Low-limit Temperature Switch

Catalog Number(s) 1414-CLM20AHDAB,

Install the Low-limit Temperature Switch

The switch can be mounted in any position. Avoid locations subject to excessive
vibration. On manual reset model, position control to permit convenient access to
the reset button . Use three mounting holes in rear of case for flush mounting to
duct or other flat surface. Install capillary element in horizontal serpentine pattern
across duct on downstream side of the coil so it is exposed to areas where low
temperatures will occur. Do not kink or apply excessive force to the capillary
element. Fasten capillary at sufficient points to prevent damage from air movement
or vibration.
