Dry Sample Gas Return - Compression fitting for ¼″ OD Tubing. To be connected to
analyzer’s outlet port
Exhaust - Compression fitting for ¼″ OD Tubing. This port may be left open to
atmosphere if the gas being sample is non-toxic and non-corrosive or piped to an outside
location or vent/drain. If the port is connected to a remote drain or vent, do not exceed 10 ft
of ¼” tubing or 30 ft of 3/8” tubing to avoid restriction of the flow.

Start-Up/Shutdown Procedures
Start-Up
1. Once all sample, purge, and electrical connections have been made, the system is ready
for operation. Start with the sample flow meter closed and system and pump power
switches in the “OFF” position.
2. Apply power to the system. This supplies power to the heated line if the heated line
power connector included with the MicroGASS system was used. If the heated line
power was supplied otherwise, turn on power to the heated line.
3. Allow adequate time for the heated line to come up to temperature.
4. Turn on the “System Power” switch. This supplies power to the filter heaters and the
dryer heater temperature controller. After a short amount of time, the temperature
controller will display the dryer temperature.
5. Adjust the system (dryer) set-point temperature to 35°C, or 10°C above the maximum
anticipated dew point temperature, whichever is higher. Refer to the Appendix for the
temperature controller instructions.
