Truma Combi Hot Water & Heang System
The OP15 comes with the Truma combi eco hot water & heang system installed. This system is
run o of your 12v power and propane gas supply. The system will provide hot water for your
shower, bathroom and kitchen sink as well as forced hot air into the trailer.
We strongly recommend that you read the Truma Combi System manual that is provided with
your trailer thoroughly before use for full instrucon on how to operate and store/winterize
this appliance. Failure to follow the instrucons in the Truma product user manual may result in serious injury or death. Damage
caused by failure to follow the instrucons will not be covered under warranty. In the event that you cannot nd the manual,
please visit www.truma.net/heang-systems/truma-combi-eco for a digital copy of the user manual.
The Truma system is installed in the exterior lockable compartment on the driver’s side of the trailer. To turn the Truma Combi
system on ensure your power and propane are both turned on. Use the Truma control panel located above the 12v TV on the side
of the wardrobe to set the desired temperature. The Truma system can be used to provide either hot water only, forced hot air
only or both concurrently. Please note however that using both the water heater and the forced hot air system at the same me
will reduce the eciency of both systems and cause the water to take longer to heat up.
Heater: Ducts for the forced hot air system can be found under the main OP15
control on the toe-kicker panel. There are three circular outlet vents to exit
hot air and one rectangular vent for return air inlet.
Water Heater: The Truma has a 2.64gl holding tank capacity and uses water
pumped directly from your potable water tank. The water will take
approximately 20-25 minutes to reach temperature and will supply both sinks
and the shower.
WARNING! Please keep all interior vents (air intake and exit) free of obstrucon at all mes. You must also keep the exhaust vent on
the exterior front of the trailer free of obstrucon too.
