1. Remove 2 screws retaining the interior cover panel and remove panel by
prying out with a thin blade at the top.
2. Select knockouts to be used. Remove the inner (1/2”) knockout by
inserting a screwdriver in the slot and carefully punch knockout loose.
Remove slug. If the 3/4” knockout is required, remove the outer ring with
pliers after removing the 1/2” knockout. Smooth edges with knife if
necessary.
3. Place enclosure in desired mounting location and mark the three mounting
holes.
4. Drill holes for #10 screws, start screws in holes.
5. Place enclosure over screws and tighten screws.
6. Connect conduit hubs to conduit before connecting the hubs to the enclo
sure. After inserting hubs into enclosure, carefully tighten hub lock nut.
Do not over-torque.
7. Wire in accordance with National and Local Codes.
8. Replace interior cover panel and 2 screws.
Grounding: This enclosure is of plastic construction and does not require a
ground connection and does not require bonding in pool applications.
This enclosure does not provide grounding between conduits. When using
non-metallic conduit or cable, connect the ground wires of all cables together
with a wire nut. When metallic conduit is used, use grounding type bushings
and a jumper wire between each conduit.
APPLICATION
