IOM Instructions

Operating Limits

Environment – Units are designed for indoor installation only. Never install units in areas subject to freezing or where
humidity levels could cause cabinet condensation (such as unconditioned spaces subject to 100% outside air).
Power Supply – A voltage variation of +/– 10% of nameplate utilization voltage is acceptable.
Determination of operating limits is dependent primarily upon three factors: 1) return air temperature. 2) water
temperature, and 3) ambient temperature. When any one of these factors is at minimum or maximum levels, the other
two factors should be at normal levels to insure proper unit operation. Extreme variations in temperature and humidity
and/or corrosive water or air will adversely affect unit performance, reliability, and service life. Consult Table 6a for
operating limits.
