HP Performance Optimized Data Center (POD) 20cp manual Humidifier if installed

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 cooling system during the warranty or service contract period shifts all liability to you.

IMPORTANT: Power down the POD after a leak is detected.

Non-isolable leak detection

A non-isolable leak is a leak from the main supply line or the return header.

To repair a non-isolable leak:

1.Power down all IT equipment.

2.Re-direct the leaking water away from the IT equipment.

3.Repair the leak or contact HP if you are still within your service contract.

Isolable leak detection

An isolable leak is any type of leak that does not occur from the main supply line or the return header. To repair an isolable leak:

1.Inspect the zone indicated on the ECS Status Overview screen. You might need to inspect each zone condensate drain pan to determine the exact location of the leak.

2.Power down the IT equipment in the zone where the leak is located.

3.Determine the affected heat exchanger.

4.Close and danger tag the supply and return valves to the affected heat exchanger.

If the heat affected exchanger cannot be identified, close all the heat exchanger supply and return valves in the affected zone and open one supply valve at a time to determine the location of the leak.

5.Repair the leak or contact HP if you are still within your service contract.

Humidifier (if installed)

Component to be inspected	Task	Frequency		Capable Party

Humidifier	• Inspect for water leaks, verify	•	Bi-weekly, if	Qualified personnel
	that no sparks form between	•	staffed
	the electrodes during	•	Quarterly, if
	operation		not staffed
	• Inspect the general operation
	of the cylinder.
Humidifier drains	Verify the following:	Quarterly		Qualified personnel
	• Drains are in working order
	• There is an air gap at the
	funnel/drain entry into the site
	system
	• Drain discharge is not getting
	water on external equipment
	or grounding system
