1 3-way ball valve (BV3)
2 Pump (M6)
3 Sterilisation chamber
4 Cooling coil
5 Canister with water
6 Cooling panel (HE)
7 Manometer (P3)
8 Surge tank (PV3)
9 2-way ball valve (BV2)
• Connect the free connections from the 3-way and 2-way ball valves
(BV3 and BV2) with the canister using the appropriate hoses (i.e.
immerse the loose hose ends in the water).
• Open the 3-way and 2-way ball valves and control the pump in the
Service -> Manual output set -> CircPUMP menu until
the system is filled.
• Stop the pump when gas formation is no longer visible. Close the
valves and disconnect the hoses.
• Connect the 2-way ball valve to the water supply and slowly open the
valve until the required system pressure is reached (approx. 1.5 bar
when cold, see the manometer).
• Close the valve and remove the water hose.
• After some time, observe the manometer reading and check whether
the pressure has fallen (this may indicate a leak).
