Is there a nec code reference that says i can or cannot use a pull out disconnect (normally used in hvac service) as a disconnecting means for a motor.

My application: 110v 3/4 hp blower exhaust motor - outside - using 60a rated nema4x enclosure - lock can be placed on enclosure

i have spoken with manufacturer and they say it is ok but i would like to have a nec reference
 
You won't have a specific Code reference to that disconnecting means.
The requirement s for motor disconnects are covered by Part IX of Art. 430 starting at 430.101.
As long as any device meets the requirements of that section it should be acceptable.
I know of no problem with what you describe ( as long as the environment is suitable)

Good point. But why aren't pullouts mentioned in 430.109? I'm assuming pullouts must be UL listed as one of the items in 430.109. Maybe they are UL listed as a motor-circuit switch, or maybe a manual motor contoller?
