.
Safety Regulation of Pressure Vessel
As models SHD3075- SHD3240 are applied as

Second Class Pressure Vessel

according to

Boiler and Pressure Vessel Safety Regulation

by legislation of Ministry of labor, they are
accompanied by a certificate for withstanding pressure of the Second Class Pressure Vessel.
During use of this machine, keep this certificate in your possession.
3-2.Cautions at operation
1) Do not use the dryer to remove humidity of except compressed air.
*Breakdown, explosion, or fire may result.
2) Install an earth leakage breaker on the power supply.
*Electric shock may result.
3) Need to earth wiring.
*Causes of an electric shock or a fire.
4) Operate the dryer within specification ranges.
*Operation may stop abnormally, or the product’s service life may be shortened.
*When the working pressure range is low, it is not likely to be able to start.
5) Do not turn on the power switch without enclosures.
*Electric shock or heat injury may result.
6) Do not remodel this dryer.
*Break-down or shorter life time of the product may result. If you did, the warranty is
expired. 
7) Remote start terminal (11-13 or 12-13) is alternate non-voltage input.
8) Do not operate local-remote switch during operation.
*It becomes the cause of stop.
9) Do not touch any parts, wires, terminals or piping in side of the dryer.
*Causes of an electric shock or a fire.
10) If emergency stop occurs during operation, remove the cause of abnormal conditions referring to
the trouble shooting.
*If the emergency stop occurs repeatedly, this may cause the dryer to malfunction.
11) Do not use the dryer for pneumatic caisson shield or respiratory medical equipment.
*It could cause an accident includes injury.
12) Do not use the dryer for transportation devices such as automobile, ship etc.
*Vibration could be a cause of break down of the internal components.
