hose can be manually pulled out� Secure the hose
at the disposal facility inlet using the threaded or

the hose from the inlet if the hose is not secured
properly.

Water tank first and the Gray Water tank second,

the solids in the tank�
4� When black tank is empty, turn off the pump�

pump� Run until just before the pump runs dry� Any
trickle of gray water left will remain in discharge
hose behind drip proof valve and is typical�

seconds could damage the pump�

adaptor from the dump station inlet� Retract the
hose into the hose reel by holding the switch in
the "retract" position� Be sure to guide the hose
back and forth onto the reel evenly� Close the
