Some of the info we offer in our downloads can be quite old. It’s rare that prices
for parts are listed in manuals, but if you see any please ignore them as the
prices are probably obsolete.
Most manuals contain parts lists and diagrams. The older the unit, the more
you’ll find obsolete parts. In same cases the parts may still be available, but
under a new part number. In other cases a generic part may be suitable for use.
For help in finding parts, please visit our parts store at
www.HVACpartstore.com.
Please note that specifications and illustrations are subject to change without notice and without
incurring obligations.
The information contained in this download is for the use of qualified individuals who have been
trained to interpret this data. All repairs on HVAC equipment should be performed by a qualified
technician. In some states, counties or cities, the law states that repairs must only be done by
licensed individuals. Persons not legally or technically qualified should not attempt to interpret
this information or perform any repairs
