Unit Start Up
98 RT-SVX36K-EN
Notes:
1. Compressors for the 20 thru 30 Ton units can operate individually or together and in any order while in the SERVICE TEST mode.
2. Compressors 1A &1B and compressors 2A & 2B operate simultaneously within their respective circuits on the 40 thru 75 Ton units. There is no 1B compressor for variable speed.
3. Condenser fan outputs can operate individually or together and in any order while in the SERVICE TEST mode.
4. Once the unit has started, refer to the Status Menu in the Human Interface for the OA CFM.
5. RTM OCC/UNOCC output in the Service Test Mode must be in the unoccupied mode to open the system VAV boxes or to drive the VFD to 100%.
IMPORTANT: Do not operate the compressors without the supply and condenser fans; low suction or high head pressure will develop and compressor
damage may occur.
