(620.60 deg.F) the sleeves will become transparent.
B. Procedure
____NOTE : The hot-air tool must have a pre-heating time to be at the set
R heating temperature. Approximately 1 minute is necessary for this
R procedure.
R Do not start the shrinking process before then.
R
-Use the correct dimensions of refLector to agree with the dimensions of the sleeve.
20-25-31 Page 820-25-31 Page 9
- Put reflector in generator.
- Set generator to "ON".
- The thermoplastic rings melt and the outer sleeve shrinks after a few
seconds.
- If there is a solder sleeve, continue heating until the solder preform
melts (The solder ring can collapse immediately before the flow of
solder, but this does not show that the joint is completed).
- At this step, remove the sleeve assembly from the heat stream.
Shrinking is completed as the sleeve becomes cool and goes back to its
initial color.
R ____NOTE : To extend the service life of the heating elements, it is
R recommended to operate the hot-air equipment with cold air for
R approx. 1/2 to 3 minutes (refer to the type of equipment) before
R you set them to off.

NOTE : The tool must obey the related operating and safety instructions and be applicable for its related use.
__________________________________2. Infrared Generator Characteristics
A. Type ED-7-001 (Ref. Fig. 001) The mobile generator ED-7-001 is used with a gun IR1759 (STANDARD
R OPENING) or IR 3104 (LARGE OPENING) and an external reflector. An extension flex AT-7-101 is supplied to use guns with 24V in aircraft. Generators supplied with an extension flex are adjusted and cannot be used without an extension flex unless they are re-adjusted.

------------------------------------------------------------------------
This generator can be used in manual or automatic mode.
In manual mode, the generator operates as a simple switched supply for
the gun and is turned on and off by trigger on the gun. In this mode the
generator always supplies full power to the gun while the trigger is
depressed.
Timer operating principle :
Use "CHAUFFE" (Heat) coded wheels to show heating time in seconds,

Example : For a 24 second heating time, show 2 and 4. In automatic mode, you can set the generator to control the gun with one of twenty stored program sequences. Each sequence controls the time and level of the supply voltage to the gun. The sequence is start by pressing and releasing the trigger on the gun and continues until automatic completion or until the trigger is pressed again. To start the sequence, push and release the trigger on the gun. The sequence continues until it is automatically completed or until you push the trigger again.
B. Type ED-7-004 (Ref. Fig. 002) Mobile generator ED-7-004 is used with a gun IR1759 (STANDARD OPENING) or IR 3104 (LARGE OPENING) and an external reflector. An extension flex AT-7-101 is supplied to use guns with 24V in the aircraft. Generators supplied with an extension flex are adjusted and cannot be used without an extension flex unless they are re-adjusted.
