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 240e NA is located farther from the utility sources.
For utility clearance information, see "Dimensions and required clearances (on page 7)."
System utilities
The site location must accommodate the following utilities:
•Water supply (on page 12)
•Drain locations (on page 13)
•Power (on page 13)
Water supply
An external source of water must be provided for saturating the evaporative media. When the HP POD 240e NA begins operation, the supplied water is used in conjunction with the evaporative media to provide the specified cooling.
The supply water must meet the following requirements.
Requirement | Specification |
|
|
Pressure | |
Temperature | Between 1 °C and 30 °C |
Instant | No lower than the rated flow of the |
| fill solenoid valve (1.5 gpm |
| maximum flow per Adiabatic unit, |
| maximum instantaneous). |
|
|
Connection | ¾” |
Hardness | No greater than 40°fH (equal to |
| 400 ppm of CaCO3) |
Conductivity | 100 to 1250 μS/cm |
Organic compounds | None |
Type of water | Demineralized is preferred. |
| Drinking potable water is |
| acceptable and most likely. |

IMPORTANT: To connect the cooling system, a 0.0127 meter (½ inch) OD copper adapter is needed for water piping.
IMPORTANT: If your water is out of range of these requirements, consult a water quality expert.
In addition to the previous requirements, follow these guidelines:
•Do not treat the water with softeners. Softeners might produce foam, which affects the operation of the unit.
