Description The computerized UL and CUL Listed GIT–4 automatically controls gutter and downspout snow and ice melting heaters. It is safety tested to Standard 873 for Temperature Indicating and Regulating Equipment. The GIT–4 includes the GFEP (ground fault equipment protection) required by the NEC. The GIT–4 consists of sensor and control assemblies connected by a 12' (3.6 m) cable. The sensor meets the NEC (National Electrical Code) low voltage Class 2 requirement for wet locations.

Installing the Control Lethal voltages are present within the control enclosure during operation. Some installations may require two points of disconnect. Tag all circuit breakers off during installation or service. The GIT–4 comes factory set for 277 volt operation. A jumper located in the control must be changed for 120 or 208 through 240 volt operation. See Figure 2. An incorrect setting may destroy the GIT–4 or render it inoperative. The control comes connected to the sensor with 12 feet (3.

9. Remove the ammeter from the GIT–4 controller. 10. Replace the cover on the GIT–4 controller. 11. Apply power to the snow and ice melting system. This may require two points of connection. Checking the system function requires moisture and a cold source. If the temperature is already below 38°F (3.3°C) then simplying appling a small amount of moisture (such as a damp, clean paper towel) should energize the heaters. If the temperature is above 38°F (3.
