Replacing Parts and Equipment
This section describes how to replace worn or failed parts and equipment in the cabinet.
Replacing a Cabinet Door
You can remove the doors from the cabinet for convenience during installation or
maintenance activities, or to replace a door.
Replacing a cabinet door may become necessary if:
A door becomes damaged.
A heat exchanger fails or becomes damaged.
Cooling capacity must be increased to support the addition of a C7 shelf or third-party
equipment (where a factory-installed "blank" door is replaced by a heat exchanger door).
You can replace a cabinet door in the field without impacting service.
CAUTION!
Handle cabinet doors with care to avoid personal injury or
damage to the door. Calix recommends using two people to perform this
task.
To remove a cabinet door
1.
If the door is equipped with an integrated heat exchanger, disconnect the heat exchanger
power and alarm cables.
2.
Disconnect the ground strap from the door by removing the hex nut. Save the nut to
attach the ground strap to the new door.
3.
Remove the nut, bolt, and washer fastening the wind brace to the bracket inside the door
frame.
