Reset at Roof Level
1.
Feed out a minimum of 14’ of cable at lower winch to create slack
.
2.
At upper winch, remove spent fusible link from the system by removing the retaining
lock nuts. Reseat the spring attached to the lever arm to the winch housing. Pull the
lever arm up, bring the two screws close enough to set the new fusible link in place and
secure with the retaining lock nuts. (Only if thermally released)
3.
Flip the ratchet at upper winch up to the engaged position.
4.
Wind upper winch until the cable is taught.
5.
The thermal release is now reset. Vent can be winched closed by lower winch.
Installation Instructions for Manual Winch
1.
Once the smoke vent has been roofed in and is fully installed the manual winch option
can be set up to operate the doors to open and close.
2.
Determine the desired location for the floor level winch (shipped loose) and mount it
to a suitable structure.
