Instructions

Installation
DISCALDIRT units may be
used in both heating and
cooling systems, to ensure
continuous air and dirt
elimination. The units should
be installed after the boiler
and on the pump suction
side, as these are the points
where the formation of
micro-bubbles is greatest.
DISCALDIRT air and dirt
separators must be installed
vertically. In installation
conditions where inspection
is not possible, it is
recommended that the
venting valve cap is
replaced by a Caleffi part
number R59681
hygroscopic safety vent.
The standard replacement
cap code number is 59199.
