Allowing enough de-icing cable lead to reach the electrical junction box begin pressing the narrow edge of the de-icing cable into a track along the edge of the Ray. GOOD PLANNING TIP: Allow the de-icing cable reel to spin and pay out the cable. Do not allow the de-icing cable to coil off the side of the reel or you will have an un-ravelling mess.
CAUTION: Use great care in aligning the cable with the track at the ends of the 3625R14 Rays to assure that the aluminum track wall corners do not dig into the heat trace cable outer jacket. Moisture intrusion through such damage will ultimately cause cable failure.
One side of two tracks cabling is completed. Notice the size of the free cable loop between two rays in the center of the jig. This free loop allows for the clearance needed to install the cable through the clamping collar flutes later on in the installation process.
As the de-icing cable is installed the loop requirements at the center drain area and the extended end of the 3625R14 become apparent. Notice the half round loop of cable at the end of the 3625R14 Ray. This is the minimum size loop to prevent heater cable jacket damage during cabling process.
Notice the additional Ray added as an extended arm to the 6RDDJ22. This feature is handy to reach some singular remote source of icy water such as scupper drainage from a higher roof. Due to direction and distance independence any quantity of 3625R14s may be used in such an extension as long as the maximum single run length of de-icing cable is not exceeded.
With the exception of making the last center loop of de-icing cable much longer(e.g. two foot per leg of the loop for drain on an interior heated building) to de-ice the down drain this 6RDDJ22 is now ready for installation.
