Periodic maintenance 63

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.
