1. Mount the SA-1 securely in upright position in an
open space, in direct contact with snowfall pattern
with a .5" (12.70mm) NPT mounting connector.
The unit is water-resistant, but it is not designed
to be submerged or immersed in water. Ensure
that the mounting location is close, less than
2.5 ft (76.20cm) to the electrical junction box.
See Fig. 4a &4b.
2. The SA-1 can be connected to the building power
supply as per Fig. 2 or Fig. 3. Before connecting the
controller to the electrical power supply, consult
the local, state or provincial, and national electrical
code. The electrical code may require a Ground
Fault Protection device to be used.
3. Ensure that all pipe connections are sealed to
prevent any penetration of water inside of conduit
or electrical junction box.
