    inlet and outlet valves, and close the bypass line valve. Allow the unit to run for one hour with airflow. Adjustment to the hot gas bypass valve or expansion valve may be necessary at this time to obtain the desired refrigeration suction temperature (this is not under warranty). See Figure 2. Figure 2: Adjustment of Hot Gas Bypass and Expansion Valve.

    C) range. In a 50 C PDP, the refrigerant temperature is lowered to the 40 C range. This cold liquid refrigerant flows into the air-refrigerant heat exchanger where it cools the compressed air, and evaporates into a cold vapor. Vaporized refrigerant flows to the accumulator (R235 or ADR120 and larger).

    Micro-Monitor: The Pioneer Micro-Monitor is standard in models R75/ADR40 and larger (optional in smaller sizes). The dryer operation and performance are shown at a glance by selecting the desired reading. Maintenance To maximize system performance and reliability, the following maintenance procedure is required: Air and water cooled condensers must be inspected and cleaned periodically.
  • Page 9 discharge pressure until either the compressor motor fails or the compressor cycles on high pressure cut- out control. If the dryer cycles for any reason, turn it off and contact factory; allowing it to cycle on high pressure will burn up the compressor motor. Because of higher pressure and electrical voltage, only qualified service personnel should work on the equipment.

    TROUBLESHOOTING PROBLEM REMEDY 1. System bypass open. Close bypass valve and open inlet/outlet valves 2. Excessive air flow. Check rated output capacity of air compressor; a larger system may be needed. 3. High inlet air temperature. A larger system or after-cooler may be needed (consult factory) 4.
