8 INSTALLATION AND OPERATING INSTRUCTIONS
E. PRODUCT SAFETY FEATURES
1. Automatic Defrosting
To ensure the unit operates and performs as stated, the unit has
been designed with an Automatic defrost function as frost can be
produced on the surface of the evaporator in low temperatures.
When the temperature sensor detects the room temperature has
dropped to 16°C or lower, the Auto Defrost function will start and
the DEFROST symbol
will be displayed on the LCD screen.
The unit compressor will run for 25 minutes on dehumidification
mode and then the fan will run at high speed in 7 minute cycles to
defrost the unit.
Note: The dehumidification symbol will disappear.
2. Protection Of Extremely Low & High Temperature
Unit is built with a room temperature sensor that will automatically
shut off the unit when the ambient temperature is either less than
or equal to 0°C or greater than or equal to 40°C. When sensor
is activated there will be a continuous warning beeper which will
beep 3 long and 2 short beeps and the corresponding temperature
(either 0°C or 40°C) will be displayed on LCD screen.
Note: Unit will not be operable when sensor is activated, to restart
unit, unplug unit and restart again.
Note: If unit is shut off due to protection of extremely low & high
temperatures, the unit memory function will not operate, unit will
reset at default setting.
3. Failure of Humidity & Temperature Sensor
When the connection wire between the humidity and temperature
sensor is disconnected, the humidity icon
will blink and
0°C and 0% RH will display on LCD screen. Unit will switch into
continuous dehumidifying mode.
If the temperature evaporator sensor becomes open circuit or
short circuit the DEFROST light
will start blinking.
Unit will operate in a humidifying and defrosting mode,
dehumidifying for 20 minutes and then defrosting for 5 minutes.
Note: If the temperature sensor malfunctions, the unit will
continue to work but at a lower efficiency.
4. Compressor Protection
If the unit malfunctions during the operation of the unit and the
compressor fails, the compressor will switch off. Wait a minimum
of three minutes to reoperate unit.
5. Memory Function
If the power is cut off during the operation of the appliance, the
unit will memorise the working mode automatically.
Once power is restored to the unit, the appliance will restart and
continue working at the last set working mode.
