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 8a for operating limits.

Table 8b: Building Commissioning Limits
Commissioning Conditions
Consult Table 8b for the particular model. Starting
conditions vary depending upon model and are based
upon the following notes:
Notes:
1. Conditions in Table 8b 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.
