The FAAC 428403 Manual Release Assembly is a genuine spare part designed for FAAC gate openers in the 413 / 415 series, compatible with both 24VDC and 115VAC versions (including 415, 415 L, 415 L LS). This assembly allows you to manually disengage the drive mechanism via a key, enabling gate operation by hand, which is essential during power failures or for maintenance purposes. Built to FAAC’s standards, it ensures reliable performance and full compatibility with existing factory components.
Power Down: Before starting, disconnect or turn off the power to the gate opener (make sure both primary/supply voltage and control board power are off) to avoid electrical hazard.
Access the Manual Release Location: Open the FAAC 413/415 operator cover to locate the manual release assembly (part #428403). Refer to the parts diagram for the 415 (found in FAAC manuals).
Install or Replace: If replacing an old or damaged manual release, remove the fasteners securing the current assembly. Replace with the new 428403 assembly, aligning the release lever/cam with the mechanism inside. Ensure that any gaskets or seals are properly seated if applicable.
Secure Fasteners: Tighten screws/nuts to the manufacturer-specified torque (check FAAC manual for torque values). Make sure parts are secure and there is no loose movement in the assembly.
Test Manual Release: With the key, operate the release lever. Confirm that the motor drive disengages, and you can open/close the gate manually. Make sure the assembly re-engages correctly when released.
Restore Power & Test Full Operation: After installation, reconnect power and run the gate opener through its full cycle (opening and closing) to ensure no binding, no missed limits, and that the automatic operation resumes correctly.
Always disconnect power before any installation or maintenance.
Use only the correct FAAC manual release key; using incorrect tools may damage the release cam mechanism.
Do not force manual operation if the assembly is not fully disengaged—it may damage internal components.
Ensure the unit is correctly aligned; misalignment can lead to premature wear or failure.
Keep the assembly clean and protected from water ingress; moisture in mechanical parts can cause rust or seizure.
If the unit shows signs of excessive wear, replace it; a failing manual release might compromise safety in power-failure scenarios.
Use original FAAC spare parts to ensure fit, durability, and warranty compliance.
Periodically test manual release function (e.g. yearly) so you’re sure it works in an emergency.
Lubricate the lever or pivot if needed with FAAC-approved lubricant to ensure smooth action.
Always keep a spare key for manual release in a secure but accessible location.
Check the FAAC operator’s manual to see any specific maintenance notes for your model (413 / 415 / LS versions).
