Installation
Installation of the Model 2020 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 ready to install and prepare for operation.
Carefully unpack the analyzer and inspect it for damage. Immediately
report any damage to the shipping agent.
The four gas fittings that mate with the 1/4 NPT gas ports on the
Model 2020, are not included. They must be supplied by the customer.
3.2 Mounting the Analyzer
The Model 2020 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 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 sup-
plied. The installer must provide two 3/4" NPT and two 1" NPT adapters
and the appropriate sealing conduit.
