DISASSEMBLY/ ASSEMBLY PROCEDURES
1. Mounting Hardware Removal
NOTES: Refer to Figure 4 for Procedures 1 and 2
unless otherwise specified.
Older versions of the unit contain different
mounting hardware than newer versions of the
unit.
If you have an older version of the unit,the
mounting hardware will consist of 2 threaded tie
rods (not shown) and 4 acorn nuts with washers
(not shown). Refer to step A. for disassembly
instructions.
If you have a newer version of the unit,the
mounting hardware will consist of 2 long screws
(3) which thread into 2 pem nuts (part of the
mounting straps (5). These screws have a hex
head with a built-in washer. Some newer units also
have 1 additional washer located on the end of
each screw. Refer to step B. for disassembly
instructions.
A. For older units: Remove 1 7/16" acorn nut
(with washer) from each threaded tie rod. Another
tool may be needed to hold the acorn nut on the
other end of each rod to prevent the rod from
turning.
Slide each tie rod through the holes located in the
mounting straps. (The rod covers (4) will also slide
off). Remove the mounting straps by pulling them
carefully away from the unit.
B. For newer units: Unscrew the 2 long screws
from the 2 pem nuts (part of the mounting
straps). Pull the screws through the holes
located in the mounting straps. (The rod covers
will also slide off). On newer units there may also
be 1 washer located on the end of each screw. It
is not necessary to remove either washer.
Remove the straps by pulling them carefully
away from the unit.
NOTE: Figure numbers of exploded views will
be referred to throughout these procedures.
Certain parts will be referenced. The item
number in each figure which corresponds to the
part will be enclosed in parentheses-i.e.-rod
cover (4).
2. Mounting Hardware Replacement
A. For older units: Position the 2 mounting straps
(5) so that their screw holes line up with the 2
wide "channels" (between the fins) on each edge
of the heatsink (Figure 6,Item 1). See Figure 4
for proper strap orientation. Slide the 2 threaded
tie rods through the holes located in the mounting
straps. Make sure that the rod covers (4) are in
place before securing the rods to the straps.
NOTE: 2 of the acorn nuts (not shown) should
already be secured on the end of each tie rod.
B. Replace 2 of the 7/16" acorn nuts (with
washers). Another tool may be required to hold
the other acorn nut on each rod.
C. For newer units: Position the 2 mounting
straps so that their screw holes line up with the 2
wide "channels" (between the fins) on the edges
of the heatsink. See Figure 4 for proper strap
orientation. Some newer units have washers that
are located on each screw. Make sure that the
washers are in place before sliding the rod covers
on. Make sure that the rod covers are in place
before securing the screws to the straps. Thread
the 2 long screws (3) into each pem nut (part of
the mounting straps). Make sure that both long
screws are securely fastened.
3. Junction Box Cover Removal
NOTE: Refer to Figure 4 for Procedures 3 and 4
unless otherwise specified.
A. Loosen the 4 screws (9) which secure the
junction box cover (8). Slide the cover so that the
screws are released from the smaller section of
the screw hole. Lift the cover away from the
junction box (7).
