Emerson SL-2G Benutzerhandbuch

1.  Please fully read these instructions prior to installation and 

operation.

2.  Determine a suitable mounting location for the SL-2G 

control. The control must be placed in a location that is 

within 4’ of a 120VAC electrical outlet and within 8’ of the 

pipe being heated and controlled. 

3.  Mount the SL-2G to a rigid support such as a wall by way of 

the rear mounting slots.

4.  The SL-2G thermostat control is suitable for dry location  

(in-door) installations only. 

5.  Carefully uncoil and straighten the sensing wire/sensing bulb 

and attach it to the outer surface of the pipe being heated. 

The bulb on the end of the sensing wire must be located in 

an area that is experiencing the same freezing or damaging 

cold temperatures that the pipe is experiencing.  The sensing 

wire must not be kinked or compressed during installation. 

When used with the ILH product, the sensing wire must be 

secured to piping with tape, and not with devices such as 

cable ties or pipe clamps, as these will damage the sensing 

wire. The sensing wire must be protected from damage. 

Sensing wire damage will result in improper control of the 

heating cables and may result in frozen pipes and the risk of 

fire or electrical shock.

1.  The SL-2G thermostat control is designed to energize  

ILH heating cables when ambient temperatures drop  

below the set value. By controlling heating cable operation 

with the SL-2G, energy consumption is minimized.

2.  The bulb on the end of the sensing wire senses the 

temperature. If the temperature of the bulb drops below 

the pre-set temperature value the cable will energize, and 

remain energized until the sensing bulb senses temperatures 

above the pre-set value.

3.  The SL-2G can be tested for functionality by submerging the 

sensing bulb in ice water for 10 minutes; the GFCI receptacle 

will be energized.

4.  Disconnect the power to the SL-2G during the summer 

months.

5.  At the beginning of the heating season and monthly during 

operation, inspect the SL-2G control and its connection to 

the electrical power source. Similarly, check the GFCI on a 

monthly basis. Testing of the GFCI is dependent upon the 

temperature of the sensing bulb.

6.  Plug the SL-2G power cordset into a 120 VAC receptacle. 

The lighted plug on the cordset will illuminate indicating that 

there is power being supplied to the SL-2G control. Turn the 

SL-2G control knob to the maximum setting of 25°C (77°F). 

The GFCI receptacle indicator light should be off. If the GFCI 

receptacle indicator light is illuminated press the “Reset” 

button on the receptacle, the GFCI receptacle indicator 

light should then turn off. If the GFCI cannot be reset, then a 

fault exists. Do not attempt to bypass the GFCI. Bypassing the 

GFCI will result in the risk of fire or electrical shock.

7.  Set the desired protection temperature for your application 

by adjusting the control activation temperature between  

2° C and 25°C (36°F to 77°F).

8.  Plug in your ILH heating cable to the GFCI receptacle on the 

front of the SL-2G control.

      a)  If the ambient is below 21°C, turn the thermostat 

control knob to the maximum setting; the GFCI will be 

energized. Push the “TEST” button on the GFCI recptacle; a 

“click” should be heard and the receptacle indicator light 

will turn on. Push the “RESET” button on the GFCI recptacle 

to reset the power (the indicator light will turn off).

      b)  If the ambient temperature is above 22°C, you will need 

to “cool down” the sensing bulb to test the GFCI. It is 

recommended to wait until the bulb is below 21°C as 

in step a), however if this is not possible you will need to 

submerge the sensing bulb in ice water for 10 minutes and 

then follow the instructions as described in a) above. 

6.  The GFCI will not be affected by power interruptions.

7.  Discontinue use and remove any unit that has been 

damaged or has deteriorated for any reason. 

8.  Other conditions to look for are chewing by animals, water 

damage/corrosion or physical abuse.
