Prerequisites:
1/ 2, 7/ 16, and 11/ 16 sockets
5/ 8 wrench
Philips screw driver
Power tools (optional)
Note: Use care when handling the RU, as it is heavy. Fujitsu recommends installing the RU on a two-person
team to avoid damage to the unit or injury to the user. If the RU is to be installed at a high location, Fujitsu
recommends using lifting equipment to hoist the RU by a pair of eye bolts mounted on the RU.
Step 1
Remove the eight M 8 screws on each side of the RU.
Step 2
Using the RU L-Bracket Kit (PCD4B780-0007-C001), install the L-brackets to each side of the RU and secure them
using the M8 screws, flat and split washers.
Note: Ensure proper L-bracket positioning on the RU. Refer to
Figure 17 for an example.
Step 3
Torque each M 8 bolt to 9.28 Nm to secure the L-brackets to the RU.
Step 4
Screw in two M 8 eye bolts (PCD4B780-0008-C001) with flat and split washers in the two holes on top of the RU
and torque them to 13.4 Nm.
Note: The RU is heavy and these eye bolts are used to hoist it to the top of the tower for installation.
