GENERAL SAFETY INFORMATION RECEIVING, MOVING, AND UNPACKING PRESSURIZED DEVICES: A. RECEIVING This equipment is a pressure containing This shipment has been thoroughly checked, packed and device. inspected before leaving our plant. It was received in good condition by the carrier and was so acknowledged. • Do not exceed maximum operating pressure as shown on equipment Check for Visible Loss or Damage. If this shipment shows serial number tag.
IMPORTANT: READ PRIOR TO STARTING THIS EQUIPMENT 1.0 INSTALLATION 1.1 Location For typical placement in a compressed air system, see drawing. Air compressor intake – Locate air compressor so that Aftercooler contaminants potentially harmful to the dryer (e.g. ammo- Dryer nia) are not drawn into the air system. Compressor Oil Removal Separator...
1.2 Mounting C. Electrical entry on larger dryers is through a hole in the cabinet. It is located on the right side panel when facing Mount the dryer on a level solid surface. Holes are provided in the front of the unit. Connect power source to terminal the dryer base to permanently mount the dryer to the floor. strip in electrical enclosure as shown on the wiring dia- gram included with the dryer.
2.0 OPERATION If water is present downstream of the dryer, always verify that any condensate drains installed upstream of 2.1 Minimum/Maximum Operating Conditions the dryer are draining properly before attempting to readjust Maximum inlet air pressure: 725 psig (50 barg) the LED setting. Minimum inlet air pressure: 15 psig (1.0 barg) For minimum inlet air pressures that fall between column values, the setting for the lower pressure is recommended.
2.4 Timer Drain Programming Mode Dew Point Drain Interval Temperature Selector Indicator Condensate Draining (Flashes in programming mode) (LED illuminated Drain Interval indicates drain Program cycle setting) 1. Press the “Drain Interval Program” button. The “Conden- sate Draining” LED will start to flash, and the illuminated LED on the “Dew Point Temperature Indicator” will identify the factory setting for “Minutes Between Drain Cycles.” (See Table 1) 2. Press and release the “Drain Interval Selector” button to sequence the “Minutes Between Drain Cycle LED’s” from left to right until reaching your selection. The “Red” LED is not used (Reference Table 2 for “Drain Cycle Intervals”) 3. To initiate the new setting, press the “Drain Interval Pro- gram” button (this will store the new setting and exit the program).
3.0 MAINTENANCE f) Remove and replace complete element. 1) Unscrew the old filter element and discard. 3.1 Daily Also, discard the small O-ring that seals the filter Check separator daily to be sure automatic drain is dis- to the filter assembly head. charging. g) Install new filter element and bowl with new O-rings properly seated to head or bowl (dependent upon 3.2 Weekly dryer size). Blow down separator weekly by pushing test button on h) Connect drain line and replace panel.
4.0 TROUBLESHOOTING GUIDE SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION A) Water downstream of dryer 1. Residual free moisture remaining in Blow out system with dry air downstream pipelines 2. Air bypass system is open Check valve positions 3. Inlet and Outlet connections are reversed Check for correct connection 4.
5.0 REFERENCE 5.1 Sizing Determining dryer capacity at actual operating conditions To determine the maximum inlet flow capacity of a dryer at vari- ous operating conditions, multiply the rated capacity from Table 1 by the multipliers shown in Table 2. Example: How many scfm can an air-cooled model RHP300 handle when compressed air to be dried is at 350 psig and 90°F;...
