INSTALLATION

The site chosen for the installation of the system shall be level, well ventilated, and at a safe distance

from sources of flames, sparks, and excessive heat. The system should not be placed in an area

that may subject it to damage from passing trucks, cranes, or other heavy machines.

system must not be installed under shafting, belting, or other places where oil can drip on it. Refer to

the Manifold ADI for Manifold installation instructions.

a. Be sure to consider all factors when selecting materials.

b. Do not use oil or grease on fittings.

c. Be sure that all fittings are secure and leak tight. Teflon tape should be used on pipe threads.

See Figure 6.

d. Relief valve: The purpose of the relief valve is to protect the autoswitch system and its

components only (Figure 2). If there is pressure sensitive equipment downstream of the

autoswitch system, it is recommended that an appropriately sized relief valve be installed in

the line to protect this equipment.

e. CAPTIVE VENTS: These AutoSwitches are available with internal captive vents installed on all

internal regulator bonnets. These captive vents are used to capture the most probable internal

system leaks, and they are tied into the pipe-away relief valve plumbing so that the leaking gas

can be pipe-away and discharged in a safe area.

WARNING: Equipment failure or misuse may lead to problems such as a release of gas

through the relief valve or regulator diaphragm. The autoswitch box is not sealed and will leak

gas from faulty components. Proper safety measures should be established to handle these

and other component failures.
