SETTING UP INSTRUCTIONS

IMPORTANT: Place dehumidifier in the upright position. When transporting a dehumidifier to site, allow the dehumidifier to stand for 30 minutes before switching ON. This is necessary to allow the refrigerant system to stabilise and avoid system damage
SETTING UP THE DEHUMIDIFIER: Operate the dehumidifier in an enclosed area, as this creates a drying chamber. Close all doors, windows or areas that open to external areas, to maximize the dehumidifier’s water removal efficiency. Keep traffic through the drying chamber to a minimum. Place the dehumidifier in the centre of the room away from walls and furnishings. DO NOT allow the airflows to be obstructed.

DRAINAGE: The dehumidifier pump connects to a plastic drainage hose. The hose is stored on the back of the appliance. Uncoil the entire hose ensuring there are no kinks or restrictions and place the unattached end into a water vessel or run to outdoors. Ensure that water which runs to outdoors does NOT create a slip hazard. Water vessels MUST be checked regularly where used.

SETTING UP INSTRUCTIONS

The drainage hose must be positioned to be less than 15 ft. above the unit. Failure to do so may cause water backup in the pump resulting in leakage.

CONTROL PANEL

  1. ON/OFF control: Press the ON/OFF control to turn the unit ON or OFF.
  2. Operating Indicator: The indicator light has 3 states: (1) off when power is not available, (2) flashing when power is available and the unit is OFF, or when the control panel is locked and the unit in ON, and (3) on when the unit is ON.
  3. UP and DOWN controls: Press and hold the UP and DOWN controls to set the desired humidity level from 99% to 26% or select “CO” for continuous operation.
  4. TIME control: Press to temporarily change the display to show current operating hours and lifetime hours, based on minutes. For example, if the display shows “0000: 50”, it means the unit has operated for 50 minutes. To view current operating hours, press the TIME control once. To view lifetime hours, press the TIME control twice. To reset the current operating hours, turn the unit OFF or press and hold the TIME button for 5 seconds. After 10000 hours of operation, the lifetime hours wrap around to 0000:00.
  5. Humidity and Time Display: The display has 3 modes: (1) off mode where the display is blank when the unit is OFF, (2) humidity mode where the left 2 digits show the desired humidity level and the right 2 digits show the environment humidity level, and (3) time mode where the display shows current operating hours and lifetime hours. After 10 seconds, the display reverts from time mode to humidity mode.
  6. PURGE control: Press the PURGE control to manually initiate a pump purge cycle. The pump will turn on for 40 seconds
  7. Purging Indicator: The indicator light turns on when the pump purge cycle is active. The pump automatically initiates a pump purge cycle of water when the reservoir is full and when the unit is turned OFF.
  8. Defrosting Indicator: The indicator turns on when the unit detects ice on the coil and turns off when the ice has melted. During defrost, the blower pulls air from the environment across the coil with the compressor turned off.
    • Note: The totally working time can not be deleted, if the time is beyond the range of LED showing time, it will be deleted and recounted from the start.

OPERATING INSTRUCTIONS

  • A: Operations for general use:
    • To turn the unit ON, press the ON/OFF control. To protect the compressor, there is a 60-second startup delay when the unit is turned ON.
    • To set the desired humidity level, press and hold the UP and DOWN controls.
    • To turn the unit OFF, press the ON/OFF control. To drain any water in the pump reservoir, a pump purge cycle is automatically initiated when the unit is turned OFF.
    • Attention: DO NOT switch the power OFF by disconnecting at the main socket outlet. To avoid water spillage; DO NOT move the dehumidifier for at least three minutes after turning the power OFF.
  • B. Control panel lock: To lock the control panel, press the TIME control and PUMP control simultaneously for 2 seconds. To unlock the control panel, press the TIME control and PUMP control simultaneously for 2 seconds.
  • C. Maximum performance: To maximize drying performance, increase the distance between the air inlet and air outlet by attaching a 7″ diameter or larger lay flat duct to the air outlet.

Maintenance CLEANING THE AIR FILTER

Ensure the dehumidifier is turned OFF and the plug is removed from the power socket before maintenance is carried out. The working performance of the dehumidifier will be greatly reduced if the filters become blocked.

  1. Remove the air filter as shown above.
  2. Vacuum any debris from the air filter.
  3. Using luke-warm water and a mild detergent, wash the air filter and allow to dry.
  4. Once dry, reinstall the air filter.

Maintenance REPLACING THE BATTERY

  1. Remove the screws in the four corners of the control panel.
  2. Once the screws are removed, carefully lift the control panel to access the PCB.
  3. Refit the control panel onto the PCB.
  4. Refit the four screws.
