1. INSTALLING THE STEP TREADS ONTO THE STEPS:

• Clean all debris from the step. Debris could damage the heating elements.
• Place a step tread on the front edge of the first step. Be sure to position the heater so the nose is snug against the vertical side of the step and the wiring is as far to one side as possible. Refer to step 3 below: You can run the wiring harness off the side edge of the step, if you wish, in order to completely remove it from the walking surface.
• CEMENT STEPS ONLY: Hold the step tread in place on the step. With a 3/16" masonry drill bit, drill six small holes through the step tread into the cement step using the pre-drilled holes located on the step tread as a template. Remove the step tread and place the plastic cement anchors into each of the six drilled holes. Reposition the step tread over the holes. (Old or worn out cement may compromise the integrity of the installation. Consult a licensed mason if you have any questions.)
• Screw the entire step firmly into place with the screws provided. Be sure the tread is secure.
• Follow this installation procedure on each step.

2. RUN THE LOW VOLTAGE WIRING HARNESS THE LENGTH OF THE STEPS, AND FIRMLY PLUG EACH TREAD IN TO IT

• Run the 12/2 low voltage wiring harness on either the left (see Diagram A) or right side of your steps, as you determined when you placed your order.
• Place the harness as far to the side edge of the step as possible so people won’t trip on it or damage the low voltage plugs. If you wish, you can run the harness assembly off the side edge as shown in Diagram A. Adjust the harness to ensure the step tread and harness plugs will attach to each other easily.
• Plug the step treads into the wiring harness plugs.
• **Please see note below for further information on this system and transformers.

3. INSTALL THE TRANSFORMER:

• Install the transformer included with your system according to the instructions found in the transformer box or on the inside of the transformer lid.*
• Be sure to place it within reach of the low voltage wiring harness.
• Connect the wiring harness to the transformer (see transformer instructions).
  For safety questions consult a licensed electrician. Obey all local electrical codes.

* The step heating system you have purchased includes a transformer with appropriate watts to power the number of heated step treads in your package. Transformers are available in varying watts and each has a limited number of heaters it can power. You must know this in case you ever decide to replace the transformer in this package or increase the number of steps connected to it.

If you should ever need to replace a transformer, or heater, you should know:
A 9"x30" step heater uses 60 watts of electricity, the same as a 60-watt light bulb. To determine the number of watts the transformer needs to power your system, multiply 60 times the number of heaters you wish to use. (An example is given in the chart below.) Do not exceed the transformer’s maximum watt rating when installing the system. 12 volt outdoor lighting transformers are compatible with this system. Be sure all transformers are U.L. approved

** Note: The 25' of 12/2 wiring harness provided can support up to five 9x30 heated treads or four 9x36 heated treads. You can use up to a maximum of 25' of 12/2 cable for either configuration.

TO OPERATE THE STEP HEATING SYSTEM:

• Plug in the transformer and wait ten minutes.
• Check to see that the Warm Welcome® step treads are warm (they won’t be hot) by placing your hand on the tread surface.
• If the treads are warm a good electrical connection was achieved.

ALL HEATERS HAVE BEEN TESTED TO OPERATE. If a heater is not operating, an electrical connection was not achieved somewhere in the system. Do the following:

• Check to ensure the power supply (transformer) is plugged in and is on.
• Check your wiring connections at the transformer
• Be sure the step tread plugs are connected firmly to the wiring harness.

PROPER USE OF YOUR NEW STEP HEATING SYSTEM
The heaters do not need to be turned on all the time. If you know snow is forecast, or if lowering temperatures might turn wet steps to ice, switch on your step heating system before these conditions occur.

Your step heating system is designed to prevent accumulations of snow and ice on your steps. If snow accumulated because the step treads weren’t turned on:

• Switch on the transformer.
• Wait ten minutes for the step heaters to warm.
• Brush off the excess snow or ice with a stiff brush or broom.

For your safety, each time you use the step heaters, check to ensure they are turned on and working properly before stepping on them.

To get extra long life out of your Warm Welcome® step heating system, install it in the fall and remove it in the spring.
