B) Prior to installation, the dryer and the compressed air system are to be depressurized and disconnected from the electrical main supply. C) The user is responsible for safe operating conditions. Parts and accessories must be replaced if inspection shows that safe operation cannot be assured.
D) For air cooled dryers, clean the air condenser as soon as it’s dirty or clogged. E) For optional water-cooled condensers, use only clean water and install a water filter if needed. Use water counter flow to clean condenser if need. F) Check the trouble-shooting list in case of maintenance troubles. G) Check operating pressures, temperatures and time settings after maintenance. If operating and safety devices function properly, the air dryer may be used.
down to dew point and enters the separator where condensates are collected. The outgoing chilled air is then warmed up in the economizer by the hot incoming air. b) The condensates are collected after centrifugal separation and drained out through the automatic trap. c) As long as the compressed air temperature does not drop below dew point, there will be no condensation in the air circuit. 5) Refrigerant compressor Being of the hermetic type, it requires no servicing.

3.2. During Operation Regularly check the digital temperature controller ESD3 or dew point indicator on dryer. B) Start up and shut-down Warning: Avoid leaving the dryer off when compressed air is still flowing through it. C) Starting for the first time or after a long stop 1) Set the rotary switch to “I” This preheats the dryer and turns the drain system on. It is recommended to leave the dryer power on permanently so the crankcase heater runs continuously.

Restore a free flow of water condensate. Check water evacuation. Bypass system is open Check the valves Important: Bypass piping should be installed around the dryer so the dryer can be isolated for service without shutting down the air supply.

Be sure that dryer is working lower than design conditions. A high ambient temperature may cause the refrigerant system to operate at higher than normal pressures. Results will be a higher than normal evaporator temperature.
