Model: CPRB08XCJ
This manual is for the use of technical personnel entrusted with maintenance. Widetech reserves the right to change this dehumidifier's casing, circuit and parts without notice. The unit operates on 115V 60Hz.
Important Points on Service Operating Safety
Please follow these instructions carefully:
- Unplug the unit to avoid any danger from electric shock before disassembling the unit for repair.
- If there is any sound of the refrigerant circulating when in operation, avoid touching the cooling coils.
- If you need to perform any welding or soldering, be sure you are in a well ventilated area.
- Only a qualified professional should perform any welding on the unit.
- When repairing the unit, the specifications listed in this manual must be strictly adhered to when replacing any components.
- When replacing any electrical components, they should be factory approved units.
- Be sure that any electrical components are properly wired and in place.
Flow Chart for Inspecting and Repairing the Unit
If AIR CONDITIONER WON'T START:
- NO POWER:
- POWER TRIPPED: CHECK THE POWER SWITCH
- PLUG AND SOCKET ARE LOOSE: RE-PLUGING THE POWER SUPPLY CORD
- TIMER FAILURE: TESTING BY ELECTROSCOPE, then CHANGE THE SWITCH
If AIR CONDITIONER WON'T COOL PROPERLY:
- COMPRESSOR WON'T START:
- PROTECTOR FAILURE: CHANGE THE PROTECTOR
- CAPACITOR FAILURE: CHANGE THE CAPACITOR
- REFRIGERANT LEAKAGE:
- WIRING IS LOOSE: RE-CONNECTING
- TROUBLE SHOOTING THE SYSTEM: CHANGE THE AIR CONDITIONER WITH 15 KG/CM² NITROGEN GAS FROM LOW-PRESSURE SIDE AND DETECT THE LEAKING POINT BY SOAP
After detecting leaks: USE OXYACETYLENE AND PLUS 5% SILVER SOLDER TO WELD THE CRACKED POINTS. Then, RUNNING THE VACUUM EVACUATION FOR MORE THAN 15 MINUTES, followed by CHANGE COOLANT AND PROCEED RUNNING TEST.

Appearance and Unit Dimensional
Appearance
Front View: The unit features an Air outlet (to be opened manually), a Control panel, and an Air filter. A Handle hole is also present. Note: Please manually open the air outlet to the desired position.
Rear View: The unit has an Air outlet (Heat exhaust), an Air intake (Condenser), a Remote control storage facility, Castors for mobility, a Water outlet drain, and a Power supply cord.
Unit Dimensional
The external dimensions of the unit are: Width 455mm, Height 617mm, and Depth 333mm.
Operation
Control Panel Description
The control panel includes a Display, Warning Light, Power Control button, Mode Control button, Fan Speed Control buttons, and Timer/Temp Set Controls (Up/Down buttons).
Power Control
The Power Control button turns the unit on and off.
Warning Light
This light indicates when condensed water has accumulated in the unit's internal tank. If the tank becomes full, the warning light will illuminate, and the unit will cease operation until the unit has been drained.
Mode Control
The Mode Control offers three settings: Cool, Dehumidify, and Fan. The currently active mode is indicated by a light.
- Cooling Mode: The indicator light turns blue. In this mode, the unit cools the air and exhausts hot air outside through the exhaust tube. Users can adjust fan speed and air temperature for comfort. Note: The air exchange hoses must vent outside the room when using cool mode.
- Dehumidify Mode: The indicator light turns yellow. Air is dehumidified as it passes through the unit without full cooling. If the room temperature is higher than 25 degrees Celsius, the fan speed can be adjusted; otherwise, it is fixed to "Low". Note: If the unit is to be used primarily as a dehumidifier, do not connect the exhaust hose; allow the warm air to return to the room. Continuous drainage is then necessary and more efficient.
- Fan Mode: The indicator light shines green. Air is circulated throughout the room without any cooling effect. Note: The unit does not need to be vented in Fan mode.
Fan Speed Control
The Fan Speed Control has three settings: High, Medium, and Low. (Note: Page 6 also mentions "Auto" for Fan Speed Control).
Timer
- Auto Turn Off: While the machine is running, press the timer button to select the number of hours until the unit automatically shuts off.
- Auto Turn On: While the machine is in standby mode, press the timer button to select the number of hours until the unit automatically starts running.
Timer/Temp Set Controls
These controls are used for adjusting the timer and thermostat. The default display shows the room temperature. In cooling mode, pressing the "+" or "-" buttons displays and allows adjustment of the set temperature. After 15 seconds, the display reverts to the room temperature. Temperature adjustment is only possible in cool mode. The time can be adjusted between 1 to 12 hours. Note: Pressing both Timer/Temp set buttons simultaneously toggles the display between Celsius and Fahrenheit.
Control Panel and Remote Operation
Remote Control Description
The remote control features buttons for ON/OFF, Mode, Fan Speed (Up/Down), and Timer.
Fan Mode
Air is circulated throughout the room with no cooling. The unit does not require venting in Fan Mode.
Fan Speed Control
The Fan Speed Control offers three settings: Auto, High, Medium, and Low.
Temp Set Controls
Press the "Up" or "Down" buttons to set the temperature. The setting range is from 61°F to 89°F. Note: Temperature setting buttons are invalid when using Dehumidify or Fan Mode.
Timer Setting Control
- When using the timer setting button while the unit is in operation, you can preset a timer for the unit to turn off.
- When using the timer setting button while the unit is on standby, you can preset a timer for the unit to turn on.
- If you press the "ON/OFF" button, the preset timer function will be cancelled.
- The timer setting range is 1 to 24 hours.
