INSTALLATION	Installation consists of mounting the transmitter and conduit and making
PROCEDURES	electrical connections. Procedures follow for each operation.
Mechanical	Transmitter
	Be careful not to break the neck seal between the sensor module and the
	electronics housing.
	The threaded interface between the sensor module and the electronics
	housing is hermetically sealed before shipment. The integrity of this seal is
	necessary for the safe operation of the transmitter during accident conditions.
	If the seal is broken, reseal it according to “Connecting the Electrical Housing
	to the Sensor Module” on page 5-7.

1.Mount the bracket to a panel or other flat surface as shown in Figure 2-4.Use four 3/8-in. diameter bolts (not supplied with unit). SAE grade 2 bolts were used during qualification testing. Torque each bolt to 19 ft-lb (26 N-m).

2.Attach the transmitter to the mounting bracket, as shown in Figure 2-4.Use four 7/16-20 ￿ 3/4 bolts with washers (supplied with unit). Torque each bolt to 21 ft-lb (29 N-m).
