, 460 and 575 volt manual models
a)
DO NOT INCLUDE A FLOAT SWITCH.
The pump comes equipped with a three phase
b)
power cord without plug for use with approved
motor control that matches pump/motor rated
amperes with overload element(s) selected or
adjusted in accordance with the control manu-
facturer's instructions.
Three phase motor control must be properly sized
c)
for pump, installed and wired in compliance with
the National Electrical Code (NEC) and with any
local ordinances.
