Install Instructions

Installation

DISCAL units may be used in both heating and 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

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 cap.
