• Pump must be plugged into an outlet recepta-
cle that includes a Ground Fault Circuit
Interrupter (GFCI) (Figure 1) .
• Always disconnect the power source before
attempting to install, service, relocate, or main-
tain the pump. Never handle a pump or pump
motor with wet hands or when standing on wet
or damp surface or in water.
Installation
1. Construct a sump pit from concrete, steel, or plas-
tic that is 24" deep and at least 11" in diameter
(Figure 2 next page) . If the sump already exists,
make sure it is the proper size.
2. Make sure the electrical outlet is grounded and is
rated for 115 volts and at least 15 amps. The out-
let must be protected by a Ground Fault Circuit
Interrupter (GFCI).
WARNING
!
Use of a grounded receptacle that
is protected by a GFCI reduces risk of a fatal electrical
shock.
3. Inspect the power cord and plug for damage. If the
plug is missing the grounding prong or the cord is
damaged, do not install the pump until the cord has
been replaced.
(Model SP-330D Diaphragm Switch only)
4. Remove the two fasteners in the cast iron volute
near the discharge area. Align the hole with the
diaphragm switch and replace the fasteners with-
out over tightening.
