Caution
Only people who have sufficient knowledge and experience about the product and its
accessories are allowed to start and stop the product.
3.1 Before Starting
Check the following items before performing a trial run of the product.
Installation conditions
Check visually that the product is installed horizontally.
Ensure the product is fixed firmly by the anchor bolts.
Do not place any heavy object on the product, or apply excessive force to the product by the external
piping.
Connection of cables
Check the power supply and ground are correctly connected.
Drain tube
Check proper connection of the drain tube.
Pneumatic piping
Check proper connection of pneumatic piping. Ensure the valves at the inlet and outlet and bypass of the
product are completely closed.
3.2 Start
Start the product by the following procedure.
1) Turn on the main power supply. Then, turn on the switch with lamp.
2) The lamp will light up and the cooling fan will start turning a while later, and hot air will blow out from
the exhaust port.
3) Open the valve at the inlet
and outlet
of the product slowly and fully. Ensure the bypass valve is
completely closed. Check there is no air leakage.
4) The cooling 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. If the evaporation thermometer exceeds the green area
(indicates a higher temperature), refer to “Chapter 5 Troubleshooting”.
5) A while after the compressed air starts being supplied, the drain tube will drain condensate
automatically.
6) Keep operation in that condition.
