Preparing for Installation

About the Sun Rack Cabinet Extension

Ensure that you plan the installation process ahead of time. You may need to power-off systems and disconnect cables to install the cabinet extension.

You can install the Sun Rack cabinet extension on the front or the back of the Sun Rack 900-38, 1000-38, and 1000-42. The rear door hinges of all Sun Racks are identical (FIGURE 1-1).

To install the cabinet extension on the front of Sun racks with silver alloy doors, you need to replace the front hinges.

The Sun cabinet extension can be installed on older Sun Racks that have illuminated logos, but the logo will be partially blocked by the cabinet extension.

Caution - The cabinet extension cannot support the weight of an HVAC system. If you plan to install the cabinet extension on a Sun Rack 1042 with an HVAC rear door assembly, you must install the cabinet extension on the front of the Sun Rack.

Note - If you need to move a Sun Rack in the original shipping carton, you must remove the Sun Rack cabinet extension from the rack. The cabinet extension does not fit inside the top carton.
