Table 3.2 Application Envelope for DP400/500
Operating outside this envelope can decrease equipment reliability.
NOTE: When running above 77°F (25°C) supply-air temperature, the superheat readings on the refrigeration circuits
may be higher than 13°F (7.2°C). The EEVs will run out of stroke and limit mass flow, which will result in higher than
normal superheat.
