Mechanical Installation
Sewage systems require an approved liquid tight sump or receiving tank with an air-tight cover. The tank or
cover shall be connected with vent piping that is sized as required by national and local plumbing codes or
ordinances.
To prevent piping blockages and damage from frozen water, tank installation should be at a sufficient depth
to ensure that all plumbing is below the frost line.
During installation, pump controls shall be configured such that the pump turn off level is 1m (3.3 ft) from the
bottom of the tank.
LEH-Series sewage pumps may be mounted on a guide rail using one of Liberty's GR-Series guide rail
bases, or stand-alone (See Figure A). Pump and guide rail installation shall be in accordance with all
plumbing codes and ordinances and only be performed by qualified personnel. Typical installations consist
of a guide rail mount in a fiberglass, concrete, or polyethylene tank.
GUIDE RAIL INSTALLATION INSTRUCTIONS
LEH-Series Liberty Pumps use either GR22-LE or GR30 Guide Rail Systems (refer to Fig. A)
1. Install the guide rail claw on the pump with the supplied bolts and rubber gasket.
2. For the best seal, apply any standard grease to the hook points of the guide rail claw and to the exposed
face of the pre-applied claw gasket that seals to the guide rail base.
3. Liberty GR-Series guide rail systems contain self-aligning features to ensure the pump seats on the guide
rail base properly. Using the lifting chain, position the guide rail claw over the upper guide rail support.
Begin to lower the pump down the guide rail into the tank.
4. As the pump nears its final position, keep the pump and claw oriented such that the straightening rib self-
aligns the claw with the guide rail base support ears. When the guide rail claw hooks the guide rail base
support ears, the chain will slacken.
5. Grasp the lifting chain and shake the pump to ensure a good seat with the gasket. The pump is now
suspended by the bracket ears. The weight of the pump will compress the gasket against the mating flange
of the guide rail base to create a seal.
6. The lifting chain may be removed from the hoist and hooked near the upper guide rail support.
Explosion and fire hazard. Do not install this pump
in locations classified as hazardous or in explosive
atmospheres as defined by any applicable national
electrical safety code.
Never pull on the power cord or lift pump by power
cord. Doing so could damage the power cord and
create an electrical shock hazard. Only use lifting
chain or cable to lift pump.
