Thermo 90 S / Thermo 90 ST Installation
4. Installation
IMPORTANT!
The water heater must be installed outside
the passenger cabin.
The requirements of the latest version of
“Hazmat” must also be observed for the
installation of the heater into vehicles used
to transport hazardous substances.
4.1 Installation site / Installation position
The heater must be installed in as low a position as
possible to allow the heater and circulating pump to be
bled automatically. This is particularly important as the
circulating pump is not self-priming.
The installation must be performed in accordance with
the installation instructions provided in this manual.
NOTE:
If the vehicle manufacturer has issued specific installation
instructions, they must be followed.
4.2 To install the heater
The heater must be secured with at least three M8
screws. The screws must be tightened with a torque of
18 Nm. (13.3 lb-ft).
4.3 Model plate
The model plate must be positioned so that it cannot be
damaged and must be clearly legible when the heater is
installed (otherwise a duplicate model plate must be
used).
Inapplicable years must be erased from the model plate.
4.4 CE mark
The Thermo 90 S / Thermo 90 ST water heater carries the
CE mark since it complies with the regulations in force.
The heater satisfies the requirements of class A. As a
result, the following supplement applies:
This is a class A device. This device
may induce radio interference in
residential areas; in this case, the
owner may be required to
undertake appropriate measures.
As a rule, installation in the engine compartment
represents sufficient screening. Please contact the
Webasto hotline in the event that radio interference
occurs nevertheless.
