Warm Air Supply And Circulating Air Return With Outside Assembly; Fitting The Control Panel; Installing The Control Panel With Rotary Switch; Installing The Control Panel With Slide Switch - Truma Trumatic E 4000 Mode D'emploi

The warm air system is designed for each type of vehicle indi-
vidually, 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
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. 4 + 5 (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 diam-
eter of 100 mm. Apply sealing
agent to flange of both connec-
tor 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 vehi-
cle 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 con-
nect 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 recircu-
lating 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 protec-
tion 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 indi-
vidually, on a modular basis. There is an extensive accessories
program available (refer to brochure).

Fitting the control panel

)
2
When using control panels which are specific to the
vehicle or manufacturer, the electrical connection must
be effected in accordance with Truma interface specifications.
Any modification made to the Truma components pertaining
to this will lead to the cancellation of the guarantee and to the
exclusion of any claims for liability. The installer (manufactur-
er) is responsible for providing operating instructions for the
user as well as for the labelling of the control panels!
When selecting the location, take note that the control panels
must not be subjected to any direct radiant heat. Length of
the connection cable 4 m or 10 m.
If installation is only possible behind curtains or in similar
locations with temperature fluctuations, a remote sensor for
the ambient temperature must be used (Accessories).

Installing the control panel with rotary switch

If flush mounting is not possible, Truma will supply an
on-surface frame (1 – part no. 40000-52600) as an ac-
cessory on request.
Drill a hole 55 mm in diameter.
Plug the control panel cable (2) into the control panel (3) and
then fit the rear cover cap (4) as a stress-relieving device.
Push the cable through to the rear and lay it to the electronic
control unit.
Secure the control panel with four screws (5) and fit the cover
frame (6) in place.
