Water from natural condensation might form. Condensation from the heat exchangers flow to the three
condensate drains across the rear of the HP POD (1). The water main drain catches any water from a
water main leak (2). The humidifier drain removes excess water from the humidifier (3).
Item Component
1 Heat exchanger condensate drains
2 Water main supply/return drain
3 Humidifier drain
IMPORTANT: You might have to pipe directly to your local storm or sanitary drain,
depending on local jurisdiction.
If your HP POD is located indoors, you can connect to an external drain line. If your HP POD is located
outdoors, the drained water will simply drip from the HP POD drains out the back of the HP POD.
HP recommends connecting the condensate drains on the HP POD to a facility drain to prevent collection
of water near the HP POD.
Leak detection
If too much water accumulates in a drain tray, then an alarm is triggered and sent through the HP POD
ECS, indicating a possible leak. For more information, see HP POD ECS alarms ("ECS alarms" on page
37).
