HP Performance Optimized Datacenter 20c User Guide - China

Cooling system 66
The HP POD 20c has one heat exchanger condensate drain.
IMPORTANT: You might need to connect the HP POD 20c drain directly to the local storm or
sanitary drain, depending on the local jurisdiction.
If your HP POD 20c is located indoors, you can connect to an external drain line. If your HP POD 20c is
located outdoors, the water drains out the back of the HP POD 20c.
HP recommends connecting the condensate drain on the HP POD 20c to a facility drain to prevent collection
of water near the HP POD 20c.
Leak detection
The HP POD 20c includes three heat exchanger condensate drains. One drain pan sensor is located in the
drain tray below each heat exchanger on the top of the POD.
There are also three sensors located in the header drain pan, one in each of the three cooling zones.
There should be no water in the header drain pan and the drain pan should always remain dry.
Some amount of condensation water can always be expected in the 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.
