After verifying that you have all the components,
select mounting locations and determine how
each component will be placed in terms of avail-
able line voltage, ambient temperatures, envi-
ronmental considerations, convenience, and
serviceability. Figure 1-3 shows a typical system
wiring. A typical system installation is illustrated
in Figure 1-4.
A source of instrument air is optional at the
Oxymitter 4000 for reference air use. Since the
unit is equipped with an in-place calibration
feature, provisions can be made to permanently
connect calibration gas tanks to the Oxymitter
4000.
If the calibration gas bottles will be permanently
connected, a check valve is required next to the
calibration fittings on the integral electronics.
This check valve is to prevent breathing of the
calibration gas line and subsequent flue gas
condensation and corrosion. The check valve is in
addition to the stop valve in the calibration gas kit
or the solenoid valves in the IMPS 4000 or SPS
4000.
NOTE
The integral electronics is rated NEMA 4X
(IP66) and is capable of operation at temper-
atures up to 149°F (65°C).
Retain the packaging in which the Oxymit-
ter 4000 arrived from the factory in case
any components are to be shipped to an-
other site. This packaging has been de-
signed to protect the product.
