INSTALLATION
When Installing this Product…
1.Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition.
2.Check the ratings given in the instructions and on the product to make sure the product is suitable for your application.
3.Installer must be a trained, experienced service technician.
4.After installation is complete, check out product operation as provided in these instructions.
CAUTION
•Disconnect power supply before installation to prevent electrical shock and equipment damage.
•Do not damage or change shape of capsule. Deformed capsule will cause calibration offset.
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.
