SERVICE BULLETIN 010
LC / LV FACTORY START-UP SUPERVISION
A Factory Start-Up
requires a Desert Aire Service Department Technician to visit the jobsite 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.
A CST Start-Up
is performed by a local Certified Service Technician who has been trained by Desert Aire. The CST performs all
duties of commissioning and also trains responsible parties on the proper maintenance and operation of the unit.
“Factory Start-Up is not an installation bid & therefore the system must be ready to run before scheduling.”
The Desert Aire Service Dept. will advise contractors of their responsibilities and coordinate all site visits. This start-up procedure
may be performed by Desert Aire OR an authorized Certified Service Technician. This document requires a signature and must be
returned to Desert Aire before the Factory- or CST-supervised start-up can be scheduled. Desert Aire will confirm the start-up dates
upon receipt of the pre-start-up checklist.
If a return trip must be scheduled due to insufficient jobsite preparation, a second
P.O. # must be issued to Desert Aire for re-scheduling.
The following list of items will apply to all start-ups and is the responsibility of the installing contractor. If you are unable
to supply any of the following equipment, you must contact Desert Aire before signing this document. You can reach
Desert Aire at (262) 946-7400.
