Quietflex wrapper insulation.
ASPT[33,39,47]BA
Revision change on ASPT33C14/39C14/47C14 air handlers to change the amps in electrical
data which ends reducing the MOP size from 35 to 30 and thus increasing wire gauge size in
the field for the 5kW heater kit
ASPT35B14AB
The SR plate format is changing from SR075 to SR099 and in order to track this change a
