Final Tasks - Truma Combi eco Installation Instructions Manual

6 Clamp or crimp ring (not included in scope
of supply)
7 Venting hose, external diameter 7/16 in. (11 mm)
Connecting the cold water line
1. Insert the prepared 1/2 in. CTS cold water
line with adaptor (Fig. 33 – 2) into the elbow
fitting (Fig. 33 – 1) until it fits snugly.
2. Insert the elbow fitting (Fig. 33 – 1) into the
lower connection (cold water supply) of the
water container until it fits snugly.
Connecting the hot water line
1. Insert the prepared 1/2 in. CTS hot water line
with adaptor (Fig. 33 – 5) into the elbow fit-
ting (Fig. 33 – 3) until it fits snugly.
2. Insert the elbow fitting (Fig. 33 – 3) into the
upper connection (hot water outlet) of the
water container until it fits snugly.
Installing a venting hose
1. Drill a hole (Ø 7/16 in. (11 mm)) in the RV's
undercarriage.
2. Slide the venting hose (Fig. 33 – 7) onto
the hose nozzle of the aeration valve
(Fig. 33 – 3a).
3. Angle the venting hose (Fig. 33 – 7) down-
ward, ensuring there are no kinks.
– Minimum radius of curve: 1 1/2 in. (40 mm).
4. Make sure that the venting hose extends
only 0.8 in. (20 mm) beneath the RV's under-
carriage. Cut the end of the hose at a 45-de-
gree angle (Fig. 33).

Final tasks

• Pull on all the water connections to ensure
that they are securely connected.
• Check all water connections for leaks.
– Repair leaks as needed.
– Repeat check for leaks and take any neces-
sary steps to repair the leaks at all water
connections.
Installing the CP plus control panel
Please refer to the installation instructions sup-
plied with the CP plus control panel for further
information on how to install the control panel.
Installing the room temperature
sensor
The room temperature sensor must
be connected, otherwise the Combi furnace will
malfunction.
We recommend installing the room temperature
sensor in the following way to maintain a steady
room temperature:
• Do not subject it to direct heat.
• Install it above the main door.
• Install it on a vertical wall. The room tem-
perature sensor must be completely exposed
to room air.
Diameter 25/64 in. (10 mm)
Fig. 34
1. Drill a hole.
2. Feed the end of the cable with one insulated
connector from the rear through the drill
hole.
3. Connect the connector cable to the sensor.
Polarity is not a concern.
4. Insert the room temperature sensor. Run the
end of the cable with two insulated connec-
tion plugs to the Combi furnace.
If necessary, the connector cable can
be extended using cables (2 x AWG 20
(2 x 0.5 mm²)). The overall length must not ex-
ceed 33 ft (10 m).
