➀ For conditions other than shown above, please refer to the Modine Breeze AccuSpec program for detailed performance data.
➁ Allowable water temperature range is 100°F to 200°F. Allowable indoor air temperature range is 40°F to 100°F. If temperatures below freezing are expected, provisions
should be made to either drain the unit heater coil or utilize a continually circulating glycol solution.
➂ For conditions other than shown above, please refer to the Modine Breeze AccuSpec program for detailed performance data.
➃ Allowable water temperature range is 100°F to 200°F. Allowable indoor air temperature range is 40°F to 100°F. If temperatures below freezing are expected, provisions
should be made to either drain the unit heater coil or utilize a continually circulating glycol solution.
➄ To use correction factors, start with the 200°F EWT and 60°F EAT data from Table 3.1 and multiply by the factor shown in Table 3.2.
