BEFORE POWERING UNIT, check the following:
Operating Limits
Environment
– This unit is designed for indoor
installation ONLY.
Power Supply
– A voltage variation of +/– 10% of
nameplate utilization voltage is acceptable.
Starting Conditions
GT-X Units
– Units start and operate in an ambient of
45°F with entering air at 45°F, entering water at 32°F
and both air and water at the stated flow rates of ISO/
ASHRAE/ARI 13256-1 for initial winter start-up.
Notes:
1. These are not normal or continuous operating
conditions. It is assumed that winter start-up
is to bring the building space up to occupancy
temperatures.
2. Voltage utilization range complies with ARI
Standard 110.

Table 11: Operating Limit
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 corrosive water or air will adversely affect unit
performance, reliability and service life.
