Operating instructions

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.
The GIT–4 requires an RCU–2 Remote Control Unit which is included. The RCU–2 provides remote control
and monitoring of the GFEP function. It also permits operating the snow and ice melting heaters for a fixed time at
temperatures below 38 ˚ F (3.3˚ C).
Supply Voltage Options
The GIT–4 provides jumper-selected supply voltage options of 120, 208 through 240, and 277 volts. Selecting
the proper supply voltage is very important. An incorrect setting may destroy the GIT–4 or render it inoperative.
The GIT–4 operates from the heater supply voltage.
Relay (Contactor) Contact Ratings
The relay (contactor) provides a Form A (SPST) contact rated for up to 26 amp AC heater loads at voltages at
or below 277 volts.
Safety
Any installation involving electric heater wiring must be grounded to earth to protect against shock and fire
hazard. Suitable ground fault detection and interrupting systems must be in use at all times to reduce shock and fire
hazard and to protect equipment.
Electric wiring to heating elements must be installed in accordance with Article 110.3B, Article 210.8(A)(3),
Article 250.4(A), Article 426.4 & 28, Article 725.55 and all other applicable sections of the National Electric
Code (NFPA 70), local electrical codes, and any third party standards. Follow the installation instructions
contained herein and those provided by the heater manufacturer. If you have questions concerning the installation
contact Customer Service for assistance.
The use of a GIT–4 with integral GFEP satisfies the NEC requirement for GFEP on each branch circuit
connected to the snow and ice melting system. Clearly label each circuit breaker with its function. This is vitally
important when there is more than one point of disconnect.
Make certain that the heater shield is properly grounded as required by the NEC.
Installing the Sensor
Mount the sensor as low as possible in the gutter about a foot upstream of the downspout. For proper operation,
the heating cable must be close to but not touching the sensor. A separation of
1
/
2
" (1.3 cm) to 1" (2.5 cm) is ideal.
Orient the sensor with the temperature sensor facing upstream and the moisture sensor toward the down spout. Use
the supplied plastic mounting straps and gasketed #10 fasteners to secure the sensor in the gutter via
3

" drilled
holes through the gutter. See Figure 1.
