To Rinse the Black Tank:
• With the black tank valve left in the open position open the grey tank valve. This will
allow half of the grey tank liquid to flow into the black tank. Gravity will equalize the vol-
ume in the tanks in a few moments.
• Close the grey valve and turn the pump back on to rinse the black tank. This process may
be repeated to rinse the tank again.
To Empty the Grey Tank:
• With sewer attachment installed open the grey tank valve and turn on the pump.
Grey Water Bypass:
The grey water bypass system allows continuous grey water flow during stays at parks with sewers
at the site. The liquid (grey) waste uses gravity to drain from the tank and bypasses the pump by going
through the bypass hose into the parks sewage service. The bypass hose is the small garden-sized hose
connected at the termination point of the dump valves and "T-s" into the small flexible hose on the out-
let side of the macerator pump.
To Use the Grey Water Bypass:
• With the 3" flexible hose connected at the termination point of the liquid and solid waste
drain valves and the sewer pipe adapter attached to the facilities sewer system, open the
grey tank drain valve.
• Ensure the sewer pipe adapter is in sewer connection.
• Open the grey water bypass valve where the garden hose fits into the bottom of the con-
nector at the termination point on the liquid and solid waste drain.
Troubleshooting:
• For the macerator pump to run the chassis battery disconnect switch in the engine com-
partment needs to be on.
• 12 Volt DC power for the macerator pump comes from the chassis batteries and is protect-
ed with a 20 Amp fuse located on the rear run box at the curb side of the engine compart-
ment R4 Circuit Board.
