F/S C RI (Typ Ista)
1. Check installation for completeness. An
original Ista-EAS must be installed in the
return and a corresponding immersion sleeve
or ball valve in the flow. Caution: In
refrigeration systems, the supply is the colder
pipe and the return is the warmer pipe. The
counter to be installed must then be in the
PolluCom
®
F/S C X RI version with
appropriate adjustment. Please check. In
refrigeration systems, the supply is the colder
pipe and the return is the warmer pipe. It is
simply pulled off upwards and mounted
separately in a suitable place by means of the
supplied wall adapter. (Cable length approx.
30 cm.) Switch off the heating or its circulation
pump.
2. Close the shut-off valves located upstream
and downstream of the single-pipe adapter
(EAS).
3. Check installation point again for correct flow
direction (arrow on the EAS), correct
installation of the EAS if necessary.
4. Unscrew the overflow cap (B) from the single-
pipe connector (A) (SW 22 mm), remove the
seal (C1) from the EAS and clean both sealing
surfaces (A1 and A2) of the EAS.
