11. STARTING UP THE SYSTEM
The PowerSewer® grinder pump pressure sewer system installation
is now complete and ready for use. The following start-up procedure
should be followed to verify proper system installation and operation.
11.1 Pre-Startup Checklist
Pre-Startup requirements include:
• Verify that all breakers and power supplies are disconnected or
in the “off” position.
• Verify the electrical supply power.
• Verify the locations of all isolation valves and corporation stops on
the property, at the force main connection and in the force main.
• Verify that all isolation valves and corporation stops are
in the “open” position.
• Verify that the redundant check valve is installed where the
lateral line joins the force main.
• Verify that all cables are the proper size and suitable for
direct bury service.
• Verify that all wiring connections match the Wiring Diagram.
• Verify that all cord grips are properly tightened.
WARNING
Hazardous voltage can shock, burn or
cause death Verify the required electrical supply power for specific
grinder pump matches that of the grinder model being used Using the
incorrect voltage or phase can cause fire or damage the pump motor or
cause severe personal injury and will immediately void the warranty
11.2 Flush System
Prior to testing or operating the PowerSewer® system, the inlet piping
should be flushed to force any construction debris into the collection
tank. Remove all of the debris from the collection tank.
NOTICE
Do not use the grinder pump to remove
installation debris Doing so will void the warranty
11.3 Installing Grinder Pump
WARNING
Failure to disconnect and lockout
electrical power before installing the grinder pump can cause shock,
burn or bodily injury, possibly including death
The electrical connection for the grinder pump must be made in the
field. Utilizing a 9/16" wrench or socket, remove the six bolts holding
the tank cover in place. Then using a #2 Phillips head screwdriver,
loosen the four screws securing the cover to the junction box. Inside
will be three direct burial wire nuts for the connection.
Remove the cover to the wet well. Reaching into the wet well access,
you will be able to bring the power cord through strain relief and cord
grip. Then bring the power cord through the cord grip and grommet in
the side of the junction box.
The length of the power cord is 10' long regardless of the size of
the tank. Do not leave extra cord inside of wet well. The cable may
become entangled in the rotating cutters or interfere with the
operation. The cord may be cut in the field or looped in the dry well
around the wet well access opening.
Proper wire stripping technique should be used to ensure that the
insulation of the individual conductor is not cut while removing the
outer jacket of the pump power cable. Remove the outer jacket of the
pump power cable and remove the insulation material. Carefully strip
back 1/2" of insulation off the individual conductors.
WARNING
In stripping the outer jacket, the inner
insulation must not be cut or damaged Damaged insulation can
cause electrical shock, burns, or death and/or damage to the pump
This will void the warranty
Refer to the Wiring Diagram for details. Utilizing the provided wire
nuts ensures that the proper electrical connections are made prior to
power being applied to the system.
Once the wiring is connected, attach the lift handle to the top of the
pump with the provided clevis pin. Then align the stand-off bracket
with the C-Channel guide rail. Carefully lower the pump down the
guide rail until it comes to a rest on the isolated pump support bracket.
NOTICE
Do not drop the pump into the disconnect stop
Severe damage to the pump and/or C-Channel may occur This will
void the warranty
After installing the pump, verify all electrical connections prior to
turning the power on. Tighten the strain relief entry through the dry
well. Then tighten the cord grip into the junction box. Replace the
cover, being sure to align the cover, and tighten the four screws to fit
5 ft-lbs. Do not overtighten the cover screws as they will break or strip.
NOTICE
Failure to make watertight connection in the
junction box may result in corrosion to electrical contact and result in
premature pump failure This will void the warranty
11.4 Open Discharge Valve
Turn the isolation valve extension handle to the “open” position.
The handle will be parallel with the discharge pipe.
The start-up procedure cannot be completed with the isolation
valve in the “closed” position. In some installations, there may be
one or more isolation valves at the force main connection or in the
force main that must be open to complete the start-up procedure.
The isolation valve(s) must remain in the “open” position for
normal system operation.
