INSTALLATION
Mounting Adapters
The TAC2000/TAC3000 fan is supplied with either a
pre-machined mounting adapter or a generic
mounting adapter. Pre-machined mounting
adapters are machined for your pilot and bolt circle.
Generic mounting adapters require a pilot and bolt
circle machined into them to match the pilot and
bolt circle of your fan drive. Contact Flexxaire for
machining instructions if you are using a generic
mounting adapter. For some applications, a wider 2-
piece adapter may be used, and the necessary
hardware for assembling the 2 parts together will be
included. This 2-piece adapter may be pre-
assembled.
