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.
