Small flange connections

70 / 107
The vacuum checks must be carried out when the ice condenser is
frozen.
Leakages are often due to improper small flange connections between the
various components and hose connections or to leakages in the valves.
•
Loosen the connection and place the centring ring (with sealing ring
inside) in a centred manner between the flange connections.
•
Seal the connection with the clamping ring by tightening the wing nut.
•
Ensure that the centring ring neither slips out of place nor gets jammed.
