Chapter 4 Operation/ Shutdown
4.1 Check points before operation
Before trial operation, check following points.
Installation state
By visual inspection check that the product is installed horizontally.
Make sure the product is fixed properly with anchor bolts.
Do not place heavy obstacles on the product and add unreasonable loading by piping and so on.
Connection of cables
Check that the power cable and grounding cable are connected correctly.
Drain tube
Drain tube should be connected correctly.
Air piping
Confirm that the piping to the compressed air is correctly connected. Check that the IN and OUT
side of the product and bypass piping valves are completely closed.
Ball valve
Ensure that the ball valve of the auto drain is opened.
Cooling water piping
Make sure that the cooling water pipes are correctly connected. Ensure that the valves on the
water pipe are open and the cooling water flows.
4.2 Operation
Start operation according to the procedure below.
1) Turn on the main power supply breaker. Then turn on the white switch (operation switch).
2) Operation LED (green) is ON.
3) Open the IN and OUT side valves slowly. Ensure the bypass valve is completely closed.
Confirm that there is no air leakage.
4) The compressor may continuously operate depending on the compressed air status. The evaporation
thermometer indicates green band. When the evaporation thermometer is over the green area, refer to
Chapter 6 - Troubleshooting.
5) After supplying compressed air for a while, the drain will be discharged from the drain tube
automatically.
6) Continue the operation.
Only someone who has enough knowledge and experience about the product and
incidental devices should operate or shut down the product.
CAUTION
- Frequent switching ON and OFF leads to malfunction.
- The auto drain is normally open and the valve closes when the air pressure is 0.15MPa or
more. When the IN side valve starts to open, air bleeds from the drain outlet until the
pressure reaches 0.15MPa. The pressure may not reach 0.1MPa when the air compressor
discharge flow rate is small.
- Dehumidified drain may flow into the secondary piping if there is sudden change of
pressure or flow speed. Do not use the product where those condition is present.
CAUTION
