AdBlue™ and compressed air connections
WARNING
Take care when handling AdBlue™!
Risk of contamination
Avoid contact with skin and eyes.
Wear personal protective equipment
(e.g. protective gloves, safety goggles,
safety shoes).
When handling AdBlue™, observe the safety
regulations applicable to the product. The operator
must procure safety datasheets from the
manufacturer and keep them to hand.
●
Observe space required for additional components
in the installation room (see page 18 Tab. 2)
●
For continuous operation of the Vitobloc 200
EM-530/660 CHP unit (versions SCR and SCR-
ready), an external AdBlue™ supply tank should
be provided.
●
When siting the supply tank, take care to avoid
contact with direc
t sunlight. AdBlue™ freezes at
-11 °C and should not be kept above 25 °C for any
extended period.
●
Both the supply tank and connection hoses must
be installed at a sufficient distance from hot parts
of the CHP unit (e.g. exhaust pipe).
●
The UREA top-up pump (part of SCR system
standard delivery) and the two-way solenoid valve
(anti-siphon valve, not part of standard delivery),
which must be installed directly downstream of the
pump in the direction of flow (according to flow
diagram in technical description for Vitobloc 200
EM-530/660, versions SCR and SCR-ready).
●
The SCR system requires a permanent, external
supply of compressed air. The compressed air can
be provided either through an air compressor or
from a compressed air network (air quality at least
as per ISO 8573-1:2010 [4:-:4]).
●
AdBlue™ and compressed air are connected
during commissioning by trained service
personnel.
