WARNING: When using this device, always exercise basic safety precautions, including the following:
• Read all instructions before installation or use.
• Never connect this device to any electrical circuit with other than 2 or 24 volt Direct Current or exceed
the amperage draw specified.
• Never install the control panel or the control module in an atmosphere with potentially flammable or explo-
sive vapors.
• this product is not to be installed in shower facilities.
• Never install the control module below the water line.
• Provides four holding tank level indication lights for Empty, Low, mid, and Full levels. One level light is always
on to confirm that electrical power is applied.
• Includes keyed selector switch and “Discharge Pump On” light. An optional “Check Seacock” light is available
to use in conjunction with a seacock interlock switch.
• Prevents accidental overboard discharge in restricted waters when control switch is turned to “Off” position.
• Simplifies plumbing by eliminating wye valves, seacocks, and vented loops for multiple toilet installations.
• Will eliminate stagnating sewage trapped in interconnecting hoses by wye valve operation.
• For use with a t-series discharge pump, tankWatch ® 4 level indicator cap and optional seacock interlock
system.
• 2 and 24 VDC models available.
• Key Switch Configuration 1 – Automatic Start–Automatic Shut-off Mode and Manual Mode:

two different modes, automatic or manual, for holding tank discharge pump control.
 Automatically discharges sewage directly overboard in unrestricted waters while in the “Automatic” mode.
 In the “Automatic” mode, the Mid level float will activate the discharge pump. The pump will then run until
the Low level switch is deactivated.
 The Full level float will turn on the discharge pump if the Mid level float fails.
 the “Automatic” mode will automatically maintain holding tank level between the Low and mid level.
 the “manual” mode provides direct discharge pump control regardless of the level of the holding tank.
• Key Switch Configuration 2 – Manual Start–Automatic Shut-off:

Provides a manual start and an automatic shut-off of the discharge pump.
 Key switch must be turned to the momentary Start position to activate the discharge pump. If the key
switch is then left in the Auto Off position, the discharge pump will shut off automatically when the Low
float is deactivated.
 Holding the key switch in the start position will activate the pump regardless of the level of the holding
tank.
Some fine-tuning of the float switch locations may be necessary to obtain proper operation of the unit.
NOtE: Keep in mind that once you enter a No Discharge Zone, the tankmanager must be switched to the “Off”
position and the key removed to prevent illegally discharging your holding tank. the United States Coast Guard
will allow a key-operated switch as a means to secure the overboard discharge pump system instead of securing
it with a padlock or wire tie.
