Place the Break Away Fitting (BAF) in position. Temporarily
secure the guide rails in the upper mounting brackets and
locate the base on the bottom of the wet well. Level the base
with grout and/or shims. Install the intermediate support
brackets, if required. Make sure the rails are in a true vertical
position so the pump will clear the access opening and will slide
freely down the rails into place on the discharge stationary
fitting. Once the rails are in proper alignment, bolt the base into
the floor of the station and connect the discharge pipe to the
elbow.
Connect the movable portion and other supplied fittings of the
BAF onto the pump and lower into wet well. See the Break
Away Fitting manual for more information.

C-3) Liquid Level Controls:

The level controls are to be supported by a mounting bracket
that is attached to the sump wall, cover or junction box. Cord
grips are used to hold the cords in place on the mounting
bracket. The control level can be changed by loosening the grip
and adjusting the cord length as per the plans and
specifications. Be certain that the level controls cannot hang
up or foul in it’s swing and that the pump is completely
submerged when the level control is in the "Off" mode.

C-4) Electrical Connections:

C-4.1) Power Cable:

The cord assembly mounted to the pump must not be modified
in any way except for shortening to a specific application. Any
splice between the pump and the control panel must be made
in accordance with all applicable electric codes. It is
recommended that a junction box, if used, be mounted outside
the sump or be of at least Nema 4 (EEMAC-4) construction if
located within the wet well.

Do not use the power cable to lift

pump.

NOTE: THE WHITE WIRE IS NOT A NEUTRAL OR

GROUND LEAD, BUT A POWER CARRYING CONDUCTOR.

C-4.2) Control Cable:

Do not use the control cable to

lift pump.

NOTE: THE WHITE WIRE IS NOT A NEUTRAL OR

GROUND LEAD, BUT A POWER CARRYING CONDUCTOR.

C-4.3) Overload Protection :

C-4.3-1) Three Phase (Optional)-

The normally closed (N/C)

thermal sensor is embedded in the motor windings and will
detect excessive heat in the event an overload condition
occurs. The thermal sensor will trip when the windings become
too hot and will automatically reset itself when the pump motor
cools to a safe temperature. It is recommended that the thermal

sensor be connected in series to an alarm device to alert the
operator of an overload condition, and/or the motor starter coil
to stop the pump. In the event of an overload, the source of this
condition should be determined and rectified immediately.

DO NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD
CONDITION OCCURS !

C-4.3-2) Single Phase -

The type of in-winding overload

protector used is referred to as an inherent overheating
protector and operates on the combined effect of temperature
and current. This means that the overload protector will trip out
and shut the pump off if the windings become too hot, or the
load current passing through them becomes too high. It will
then automatically reset and start the pump up after the motor
cools to a safe temperature. In the event of an overload, the
source of this condition should be determined and rectified
immediately.

DO NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD
CONDITION OCCURS !

If current through the temperature sensor exceeds the values
listed, an intermediate control circuit relay must be used to
reduce the current or the sensor will not work properly.
