WINTERIZING THE WATER SYSTEM
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. Open the interior access panel under the fridge to access
the back of the Truma water heater and the 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.
NOTE:
It is advised that you follow the Truma
recommendations for decalcification of the water heater.
These instructions can be found on page 17-21 of the Truma
water heater manual
