Inlet
Connect the inlet line to the inlet hub per engineer’s
specifications.
Vent
The fiberglass basin provided with the system must be completely
sealed and properly vented per local health and plumbing code
requirements. If the system is to be vented through the inlet to an
existing building vent stack, there must be no traps between the
system inlet and the nearest building vent stack connection
(option 1). If this is not possible or desirable per the application, a
standalone vent can be installed in tank side (option 2) or a vent
flange or grommet can be installed in a hole cut into the cover
(option 3).

LEPS GR-Series Guide Rail System
The optional GR20, GR3 or GR4 quick-disconnect assembly guide
rail system supplied with the LEPS is designed to allow easy
installation and removal of the pump. When installed correctly, it
seals and provides a means to lift the pump without disconnecting
any of the discharge piping. Ensure installation is completed as
shown.
Hazardous location guide rail systems are available These “NS”
models (GR20NS, GR3NS, GR4NS) have identical performance to
the GR-Series models shown, except they have a bronze
(non-sparking) claw.
