Installation
Installation of the Model 3020M Analyzer includes:
1. Unpacking
2. Mounting
3. Gas connections
4. Electrical connections
5. Testing the system.
3.1 Unpacking 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.
3.2 Mounting the Analyzer
The Model 3020M is designed for bulkhead mounting in hazardous
environments. There are four mounting lugs—one in each corner of the
enclosure. The outline drawing, at the back of this manual, gives the mount-
ing hole size and spacing. The drawing also contains the overall dimensions.
Do not forget to allow an extra 1
3 /
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.
