Product Overview
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.
