Mounting
Install controller in any convenient location. Make sure that the
sensing bulb reaches the system to be controlled. The ambient
temperature must not exceed 125
°
F (52
°
C) in the area where
the controller is installed.
Install the sensing element where it can sense the average
temperature. Avoid sharp bends or kinks in the capillary tubing
that can affect the accuracy of the controller. Carefully coil the
excess capillary tubing and leave it directly beneath the
controller.
The 130883 Mounting Plate furnished with TRADELINE®
models allows the control to be mounted in existing mounting
holes.
Duct Installation
Position the sensing bulb in the duct to sense the average air
temperature. Avoid mounting the bulb close to hot pipes,
cooling coils, etc.
The 107324A Bulb Holder is available for suspending the bulb
in a duct. See Fig. 2.
