Description
High Limit Switch used in many gas & electric heaters. Commonly found on older Hurlcon and Astralpool heaters.
Used on outlet for some early Hurlcon & Purex Minimax heaters. Automatic Reset.
Important Information:
- These are an Extremely Important Safety feature found on heaters. They must be replaced when necessary.
- When installing, make sure both male & female thread are clean. We recommend lightly lubricating the thread, and *gently* screwing them in, as the thread shaft is thin brass. Dirty threads, or over-tightening can break the shaft. This is not covered by warranty.
