J-COUPLE
The J-Couple assembly is mounted in the exhaust duct collar of each hood, threaded through a
UL/ULC listed hood penetration fitting in the center of the duct collar. The J-Couple wiring is
terminated in a special factory supplied J-Box. Where there are multiple hoods, the J-Couples are
connected in series. The last J-Couple assembly requires an EOL plug to complete the control circuit.
