The safety regulations must be observed during
operation, maintenance and repair of heaters of the
Thermo S series.
For heaters in vehicles, which are not subjected to the
European Directive, inspection and approval by the
respective inspection authority is required, if applicable
regulations are in place.
The year of first start-up must be permanently marked
on the type plate by removal of
not
applicable dates.
The heaters are registered and licensed for the use in
vehicles according to the respective EU Directive 70/156/
ECC (e.g. 2001/56/EC). When using the heater for other
applications not subjected to this EU Directive (e.g. ships),
respective applicable r egulations must be fulfilled.
The heaters are not approved for vehicles subjected to
Directive 94/55/EC (ADR).
The heater may only be installed in the driver's cab or
passenger compartment, if an installation box is used,
which can be tightly sealed vs. the vehicle interior. The
installation box must be sufficiently vented from the
outside.
CAUTION
If the temperature within the installation box exceeds the
permissible ambient temperature of the heater, the
venting opening must be increased after consultation with
Spheros.
Prior to opening the heater it must be disconnected
from the vehicle electrical system.
The heater should always be disconnected from the
vehicle electrical system prior to disconnecting the
temperature sensor plug.
If the order is reversed, t he heater will automatically
be interlocked.
Prior to removing the burner from the heat exchanger,
the temperature sensor plug must be removed.
A temperature of 110°C may not be exceeded in the
heater areas (storage temperature).
Exceeding the temperature may cause heater
malfunctions and permanent damage to the
electronics.
Electrical cables must be routed avoiding isolation
damage (e.g. by pinching, heat development,
bending, fraying, etc.).
CAUTION
NOTE
CAUTION
For risk of poisoning and suffocation the heater may
not be used in closed rooms such as garages or
workshops without exhaust fume extraction. This
also applies when pre-set times/timers are used. This
also applies for burner operation during adjustment
of the CO content in the exhasut dumes.

For explosion risk the heater must be switched off at
gas stations and gas systems.
For explosion risk the heater must be switched off,
when combustible fumes or dust can be generated
(e.g. in the proximity of fuel, coal, wood dust, grain
storage/silos or similar).
The heaters may only be installed in horizontal
position.
WARNING
CAUTION
If operated without coolant (overheating!), the heaters
outer enclosure may reach the ignition temperature of
diesel fuel during operation!
Dripping or evaporating fuel should not accumulate
or ignite on hot parts or electrical equipment.
The heater should be installed as low as possible to
ensure automatic venting of heater and circulating
After coolant replacement sufficient purging of the
cooling system must be ensured. Insufficient venting
heating operation can cause malfunctions due to
overheating.
Proper venting can be recognised by almost noise-free
operation of the circulating pump.
The opening pressure in the vehicle cooling system,
usually indicated on the cooler lid, may not exceed 2.0 bar
working overpressure (also applies to separate heating
circulations).
Hose connections must be secured with hose clamps
against slipping.
The tightening torques of the used hose clamps must
be observed.
WARNING
pump. This in particular applies for the circulating
pump, which does not automatically draw.
