Intended use
The Truma electric antifreeze kit* keeps the
Truma AquaGo™ instant water heater frost-
free to -4 °F (-20 °C) while you are driving or if
there is no gas supply. To operate the Truma
antifreeze kit you need a 12V (minimum 120 W
recommended) power supply from the RV’s on-
board system.
* For AquaGo™ comfort / AquaGo™ comfort plus
The Truma electric antifreeze kit protects
only the water in the Truma AquaGo instant
water heater against freezing. The Truma elec-
tric antifreeze kit will not protect the RV’s entire
water system. Water lines, faucets, water tanks
and the external water valves and the vehicle
must be heated separately.

side wall of the vehicle.
• When walking past or bending over,
make sure that you and others have suf-
ficient distance.
4. Open the latch with your thumb while pulling
the Easy Drain Lever down as far as it will go.
