Eberspächer B1LC compact Operating Instructions Manual - page 12
Heating operation at high altitudes:
up to 1500 m: Unrestricted heating operation,
above 1 500 m: Heating operation is possible during a short
stay (e.g. crossing a mountain pass, taking
a rest). If a longer stay is planned (e.g. winter
camping), the fuel has to be adapted to the
altitude. In this case, please consult the
heater manufacturer for advice.
Elektrics:
Arrange electric cables, switches and control units in the
vehicle in such a way that their correct functioning cannot
be impaired under normal operating conditions.
The pilot light (built into the operation unit) should be within
the field of vision of the driver, or at least be visible to him
without great effort.
When carrying out electric welding work on the vehicle,
disconnect the positive terminal from the battery and earth
it in order to protect the control unit.
Operating unit and Mini-timer
The operating unit (see page 2 for Cat. No.) comprises the
On-Off switch with controller for the heating capacity, a red
light for illumination, and a green operation pilot light. Two
scale discs are supplied with the operating unit.
Scale disc 1 is fitted if operation is exclusively with the
operating unit. The operating unit then serves as an On-
switch and temperature controller.
Scale disc 2 is fitted if a M ini-tim er is used for actuation.
Switch-on is then exclusively with the Mini-timer, and the
temperature is selected with the rotary knob. See wiring
diagram fo r connection.
Remove the protective film before fitting.
Permissible clearance
for operating button
0,5 to max. 1. mm.
The following cable cross-sections must be observed
between battery and heater, in order that the maximum per
missible voltage losses in the cables (0.5 at 12V rated volta
ge and 1 V at 24 V) are not exceeded.
Length + and — < 5 m -*• cross-section 4 mm2
Length + and — 5 to 8 m -> cross-section 6 mm2
If the positive cable is to be connected to the fuse box (e. g.
terminal 30), the vehicle's cable too from the battery to the
fuse box must be included in the calculation of the total line
length, and if necessary redimensioned in accordance with
the above.
Smear plug and earth connections with contact protection
grease outside the vehicle interior.
Temperature control
The >High/Medium/Low/Off< settings are provided for tem
perature control.
A temperature sensor is arranged on the intake side of the
heater, and - in conjunction with the controller of the operat
ing unit - switches the heater to "High", "Medium" or "Low"
or "O ff" depending on intake temperature and controller
setting.
This type of temperature sensor is only suitable for recireu-
lated-air operation (heating air intake from the space being
heated).
If the heater is operated with fresh air, an external tempera
ture sensor (for Cat. No. see page 2) must be fitted in the in
terior and connected according to the wiring diagram. The
sensor must not be attached to uninsulated outer panels, and
must be protected from draughts and direct sunlight. See w i
ring diagram for connection.
