Page 22: General Recommendations
Instruction book Compressed air prefilter for general purpose filtration, particle removal down to 1 micron, maximum oil carry-over 0.5 ppm This filter provides extra protection of the dryer and extends the lifetime of the high efficiency filter cartridge (4). High efficiency filter, particle removal down to 0.01 micron, maximum oil carry-over 0.01 ppm To remove remaining impurities. -
Page 23: Electrical Connections
Instruction book Provide sufficient space under the filter elements in order to be able to replace the filter cartridges without the need having to disassemble the piping. • Always install a high efficiency filter (4) at the inlet of the dryer. A prefilter (3) is recommended to extend the lifetime of the high efficiency filter. - Page 24 Instruction book • For 115 V AC: connect the supply cable to terminals 2 (line) and 5 (neutral) and place a jumper wire between terminals 2-3 and 4-5: • X3 (freeze contact - P4) If you want to use the feature to “freeze” the regeneration cycle when the compressor runs unloaded, connect pin 1 and 2 of connector X3 with the potential free contact of the compressor (contact closed = freeze).
