Page 8: Section 2 Installation Considerations
The SAE5-35 does not require warm up unless the outside temperature is below 20 degrees C. When warm up time is required, the internal heater is capable of warming the SAE5-35 from -20 degrees C to operating temperature in less than two minutes. -
Page 9: Section 3 Installation Procedures
The SAE5-35 is supplied with a mounting tray and solder type mating connectors. It is important that proper solder techniques be observed in attaching wires to the mating connectors. Failure to do so could result in a failure in the connection and cause intermittent or non operation of the SAE5-35. EQUIPMENT REQUIRED 3.2.1... -

“D” shaped hole is used to mount the brass fitting into the front panel. Upon completion of installation of the SAE5-35, a Case Leak test is to be performed per FAR Part 43 Appendix E... - Page 11 SAE5-35 power input to the transponder circuit breaker. Alter- natively, the two power pins, 8 and 14, are internally connected in the SAE5-35. Only one of these connections is necessary to supply power to the unit. The unused connection can be used to drive a panel-mounted indicator if desired.

Page 12: Figure 3-2 J4/J5 Connector Wiring
The SAE5-35 uses Sub-D solder cup connectors with screw lock assemblies. Proper wire attachment and assembly of the screw locks and connector hood are shown in Figure 3-2 and 3-3. It is recom- mended that each wire and solder cup be covered with a piece of shrink tubing or other insulator. -

6. If the AIM function uses annunciator 4. Pin 8 and 14 are internally connected in the lamps provided by the installer, they SAE5-35. Only one line is necessary to supply should be appropriately labeled. The power to the unit. The unused power pin may lamp connected to pin 9 should be be used as a power loss indicator if desired. -
Page 15: Calibration
4. See Figure 3-5 for AIM function interconnect wiring. 3.6 CALIBRATION The SAE5-35 is calibrated at the factory to a pressure datum traceable to the National Bureau of Standards. However, when the encoder is installed in the aircraft it must be recalibrated to corre- spondence to the primary flight altimeter, refer to FAR 91.217 and FAR 91.413 for details. -
Page 16: Calibration Procedures
43 section E. Verify compliance with AC-43.13 as appli- cable. 1. Connect the pitot-static test set to the aircraft static system. The SAE5-35 must be connected to the aircraft static line near the flight altimeter and the two altitude adjust- ments buttons must be accessible. -
Page 17: Placarding
Figure 3-8 SAE5-35 Adjustment 3.6.3 Placarding We recommend that the altimeter used for flight reference and the SAE5-35 be placarded with the following information: Replacement or re-calibration of the altimeter used for flight reference requires re-calibration of SAE5-35 Altitude Encoder. -
