General information!
Dear SPHEROS user,
We assume that the operation and function of your new heater will have been explained
to you properly and to your complete satisfaction by the installing workshop/service
outlet. This owner's handbook is designed to give you a brief summary of how to use the
GBW heaters.
Maintenance and safety instructions
For the heater exists a type approval according to ECE Regulations R122 (Heater) and
R10 (EMC).
The heaters must be installed as described in the attached installation instructions and
must be registered on the vehicle registration document. If applicable, the approval
confirmation or the general operating licence must be carried in the vehicle.
The year in which the heater is used for the first time must be permanently marked on
the heater's model plate by removing the inapplicable year numbers.
Switch off the auxiliary heating system before refuelling.
The heater must not be operated:

nbe operated using the gas type shown on the model plate
(for the NGW 300 with a minimum methane content of 95%)
and the rated voltage shown on the model plate. If the
methane content is lower than this, the heater's gas nozzle is
to be adjusted by SPHEROS trained personnel. The oil content
of the gas must not exceed 70 ppm.
nbe taken out of operation by removing the fuse if smoke
develops, if unusual burning noises are heard or if there is a
smell of fuel. The heater must not be restarted until the unit
has been checked by personnel duly trained by SPHEROS.
nbe run for 10 minutes at least once per months when the
engine is cold and with the blower at its lowest setting. At
the latest at the start of the cold weather the heater must be
inspected by an expert. For this purpose the CO value must
be checked and adjusted. In addition it must be checked
whether disconnecting the control valve results in the
immediately extinguishing of the flame (burning noise). If
not, the controller must be replaced.
nNon-compliance with the installation instructions and the
warnings contained therein will lead to the exclusion of all
liability by SPHEROS. The same also applies if repairs are not
undertaken by professionals or without using genuine spare
parts. This invalidates the type approval for the heater and
its homologation / ECE type permit.
nLiability claims can only be made if the claimant can verify
compliance with all the servicing and safety instructions.
nbe exposed to temperatures of more than 120 °C (storage
temperature), otherwise the electronics may suffer
permanent damage.
nbe operated without at least 20% brandname anti-freeze in
the water of the heating circuit.
nbe replaced after four years for safety reasons
(manufacturer's directive). If you fail to do this it may leak
and gas may escape
nbe drained of oil through the oil drain screw every three
months (by SPHEROS trained personnel).
