INTRODUCTION Natural gas (methane) to be tested enters the ODORATOR through the barbed fitting at the gas supply inlet port. Internally, the gas passes through an internal five micron filter to the input of a low pressure regulator. It then passes from the output of the low pressure regulator to the flow metering valve. This valve, located on the top panel of the ODORATOR, is operated by the user. After passing through the valve (when opened), the gas enters the mass flow sensor.
When the ODORATOR is turned on, the user might momentarily notice the letter “L” on the LCD when the READ switch is depressed and held down. If the “L” fails to disappear, it may be an indication of blower speed. The “L” indicates a speed problem, and if on, the Odorator should not be used. When it is time to replace the batteries, “LO BATT” will be indicated in the upper left corner of the LCD when the READ switch is depressed and held down.
WARNINGS AND CAUTION PRIOR TO USE, OPERATOR SHOULD READ ALL PRECAUTIONS, I N S T R U C T I O N S F O R O P E R AT I O N , A N D M A I N T E N A N C E R E Q U I R E M E N T S C O N TA I N E D I N P R O D U C T M A N U A L . NOTE: DO NOT USE THE ODORATOR OR BREATHE IN GAS FROM SOURCES WHICH MAY CONTAIN TOXIC LEVELS OF CHEMICALS, SUCH AS HYDROGEN SULFIDE (H 2S), AS IT COULD BE HARMFUL TO HUMAN HEALTH AND SAFETY TO DO SO.
ANY TIME GAS IS BEING PASSED THROUGH THE ODORATOR THE POWER SWITCH MUST BE TURNED ON. THIS WILL DILUTE THE GAS AT THE EXHAUST PORT AND PREVENT POCKETS OF CONCENTRATED GAS FROM ACCUMULATING. 100% L.E.L. IS APPROXIMATELY EQUAL TO 5% METHANE GAS BY VOLUME IN AIR. AS LONG AS THE REFERENCE C.G.I. READS SAFELY BELOW THE L.E.L., YOU SHOULD NOT HAVE ANY PROBLEM WITH A FLAMMABLE MIXTURE BUILDING UP.

Operation Chapter I OPERATION: This Chapter discusses the proper steps to safely operate the ODORATOR. Also included are procedures for periodic testing and identification of the ODORATOR’s controls. Operation of the ODORATOR WARNING DURING OPERATION, KEEP THE ODORATOR AWAY FROM OPEN FLAMES. INLET SUPPLY SHOULD NOT EXCEED 4 PSIG AND 1/4 PSIG (7 INCHES WATER COLUMN) IS RECOMMENDED. **NOTE** Connect the ODORATOR to the gas supply with a nonabsorbing, odor-free hose such as high grade urethane, PVC, or Tygon.
Operation 2. Connect the sample hose to the gas supply outlet valve and to the ODORATOR inlet port (1). 3. Open the gas supply outlet valve and the ODORATOR flow metering valve for about 10 seconds to purge the air out of the sample hose. 4. Close the flow metering valve. 5. Turn the ODORATOR “ON”. Raise the exhaust port cover. 6. Wait about 30 seconds and then position the nose about 3/4 inch (20 mm) above the exhaust port and sniff the exhaust. The exhaust must be un-odorized. 7.
Operation 12. If the exhaust does not have a readily detectable odor repeat step 11. If the exhaust does have a readily detectable odor, push and hold the read switch down and record the percent gas in air by volume reading as shown on the LCD. This reading is the readily detectable level which should be noticed by the average person’s sense of smell. 13. Close the gas supply outlet valve, the flow metering valve and then disconnect the sample hose from the gas supply outlet. 14.

Operation Chapter II Periodic Test: 1. Every thirty (30) days the ODORATOR should be operated with the power switch on and while not hooked up to a gas supply. 2. Wait about 30 seconds and then position the nose about 3/4 inch (20 mm) above the exhaust port and sniff the exhaust. 3. If no odor is detected, turn the ODORATOR “OFF”. The ODORATOR has not absorbed the odorant and is usable. 4.
Maintenance Chapter III MAINTENANCE: Troubleshooting Chart SYMPTOM PROBABLE CAUSE “LO BATT” appears on Weak batteries. LCD. REMEDY Replace batteries. Motor and LCD will not turn on. RMA Speed Indicator “L” comes on. RMA LCD will not zero with Metering valve open or Close metering valve gas supply line attached instrument problem. or RMA. to the ODORATOR. Odorant detected always Contaminated sample hose or flow system Change tubing or RMA. The RMA process may be found on page 18 of this manual.

Appendix C Appendix C ODORATOR Use at Elevation The ODORATOR works by allowing a metered amount of sample gas to mix with a fixed amount of air and the mixture is then tested by a user for odorant detection. The internal components of the ODORATOR are very stable over changes in elevation. The air that is mixed, however, thins out with increasing elevation and must be accounted for. An elevation change of 3000 feet from the calibration can produce reading discrepancies of nearly 10 % which may be corrected.
Appendix C **Note** The elevation correction chart supports new style Methane ODORATORS only. Instruments manufactured before July 1997, that have not been upgraded or calibrated to a methane reference other than 1.00% will not use the elevation correction charts. Consult the factory for using older style ODORATORS at elevation.
Appendix C Elevation Corrections for the Methane ODORATOR The methane ODORATOR mixes air with natural gas to allow the user to determine the percent gas level at which odorant is readily detectable. As elevation is increased or decreased, the air density changes and must be accounted for. Use the Elevation Change Correction Chart as follows: 1. Use the ODORATOR to determine the readily detectable level per the instructions in this manual. 2.
Appendix C The reading as a percentage between the adjacent chart readings can be used to determine the actual value using the same percentage between chart actuals. The reading of .23 is 30% of the difference in the chart higher reading from the chart lower reading. The lower chart reading and actual will be used as the base or reference. .23 - .20 .30 - .20 = .3 or 30% Therefore the actual value will be 30% of the difference in the chart higher actual from the chart lower actual.
Appendix C Therefore the actual value will be 30% of the difference in the chart higher actual from the chart lower actual. Again, the lower value will be the base or reference. 30% of (.22 - .15) = .3 x .07 = .021 which is rounded off to .02 Since the actual value base is .15, the actual value will be .15 + .02 = .17% gas.
