Caution
No one but someone who has enough knowledge and experience about the
equipment and incidental devices should operate or shut down the equipment.
3.1 Check points before operation
Before a trial running, check following points.
•
Installed Condition
By visual inspection check that the equipment is installed horizontally.
Make sure the product is fixed enough with anchor bolts.
Do not place heavy obstacles on the equipment and add unreasonable loading by piping and so on.
•
Wiring Connections
Power cord, and the earth should be connected firmly.
•
Drain Tube
Drain tube should be connected correctly.
•
Air piping
Check that the compressed air piping is connected correctly and flushing can be done as described in 3.2.
Check that the compressed air inlet and outlet of the dryer, and bypass piping valves, are completely closed.
Also, check that the compressed air inlet and outlet piping is insulated.
3.2 Operation
Start operation according to the procedure below.
(1) With Valve 2 (below) closed, open Valve 1 to perform flushing of the outlet piping.
(2)Turn on the main power supply breaker, then turn on the ON/OFF switch.
(3) The operation lamp and temperature control PV value and SV value light up. After a moment, the
cooling fan will rotate, and hot air will be exhausted from the upper ventilation outlet.
(4) Set the outlet air temperature of the dryer. (See 1.2 for setting method.)
* Depending on the operating conditions, the outlet air temperature and air cleanliness will stabilize in
around 10 minutes.
If the outlet air temperature does not stabilize, set the PID value by auto tuning (See 1-3).
