Installation
DISCAL
™
units may be used in heating or cooling systems to ensure the progressive removal of
air which is continuously formed. The units should preferably be installed after the boiler and on
the pump suction side, as these are the points where the formation of micro-bubbles is greatest.
DISCAL
™
air separators for horizontal pipes must be installed vertically. Flow direction of the
DISCAL
™
air separator is bidirectional: flow in either direction is permitted. In installation conditions
where inspection is not possible, it is recommended that the venting valve cap is replaced by a
Caleffi Code R59681 hygroscopic safety vent. The standard replacement cap code is 59119.
