STEP®SNOWMELT SYSTEM
STEP®Snowmelt is a heating solution to melt snow and ice on entrances, walkways, driveways,
ramps, patios, etc. The snow melt system eliminates shoveling snow and protects pedestrians
from slippery ice or snow covered driveways and sidewalks.
STEP®Snowmelt systems consist of thin, flat and flexible heating elements that operate on low
voltage (AC or DC) and are custom designed for each individual application. These durable,
lightweight heating elements can be stapled or nailed through as long as the two embedded bus
braids on each side of the element are not penetrated.
STEP®Snowmelt heating elements are powered by a 24V low voltage AC Power Supply or DC
Controller. The heating elements, which can be cut to size on site are available in different
widths and protected by a chemically, inherently inert and dielectric insulation. This liner
protects against physical damages and aggressive materials and allows heating elements to be
installed under concrete or selected other surfaces.
STEP®Snowmelt heating element is made of a homogeneous, semi-conductive polymer, which
by nature is self-regulating. This self-regulating, positive temperature coefficient (PTC), Nano-
technology allows them to heat with maximum power in cold environments and use less
electricity as their temperature increases. This minimizes power consumption and reduces
operating costs by as much as 60% compared to conventional electric cable systems.
BENEFITS
STEP®Snowmelt is a flat, flexible and thin heating element.
The heating element can be cut to length at the jobsite.
The polymer material can be penetrated without affecting the conductivity, but the two
conductors on each side must not be penetrated.
The element is strong and durable.
STEP®Snowmelt has the ability to self-regulate - as the material gets warmer, less
electricity passes through the plastic - therefore it is extremely energy-efficient.
The element acts on its whole surface as a sensor and cannot overheat.
This heating system is very versatile and can be used for residential, commercial and
industrial applications.
Avoids shoveling snow, and keeps pedestrians safe.
Low operating costs compared to alternative snow melting systems.

PRODUCT SPECIFICATIONS
CONSTRUCTION
The STEP®Snowmelt heating elements MEP-30-70W and MEP-23-80W are designed to prevent
ice and snow on walkways and driveways. The element is constructed of two parallel bus braids
embedded in semi-conductive PTC polymer.
A polymeric dielectric liner is applied at the time of manufacturing so that the liner is thermally
fused to the heating element. This creates a heating element that features a solid and
homogeneous construction which is chemically inert.
The 12” and 9” wide elements normally come slotted, unless specified with no slots.
APPLICATION
Snow and Ice Prevention

INSTALLATION
1. PLAN
Design system, and make a layout. For guidance, see attached layout and wiring
diagram.
When deciding on a snowmelt system it is essential to decide on the purpose of the
system and how effective the system should be. Should the ground be completely dry
or is it acceptable with some snow slush on the ground shortly after a snowfall.
ASHRAE classifications split snowmelt systems into three groups:
oSnow free ratio 0:
Designed not to melt snow while it is falling, but
afterwards.
oSnow free ratio 0.5:
50% of snow is melted while falling, the rest afterwards.
oSnow free ratio 1:
All snow and ice is melted while falling.
When designing a snowmelt system it is essential to know the area conditions;
snowfall days, temperature, surface type, heat loss to ground, atmospheric loss and
perimeter insulations. These are some of the parameters needed to create snowmelt
solutions according to expectations.
An on demand deicing system may be favorable in places with few snowfall days.
Areas with frequent snowfall may benefit from the thermal bed concept which is a low
power deicing system that is switched on prior to frost and kept energized all winter.
Wherever underlying soils are susceptible to frost, pavements will suffer damaging
effects from frost heave and spring breakup. There are different techniques to reduce
frost action, such as:
oRemoving frost-susceptible soil and using thick base courses to spread the load
during spring thaw.
oProviding adequate drainage for free water through ditching.
oPlacing a layer of insulation in the embankment section to keep sub-grade soil
temperatures above freezing. Maintaining the soil above freezing temperatures by
placing heating elements in the upper soil or pavement section.
Installation should conform to local building codes, ordinances, and trade practices.
2. INSTALL
Heating elements should be installed in ambient temperatures between 40oF and
140oF (4oC and 60oC).
Lay the STEP®elements onto an even layer of granular material and secure them in
place to prevent displacement of panels.
Avoid heating elements to overlap or touch each other. DO NOT puncture the bus
braids.
Apply subsequent lifts, pavement or soil layers taking care not to damage the heating
elements.

11 | P a g e

INSTALLATION
3. CONNECT
Connect extension wires to the heating element according to the drawing and electrical
diagram. If fail safe wiring is required, refer to instructions in the diagram “Fail Safe
Wiring”.
Determine wire gauge versus load and length of wire from the element to the power
supply. The wire gauge for a circuit fully loaded is 10 AWG by default but if the
distance is longer than 14 feet, connect the extension wires to a terminal block and
then route to the power supply using higher gauge wires as shown in Wiring Diagram.
Insure that wiring is done according to the National Electrical Code.
Route the wires through the ground in a conduit. Connect wires in parallel to the 24
volt AC power supply or DC controller. Use only stranded tinned copper wires, and do
not twist wire ends when connecting to the interface board in the supply.
Distribute the load evenly; the maximum load per circuit is 450 watts.
The power supply must be installed in a well-ventilated area and wired in accordance
with the NEC.Place the power supply vertically using rubber bumpers between the
back heat sink plate and wall for better cooling and quiet operation.
Connect the line voltage to a two-pole on/off switch. Use stranded wires from the
switch to the power supply.
To make the system operational, connect the three signal wires COM, TRG and ~24V
from the interface board terminals to the thermostat. The system will switch on when
the thermostat asks for heat.
The heating elements must be measured and the amp draw noted by a certified
electrician before being covered. The warning label must be placed in the service panel
and the caution label on the electrical box, or on the low-voltage power supply.
NOTE: This system is low voltage and the heating elements must NOT be grounded.
4. COVER
The heating elements should be placed on top of gravel and compacted sand. Then
secured in a way that the elements do not shift position when concrete is poured.
If a reinforcement mesh is used, take care that the no conductive material is in direct
contact with the heating elements.
Do not pour more than 8 inches of concrete over the heating elements. If more is
needed consult manufacturer or a thermic engineer.
NOTE: These installation guidelines are general in nature. Specific project information is
provided by the distributor.

INSTALLATION
MAKE THE CONNECTIONS
• Make a strain relief connection by
punching three holes with a hand drill
or punch tool. Weave a stranded
tinned copper extension wire in the
holes. Strip the wire end, and join the
wire with the bus braid in the STEP®
tinned copper crimp connector. Crimp
the joint using the required crimp tool.
Using components not recommended
by the manufacturer will void the
warranty.
• Expose the bus braid by making an
angled score in the plastic, front and
back, and along the bus braid above
the angled score with a utility knife.
Bend the element where the cuts are
made and pull offthe corners to
remove the surplus of plastic. Make
sure that the bus braid is not cut or
damaged. Should this occur, re-cut
the element and re-strip the bus braid.
Repeat on the other side.
• Seal all connections by using the
required sealant tape on the connector
side of the element. Cut two pieces of
tape slightly longer than the width of
the element. Enclose the wire joints
and strain relief connections with the
two pieces of tape and firmly press the
pieces together while overlapping the
element to form a flat and smooth
splice. If the opposite end is not
connected use the same vulcanizing
tape to seal the open end of the
element.

INSTALLATION
SYSTEM DESIGN
STEP®Thermal Bed system is designed for continuous duty on 24 volts and will melt ice or snow
provided the substrate has been continuously heated. This maintenance heat keeps the ground
temperature constant and reduces the expansion and contraction in substrates.
Place a low water absorption and high compressive strength insulation, e.g.
“Styrofoam*Hi” or equivalent, vertical along the walls of a trench or foundation to
protect against frost penetration.
Care should be taken to prevent vehicles and heavy equipment from bearing directly
on the vertical insulation.
Make sure that the insulation is properly butted together to avoid the transfer of heat
/ cold migration and transfer of moisture.

FAIL SAFE WIRING
• The Fail Safe Wiring method is used whenever there may be a risk of damaging the bus braids
located on each side of the heating elements.
• Supplying electricity from both ends of an element eliminates the possibility of arcing from a
damaged bus braid.
• Not only is this wiring method safer, it reduces voltage drop and makes the element more powerful.
