Leak detection

The HP POD 20c includes six heat exchanger condensate sensors. Three sensors are located in the drain
pans below each set of heat exchangers, and three sensors are located in the chilled water supply and return
header drain pan tray.
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, which indicates a possible leak.
There should be no water in the chilled water supply and return header drain pan. The drain pan should
always remain dry.

Leak isolation

WARNING:
caution when removing and replacing components that involve water around the electrical
equipment. There is great risk of electrical shock when water is used near electricity.
Task
Inspect, test, and replace as
necessary.
If a leak is detected, see "Leak
detection maintenance
detection" on page 70)."
Inspect and verify that:
•
There is no internal blockage
of the drain line
•
Condensate can freely pass
•
P-traps are intact and not
leaking
•
There is no blockage of the
drain line that is external to the
site drain
Clean and clear debris as
necessary.
Inspect the fan and fan wiring and
verify that:
•
The electrical components are
secure
•
The fan power supplies are
locked into position
Visually check drains for blockage
internal and external to the POD
Conduct an operational check of
the external site drain using
approximately 5 gallons of water
(if permissible or possible)
To reduce the risk of electric shock or damage to the equipment, use extreme
