5.2 Distribution system
5.2.1 Drain valve management (NOL)
The pumping station manages and controls the line drain valve (NOL, normally open). The zone panel can also manage a con-
nected line drain valve.
Notice: the line drain valve must be fitted at the lowest point in the water circuit and wired to the nearest electrical pan-
el (pumping station or zone panel), so that when opened, the entire system is emptied.
Case 1: Pumping station located below the distribution manifolds
Connect the drain valve near to pumping station that will control its opening.
Case 2: Pumping station located above the distribution manifolds, placed at different heights.
The drain valve must be connected near to the lowest distribution manifold.
Notice: the control signal for the zone 12 drain valve is output J12 NO3 on the zone electrical panel controller. See the
corresponding manual.
Case 3: Distribution manifolds located both above and below the pumping station
Connect multiple drain valves at the lowest points in the water circuit.

IMPORTANT: the blower fill and drain valves are contained in the directbox hydraulic panel. The maximum allowable
length for the water line leaving and re-entering the directbox or that, if no directbox is installed, connects the fill valve to the
drain valve, is 1181 inches.
Notice: when making the water connections, always observe the following warnings:
• limit as much as possible the length of the fill/drain line on each distribution circuit;
• ensure a minimum slope of the piping to assist emptying during the drain cycle.
