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
7 for operating limits.

Unit Starting and Operating Conditions
Table 8: Starting Limits
Commissioning Conditions
Consult Table 8 for the particular model. Starting conditions vary depending upon model and are based upon the
following notes:
Notes:
1. Conditions in Table 8 are not normal or continuous operating conditions. Minimum/maximum limits are start-up
conditions to bring the building space up to occupancy temperatures. Units are not designed to operate under
these conditions on a regular basis.
2. Voltage utilization range complies with AHRI Standard 110.
