Table 7.2 - Blower Unit Model HDC and BTS Operating Electrical Data
M 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.
N Data taken at 55°F air temperature rise. At 65°F ambient and unit
fired at full-rated input. Mounting height as measured from bottom
of unit, and without deflector hoods.
O 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.
Model HDC motors are open drip proof, while model BTS motors
are totally enclosed and all single phase motors have built-in
thermal overload protection.
P 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.
Q For BTS models, add the Motor Amp Draw and Control Circuit
Amp Draw to get the Total Unit Amp Draw.
R Transformers for blower models are typically smaller than those
used for propeller models, as the transformer is not needed for
the blower motor. Size 300-400 use a PSC power exhauster motor,
further reducing the required transformer size.
