Special Mounting

Depending on the geometry, any number of mounting arrangements are correct.
The most common are shown here.
Alternately, the anti-rotation strap can be attached to any Belimo linkage, an
electrical J-box cover plate, or to a pieced of U-channel.
It is important to remember that the ducts are fall-away. The actuator mounting
cannot interfere with the ability of the duct to fall from the damper. The damper must
continue to protect the wall.
See Belimo Mounting Methods Guide for more mounting drawings at

in the documentation tab.

Instructions

An FSLF120 has sufficient torque to handle almost any damper that had a Multiproducts
motor. Only if a leg kit is required should an FSNF120 be used. In some cases where
the Multiproducts had insufficient torque initially, the FSNF is preferred.
1. Disconnect power to damper.
2. Disconnect wiring from motor to thermal sensor wiring box if present.
3. Remove spring, linkage parts, and motor from damper.
4. Test damper to ensure it moves easily from open to closed and back again.
Clean, lubricate (food grade silicone spray or equal – NOT WD40).
5. The Belimo is slightly wider than the old MultiProducts. If the Belimo does not fit
in the space available, then any thermal sensor sheet metal enclosure can be
removed and a 4" x 2" electrical box with open back installed. The box covers
the thermal sensors. This is typically necessary on small dampers.
6. Most applications had shaft springs and fusible links. Some had modern
electrical thermal sensors. See drawings. Negator spring, internal pully, or other
