- a blower assembly disposed under said detachably removable cover section, said blower assembly having
- a housing having an outer wall with a cutaway section defining a blower wheel receiving port;
- a blower wheel disposed in said housing, said blower wheel having a diameter smaller than that of said receiving port;
- an orifice ring having an inner diameter smaller than said blower wheel diameter and being removably attached directly to said housing outer wall so as to retain said blower wheel in said housing but allow removal therefrom by removing said orifice ring from said outer wall and removing said blower wheel from said receiving port; and
- motor means for driving said blower wheel, said motor means being drivingly connected to said blower wheel on its side opposite to that of said orifice ring.
- 2. The climate control unit of claim 1, wherein said attachment means comprises a plurality of vertically oriented bolts driven through said orifice ring and received in said housing top.
- 3. The climate control unit of claim 1, further comprising a motor mount for receiving said motor means, said motor mount including:
- a central hub;
- a plurality of legs disposed on said central hub, each leg terminating in a vertically oriented peg;
- a plurality of peg receiving means attached to an outer housing of said motor means, each peg receiving means receiving one of said pegs.

- 5. A method for disassembling a blower wheel assembly disposed in a packaged climate control unit, said method comprising the steps of:
- providing a detachable cover section for said unit;
- providing a housing having an outer wall with a cutaway section defining a blower wheel receiving port having a diameter larger than the diameter of a blower wheel to be contained within said housing;
- providing an orifice ring removably attached directly to said housing outer wall and having an inner diameter smaller than the outer diameter of said blower wheel;
- removing said cover section;
- disconnecting said orifice ring from said housing outer wall to provide access to said blower wheel; and
- extracting said blower wheel from said blower wheel receiving port of said blower assembly.
- 6. The method of claim 5, wherein said disconnecting step includes the step of unscrewing bolts or screws connecting said orifice ring from said blower assembly.
- 7. The method of claim 5, further comprising the steps of:
- before said removing step, providing a blower motor for driving said blower wheel;
