Typical Sewage/Waste Pumping System Installation
ZEPA0562
(1) Electrical wiring and protection
must
be in accordance with the
National Electrical Code per NEC articles 500 through 503 for
installation in Class 1, Division 1, Group C & D environments,
and any other applicable state and local electrical requirements.
(2) Install proper full flow check and shut-off valve.
(3) Install proper controls. (Outdoor panels in ventillated areas
require
NEMA 3R or 4X enclosure) Float switch connections
shall be intrinsically safe.
(4) All installations
require
a basin cover to prevent debris from
falling into the basin and to prevent accidental injury.
(5) Cords must be properly sealed per NEC articles 500 through
503 for installation in Class 1, Division 1, Group C & D environ-
ments, to prevent moisture and gases from entering the control
panel.
(6)
When check valve is installed
, drill a 3/16" diameter hole in
the discharge pipe below the check valve even with the top of
the pump. NOTE: The hole must be below the basin cover and
cleaned periodically. Water stream will be visible from this hole
during pump run periods. Also a vent hole is drilled in the pump
housing. Be sure that this hole is cleared during any servicing.
(7) Vent gases and odors to the atmosphere through vent pipe per
Local and State codes.
(8) Secure power cord to avoid entanglement with variable level
float switch mechanism.
(9)
Do not
reduce pump discharge pipe below 3" IPS size.
(10) Basin
must
be in accordance with all applicable codes
and specifications. Basin must be sized to allow a minimum 3
minute lapse time between starts.
(11) The tethered variable level float switches must be free and not
hang up on pump or pit peculiarities. Float switch circuits shall
be intrinsically safe.
(12)
If
a rail system is used, it should be non-sparking. Discharge
elbow
must
be firmly anchored to the bottom of basin. In
fiberglass basin, the bottom will need to be reinforced if the
discharge elbow is used.
(13)
If
a rail system is used, it should be non-sparking. The guide
rails are ¾” schedule 40 pipe for threaded vertical discharge
units and 2” schedule 40 pipe for flanged horizontal discharge
units. Brass, stainless steel or galvanized steel is recommended.
(14) Install ring and cable for lifting pump from pit.
(15) Basin must be clean and free of debris after installation.
