Environmental considerations

Environmental risks

• Avoid placing the HP POD 20c directly along a drainage path or in an area prone to flooding.

• Verify that the HP POD 20c is properly grounded in accordance with national, regional, and local

regulations, ordinances, codes, and the product specifications.

Cold weather

The HP POD 20c requires a site chilled water supply and return, humidifier supply and drain, and

condensate drains. Extreme cold weather can cause damage to the supply and drain lines. Evaluate the

following for additional cold weather protection:

• Regional location of the HP POD 20c

• Exposure of the supply and drain lines to extreme cold temperatures

Extreme cold weather can affect crane and lifting operations. When temperatures drop below -12.2°C

(10°F), appropriate consideration must be made with respect to shock loading, crane hydraulics, and

possible de-rating of the crane.

Areas prone to lightning or power surges

The HP POD 20c structure and internal components are all bonded together. A common grounding electrode

conductor connection point is provided. Properly bonding and grounding of the HP POD 20c minimizes the

effects of a lightning strike. A surge protection device is provided on the HP POD 20c input connection to

protect the HP POD 20c electrical system from voltage transients. If your site is in an area that is subject to

frequent lightning strikes, the HP POD 20c must be protected per all national, regional, and local regulations,

ordinances, codes, and the product specifications. HP recommends that you contact a certified lightning

protection consultant.

Seismic activity

If your site is in an area that has frequent seismic activity, HP recommends that you contact a seismic activity

consultant. If your site is in an area that has high vibration level, HP recommends that you contact a vibration

isolation consultant. You must specify the method of anchoring the HP POD 20c, if necessary.
