SPECIFICATION SUMMARIES
Installation
DISCALDIRT
®
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.
DISCALDIRT
®
air and dirt separators must be installed vertically. In
installation conditions where inspection is not possible, it is recom-
mended that the venting valve cap is replaced by a Calef part num-
ber R59681 hygroscopic safety vent. The standard replacement cap
code number is 59199.
