5. INSTALLATION NOTES Network connection See the technical data table for the specifications 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 figure. CAUTION: the maximum allowed length of an Ethernet connection between two devices is 100 m (for longer distanc- es, use switch P/N KITSE08000). -
Page 17: Distribution System
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. - Page 18 Functional diagrams - room CAUTION: 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.

Page 25: Maintenance
For duct humidification, any biocides used for cleaning can only be added discontinuously. Based on its extensive experience in designing intrinsically-safe high-pressure systems that automatically prevent water stagnation, Carel strongly recommends against using biocides as a cleaning method for the humidifier components in contact with water, unless microbiological con- tamination has been proven. -
