CHAPTER ONE
Instructions for Operation
This chapter discusses the proper steps to safely operate the ODORATOR 2. Also included are
procedures for periodic testing and identification of the ODORATOR 2
’s controls.
WARNING:
DURING OPERATION, KEEP THE ODORATOR 2 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 2 to the gas supply with a non- absorbing, odor-free hose or
tubing such as high grade urethane, PVC or Tygon. Tygon tubing is recommended.
**NOTE** Users of the ODORATOR 2 should be selected with due consideration to
smoking habits, colds, and other conditions of health since these factors affect the sense of
smell. It is desirable to select users with an average sense of smell in order to obtain
reasonably consistent results from the use of the ODORATOR 2.
**NOTE** See Figures 1 and 2 on page 7 to reference the top panel layout and rear case view
for the following steps.
**NOTE** All valves must be closed and the ODORATOR 2 turned “OFF”.
Odor Level Testing Procedure
1. Prior to attaching the sample hose, sniff the sample hose and verify no odor is detected. If
odor is detected replace the sample hose.
2. Connect the sample hose to the gas supply outlet valve and to the ODORATOR 2 inlet
port. Squeeze the inlet port lock to disengage while connecting or dis-connecting.
3. Wake the ODORATOR 2 up by holding down the
“PWR” key until the display becomes
active. After booting up the LCD will show a flashing asterisk “ * ” and the present live
reading which will typically be “0.00” with no gas flowing into the instrument. The flashing
asterisk indicates CONDITIONING mode.
4. Open the gas supply outlet valve and the ODORATOR 2 Flow Metering Valve fully for
about 10 seconds to purge the air out of the sample hose and instrument. Do not sniff the
exhaust while conditioning.
5. Close the Flow Metering Valve. Do not force, finger tighten only!
6. Wait about 30 seconds and then position the nose approximately 3/4 inch (20 mm) above
the exhaust port and sniff the exhaust. The exhaust must be un-odorized.
7. Press the
“ * ” key. The ODORATOR 2 will be in ZERO mode with “ZERO” on the LCD.
Press and hold the “ZERO” key until only the last digit of the reading is not zero. Release
