•
• Push and hold the macerator button until tank is empty.
•
• After the black water tank is empty, close the black water tank valve by pushing in on the handle.
•
• Open the grey water tank gate valve by pulling the grey handle out.
•
• Again, push and hold the macerator button until the tank is emply.
•
• After the grey water tank is empty, close the gray tank valve by pushing it back in to the original position.
Always dump the black tank first and the gray tank second. The graywater will help flush any remaining solids from
the dump hose.
•
• Use the dumpsite rinse hose to clean the end of the hose.
•
• Replace the hose in its compartment and close the cover.
•
• Add about ½ gallon of fresh water to the black tank. While you`re doing this, add a packet of black holding tank chemicals
to the tank.
Do not toss the packet into the toilet, even if it claims to be `dissolvable`. It may not be dissolvable enough for the
wastewater system. Tear open the packet and pour the contents into the toilet, and dispose of the packet in the trash.
The contents of the powder packets can be irritating to your eyes and nose, so hold the packet low to the bowl and try to
pour directly into the tank.
