Verify that the regulator operates correctly and verify the temperature with a mercury
thermometer (calibration probe).
16. DEFROSTING.
A decrease in evaporation temperature to below -5 ºC will result in the shutting down of the
compressor by the evaporation security controlling unit, and will remain off until the automatic
reset takes place.
This reset will take place when the differential temperature is reached. During this time, the
fan will operate normally.
When the temperature decreases and defrosting begins, an alarm indicator will appear on
the display.
It is not advisable that the machine operate continuously under these conditions. We recommend
you disconnect the equipment if it will not be in use during prolonged periods of time or under
conditions of low temperatures.
17. TROUBLESHOOTING GUIDE.
The reasons why your dehumidifier may not function properly are mentioned below:
The unit does not start:
Coil contactor does not activate: Verify that it is not burned, and replace it if it is. Verify
the terminals which activate the coil.
Internal thermal switch tripped: Verify the voltage of the line. Verify that the operating
conditions are correct. Excessive compressor consumption. Short circuit in the compressor.
Low pressure switch tripped: Verify the switch operates correctly, replacing it if necessary.
Verify that the fan is operating correctly. Verify the refrigerant charge of the equipment
(refrigerant leak, loss of refrigerant fluids) in order to solve this problem; please refer to the
refrigerant charge section.
Verify that there is sufficient ventilation around coils. Verify that there are no obstructions
in the cooling circuit and eliminate them if there are. Verify that the switch wires function properly
and replace them if necessary.
High pressure switch tripped: Verify that the pressure switch operates correctly and
substitute if necessary. Check the refrigerant charge (excess refrigerant) in order to solve this
please refer to the refrigerant charge section. Check for any obstruction of the cooling circuit and
eliminate the obstruction if necessary.
Verify that there is sufficient ventilation around the condensers.
Defrost cycle: The ambient conditions are not correct (temperatures are too low). The
machine will not operate under these conditions; in this case, the regulator will affect the
condenser, shutting it off until the ambient temperature returns to the minimum required limits for
correct operation.
Low oil level:
Oil stains on the equipment: Check for leaks in the cooling circuit and repair them if
necessary, check the torque on the high and low mini pressure switches, and replace them if
necessary.
