Maximum Wire Lengths for Snow / Ice Sensor 090
The following table shows the maximum wire length for the Snow / Ice Sensor 090.
The “Max Added Length” column shows the additional length of wire that can be added to the
090's existing 65'.
All splices must be:
• soldered individually
• heat shrinked individually
• located in a dry junction box, preferably inside the building
For a more robust connection and long term signal quality, it is recommended to heat shrink the
cable jacket.

Snow / Ice Sensor Socket 091
The Snow/Ice Sensor Socket 091 is designed to provide a mounting solution
for the Automatic Snow/Ice Sensor 090 or 094.
It is intended to be installed directly into a concrete slab when the slab is poured,
so that the 090 or 094 can be installed into it once dry.

Fittings: Sioux Chief ½” Copper PEX Crimp
ASTM F1807 Crimp™
American Society for Testing and Materials (ASTM)
Standard Specification for Metal Insert Fittings Utilizing
a Copper Crimp Ring for SDR9 Cross-linked Polyethylene
(PEX) Tubing and SDR9 Polyethylene of Raised
Temperature (PE-RT) Tubing.
F1807 Installation
3. Install PEX fitting into tube end.
5. Compress tool perpendicular to
tubing run. Compress only once.
Remove defective connections. Use
a gauge to assure a proper joint. Test
completed joint.
1. Cut tube at 90-degrees. Do not
crush OD of tubing with cutters.
Hint: Slightly rotate cutter during
blade engagement.
2. Install PEX Crimp Ring onto OD
of tubing.
4. Position ring over sealing barbs
of the fitting. The ring should be
positioned approximately 1/8" to
1/4" from the end of the tube.
F1807 fittings can be made from various listed materials.
See ASTM standard for acceptable brass alloys. Assure
your fitting is made from a listed material.
F1807 systems use a copper crimp ring to compress
around a fitting.
Connection is made by positioning a crimp ring over a
fitting’s sealing barbs and compressing it into position.
Fittings are reusable if barbs remain undamaged.
ASTM F1807 Crimp Installations & Application Problems
13 www.siouxchief.com
F1807 Application Problems
Crimp joint made with an improperly calibrated tool - not
providing enough compression to joint.
Ring compressed multiple times possibly developing a
leak path.
Crimp Tool did not engage the Crimp Ring over the entire
surface of the ring.
Tube not cut squarely – ring not compressing tube for a
secure seal.
Fitting not inserted completely into tube end.
Ring not placed over sealing barbs of fitting. Ring too far
forward or too far back & not fully over sealing barbs.
