Page 5: Heat Pump Principle
Air source heat pump dryer 4. Heat pump principle Working principle: Compressor absorbs low temperature and low pressure refrigerant gas from the evaporator, then refrigerant compressed to high temperature and high pressure gas. The high temperature and high pressure gas goes into the condenser through fan to exchange heat with the air, and condensed into cryogenic liquid in the condenser and give off a lot of heat. - Page 6 Air source heat pump dryer Main menu interface 5.1 Controller operation method 5.2 Lock and unlock At the unlock state, press for 3s until hear “Di” sound, the key is lock. At the lock state, press for 3s until hear “Di” sound, the key is unlock. Timer on-off function It will timer on or off at the setting timer time.

Page 8: Installation Debugging And Running
Air source heat pump dryer 5. When the exhaust temperature > setting protection temperature, open the bypass solenoid valve; close the solenoid valve when less than setting 5 degrees. 5.6 Function mode description 1 Drying mode: Rapid Heating, warming; 2 Cooling mode: Cooling and dehumidification 3 Dehumidification mode: Heating warming firstly, change to Dehumidification after reaching the setting temperature;... -
Page 9: Maintenance
Air source heat pump dryer immediately to adjust the phase sequence. Measure whether the compressor operating current is normal or have abnormal sound. ※ Check whether the unit meets the requirements, run for some time (usually 3 days), then the unit can put into normal use. -
Page 10: Common Failures And Troubleshooting Methods
Air source heat pump dryer Error code sheet: Fault code Fault name Phase sequence protection High pressure switch 1 fault (Protect when Switch off) Low pressure switch 1 fault (Protect when Switch off) High pressure switch 2 fault. Single system don’t have (Show error when switch off ) Low pressure switch 2 fault. - Page 11 Air source heat pump dryer 4. The temp sensor failure: if sensor is failure, it stops all components. 5. Exhaust temperature protection: In (three times / hour), the display does not show the exhaust temperature protection, after the exhaust temperature recovery, the compressor is delayed for 3 minutes to restart. The controller locks the fault when it exceeds (three times / hour), the corresponding compressor is not restart and display fault code.
