5. INSTALLATION NOTES
5.1 Network connection
See the technical data table for the specications of the connection cables.
5.1.1 Zone panel connection
The connection is made using an Ethernet cable from the pumping station to the zone panels, as shown in the gure.
IMPORTANT: the maximum allowed length of an Ethernet connection between two devices is 100 m (for longer dis-
tances, use switch P/N KITSE08000).

5.1.2 Supervisor connection
The connection to the supervisor network can be made in two ways:
• between the Ethernet port on the pumping station and the supervisor network
• via RS485 serial link between the BMS2 port on the pumping station controller and the supervisor network. In the latter case,
the communication settings need to be changed when commissioning the system.

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 tted 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 dierent 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 ll 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 ll 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 ll/drain line on each distribution circuit;
• ensure a minimum slope of the piping to assist emptying during the drain cycle.
