Where do I install the DCM-PRO Factory Joint?
Make sure that ALL heating cable, including factory joint, is positioned under the final floor finish. Be sure to completely embed the cable and joint in a modified polymer thin-set or leveler.
Tape the factory joint to the floor at the start point. Ensure that the joint lays flat on the floor.
Additionally, install the joint under the floor covering and cover with polymer modified thin-set or a self-leveling compound. Installation may required a channel to recess the joint into the sub-floor to accommodate the extra height of the joint.
Lastly, do not bend the joint at the point of entry into the conduit as this may damage both the factory joint and/or the heating element within. Secure the joint to the floor using a piece of duct tape over the cable before and after the joint, but not over the joint itself.
