Periodic maintenance

Perform periodic inspections to ensure that the HP POD 240e NA continues to perform according to design
parameters. During periodic inspections, pay special attention to electrical connections and wiring.
You are responsible for creating and performing detailed preventative maintenance based on HP

recommendations. Data sheets or additional operation and maintenance manuals will be provided for this

task.

CAUTION:

Failure to implement a comprehensive preventative maintenance schedule may result

in reduced efficiency in the HP POD 240e NA, failure of main or subsidiary systems, and loss of

warranty on third party components.

For more specific maintenance information, see the HP Performance Optimized Datacenter 240e NA

Maintenance and Service Guide.

Preparing the Adiabatic units for winter

CAUTION:

Because the Adiabatic units use water, you must take extra precautions during the

winter months to establish safe operating conditions of the HP POD 240e NA.

IMPORTANT:

HP recommends contacting your HP representative prior to winterizing your HP

POD 240e NA for further instructions.

There are three major processes that you must complete to winterize the HP POD 240e NA Adiabatic units.
Complete the following processes in the following order:

Supply header gravity drain (on page

)

Adiabatic unit by unit blowdown (on page

)

Supply header blowdown (on page

)

Your site or POD might have different component locations or a different number of Adiabatic units.
You will need the following items to winterize the Adiabatic units:

•

Air hose adapter—Connects the house air or compressor to the supply header.

•

Adiabatic unit splash deflector—Used inside of each Adiabatic unit to prevent unnecessary splashing.
This splash deflector consists of a hose barb adapter and enough flexible tubing to direct water to the
drain.
