HP Performance Optimized Data Center (POD) 20cp Utilities, Humidifier water supply, Drainage

Utilities

Consider the proximity to required utilities, such as power, water, and network connections. While the required utilities can be brought to nearly any selected site, there is the potential for increased costs and decreased efficiency when the HP POD 20c is located farther from the utility sources.

For utility clearance information, see "Dimensions and clearances (on page 8)."

Humidifier water supply

The HP POD 20c requires supply water for the humidifier. The supply water must meet the following requirements.

Requirement	Specification
Pressure	Between 20 and 110 psi, 0.1 and 0.8 MPa
Temperature	Between 1º and 40°C (33º and 104°F)
Minimum flow rate	1.45 lpm (0.12 gpm)
Connection	1.9 cm (.75 in) G
	Adapter to 1.9 cm (.75 in) FPS
Hardness	No greater than 40°fH (equal to 400 ppm of CaCO3)
Conductivity	100 to 1250 μS/cm
Organic compounds	None
Type of water	Drinking water. Do not use de-mineralized or softened water.
Instant water fill flow	0.6 lpm (0.16 gpm)
rate
Humidifier	For the exact requirements, see the humidifier documentation.

IMPORTANT: If your water is out of range, consult a water quality expert.

In addition to the previous requirements, observe the following requirements and recommendations:

•Do not treat the water with softeners. Softeners can produce foam, which affects the operation of the unit.

•Do not use well water, industrial water, water from cooling circuits, or water contaminated by any chemicals or bacteria.

•Do not add potential irritants to the water, such as disinfectants or anti-corrosive compounds.

•The manufacturer recommends installing an in-line filter for the water supply. It is your responsibility to determine if a filter should be installed, and if so, its location. The filter cannot be installed inside the HP POD 20c and must be compatible with the type of humidifier that is installed.

For more information, see the Operations and Maintenance Manual or the HP Performance Optimized Datacenter 20c Maintenance and Service Guide.
