A heavy-duty kit is available for applications that
have moderate-to-high amounts of moisture in the
compressed-air supply and consists of the basic kit plus
a heat cable to deliver heat to the large pulse valves.
This kit is customer installed and detailed installation
instructions are provided.

5. Drill a 1-in diameter hole in the back of the junction
box. Assemble the power connection kit following
the manufacturer’s instructions.
6. Secure junction box to the collector using two self-
drilling screws.
