GUTTERS
1. Where it will detect initial snow and ice, position or lay sensor
within 1/4”(6.4mm) of the gutter bottom. For applications
not using the optional Moisture Sensor Cup (Figure 2; see its
manual, p/n 23973), ensure moisture sensing grid (Figure 3) faces
downstream (ambient air temperature sensor facing upstream) to
avoid collecting debris against the grid. Avoid
locations where puddling may occur. Sensor may be fastened to the
fascia with the included mounting clamps, using #8 or #10 screws or
bolts and standoffs as required (not furnished).
DOWNSPOUTS
2. Sensor may be mounted in downspout or on roof edges,
positioned to ensure snow sensing. However, be certain to
protect it from falling or shifting snow and ice masses. Fold cable
back parallel to sensor body and secure with mounting clamps
(or weatherproof tape). Suspend sensor in downspout with
moisture sensing grid facing up (ambient temperature sensor
facing down) as close to the downspout opening as possible.
3. Up to six (6) GIT-1 sensors may be wired in parallel to one
control panel; any sensor will activate deicing. System will remain
activated until ALL sensors are clear of ice, snow and water.
4. Debris collected against the sensor grid will degrade sensor
performance. Locate sensor to avoid falling and blowing debris.
Clean gutters before winter season to assure best operation.
5. To prevent corrosion during off-season months, maintain the
power to the sensor to allow evaporation of moisture from the
sensing grid.
