Factory Assisted Start-Up consists of a Desert Aire Service Department Technician to visit the job-site and provide
supervisory experience to installing contractors as they perform the required procedures as outlined in our warranty
activation start-up report. The company technician will also present an educational review of the dehumidifier’s
operating and maintenance requirements. Factory Assisted Start-Up is not an installation bid & therefore the
system must be ready to run before scheduling.
CST Start-Up is performed by a local Certified Service Technician who has been trained by Desert Aire. The CST
performs all duties listed above. In addition they will supply the “items to be supplied for start-up” as listed below.
Please note charges for refrigerant will apply if refrigerant is necessary to complete the start up.
