Installation
DISCALDIRTMAG
®
units may be used in both heating and cooling sys-
tems, 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.
DISCALDIRTMAG
®
air and dirt separators must be installed verti-
cally. In installation conditions where inspection is not possible, it is
recommended that the venting valve cap is replaced by a Calef part
number R59681 hygroscopic safety vent. The standard replacement
cap code number is 59199.
