Figure 2. The EFL and OpenAir GNDxxx.xU/F Actuator.
WARNING:
The internal/external mounting orientation
or position in the duct will affect the time
and/or temperature the EFL requires to
switch.

Internal Mounting
For internal mounting, the reset button must protrude
through a 3/8-inch (9.2 mm) 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.
