Installation and Direction for Use:
- In the event that the thermostat is employing contact temperature sensing, its cover shall be adhered to the installation position of a controlled appliance.
- The cover shall show no cave-in or deformation resulting in operating temperature variation or bad influence on other performances.
- No excessive force shall be applied to working parts, to prevent them from defects such as cracking base, distorted terminal and wire lead coming off.
- The plastic envelope must be kept intact in the course of installation and usage.
