1.2 Mounting IMPORTANT: READ PRIOR TO STARTING THIS EQUIPMENT Mount on floor or shelf free from vibration. 1.0 Installation 1.1 Location A. For typical placement in a compressed air system, see drawing. B. Air compressor intake–Locate air compressor so that contaminants potentially harmful to the dryer (e.g. ammonia) are not drawn into the air system. Aftercooler Dryer Oil Removal Filter Separator Compressor C.

1.3 Piping connections 1.4 Electrical connections A. Air Inlet—Connect compressed air line from air source to air inlet. A. Dryer is designed to operate on the voltage, phase, and frequency listed on the serial number tag. B. Dryer is supplied with a cord and plug. Install in a receptacle of proper voltage. Air Inlet Air Outlet NOTE: Refrigeration condensing unit is designed to run continuously and should NOT be wired to cycle on/off with the air compressor.

2.0 Operation 2.2 Start-up 2.1 Minimum/Maximum operating conditions A. Maximum inlet air pressure: refer to dryer serial number tag Energize compressor by positioning the on/off switch in the on (I) position. Compressor on light will illuminate. 2.3 Operating check points B. Minimum inlet air pressure: 30 psig (2.1 kgf/cm2) Check the following on a periodic basis: C. Maximum inlet air temperature: 120°F (49°C) A. Green power on light is illuminated. D.

3.0 Maintenance Sizing 3.1 Condenser coil— Clean off accumulated dust and dirt monthly. Determining dryer capacity at actual operating conditions 3.2 Moisture separator— Replace filter element when pressure drop across dryer is excessive or annually. To determine the maximum inlet flow capacity of a dryer at various operating conditions, multiply the rated capacity from Table 1 by the multipliers shown in Table 2.

TROUBLESHOOTING GUIDE POSSIBLE CAUSE(S) CORRECTIVE ACTION 1. Residual free moisture remaining in downstream pipelines 2. Air by-pass system is open 3. Inlet and Outlet connections are reversed 4. Temperatures surrounding air lines downstream of dryer have dropped below dryers dew point rating 5. Excessive free moisture (bulk liquid) at dryer inlet 6. Condensate not being automatically drained Drain mechanism is clogged or inoperative. Drain line is restricted or frozen.
