hydrocarbons. Regulator outlet pressure
should be set at 5 psi (35 kPa). Reference
air can be supplied by the reference air set
of the IMPS 4000.
If using an IMPS 4000, refer to the IMPS
4000 Intelligent Multiprobe Test Gas Se-
quencer Instruction Bulletin for the proper
reference air connections.
Do not use 100% nitrogen as a low gas
(zero gas). It is suggested that gas for
the low (zero) be between 0.4% and
2.0% O . Do not use gases with hydro-
2
carbon concentrations of more than 40
parts per million. Failure to use proper
gases will result in erroneous read-
ings.
b. Calibration Gas
Two calibration gas concentrations are used
with the Oxymitter 5000, Low Gas - 0.4% O
and High Gas - 8% O
the Oxymitter 5000 connections.
2-5 PNEUMATIC INSTALLATION (FOR OXY-
MITTER 5000 WITH SPS 4000)
Do not use 100% nitrogen as a low gas
(zero gas). It is suggested that gas for
the low (zero) be between 0.4% and
2.0% O . Do not use gases with hydro-
2
carbon concentrations of more than 40
parts per million. Failure to use proper
gases will result in erroneous read-
ings.
Upon completing installation, make sure that the Oxymitter 5000 is turned on and operating
prior to firing up the combustion process. Damage can result from having a cold Oxymitter
5000 exposed to the process gases.
During outages, and if possible, leave all Oxymitter 5000 units running to prevent condensa-
tion and premature aging from thermal cycling.
If the ducts will be washed down during outage, MAKE SURE to power down the Oxymitter
5000 units and remove them from the wash area.

a. Calibration Gas Connections
Locate the 1/4 in. calibration gas fittings on
the SPS 4000 manifold (Figure 2-2). Con-
nect O calibration gas 1 (high calibration
2
gas) to the HIGH CAL-GAS IN fitting and O
calibration gas 2 (low calibration gas) to the
LOW CAL GAS IN fitting. Ensure the cali-
bration gas pressure is set at 20 psi (138
kPa).
b. Reference Air Connection (Optional)
If the reference air option (which includes
the reference air flowmeter, pressure regu-
lator, and necessary tubing and fittings) is
used, connect the instrument air to the 1/4
in. fitting on the reference air pressure
regulator (Figure 2-2). The pressure regu-
lator is factory set at 20 psi (138 kPa). Re-
adjust by turning the knob on the top of the
regulator to obtain the desired pressure.
If the SPS 4000 does not have the refer-
ence air option, connect the reference air to
the Oxymitter 5000 as instructed in para-
graph 2-4.
