Installation

Installation of the Model 3020T Analyzer includes:

1.Unpacking

2.Mounting

3.Gas connections

4.Electrical connections

5.Installing the Micro-Fuel Cell

6.Testing the system.

3.1Unpacking the Analyzer

The analyzer is shipped with all the materials you need to install and prepare the system for operation. Carefully unpack the analyzer and inspect it for damage. Immediately report any damage to the shipping agent.

3.2Mounting the Analyzer

The Model 3020T is designed for bulkhead mounting in hazardous environments. There are four mounting lugs—one in each corner of the enclosure, as shown in Figure 3-1. The outline drawing, at the back of this manual, gives the mounting hole size and spacing. The drawing also con- tains the overall dimensions. Do not forget to allow an extra 13/8" for the hinges.

Be sure to allow enough space in front of the enclosure to swing the door open—a 16 1/4" radius, as shown in Figure 3-2.

All electrical connections are made via cables which enter the explo- sion-proof housing through ports in its side. No conduit fittings are supplied. The installer must provide two 3/4" NPT and two 1" NPT adapters and the appropriate sealing conduit.
