2 Safety notes

2.1 Correct use
Safety in operation is only guaranteed if the stainless
steel distributor/collector "Multidis SFQ" is used
correctly.
The stainless steel distributor/collector "Multidis SFQ"
is used in hot water central heating and/or cooling
systems for individual room temperature control in
surface heating and cooling systems.
The integrated valve insert "QM" serves the automatic
flow control (hydronic balancing) in the surface heating
and cooling systems.
They are only suitable for operation with unpolluted,
non-aggressive fluids (e.g. water or suitable water and
glycol mixtures according to VDI 2035).
Any use of the stainless steel distributor/collector
"Multidis SFQ" outside the above applications will be
considered as non-compliant and misuse. Claims of
any kind against the manufacturer and/or his authorised
representative due to damages caused by incorrect
use cannot be accepted.
The observance of the installation and operating
instructions is part of the compliance terms.
2.2 P ossible dangers at the installation location
and during transport
The case of an external fire has not been taken into
consideration when constructing the stainless steel
distributor/collector "Multidis SFQ".
!
WARNING
Hot or cold surfaces!
Risk of injury! Do not touch without safety
gloves. The stainless steel distributor/collector
"Multidis SFQ" may get very hot or cold during
operation.
Sharp edges!
Risk of injury! Only touch with safety gloves.
Threads, bore holes and edges are sharp.
Small components!
Risk of ingestion! Store and install the stainless
steel distributor/collector "Multidis SFQ" out
of reach of children.
Allergies!
Health hazard! Do not touch the stainless
steel distributor/collector "Multidis SFQ" and
avoid any contact if allergies against the used
materials are known.
