Operation, Continued
CAUTION:
Before resetting any sensor, carefully
inspect the damper, damper actuator, and
sensor. Verify whether or not local
authorities or building managers must be
contacted.
Damage to the temperature sensor will
result in loss of damper control.
WARNING:
Before attempting to reset the EFL by
pressing the Override/reset button, take
the precaution to protect exposed skin as
the EFL will be extremely hot to the touch.
Installation
Figure 2. The EFL and OpenAir Fire and Smoke Damper
Actuator.
WARNING:
The internal/external mounting orientation
or position in the duct will affect the time
and/or temperature the EFL requires to
switch.
NOTE:
Notice the position of the top clip before
attempting to couple the actuator with the EFL
sensor.
Figure 3. Proper Clip Positioning.
Internal Mounting
For internal mounting, the reset button must protrude
through a 3/8-inch (9.5 mm) diameter relief hole
providing operator access for resetting the EFL.
CAUTION:
Failure to provide a relief hole will keep
the reset button pressed against the duct
wall or damper sleeve, and the EFL will
fail to operate as intended.
