Utilities
Proximity to utilities and drains
Consider proximity to required utilities, such as power, water, and network connections. While required
utilities can be brought to nearly any selected site, there is a potential for increased costs and decreased
efficiency when the HP POD 240a is located further from the utility source.
For utility clearance information, see HP POD 240a dimensions and required clearances (on page 8).
System utilities
The site location must accommodate the following utilities:
 Water supply (on page 15)
 Drainage (on page 16)
 Power (on page 17)
Water supply
The HP POD 240a requires supply water for the humidifier. The supply water must meet the following
requirements:
Requirement Specification
Pressure
between 0.1 and 0.8 MPa (1 and
8 bars)
Temperature
between 1 and 40 °C
Instant flow-rate
no lower than the rated flow of the
fill solenoid valve
Connection
G3/4M
Hardness
no greater than 40°fH (equal to
400 ppm of CaCO3)
Conductivity
125 to 1250 μS/cm
Organic compounds
None
 Do not treat the water with softeners, because softeners might 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 disinfectants or anti-corrosive compounds to the water, which are potential irritants.
For additional dimensions, see the HP Site Preparation Drawing Package (on page 6).
