DUMPING SYSTEM (Optional)
The holding tank management system is a closed loop system designed to empty the tanks, rinse
the black tank with water from the grey tank to eliminate clean water usage, transfer grey water from
the grey tank to the black tank when dry camping to maximize the capacity of the tanks, and reduce
exposure to unsanitary conditions.
The system comes with a 3" inlet hose with sewer pipe adapter, a 12 gallon per minute macerator
pump, a grey water bypass hose with on-off valve, drip cap, a 10' attached hose and a 12' spare hose.
To Empty the Black Tank:
• Ensure the 3" flexible hose from the
macerator pump to the termination
point on the dump connection is
secure.
• Remove drip cap at bottom of sewer
pipe adapter.
• Insert adapter into sewer connection.
• Open the solid waste drain valve at
the plumbing service center by
pulling outward. Turn on the pump
using the switch on the service cen-
ter panel.
• When the black tank is empty, turn
off the pump and leave the black
tank valve open.
