Leak detection maintenance
WARNING:
To reduce the risk of electric shock or damage to the equipment, use extreme
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.
CAUTION:
If a serious leak develops, shut down the POD immediately and isolate the chilled
water cooling system from the site. Contact HP immediately to initiate a field service call. Do not
attempt to repair the chilled water cooling system. Attempting to self-repair the chilled water
attempt to repair the chilled water cooling system. Attempting to self-repair the chilled water
cooling system during the warranty or service contract period shifts all liability to you.
IMPORTANT:
HP recommends shutting down the POD after a leak is detected. For more
information, see "Power down procedure" in the user guide.
