Compressed air is a highly dangerous energy source.
Never work on the dryer when the system is under pressure.
Never direct the compressed-air outlet or condensate drain hoses at persons.
The user is responsible for the proper maintenance of the dryer. Non-observance of the instructions in
the "Installation" and "Maintenance, troubleshooting, spare parts and dismantling" chapters leads to the
expiration of the guarantee. Improper maintenance may result in dangerous situations for the personnel
and/or the device.
Danger!
Supply voltage!
Contact with non-insulated parts carrying supply voltage involves the risk of an electric shock resulting
in injuries and death.
Only qualified and skilled personnel are authorised to run electrically-operated devices. Prior to undertaking
maintenance measures at the device, the following requirements must be met:
Make sure that the power supply is switched off and that the device is off and marked for maintenance
measures. Please also ensure that the power supply cannot be re-established during the works.
Prior to carrying out maintenance works at the dryer, switch it off and wait for at least 30 minutes.
Caution!
Hot surfaces!
During operation, several components can reach surface temperatures of more than 140°F (60°C). There is the
risk of burns.
All components concerned are installed inside of the closed housing. The housing must only be opened
by certified skilled personnel.
Some components can reach high temperatures during operation. Avoid any contact until the system or the
component has cooled down.
