Condensation management
CAUTION:
To maintain accurate environmental conditions inside the HP POD 20c, do not leave
the HP POD 20c doors open during operation.
The heat exchanger drip trays collect condensation that forms on the heat exchangers. This collected
condensate drains out of the HP POD 20c through the heat exchanger condensate drain. 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.
The HP POD 20c has one 3.18 cm (1.25 in) condensate drain outlet located at the end of the hot aisle of the
HP POD 20c. The drain outlet is directly connected to the heat exchanger drip trays. The HP POD 20c main
supply and return line is connected to the condensate drain line.
To avoid excessive buildup of condensate and to conserve energy, raise the cooling water temperature to
above the dew point to manage condensation while maintaining the necessary cooling capacity.
Drains
WARNING: Water that drains around the HP POD 20c can cause a potential slip hazard. Use
caution where slip hazards are present.
HP recommends connecting the condensate and humidifier drains from the HP POD 20c to a facility drain to
prevent collection of water near the HP POD 20c. For more information on drain connections, see the HP
Performance Optimized Datacenter 20c Site Preparation and Requirements Guide.
