Product Applicability

This bulletin applies to the following products:

E / F Series

For systems that are mounted to a 2 – 2.5” square post or 2.38 – 2.88” round post.

Background

In 2018 Carmanah set out to develop a combined mount that will work with both the E / F Series engines and for square/round posts of varying sizes. This was released 2018 Q4 and is known as the cast mount. This robust mount will simplify the ordering process with a single mount that works across multiple products and mounting styles.

In rare cases, the cast mount may not thread properly onto the solar engine or signal head hex nipple. When this occurs, the cast mount may encounter resistance and both sets of threads could become damaged. There are two standard methods of installation, depending on the configuration:

Solar engine integrated into signal head: cast mount threads onto a hex nipple at the bottom of the signal head. The solar engine then secured to the signal head via a hex nut and serrated lock ring (threaded nipples highlighted in yellow)
Solar engine not integrated into signal head: Cast mount threads directly to the nipple on the solar engine (thread nipple highlighted in yellow)
