Appendix C: CentriVap Specifications
Product Service 1-800-522-7658 47
Environmental Conditions
• Indoor use only.
• Maximum altitude: 6562 feet (2000 meters).
• Ambient temperature range: 41° to 104°F (5° to 40°C).
• Maximum relative humidity: 80% for temperatures up to 88°F (31°C),
decreasing linearly to 50% relative humidity at 104°F (40°C).
• Main supply voltage fluctuations not to exceed ±10% of the nominal
voltage.
• Transient overvoltages according to Installation Categories II
(Overvoltage Categories per IEC 1010). Temporary voltage spikes on the
AC input line that may be as high as 1500V for 115V models and 2500V
for 230V models are allowed.
• Used in an environment of Pollution degrees 2 (i.e., where normally only
non-conductive atmospheres are present). Occasionally, however, a
temporary conductivity caused by condensation must be expected, in
accordance with IEC 664.
