sink. It is important to follow the proper tightening sequence to avoid warping the heat sink, which can reduce thermal contact
between the POWERTAP and heat sink.
STEP 1:
Locate the POWERTAP on the heat sink and
start mounting bolts into the threads by hand
(2 or 3 turns).
STEP 2:
Finger tighten the center bolt. The bolt may
catch on the threads of the heat sink so it is im-
portant to make sure the face of the bolt or
washer is in contact with the surface of the
POWERTAP.
STEP 3:
Tighten each of the end bolts between 5 to 10
in-lb.
STEP 4:
Tighten the center bolt between 8 to 10 in-lb.
STEP 5:
Finally, tighten the end bolts between 30 to 40
in-lb.

flexible leads is recommended for the anode connections. Use of thermal grease is highly recommended.
