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 on a level surface.

Make sure the product is fixed properly with anchor bolts.

Do not place heavy objects on the product or 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.
4.2 Operation
Start operation according to the procedure below.
1) Turn on the main power supply breaker. Turn on the switch with lamp.
2) The operation lamp turns on. After a moment, the cooling fan will rotate, and hot air will be exhausted
from the ventilation outlet.
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 fan keeps starting and stopping depending on the compressed air and ambient temperature
conditions, but the compressor keeps operating continuously, and the evaporation thermometer stays
within the green area.
When the refrigerant pressure gauge indicator is in the area higher than 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
- Frequently switching ON and OFF leads to malfunction.
- The auto drain is normally open and the valve closes when the air pressure is 14.5psi (0.1MPa)
or more. When the IN side valve starts to open, air bleeds from the drain outlet until the
pressure reaches 14.5psi (0.1MPa). The pressure may not reach 14.5psi (0.1MPa) when the air
compressor discharge flow rate is small.
- Dehumidified drain may flow into the secondary piping if there is a sudden change of
pressure or flow speed. Do not use the product where these conditions are present.
