1. Select a location in the gutter for the MSG‑1 housing, ensure it is in an area where drainage is unimpeded and that is free
of debris accumulation such as leaves. An area closer to the low end of the gutter slope is preferable. Secure the MSG‑1

is normal, the unit is designed to sit in such a manner. The unit is water‑resistant and may be submerged or immersed in
water in the normal course of operation See Fig.2a,b.
2. Route the MSG‑1 sensor wire along one triangular weave of the heating cable on the roof. At the peak of the second triangle,
attach the sensor wire up the roof, at least 2 feet past the heater wire. Use the clips provided to secure the sensor wire to
the roof. Gently squeeze the coated end of the clip around the sensor wire. See Fig. 3.
3. If the MSG‑1 is located farther than 10´ from the MSC‑1, then the MSG‑1 connection wire must be routed to a junction box
and additional connection wire (up to 500´ of 20 AWG 3 Wire unshielded cable) must be routed from the junction box to the
MSC‑1.
4. Ensure that any connections into a junction box are water‑tight as appropriate.
5. The MSG‑1 is wired directly to the appropriate zone sensor terminal block on the MSC‑1 control panel.
