Leaflet 'gerchamp-cdu3680-l2l-680kw-leaflet-a0.pdf', Version A0 2026/04/15, two pages; specification table on p.2 headed '680 kW / 48U / L2L CDU'. THE MODEL NUMBER 'CDU3680' IS NOT PRINTED ANYWHERE ON THE LEAFLET: p.1 headline is '680kW/48U L2L In-Row CDU'. The model number comes from the product web page (H1 'CDU3680 L2L 680kW'), which links this exact PDF and reproduces the leaflet figures. 'Bluearth' as the line name is from the web page. Form factor is the manufacturer's own ('In-Row CDU'); the '48U' in the headline is the cabinet height, not a rack-mount size, and rack_units_u is forbidden for in_row. Pump redundancy is NOT written: p.1 says 'N+1 pump configuration' while the p.2 table says 'Single pump (N) / dual pump (N+N) / dual pump switchover' (see conflicts). The leaflet labels both pump-mode flows 'Maximum flow rate'; per the brief, single-pump is recorded as the nominal flow at 1 pump and dual-pump as the maximum. REVIEW 2026-09-22: every value re-read on the rendered page by the reviewer; leaflet https://www.gerchamp.com/media/d/gerchamp-cdu3680-l2l-680kw-leaflet-a0.pdf (Version A0 2026/04/15) is the figure source, the product page is cited because it prints the model number. QUARANTINED, not stored: depth (table 1050 mm vs p.1 footprint 1200 x 600 mm), pump redundancy (p.1 'N+1' vs p.2 'N / N+N / switchover'). noise_dba 54 is the printed BOUND. tcs_supply_temp_min/max_c carry the printed secondary coolant window 10-55C. 550 kg printed without a dry/wet qualifier, not stored.
