minutes period can be chose with big volume of air consumption. Therefore,
5 or 10 minutes period can be chose when the requirement is not so high.
The switch 02 stands for 1 minute period, ON for 2, 12 for 5 and 1N for 10.
2) The red light stands for power on; the green light on the left stands for the
solenoid valve on the left is charged with electricity and the green light on the
right stand for the solenoid valve on the right is power on.

6.4.5 Maintenance
6.4.5.1 Adjustment and Monitoring
No need of on-site adjustment and lubricant.
1) Regularly check the solenoid valves. When the exhausting sounds of the two
towers are louder or different, separate the solenoid valves and check
whether there is dust chocks the passageway or the solenoid valve need to
be replaced.
2) Check whether there is water in the front filter, drain away the water by
pressing the valve on the bottom of the filter cup (or turn on the manual
valve).
6.4.5.2 Semi Year Inspect
1) Semiyearly check after first use is suggested. Estimate the worn condition of
the adsorbent by the following methods: listen to the variable pressure and
regenerative air flow in the drying tower; check whether there is too much
dust and oil at the air outlet and the regeneration discharge port. If there
installs a muffler, remove it and check whether there is excessive pressure
drop, or replace the muffler.
