b) Placing Concrete
A plastic cover is provided with the socket to prevent it from
being accidentally filled with concrete. The plastic cover is the
same thickness as the sensor flange.
This allows the finished surface of the concrete to be toweled
flush with the cover. The cover must be installed prior to placing
the concrete. Also insure that the mounting plate drainage hole
remains unplugged once the concrete has cured. (See Figure 7)
Install the socket directly on top of gravel in order to
provide good drainage. If that is not possible, please
ensure that you drill a hole through the bottom of the
socket for proper drainage of water for the optical snow
sensor to function. (See Figure 6) If this is not done, it will
void the warranty of the snow sensor.
Never use the wire conduit as drainage. This can damage
the sensor wire resulting in damage to the control and/or
sensor.
c) Installing the Sensor
Once the snow melting surface is finished you can install the
snow/ice sensor. Clean any excess debris from inside the socket.
Fish the snow/ice sensor wire through the pre-installed pipe.
Make sure to leave a little bit of slack in the wire (see figure 7).
Once the snow/ice sensor is properly inserted into the socket put
the four screws back in place to secure it.
Take special care to align the screw holes from the snow/
ice sensor to those on the socket. Once the sensor is
pressed into place prying up the sensor to line up the
holes will result in damage to the sensor and, potentially,
the socket.
2. Remote Sensor Location
The optical nature of the snow/ice sensor allows for mounting
somewhere other than the slab (i.e. a roof or fence post). This is
possible, but take special care that it is not mounted in an area
where the surroundings cause an abnormal amount of snow fall.
Paving stones or equivalent should be installed with a
remote sensor.
When remote mounting the sensor an external slab sensor
must be used in order for the control to be able to read
the slab temperature. The temperature sensor on the
snow/ice sensor will no longer be used.
