UNIT STARTING AND OPERATING CONDITIONS
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 ensure 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
9a for operating limits.
