Unit Commissioning and Operating Conditions

Operating Limits
Environment – Units are designed for indoor installation only. Never install 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 aff ect unit performance, reliability, and service life. Consult 10a for operating limits.

Commissioning Limits
Consult Table 10b for the particular model. Starting conditions vary depending upon model and are based upon the following
notes:
Notes:
1. Commissioning limits in Table 10b 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 ARI Standard 110.
