Mechanical Attachment Installation
Step 2: Install the Mechanical Attachment
1.
Install the Mechanical Attachment once it has been placed appropriately. Consult the
manufacturer’s installation instructions and specifications regarding the proper installation and
flashing of the Mechanical Attachment.
Step 3: Connect the Mechanical Attachment to the Ballast Tray
1.
Once the Mechanical Attachment is installed you can connect the Mechanical Attachment to the
Ballast Tray.
2.
Place the Ballast Tray on the South Supports. Match the Ballast Tray hole to the Mechanical
Attachment stud. Connect the Ballast Tray to the South Supports with 4 bolts. (In some
instances the Ballast Tray must be forced down to be able to install the washer and nut)
NOTE: Extra washers are supplied with the Attachment Hardware Kit to act as a compression
stop below the tray. Washers or other suitable compression stop must be used to ensure that a
maximum distance of 1” below the bottom of tray and compression stop is achieved.
In some
cases a coupling nut may be required in the event that the stud of the attachment is not of
sufficient length. This will prevent excessive Ballast Tray deformation and allow appropriate
application of torque.
