INSTALLATION

2.1 GENERAL

Proper installation techniques will ensure highest performance and also minimize measurement errors. The Remote Set Regulator should be mounted in a location that is not subject to radical temperature extremes, vibration and shock. See Section 6 Specifications for environmental operating conditions.

This section describes the mechanical mounting arrangements of the Regulator and explains the technique of bringing in wiring via electrical conduit.

The installation procedures described herein are furnished as a guideline and cannot cover all possible variations. All deviations from the installation procedures described herein are at the discretion of the user.

2.2 MOUNTING

The overall mounting dimensions for the unit are given in Figure 2-1. Be sure that the selected site has sufficient clearance to remove the Regulator cover and access internal switches and terminals. Choose the appropriate mounting arrangement below as required

2.2.1 Two-Inch Pipe Mounting

Refer to the overall dimension of Figure 2-1 for views of the universal pipe mounting bracket. For this type of installation, the bracket is assembled to the Regulator using three screws. Select the desired set of bracket holes for either vertical or horizontal mounting pipes.

Once the bracket is mounted, position the assembly next to the pipe as required and install the u-bolts from the hardware kit into the appropriate bracket holes. Install nuts on the u- bolts and tighten them until the instrument is self-supporting.

2.2.2 In-Line Mounting

In-line mounting can be used when the pressure line and electrical conduit provide sufficient strength to support the weight of the unit. This type of mounting should never be attempted on lines constructed of soft or low-strength materials. In-line mounting is also not recommended for non-secured lines subject to excessive vibration or hammering.

Once the desired location has been selected, cut the pressure pipe and install proper fittings (1/4 in. NPT male) to mate with the two pressure connection ports on the Regulator. It is recommended that unions and shutoff valves also be installed in each line to allow an easy disconnect for maintenance or troubleshooting operations.
