Installation: Pump Location - Franklin Electric INLINE Serie Mode D'emploi

INSTALLATION: PUMP LOCATION

NOTICE
Read and follow all instructions.
WARNING
Liquid-tight cables or flexible conduit and
fittings must be used to maintain Type 4 rating.
Installation Procedure: Pump
Choose a clean, well-ventilated location that provides protection from freezing,
flooding, and excessive heat. Provide access for service and draining of the device
and pump.
The device can be installed directly on the pump discharge or between the pump
discharge and first water outlet. For proper operation, Inline Controls must be
installed vertically, as indicated by the text on the product labeling of the control
unit. Ensure the flow direction arrow is facing upwards (Figure 1).
Auxillary Pressurized Bladder Tank Air Charge Setting:
Generally an auxillary pressurized bladder tank is not required, but specific
application driven conditions can facilitate the need for one. For example, consider
a system where the water flow starts/stops on short intervals. If the system requires
the motor to start beyond the manufacturer's recommended number of starts per
day, a bladder tank can provide additional water supply, lengthening the total time
between motor starts (for Franklin Electric 4" Submersible Motors see Table 1). For
non-submerged, centrifugal pump/motors, regular starts more frequent than 10 per
minute would benefit from utilizing a bladder tank.
Installation Consideration for 2-Wire 4" Submersible Biac Start Motors:
It may be necessary to use a small bladder tank with Biac Start Submersible motors.
The tank should be sized to provide approximately 5 seconds of pressurized water
allowing the biac switch to cool and reset prior to the next pump start.
