IMPORTANT ADDITIONAL INFORMATIONS

ELECTRONIC BOARD (SA)

This is the control board of the dehumidifier that along with the probe ST1 and the two sensors RT1 and RT2, verifies the
working conditions of the appliance itself. In case of missing information (e.g. a defective probe), the board will stop the
appliance and the alarm light will stay steady on.

ANTIFROST PROBE (ST1)

This probe is located on the aspiration tube of the compressor, where it mesaures
the gas temperature. With gas temperatures below -6°C, the electronic board sets
the appliance on antifrost function. The compressor will stop and the blu alarm light
blinks fast. When the gas temperature has risen again to above +7°C the appliance
resume dehumidifying.

AMBIENT SENSOR (RT1)

This sensor measures the ambient temperature.

SECURITY SENSOR (RT2)

This sensor is located at 1mm. from the resistance R19.
Confronting the temperature readings from RT1 and RT2, the microprocessor of
the electronic board can detact a malfunction of ventilation and change the
ventilator speed and if needed eventually stops the appliance in alarm mode.

INSTRUCTIONS FOR MAINTENANCE ON ELECTRONIC BOARD

When you replace the electronic board, do make sure that the distance between the
sensor (RT2) and the resistance (R19) is 1mm.

INSTRUCTIONS FOR MAINTENANCE ON THE ON/OFF SWITCH

For spark protection the ON/OFF switch is surrounded by a heat shrinking sleeve,
which ones removed or damaged is not to be reused or to be repaired.

Having to exchange the ON/OFF switch you therefor have to exchange the

INFORMATION ON THE VENTILATOR
The ventilator has only one working speed, but automatically it is forced
on a slower speed during the 3 minutes compressor delay phase or when
problem on the normal working function.
