Trumatic E 4000 / E 4000 A - Ostsee Campingpartner

Fastening the heating appliance
Inside installation with wall cowl or roof cowl
Depending on the installation site, bolt the heating appliance
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).
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 nonsealable
(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 (especially
as far as the first air outlet in the case of the E 4000) must be
protected from contact by cladding with a duct insulator (such
as Truma l 80). Secure all duct connections with self-tapping
screws. Fasten ducts with clamps.
The warm air system is designed for each type of vehicle individually,
on a modular basis. There is an extensive accessories
program available (refer to brochure). Diagrams with optimum
installation suggestions for warm air systems in all of the most
popular motor home models can be requested free of charge
via the Truma service centre.

Circulating air return
The circulating air (U) is sucked directly back into the appliance.
If the heating appliance is installed in a stowage compartment
or similar, make an appropriately sized opening (approx, 200 cm 2 )
for circulating air feedback.
Do not block air ducts to heating appliance!
Warm air supply and circulating air return
with outside assembly
Refer to installation variants Fig. 3 + 4 (Page 2).
The warm air duct and recirculating air duct between the
heater and the vehicle – especially in the area prone to stone
demage – must be made from flexible LF air ducting or, in the
protection zone, from LI air ducting (106 mm in diameter).
A protective casing over the entire heater system protects it
against damage and weather conditions and simultaneously
serves as insulation.
Drill two openings with a diameter
of 100 mm. Apply sealing agent
to flange of both connector fittings
(41) and bolt to the openings
on the outside. Place the grid (47)
in the recirculating air duct between
the suction connection fitting and
the vehicle wall. Thread LFS wire
clamps (42) onto the air ducts (43).
Slide the air ducts over the heater
connection fittings (44) and the connector
fittings (41) and fasten them
with the LFS wire clamps (42). Seal
the joints with silicon paste.
Seal hollow double walls around the
air duct by putting two rolled sheet
metal strips (45) or lengths of pipe
between 97 an 100 mm in diameter
into the openings.
The warm air can be extended
inside the vehicle using LI air duct
(diameter 106 mm). To connect the
air duct, fasten another connection
fitting (41) into the opening.
The two connector fittings can be
bolted together through the wall.
If you wish the warm air to be diffused inside the vehicle, an
air diffuser (46) can be fitted over the warm air duct (W) with
4 bolts.
Do not close off or restrict the opening for the recirculating
air duct!
The air diffuser (46) has 2 connections for VR 72 duct (72 mm
diameter), neither of which must be closed off. The protective
metal sheet supplied (48) acts as a heat shield and must be
securely fastened over the air diffuser (46). Stowage protection
can be provided in the form of another protective metal
sheet (49) fastened over the opening for the recirculating air
duct (Accessory, part no. 39010-11500).
The warm air system is designed for each type of vehicle individually,
on a modular basis. There is an extensive accessories
program available (refer to brochure). Diagrams with optimum
