DIFFERENTIAL ADJUSTMENT WHEEL Mounting Remote Bulb Models (L4008A,B,E; L6008A,G,H) ADAPTER CLAMP SCREWS INSERTION ELEMENT The remote temperature-sensing bulb can either be installed in an immersion well (See Fig. 8) that extends into the boiler or tank, or it can be directly immersed in the controlled medium (See Fig. 9). For installations that do not use a well, secure the remote bulb with a bulb compression fitting (See Fig.

L4006,7,8; L6006,7,8 AQUASTAT® CONTROLLERS Mounting Remote Bulb Models For Outdoor Air Sensing These models have a 5 ft (1.5 m) capillary that establishes the maximum distance between the case and the outdoor mounting. Install the bulb on the outside of the building in the shield provided (See Fig. 15) where it can be exposed to representative air temperature, but not to direct sunlight.
L4006,7,8; L6006,7,8 AQUASTAT® CONTROLLERS Mounting on Suction Line 1. 2. 3. 4. 5. In cooling units with more than one suction line, place the sensing bulb on the common line. 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.
