DECK MOUNTED INSTALLATION

A. LOCATION

1. Locate the Junction Box during the system design process to ensure optimal placement and compliance to permit requirements. It is acceptable to install the Junction Box under a PV module. To service the PV system, it is important to have access to the Junction Box after the installation. When installing the Junction Box under a module, consider placing it under the last module in a string or under a module that is easy to lift out of position for access.
2. Place the junction box in a location that will limit contact of the module back sheet under high snow loads, such as near a module frame edge rather than the center of the module.
3. Place the Junction Box in a location that avoids keyways, shingle joints or tabs in the shingle course above the Junction Box. The flashing is designed for use with typical 5”- 5-7/8” asphalt shingle coursing.
4. If utilizing the attic pass-through, do not install the Box directly over a rafter such that the rafter interferes with the conduit coming down from the Box. If you run your wires through the attic, place the Junction Box in an optimal location for access when working inside the attic space.

Avoid Keyways

Avoid Rafters

INSTALL FLASHING

Carefully loosen the shingle glue line at the second shingle course and insert the flashing to the V alignment marks. The flashing should not overhang the shingle, and the marking for UPSLOPE on the flashing should be under the second shingle course

INSTALL JAYBOX ON FLASHING

Align sealing oval of box to align with mating feature on flashing. An EPDM foam gasket is pre-installed to the underside of the junction box to seal the flashing to the box without the need for additional sealant. Secure with supplied #12 x 1-¾” deck screws (2x) until the junction box is pulled tight to the flashing. Do not over-tighten screws to avoid stripping screws in OSB

• If installing pass through fittings, ensure that the JayBox and roof deck are both properly prepared. Complete installation process before attaching the Jaybox to the deck.
  

INSTALL PASS THROUGH FITTINGS

Using a pilot drill, begin drilling out the box at the desired conduit pass through location. It is acceptable to use any location inside the watertight oval for a penetration. Drill through both the box and into the roofing, marking the location on the roof of the clearance hole, transferring the proper drill location to the roof surface.
Remove the box from the roof surface and finish creating conduit mating hole within the box with a step drill bit
Drill pass thru hole with clearance hole saw:

• 2 – 1/4″ for 1 – 1/4″ conduit fitting
• 1 – 7/8” for 1” conduit fitting
• 1 – 5/8” for ¾” conduit fitting
• 1 – 3/8” for ½” conduit fitting

Install conduit fitting to bottom of box provided per conduit fittings manufacturer instructions. Place Jaybox back over flashing and secure to the roof using self drilling wood screws.

WIRING

Install wiring, conduit and fittings per NEC requirements and following local AHJ guidance.
Close lid and fasten with Philips Head Screw Driver, tighten screw 50 in-lbs. Do not overtighten lid screw.
