IMPORTANT: The humidifier drain contains concentrated impurities due to the humidification process and is extremely hot. You might need to connect this drain and the supply head drains directly to a local storm or sanitary drain, depending on the local jurisdictional requirements.
Leak detection
The HP POD 20c includes six heat exchanger condensate sensors. Three sensors are located in the drain trays below each set of heat exchangers, and three sensors are located in the header drain pans.
There should be no water in the chilled water supply and return header drain pan, and the drain pan should always remain dry.
Some amount of condensation water can always be expected in the heat exchanger drain pans. If an excessive amount of condensation water accumulates in a drain pan, an alarm is triggered and sent through the HP POD 20c ECS, indicating a possible leak.
For more information on leak detection, see the HP Performance Optimized Datacenter 20c Maintenance and Service Guide.
