2. Mounting the Flow Controller.
The FMA 3200/3400 Series controllers have no particular orientation or
installation requirements so may be mounted in any convenient position.
It is recommended that units be fixed to a suitable substrate using the two
4-40 mounting holes provided.

3. Tubing Connections
All tubing must be clean, dry and purged with clean dry air before
installation of the FLO-CONTROLLER

.
If the gas to be used may contain particles then a filter (20 microns or
less) should be installed upstream of (before) the unit.
When connecting the sensor to the tubing, take care not to over-tighten
the fittings or leaking may occur.
Caution: Only use the fittings factory installed on the unit. If
the fittings are removed the calibration of the unit may be
effected and leaking may occur. If different fittings are required
please contact the Omega Engineering Customer Service
Department for assistance.
