Connecting The Exhaust Double Duct To The Device; Circulated Air Intake; Warm Air Distribution - Truma Combi E CP plus ready Einbauanweisung

Connecting the exhaust double duct to the
device
Compress exhaust duct (1) at its beginning so that the coils
lie next to each other. Slide clip (4 – claws toward unit) over
exhaust duct (1). Slide clip (7) onto combustion air infeed (5).
Slide exhaust duct (1) all the way onto connection (3). Slide
exhaust duct clip (4) as far as it will go (end position must be
between claws of clip) and screw in place. Slide combustion
air intake duct (5) onto connection (6) and secure with clip (7).

Circulated air intake

The circulated air is drawn in by the unit. This must have one
large or several small openings with a total area of at least
150 cm² between the living compartment (not the rear stor-
age space) and the installation compartment.

The circulated air inlets must be arranged such that exhaust
from the vehicle engine or the heater cannot be drawn in
under normal operating conditions. Structural measures must
be taken in order to ensure that the heating air that is led into
the interior of the vehicle cannot be contaminated.

Warm air distribution

Most of the warm air is led into the floor area of the living
compartment via flexible ducts.
The 4 connections on the unit are designed for the 65 mm
diameter ÜR duct (part no. 40230-00). Use only pressure-
safe ducts in compliance with Truma quality requirements.
Other ducts that do not meet our quality standard (particularly
crown pressure resistance, duct diameter and number of
grooves) must not be used.
If the warm air duct has to be subjected to a considerable
amount of bending immediately behind the warm air outlet
of the unit in confined spaces, we recommend the use of
the BGC 90° elbow (part no. 34091-01). This elbow makes
it possible to connect a ÜR warm air duct with a diameter
of 65 mm or a VR warm air duct with a diameter of 72 mm.
Fig. 11
With a duct length of less than 2 m the air outlet must not be
installed higher than the warm air duct connection. With a
duct length of less than 50 cm, the duct must create a siphon
between the connection and the outlet.

These measures prevent undesirable heating of the vehicle
due to convection (cowl effect) during operation in summer.
The ducts for warm air distribution must be firmly
inserted into the connections. A clip is attached to each
connection to provide a more secure grip.
For optimum warm air distribution, Truma always recommends
using the 4 warm air outlets of the heater. If only three warm
air outlets are needed, one of the lower warm air outlets must
be sealed with a blank cover VD (part no. 34310-01). The
blank cover must be firmly pushed into the moulded part of
the heater until it audibly engages and is firmly seated. Check
for firm seating.
If four warm air outlets are being used, a closable end
outlet EN may be installed in one warm air branch. If
there are only 3 warm air outlets, it must be ensured that if a
closable end outlet is being used (e.g. bathroom) a second
non-closable nozzle must be installed in the warm air branch.
In order to prevent heat accumulation when using the
Combi D 6(E), all 4 warm air connections must be
attached. The cross-section of the warm air ducts must not be
reduced by duct connections or the like. If a closable EN end
outlet is installed in a warm air branch of the Combi D 6(E)
(e.g. in the bathroom), a second non-closable nozzle should
be installed in this warm air branch.
The warm air system is individually designed for each vehicle
model using a modular principle. A wide range of accessories
is available for this purpose.
