BLOWER PERFORMANCE
All units employ direct-drive blower motors with
multiple speed taps available. The motors have
been selected to deliver the nominal air volume
against varying external static pressures when
necessary. After installation of the unit, it will be
necessary to check the air volume and change
the motor speed connection accordingly. All
units are factory-wired with the medium speed
winding connected.
A simple method for approximating sufficient air
volume is to measure the difference between the
supply and return air temperatures. In Heating
mode, the air temperature rise should be in the
range of 20ºF to 30ºF. In Cooling mode, the
temperature drop should be between 15ºF to
25ºF. If the values are outside the appropriate
range, increase or reduce the motor speed as
necessary.
