Course BenefitsThis course is designed to providecoverage of the Trane IntelliPak® Irooftop unit. The course focus is onoperation, start-up, and maintenance of20-130 ton Intellipak I Rooftop units.Proper service techniques will bediscussed to include correct mainte-nance procedures and intervals. Factoryrecommended installation and start upprocedures will also be discussed.Attendees will be able to start-up,operate and program unit controlmicroprocessors. Attendees will alsounderstand control logic and check-outprocedures with unit diagnostics. Uponcourse completion, students will havebeen exposed to the mechanical,electrical and control systems of theseunits and will have become knowledge-able in the start-up, service and main-tenance requirements of these prod-ucts.

Note: Courses may be held in twolocations – at the training center in LaCrosse, WI and at the factory. Thesessions at the factory DO NOT includelive unit hands-on but DO include afactory tour. Refer to the schedule pagefor individual class locations.
