Caution
・
Avoid frequent On/Off operation, which can cause troubles.
・
The auto drain used for the product has a structre that closes the valve with air pressure higher
than 0.15MPa. Therefore, until the pressure increase, air will be emitted form the drain outlet at
the begining of opening the IN side valve. Keep in mind that sometime the pressure cannot
increase enough with air compressor that has low dischage flow rate.
・
Avoid using this product under the condition which has sudden pressure/flow rate changes.
Otherwise, drain (condensed water) may flow out to the secondary piping.
3-3 Shutdown
•
Turn off the illuminated switch.
•
The lamp will go out and then, the operation will be stopped. Depending on the condition of operation, hot air
continues to be emitted from the ventilation grille by the cooling fan for a while after turning off the switch,
which is not an abnormality but a process for safety shutdown.
3-4 Cautions about restart
•
One must wait for at least 3 minutes before restarting air dryer after it has been shut down. Failure to do this
may cause safety devices to trip due to over load.
If it is not possible to restart, refer to “Chapter 5 Troubleshooting.”
3-5 Check points before restart
Check following points before you start operation. If any abnormalities occur, immediately stop the operation. Turn off the
illuminated switch of the product and then the breaker to the power supply.
•
There is no leakage of compressed air.
•
Compressed air pressure, temperature, flow rate, and ambient temperature meet the specifications.
•
Drain is being discharged from the drain tube.
•
The pointer of evaporation thermometer is indicating in the green zone.
•
Drainage should not be exhausted from the outlet of the air dryer.
•
There are no abnormal sound, vibration, or smelling.
3-6 Precautions for long-term non-operation
•
If the product will not be operated for more than 24 hours, for example at the weekend, turn off the ILS (Switch
with lamp) or power supply, for energy saving and safety. It is also recommended to release the pressure and
residual drainage inside the compressed air piping
and this air dryer.
•
The residual drainage in the air dryer may splash over the outlet when the operation is re-started, so it is
recommended to install a filter on the outlet of the air dryer.
