Installation
ATTENTION!
– The statutory regulations governing installation on pages 33
and 34 must be adhered.
– If the water heater is to be operated in a separately installed hea-
ting system, prior to installation an installation planning report
must always besubmitted to Spheros for approval. If this appro-
val is not obtained, all warranty and liability claims will be void.
The water heater has been designed, tested and approved for
specific bus requirements.
– To the temperature sensor cable no mechanical load must be
applied (e.g. carry the heater with it).
– Heater and circulating pump shall be always installed in such a
way that a negative impact by road dirt, splashing water, ex-
haust gases or other harmful influences is excluded.
– The component disassembly (drive motor, fuel pump, solenoid
valve, control device and temeperature sensor) is not permitted
and will lead to the loss of all liability claims.

Installation location
Consider the installation situation of the relevant vehicle type.
The heater and circulating pump are integrated into the cooling system
(or in a separate heating system).
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.
If it is not possible to install the heater in the vehicle’s engine bay it may
be installed in a sealed box. The installation box must have sufficient
external ventilation to ensure that the maximum temperature of 85°C is
not exceeded in the box.
If the expected ambient temperature exceeds permanent 65°C, it is
recommended to install the opening of the air intake line in an area with
lower temperature. Consider the space required for servicing accessi-
bility (for example for removing the combustion chamber, see Figure 1)
when installing the heater.
