Shutdown; Switching Off The Furnace; Draining The Water Container - Truma Combi eco Operating Instructions Manual

– There may be a variation between the tem-
perature delivered from the Combi furnace
and the temperature at the faucet due to
water conditions or the length of pipe from
the Combi furnace.
– The presence of a flow restrictor in the hot
water line may limit the water flow.
6. If using hot water:
– Use the CP plus control panel to select the
desired water temperature level.
– To obtain the desired water temperature at
the faucet or in the shower, mix cold and
hot water.
– Make sure that the water temperature has
stabilized before any person or animal en-
ters the shower.
Scalding injuries caused by hot air!
Ventilation air can reach 250 ºF (121 ºC) at the
warm air outlet and it can cause severe burns
or scalding and in extreme cases even death.
• Always check the air temperature before
varying the air throttle position (Fig. 1 – H).
7. If using hot air:
– Use the CP plus control panel to set the de-
sired room temperature.

Shutdown

Switching off the furnace

1. Switch off the Combi furnace using the
CP plus control panel. Due to internal pro-
cesses, it may take some time until the fur-
nace is completely shut down.
2. If the Combi furnace and any other gas-pow-
ered device is not needed anymore, turn off
the LP gas supply.
3. Switch off the Combi furnace's electrical
power supply.
If you intend to put the RV into storage
or if you switch off the Combi furnace
during freezing temperatures, refer to
"Winterizing" on page 14.

Draining the water container

Damage to the Combi furnace
caused by freezing!
• The Combi furnace does not have a frost-pro-
tection function. The water container must be
drained if the recreational vehicle (RV) will not
be used whenever there is a risk of frost.
No warranty claims for frost damage are
accepted.
To make sure that all water drains prop-
erly from the water container, place
a big enough vessel underneath the
drainage socket of the pressure relief/
drain valve (> 2.64 gallons (10 liters)).
1. Use the main switch or pump switch to
switch off the power to the water-pump
assembly.
2. Turn off or disconnect the city water connec-
tion, if present.
3. Open all water release points, e.g. cold and
hot water faucets, showers, toilets.
4. Open the pressure relief/drain valve (refer
to "Opening the Truma pressure relief/drain
valve" on page 11).
The water container will drain via the drainage
socket of the pressure relief/drain valve.
