IMPORTANT - Read prior to starting this equiptment. 1.2 Mounting Mount dryer on firm level surface. 1.0 INSTALLATION Dryers are furnished with removable shipping pads. 1.1 Location Remove prior to installation if desired. Dryers may be bolted to the floor if desired. For typical placement in a compressed air system, see drawing at right. - Page 4 1.3 Piping connections 1.4 Electrical connections IMPORTANT - Use copper supply wires only. If welding above unit make certain that Unit is designed to operate on the voltage, sparks are kept from contacting insulation around inlet phase, and frequency listed on serial number tag. and outlet piping.
- Page 5 1.5 Automatic condensate drains Models with electric drains Verify that isolation valves are open. ISOLATION VALVE Verify time settings. After dryer is operating, verify that valve remains open long for all condensate to be ejected from the system. If all condensate is not ejected during valve open time, shorten time between operations.
