Teledyne API Model M701 Zero Air Generator GETTING STARTED
01671H (DCN6051) 3-5
3.5 Power-Up 1. Turn on the front panel POWER SWITCH. SeeFigure 3-2.
2. The front panel power indicator should light.
3. The cooling fan should start immediately.
4. The compressor should start after a few seconds delay. The delay is to allow the
control board to measure the local line frequency.
5. After 30 to 60 seconds, the front panel pressure gauge should read 30 psig.
The Model 701 is now producing clean, dry air.
If the M701 has been unused for several days, it may take 30-60 minutes to achieve
final purity and dryness. It is recommended that the procedure for extended disuse be
followed (Section 3.6, Shut Down, Storage and Transportation).
Remember that the M701 supplies air on demand.
If the application is not requiring zero air, the compressor will increase the pressure in
the storage tank until the “cut-out” pressure is reached and the pressure sensor signals
the control PCA to turn off the compressor.
The pressure in the storage tank will slowly subside as air is used by the Regenerative
Dryer until the “cut-in” pressure is reached and the pressure sensor signals the control
PCA to turn the compressor on again.
Standing H20 will cause corrosion, so if the M701 is to be out-of-use for an extended
period or if it will be transported, the following procedure is recommended.
1. Turn OFF the M701.
2. Wait approximately 1 minute.
3. Turn the M701 ON and vent any accumulated water through the water drain.
4. Turn the M701 OFF.
This procedure will vent any water that has accumulated in the coalescing filter, which
not only helps to avoid corrosion, but also prevents that water from passing into the
M701 in the event that the instrument is inverted during storage or transportation.
