GENERAL PERFORMANCE AND ELECTRICAL DATA - MODEL PTC
Table 5.1 - Propeller Unit Heater Model PTC General Performance Data
Table 5.2 - Model PTC Operating Electrical Data ➄
➀ Ratings shown are for elevations up to 2,000 ft. For elevations above 2,000 feet, ratings should be reduced at the rate of 4% for each 1,000 feet above
sea level (in Canada see rating plate). Reduction of ratings requires use of a high altitude kit.
➁ Data taken at 65°F ambient and unit fired at full-rated input. Mounting height as measured from bottom of unit, and without deflector hoods.
➂ All motors used are produced, rated and tested by reputable manufacturers in accordance with NEMA standards and carry the standard warranty of both
the motor manufacturer and Modine. All motors are totally enclosed and all single phase motors have built-in thermal overload protection.
➄ Amp draw data shown is operating amp draw at incoming power. For units that use a field installed accessory step-down transformer as noted, the amp draw shown is
the primary side operating amp draw. For sizing of circuit protection for equipment with transformers, please refer to the National Electric Code.
