the Coupling Block.
4.
Connect the Polyol hose (blue terminal) to the Polyol input connector (letter R) on the
Coupling Block.
NOTE:
The product hoses
have been distinguished
with red and blue in order
to allow them to be rapidly
identified.
The
red
corresponds
to
the
Isocyanate hose and the
blue corresponds to the
Polyol hose. To avoid
connection
errors,
the
Isocyanate
and
Polyol
hose coupling connectors
are
of
different
sizes,
which makes it impossible

to
be
swapped.
