OPERATING PROCEDURES

SECTION I. UNIT OPERATION
4-1. GENERAL
Correct operation of the TI2000GPU-24 (Turbo Start 2000) includes
both pre-use and operational checks of the unit. Knowledge of the
operating limits, restrictions, performance, unit capabilities and
functions is fundamental to correct and safe operation. The operator
shall ensure compliance with the instructions in this manual that
affect operational safety and the warranty of the unit.
4-2. OPERATING LIMITS AND RESTRICTIONS
The minimum, maximum and normal operating ranges result from careful
engineering and evaluation of test data. These limitations must be
adhered to during all phases of operation. Refer to Chapter 3, Sec-
tion II, OPERATING LIMITS AND RESTRICTIONS, for detailed information.
4-3. PERFORMANCE
Refer to Chapter 5, PERFORMANCE DATA to determine the capability of
the Turbo Start. Consideration must be given to changes in perfor-
mance resulting from variations in ambient temperature, mode of op-
eration, state of charge (with or without 120 or 240 VAC power), and
aircraft DC bus system inefficiency (voltage drops).
