BLACK WATER TANK
The OP15 black water tank is located towards the front of the trailer on the lower edge of the
driver’s side. It can be identified by the black tank drain valve. The capacity of the tank is 10 gallons
and the fill level can also be monitored using the gauge on the main control panel.
EMPTYING THE TANK
We recommend emptying your black tank when it is at least 1/2 to 3/4 full and after every camping trip.
Emptying your tank sooner may result in solid waste being left behind in your tank; a fuller tank allows
more opportunity for breakdown of solid waste. All waste from the OP15 toilet is collected in the black
tank so please take caution when emptying to avoid contact with waste which can carry harmful
bacteria. The black tank must ONLY be disposed of in designated dump stations. At the rear of the
trailer is a holding tube for the black tank drain hose.
Located on each potable water tank you will find a draining valve at the lowest point of the tank.
When packing away the OP15 complete the following process to drain the system of any excess water.
A. Switch off the pump on the main control panel
B. Open the faucet & allow the excess water in the pipe to drain
C. Close the faucet once all of the water has drained.
D. Disconnect either side of the quick connect
E. Ensure the sink is emptied and that the waste water drain hose is empty before folding it back into the kitchen. Please refer to the steps in the care and
maintenance section of this user manual for more information on draining and preparing your tanks for storage.
A. Remove the black tank hose from the storage tube by twisting the cap off
B. Connect the drain hose to the drain valve by twisting on to receiver hooks
C. Ensure the other end of the drain hose is directed into the appropriate dump point.
D. To empty, pull the valve to open.
E. Leave the valve open until you can no longer hear liquid waste draining then close the valve completely. Close the valve at this point
BLACK TANK TIPS
You can also use Formaldehyde-free black tank treatments such as the Camco TST Drop-ins to help breakdown waste and prevent odors. If you are on-site
camping and connecting to a campground sewer we recommend keeping the tanks drain valve closed until you need to drain to assisting in purging the tank
of solid waste. Please see the ‘Bathroom’ section of this manual for more infor-mation on using your toilet.
WARNING
Do NOT leave waste in your tank during storage. Always remember to close the drain valve after draining the black tank and before removing the drain
hose. Your drain hose should also be regularly cleaned and sanitized. Do NOT use bleach to clean your black water tank. Please see the care & mainte-
nance section for further details on properly cleaning & sanitizing your black tank.
