Double Duct Connection To The Heating Appliance; Under-Floor Assembly With Wall Cowl Kit; Fastening The Heating Appliance; Outside Assembly With Cowl Pipes - Truma Trumatic E 4000 Mode D'emploi

If the roof cowl is relatively thick, first connect the exhaust
gas double duct from the outside onto the cowl. Slide the rub-
ber seal (22) and clamp (4) onto the inner cowl section (23).
First compress the exhaust duct (1) so that the coil windings
are pressed against each other, then slide over the O-ring onto
the connection fitting (24). Engage the clamp (4) and screw
tight.
Slide the air intake duct (5) onto the serrated connection fit-
ting and secure with the black screw (25).
Fasten the cowl section (23) with 6 bolts (26). Mount cowl
roof (27) and secure using 2 bolts (28).
The exhaust vents in the cowl roof must face at right-
angles to the direction of travel.
Always keep the cap (29) on when the heater is not operating.
Double duct connection to the heating
appliance
Press end of exhaust duct (1) together so that winding
touches winding. Slide clamp (4) over exhaust duct (1). Pass
the exhaust duct (1) via the O-ring and fit it to the exhaust
coupling (17). Engage the exhaust duct tightener (4) onto the
exhaust coupling (17) and secure. Take the connection
fitting (19) with the wide side over the exhaust duct and slide
it firmly onto the air connection fitting (6) on the heating unit.
Line up the opening in the connection fitting (19) with the
drain (18). Screw in and tighten connection fitting (20).
Slide the air intake duct (5) firmly onto the connection
fitting (19) and fasten with duct clamp (7).
Drill a 10 mm diameter opening in the vehicle floor for the
condensate hose (21). Fasten the condensate hose onto the
connection fitting (20) and pass it through the opening.
Due to the risk of frost in winter, the hose should not
project more than 2 cm below the vehicle floor!

Under-floor assembly with wall cowl kit

Refer to installation variant Fig. 5 (page 2).
Cowls must always be fitted to prevent any waste gases en-
tering the inside of the vehicle. The waste gas must always be
guided to at least a side wall (see "Choice of location").

Fastening the heating appliance

Assemble with the aid of the
asembly mount. Fasten both
mounts (36) securely and firm-
ly to the vehicle with through
bolts not less than M5 in size.
Fasten the U-beam (37) to the
outside of the heater with the
bolts supplied (38). Fasten the
heater with 4 M6 x 10 bolts
(39) and self-locking nuts. Fas-
ten two protective caps (40) to
the outside of the vehicle.
In order to drain condensation water, drill a hole 8 mm in di-
ameter at the lowest point in the heater casing some 20 mm
from the edge. Ensure that the drill does not penetrate more
than 10 mm in order to prevent damage to any internal com-
ponents. Insert the rubber grommet (d) supplied (it extends
about 4 cm downwards).

Outside assembly with cowl pipes

See installation variant Picture 3 (page 2) and the Truma as-
sembly instructions "Additional truck heating systems" and
"Trunk compartment heating system E 4000 A".
Fastening the heating appliance
Inside installation with wall cowl or roof cowl
Depending on the installation site, bolt the heating appli-
ance securely with the fastening straps (a) or angle pieces (b)
supplied.

Warm air distribution and circulating air
return with interior installation
Warm air distribution
Warm air suction apertures must be arranged in such a way
that no exhaust gases from the engine or the heating device
can be drawn in. It must be ensured by means of construction
design that the heating air introduced into the vehicle is not
polluted (e.g. by oil vapour). This is achieved, for example,
with air heaters with circulating air operation, both for interior
installations and for external installations. (In heaters with
fresh air operation the fresh air is not to come from the engine
compartment, from the vicinity of the exhaust or the exhaust
outlet of the heater.)
The warm air (W) is expelled from 2 vents, either directly or
via a warm air duct VR 72 (diameter 72 mm).
Fig. 21
Fig. 19 From the appliance to the first air outlet install only VR 72
duct (72 mm diameter) with a maximum length of approx.
1.5 m. To prevent overheating, the first air outlet must be
non-sealable (swivelling vent SCW 2, end support EN-O). ÜR
duct 65 mm diameter) can also be laid after the first air outlet.
Hot air ducts whose surface temperature exceeds 80 °C (es-
pecially as far as the first air outlet in the case of the E 4000)
must be protected from contact by cladding with a duct in-
sulator (such as Truma l 80). Secure all duct connections with
self-tapping screws. Fasten ducts with clamps.
