Initial start-up
CAUTION!
It is mandatory to read through the operating and maintenance in-
structions before starting the heater.
The safety precautions given in the operating and maintenance in-
structions must be considered!
The heaters Thermo E 200 and Thermo E 320 are adjusted in the
factory and can be used unlimited without a change of the CO
ment up to an altitude of 1500 m above MSL and up to 2000 m above
MSL if that is a short stay in such conditions (pass crossing, break).
In case of a permanent heater operation above 1500m the CO
should be readjusted, due to a negative change of the exhaust gas
values in result of the decreased air density.
It is also recommended to adjust the CO
nical data (see table on page 62) if combustion air supply or exhaust gas
applications are used.
After heater installation, bleed the water system and the fuel supply
system carefully. Follow the appropriate instructions provided by the
vehicle manufacturer. Verify the fuel supplied to the heater is bubble-
free.
Before starting the heater for the first time, the bleeding of the fuel
supply line and the fuel filter is mandatory. Spheros recommends the
usage of a separate bleeding unit (see also Workshop Manual).
Conduct a test run of the heater to check all the water and fuel connec-
tions for leaks and to ensure that they are secure. If the heater suffers a
fault during operation, the fault must be located and remedied.
If the fuel lines should be bled with the heater fuel pump, several start
attempts are required. In this case do not terminate the purge cycle!
