Conduit enclosing power lead.
If going in to an existing
wall, cut out dry wall and
chisel out bottom plate to
route wires to control.
STEP 3.3:
Bottom Plate Work
Drill or chisel holes at the bottom plate as indicated. One hole
is for routing the power lead conduit and the other is for the
thermostat sensor. These holes should be directly below the
electrical box(es).
STEP 3.4:
Install Power Lead Conduit and Thermostat
Sensor
Power Lead Conduit:
The shielded power lead can be installed with or without
electrical conduit (recommended for added protection
against nails or screws) depending on code requirements.
Remove one of the knock-outs in the electrical box to route
the power lead. If electrical conduit is not required by code,
install a wire collar to secure the power leads where they
enter the box. If conduit is required by code, install 1/2"
(minimum) conduit from the bottom plate up to the electrical
box. For multiple power leads (multiple mats) install 3/4"
conduit.
Thermostat Sensor:
The SunStat sensor can be installed with or without electrical
conduit depending on code requirements. Conduit is
recommended for added protection against nails or screws.
Do not place the sensor in the same conduit as the power
leads to avoid possible interference. Open a separate knock-
out in the bottom of the thermostat box. Feed the sensor
(and conduit, if used) through the knock-out, down through
the cut-out in the bottom plate, and out into the floor where
the heating mat will be installed. If the sensor wire needs
to be secured to the wall stud, wait until after the mat and
sensor are completely installed on the floor.
STEP 3.5:
Rough-in Wiring
Install appropriate 12 or 14 AWG electrical wire from the circuit
breaker or branch circuit source to the SunStat electrical box
following all codes, see Table 5.
Phase 4: Mat Installation
STEP 4.1:
Floor Cleaning
The floor must be completely swept of all debris including
all nails, dirt, wood, and other construction debris. Make
absolutely sure there are no objects on the floor which might
damage the mat wire.
Wet mop the floor at least twice to ensure there is no dirt or
dust. This will allow proper bonding of the mortar and proper
stick of the double-sided tape.
STEP 4.2:
Material
Make sure all of the correct materials have been purchased.
A general list of materials is found at the beginning of this
manual.
Verify the amount of mat supplied is the proper size for the
area to be heated before beginning the installation. Verify
thermostat location.
