12. Glue an H system (pipework) to the outside air outlet to pre‐
vent dirt or rain water from penetrating inside (e.g. may be
assembled using 3 T-pieces).
CAUTION!
– Do not position the air outlet in the
vicinity of:
– Suction openings
– Windows
– Chimney openings
– Take into account the wind dynamic
pressure, e.g. at the side of a building
– Use a Ø160 mm pipe if lines are too long
or there are more than 3 bends

14. For the “external product storage tank”: Connect the PVCU
connector Ø 32 (C) "Product outlet” and the connector on the
external product storage tank (J).
15. Connect a reinforced PVC hose Ø 6x12 mm between the "Fill
brine storage tank” connector (B) and the connector Ø 6x12
mm on the brine storage tank (K).
16. Connect a reinforced 9x12 mm PE hose between the brine
storage tank (K) and the “Brine inlet” connector (D).
19. Electrical connectors - as per the electrical circuit diagram:
Connect the external alarm contact to the control cabinet -
