Mounting with Guard Bracket
Mount the bulb in the guard bracket as shown in
Fig. 16. Locate the bulb and bracket combination,
in freely circulating air, in the controlled area. With

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.

The L4006H and L6006C are designed for sur-
face 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 pip-
ing, 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 control-
ler using adjustable bracket provided. Turn on
power..
