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.
Starting Conditions
Consult Table 9 for the particular model number.
Starting conditions vary depending upon model number
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 ARI
Standard 110.
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.
