Materials are classified to Huawei-provided, self-purchased, and onsite prepared
materials, which are marked as mandatory, optional, and engineering purchasing
in this document.

Issue 06 (2020-08-19)
NO TE
● When the device is under negative pressure: H1 = H2 ≥ P/10 + 20 mm.
● P: absolute static pressure at the water pan drain port, measured in Pa.
NO TICE
Air channel installation: Install a flexible pipe between the NetCol8000 and
the air channel connector. The weight of the NetCol8000 is not borne by the
air channel. Engineering air channels need to be supported to ensure that the
air channels and NetCol8000 connections are not forced.
Pipe thermal insulation: Take thermal insulation measures for all inlet and
outlet pipes of the NetCol8000. Leave space for operating and maintaining
thermal insulation for valves and joints. Take insulation measures at low
temperatures to prevent freezing in the water pipe.
Mandatory: mandatory configuration. This material is provided by Huawei
and can be found in delivered fittings.
