INSTALLATION INSTRUCTION MANUAL
TANK DRAWDOWN
Tools and Hardware Required
A Philips screwdriver is required to remove the SubDrive access panel. A crimp tool
may be required for the ¼" quick connects that will attach the aux device to the
relay interface.
For the SubDrive Nema 4 units, excluding the SubDrive300, an Auxiliary Relay
Board is required. An Auxiliary Relay Board kit can be purchased with order
number 225755901.
Serious or fatal electric shock may result from failure to remove electrical power from
the SubDrive prior to installing the relay interface. Disconnect power before working on
the system. Capacitors inside the SubDrive can still hold a lethal voltage for some time
after power has been removed, so allow 10 minutes after removing supply power for
dangerous internal voltage to discharge.
ATTENTION
This equipment is intended for installation only by technically qualified personnel. Failure
to install it in compliance with national and local electrical codes and within Franklin
Electric’s recommendations may result in electrical shock or fire hazard, unsatisfactory
performance, and equipment failure.

Purpose
The tank drawdown kit uses the system run relay and an additional pressure sensor
to allow the use of water stored in the tank during low flow demands.
This setup will allow the drive to control pressure using the regulating sensor to
maintain constant pressure when operating normally. Once the system shuts off,
it will use the stored water in the tank until the pressure drops to the secondary
sensor pressure setting. At that time, the drive will start and regulate to the
regulating pressure sensor pressure setting.
