installation in Class
I
, 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 I , Division 1, Group C & D environments,
to prevent moisture and gases from entering the control panel.
(6) When check valve is installed , drill a 3/16" (4 mm) 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.

(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 fiber -
glass 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 3/4” schedule 40 pipe for threaded vertical discharge
units and 2” schedule 40 pipe for flanged horizontal discharge
