INSTALLING THE CABLE IN GUTTERS AND DOWNSPOUTS
1. Run the heating cable in the gutters and into downspouts, end the

cable in a loop at the bottom of the downspout and then run the cable
back up the downspout using a tie wrap to fasten it as shown in Figure
9. Permanent attachment of the cable to the gutter bottom is not
necessary. Do not leave the end of the heating cable pointing down at
the end of the downspout, double back as shown.

2.Use King SRK15 downspout brackets at the transition of the gutter

and downspout to protect the cable from fraying, to prevent damage
due to sharp edges and to provide a strain relief as shown in Figure
10. Refer to the SRK15 kit instructions for more installation details.

3. Route and secure cable with care to avoid mechanical damage during

installation or maintenance from such things as ladders, etc.

ATTACH THE WARNING LABLES
1. Two warning labels are provided with the SRP cable kit to indicate the

presence of electric deicing and snow-melting equipment on the
premises. One label should be attached at the electrical outlet cover
and the other label must be posted at the fuse or circuit breaker panel
feeding the outlet circuit. Labels must be clearly visible.

CHECK AND INSPECT THE INSTALLATION
1. Prior to plugging the deicing cable into the outlet, check the entire

length of the cable for mechanical damage such as nicks and cuts in
the outer insulation and any potential thermal damaged which may
have occurred if cable was exposed to excessive heat.

2. Use a megohmmeter to test each circuit according to the instructions

in the “Heating Cable Testing and Maintenance” section of these
instructions.

3. Junction boxes should be inspected for water and for evidence of

previous water damage. If moisture is present, the box should be
restored to a dry condition and the cause of the water intrusion should
be investigated and eliminated.

4. Test the ground fault circuit to be sure it is functioning properly. If

malfunctioning, replace prior to energizing the system. Functionality of
over-current protection devices such as circuit breakers or fuses
should be checked as well.

STARTING THE SYSTEM
1. King recommends that the heating cable system be tested per the

“Cable Testing and Maintenance” section below.

2. Plug the heating cable into a 120 volt ground-fault protected outlet.
3. Check the circuit breaker to the outlet to verify there is power to the

cable.

HEATING CABLE TESTING AND MAINTENANCE
1.Make sure that gutter and downspouts are free of leaves and other

debris annually prior to the winter season.

2. Using a 2500-Vdc megohmmeter, check the resistance between both

of the power prongs on the plug and the ground prong after installing
the heating cable. Minimum reading should be 1000 megohms.

3. Record the original values for each circuit, and compare subsequent

readings taken during regular maintenance to the original values.

4. If the readings fall below 1000 megohms, replace the cable with a new

unit. Do not attempt to repair the cable.

WARNING

Fire and shock hazard. Damaged heating cable can cause
electrical shock, arcing, and fire. Do not attempt to repair or
energize damaged heating cable. If damaged, immediately
remove it and replace with a new cable.
