Mounting on Suction Line

1.

In cooling units with more than one suction line, place 

the sensing bulb on the common line.

2.

Make certain the bulb is at least 2 ft (0.6 m) from the 

point at which the suction line leaves the cooler. This 

prevents the outside temperature from being transmitted 

to the remote bulb through the copper tubing of the 

suction line.

3.

Place the remote sensing bulb on the side of the 

horizontal suction line between the coil and trap (not on 

the trap).

4.

Attach the sensing bulb to the suction line with clips or 

straps. (See Fig. 17).

5.

Coil the excess length of capillary tubing near the 

L6008A case.

Mounting Surface Mount Models

The L4006H and L6006C are designed for surface mounting 

on piping or tanks. Mount the controller directly on the tank 

surface using the adjustable mounting bracket as shown in 

Fig. 18. The controller can be mounted in any position.

When mounting the L4006H or L6006C on piping, the pipe 

should be 1 in. (25 mm) diameter or larger for accurate 

temperature sensing. Remove any insulation from the pipe. 

Thoroughly scrape off all scale, rust, or paint. Mount the 

controller using adjustable bracket provided. Turn on power.

Wiring

Disconnect power supply before beginning installation to 

prevent electrical shock or equipment damage.

All wiring must comply with local codes and ordinances 

regarding wire size, type of insulation, enclosure, etc.

Figures 19 through 28 show typical hookups.

When wiring a switch equipped with a 1/4 in. (19 mm) tab 

terminal connector, use 18 AWG to 22 AWG (0.8 mm

2

0.3 mm

fully insulated flag receptable connector or equivalent.
