tubes and liquid detection cable are placed towards the rear of the chassis. Using a Torx #T20 screwdriver, tighten the
captive screws in the order that is mentioned below:
NOTE:
The captive screw numbers are marked on the heat sink and are tightened to a torque value of 12.0 ± 1.2 lbf-in.
a. Partially tighten the captive screws 1 and 2 (approximately 3 turns).
b. Partially tighten the captive screws 3 and 4 (approximately 3 turns).
c. Tighten the captive screws 1 and 2 completely.
