WINTERIZING THE WATER SYSTEMS
1. Drain the fresh water tank by opening the drain tap on the
fresh water tank.
2. Drain and flush the black and gray water holding tanks.
3. To access the back of the Truma water heater and the
bypass valves, open the interior access panel under the
fridge to access the back of the Truma water heater and
bypass valves.
4. Turn the bypass valves on the top red line, bottom blue line
and the white center line to the closed position. (The handle
is closed when it is turned 90 degrees to the water line.)
Open the valve that is located where the blue line coming up
from the bottom and the red line coming down from the top
are connected.
5. Open the exterior door to the Truma water heater. Turn the
electrical switch to the OFF position. Open the water heater
drain by lifting the black latch on the top of the yellow easy
drain lever. Lower the drain lever until the water filter opens.
6. With the filter removed, inspect and clean the water filter.
Inspect the “O” rings on the filter as found on page 16 of the
Truma water heater manual. Remove the filter for winter.
*Please follow the Truma recommendations for decalcification of
the water heater. These instructions can be found on page 16 of
the Truma water heater manual.
