4. Procedure_________
(Ref. Fig. 601/TASK 36-22-18-991-002, 602/TASK 36-22-18-991-003, 603/TASK 36-22-18-991-004)
Subtask 36-22-18-210-051
A. Inspection of the Overheat Sensing Elements
(1)
Make sure that the clearance between the sensing elements and the duct is approximately 12.7 mm (0.5000 in.) minimum, measured over the full length of the sensing element. (Ref. Fig. 603/TASK 36-22-18-991-004)
(2)
Do an inspection of the elements to make sure that they are installed outside of the insulation.
(3)
Make sure that the clearance between the elements and the duct insulation is the same as at the mounting brackets.
(4)
Make sure that the sensing elements are installed to the permitted tolerance. (Ref. Fig. 602/TASK 36-22-18-991-003)
(5)
Make sure that each clamp has a silicon rubber grommet.
(6)
Make sure that each mounting bracket that is installed directly to the duct has a spacer.
(7)
For the overheat sensing elements 33HF/60HF between the FR39 and FR40:
-Make sure that the material of the spacer is teflon. If it is an aluminum spacer, install a teflon spacer.
(8)
Make sure that the element at FR80 is installed correctly. (Ref. Fig. 603/TASK 36-22-18-991-004)
(9)
Make sure that each mounting and clamp is not damaged and has no corrosion.
(10) Make sure that the bonding straps are correctly installed (Ref. TASK 20-28-00-912-006).
