said first set of power supply conductors routed through said enclosure and said second set of power supply conductors mounted on said chassis and positioned such that advancement of said chassis to said lowered position advances said second set of power supply conductors into electrical connection with said first set of power supply conductors and advancement of said chassis to said raised position electrically disconnects said second set of power supply conductors from said first set of power supply conductors. ### Claim 9 (depends on 5) The equipment enclosure system as in claim 5 further comprising first and second sets of power supply conductors for supplying power from a power source to components of the equipment and first and second mating connectors electrically connecting said first set of power supply conductors to said second set of power supply conductors; said first mating connector mounted on said enclosure and said second mating connector mounted on said chassis such that advancement of said chassis to said lowered position advances said second mating connector into electrical connection with said first mating connector and advancement of said chassis to said raised positions electrically disconnects said second mating connector from said first mating connector. ### Claim 10 An equipment enclosure assembly for mechanical equipment for building systems or processes; said equipment enclosure assembly including: an enclosure with an open top; a chassis for supporting the mechanical equipment, said chassis moveable between a lowered position in which said chassis and said mechanical equipment are retracted within said enclosure and a raised position in which said chassis and said mechanical equipment are raised relative to said enclosure to provide access to said mechanical equipment; and a cover mounted on said chassis over said mechanical equipment and advanceable into and out of covering relationship with said open top of said enclosure. ### Claim 11 (depends on 10) The equipment enclosure assembly as in claim 10 further comprising means for securing said equipment enclosure through a hole in a roof of a structure such that the a portion of said equipment enclosure extends below the roof. ### Claim 12 (depends on 10) The equipment enclosure system as in claim 10 further comprising means for securing said equipment enclosure through a hole in a roof of a structure such that a portion of said equipment enclosure extends into the interstitial space below the roof. ### Claim 13 (depends on 10) The equipment enclosure system as in claim 10 in combination with said mechanical equipment and wherein said equipment comprises heating, cooling or ventilation equipment. ### Claim 14 (depends on 10) The equipment enclosure system as in claim 10 in combination with said mechanical equipment and wherein said mechanical equipment comprises heating or cooling equipment including a blower and a heating or cooling element, said blower pulling air into said enclosure through one or more air inlet openings in said enclosure or said cover, past said heating or cooling element and into a positive pressure plenum formed in said enclosure in part by a bulkhead formed on said chassis around said blower and sealing against an inner surface of said enclosure when said chassis is lowered into said enclosure. ### Claim 15 (depends on 10) The equipment enclosure system as in claim 10 further comprising first and second sets of power supply conductors for supplying power from a power source to components of the mechanical equipment; said first set of power supply conductors routed through said enclosure and said second set of power supply conductors mounted on said chassis and positioned such that advancement of said chassis to said lowered position advances said second set of power supply conductors into electrical connection with said first set of power supply conductors and advancement of said chassis to said raised position electrically disconnects said second set of power supply conductors from said first set of power supply conductors. ### Claim 16 (depends on 10) The equipment enclosure system as in claim 10 further comprising first and second sets of power supply conductors for supplying power from a power source to components of the mechanical equipment and first and second mating connectors electrically connecting said first set of power supply conductors to said second set of power supply conductors; said first mating connector mounted on said enclosure and said second mating connector mounted on said chassis such that advancement of said chassis to said lowered position advances said second mating connector into electrical connection with said first mating connector and advancement of said chassis to said raised positions electrically disconnects said second mating connector from said first mating connector. ### Claim 17 A method of installing mechanical equipment on a roof of a structure, the method comprising: a) providing an enclosure having an open top; b) installing the mechanical equipment in the enclosure; c) mounting a cover relative to the enclosure which selectively covers the open top of the enclosure; d) forming a hole through the roof; and e) securing the enclosure to the structure such that a portion of the enclosure extends through the hole in the roof. ### Claim 18 (depends on 17) The method as in claim 17 wherein the step of securing the enclosure to the structure includes securing the enclosure such that a portion of sidewalls of the enclosure extend above the roof. ### Claim 19 (depends on 17) The method as in claim 17 wherein the step of securing the enclosure to the structure includes securing the enclosure such that a portion of said enclosure extends into an interstitial space below the roof. ### Claim 20 (depends on 17) The method as in claim 17 wherein the step of installing the equipment in the enclosure includes installing the equipment on a chassis that is moveable between a lowered position in which the chassis and the mechanical equipment are retracted within said enclosure and a raised position in which the chassis and the mechanical equipment are raise relative to the enclosure. ### Claim 21 (depends on 20) The method as in claim 20 wherein the step of mounting the cover comprises mounting the cover to the chassis and over the equipment. ### Claim 22 A method of installing mechanical equipment on a roof of a structure in which the roof includes a layer of insulation supported on roof decking, the method comprising: a) providing an enclosure having an open top; b) installing the mechanical equipment in the enclosure; c) mounting a cover relative to the enclosure which selectively covers the open top of the enclosure; d) forming a hole in the roof extending at least down to the roof decking; e) forming a curb around the hole in the roof; and f) positioning the enclosure on the roof such that at least a portion of the enclosure is recessed within the curb and into the hole formed in the roof.
