WARNING: Risk of electrical shock or electrocution.
Failure to heed the warnings may result in serious
injury, death, or fire hazard. The installer must
disconnect all electrical sources prior to installation.
Only qualified personnel may install this system.
NFPA 70/National Electric Code (NEC) or local codes
must be followed. System must be properly grounded
according to NEC or local codes.
CAUTION: All local wiring codes must be observed.
Consult the local inspector before installation to avoid
costly delays that can occur due to rejection after
the job is finished. Only qualified electricians should
make the installation. Complete wiring diagrams are
included for use in making the installation. All wires
should be checked for shorts to ground with an
ohmmeter or Megger after the connections are made.
This is important, as one grounded wire can cause
considerable trouble.
Pump Installation
Follow STEP pump installation instructions for safe
and correct pump operation.
Float Tree Assembly
The float tree assembly is shipped disassembled
from the factory. The floats will be assembled to the
float clips and pre-set to the 2.5" float tether length
as required for proper operation. The float clips must
be attached to the float tree in the proper positions in
order to meet necessary reserve capacity, pump on
level, pump off level, alarm level, and to meet local
codes.
The floats must be staggered 20 degrees as shown in
figure 3 to ensure proper operation.
The float tether length must be 2.5" as shown in figure
3 to avoid float failure.
Filter Installation
Lower the filter assembly into the housing until it
bottoms out. Turn the PVC latch to lock the filter
in place (The filter must be installed in the housing
before the pump vault assembly is installed).
Junction Box Connections (when used)
Step 1: Ensure power source is off or disconnected.
Step 2: Install the junction box in the riser in a location
which will not interfere with the removal of the filter.
Step 3: Install a conduit seal outside the basin to
prevent surface water from entering the junction box.
Step 4: Push pump power and float cords through
cord grips in the junction box and tighten the cord
grips. To prevent corrosion or electrical short, plug
any unused holes.
Step 5: Remove junction box cover and make all
connections inside junction box to all incoming alarm/
control panel wires.
Electrical Connections
Note: Failure to use a manufacturer approved
alarm or control panel voids the pump warranty and
guarantee.
IMPORTANT: Properly connect the panel ground
wire to a grounding rod. Improper grounding voids
warranty.
Panel Wiring
Ensure power source is off or disconnected.
Follow the alarm/control panel installation instructions
as provided by the manufacturer.
Start-up Checks
Before placing the pump into operation, verify the
following:
• Septic tank or pump chamber installed according to
local regulations
• Septic tank or pump chamber is watertight
• Access riser and cover are installed according to
manufacturer's instructions and local regulations
• Pump vault is installed according to instructions
• Float tree is installed and wired into control panel
• Float switches are free to move within vault housing
• All electrical connections are watertight and
conform to the National Electric Code (NEC) and
state and local regulations
Step 1: Run clean water into the septic tank or pump
chamber.
Step 2: Open the shut-off valve.
Step 3: Turn the H-O-A switch to the Off position and
turn on the main breaker.
Step 4: Start the pump by turning the H-O-A switch to
the Hand or Manual position.
