When enough frost forms the defrost thermostat will initiate the timed defrost cycle The cycle periodically turns off the compressor while allowing the blower to run The frost is melted by the air that the blower draws through the cooling coil The defrost cycle is automatic and designed for optimum performance above 50 F If the unit is used in an area that is below 50 F for more than 2 hours adjustment of the defrost timer is recommended to improve performance see Sec 2 10 DRYING TIP Air s ability to absorb moisture from wet surroundings and the Phoenix 300 s ability to remove moisture from that air is greatly improved at higher temperatures We recommend that the area to be dried be heated to over 70 F if possible Less drying time will be required and efficiency will improve To adjust the defrost timer 1 Unplug the unit 2 Remove the front cover 6 screws 3 The timer is fastened to the right inside panel Every fourth peg around the dial is pushed out from the dial center except one section with 5 pegs out in a row See figure 1 Each fourth out peg represents 15 minutes of compressor off time during every hour that the unit is in the defrost cycle 4 To improve performance below 50 F the compressor off time must be increased to 30 minutes per hour to allow the frost to completely melt To do this push the pegs out from the dial center so that the pegs alternate with 2 toward the center th
