Operating introduction

Power on

Plug in the appliance to the mains supply and press the ON/OFF button, it will start and it will start to operate.
When powered on, the unit will start to dehumidify. The compressor will activate after five minutes.

If the appliance is turned off via the ON/OFF switch and not unplugged from the main supply, it will start up again in the same mode.

Power off

While the appliance is operating, press the ON/OFF button to turn it off.

Humidity setting

To change the humidity level, press the HUMIDITY button, each time the button is pressed, the display will change as follows 40%~50%~60%~CONT~40%. After setting the humidity level, the display will revert to the current moisture level detected by the internal sensor.
When the ambient humidity is 2% lower than the set humidity, the dehumidifying action will stop and the fan will stop for 1 hour; the unit
will not detect the humidity during this period. After 1 hour, the fan will start and work for 3 minutes during which time the ambient humidity is detected. When the unit detects that the ambient humidity is 2% higher than the set humidity, it will start dehumidifying and the fan returns to its set speed.

When operating in the dry clothes function, the machine is running in CONT status.

Timer
To start the timer function, press the TIMER button. Each time the button is pressed, the timer will cycle 2H, 4H, 6H, off . For 2H, 4H and 6H the respective light will illuminate.

Memory function

If the unit is turned off via the ON/OFF button, when turned back on again it will resume from the function it was turned off in. Note that if the timer was set or if the unit was in the lock mode, these settings are not stored.
If the mains power is disconnected while the unit is operating, it will restart automatically when it is reconnected. The unit will restart in the mode/function it was operating in prior to the main disconnection.

Water tank full auto-stop function

When the water tank is full, the unit will stop operation, the and the unit will bleep to remind you to empty the water tank. To reset, remove the water tank, empty and replace. When the empty water tank is put back into the unit, it will restart. Note that the compressor will take about 5 minutes to operate.

Auto defrost

If the unit is used in a low-temperature environment, the internal evaporator may be covered by frost. To make sure the machine operates normally, the machine has an auto-defrost function. Should
the internal sensor detect a temperature of ≤-1 °C the machine will
enter auto-defrost function. That means it will run continuously in the dehumidification mode for 30 minutes, then the machine will start the defrost cycle, the DEFROST light will illuminate, the compressor will stop and that fan will operate at high speed.
When the temperature of the evaporator is ≥2 °C and the unit has been in the defrost mode for 10 minutes, the auto-defrost mode will turn off and the compressor will turn on. At this point, the unit will start to dehumidify and the DEFROST light will turn off.
While in the defrost mode and the temperature of the evaporator is ≥0 °C for two minutes, the defrost function is canceled.

Laundry mode

To enter the laundry mode, press the HUMIDITY button for 3 seconds. When in laundry mode all 4 humidity indicator lights will illuminate. While in the laundry mode, the fan will operate at 1000rpm and the dehumidification level is set to the continuous mode. After 6 hours in this mode, the fan will continue to run but at a lower speed of 800rpm. This ensures that the dehumidifier runs more effectively once the clothes have lost most of their moisture.
The laundry mode can be canceled at any time by pressing the HUMIDITY button for 3 seconds or by powering the unit off by the ON/OFF button.
When drying clothes, they will dry quicker if the room is smaller and the air is directed as shown in picture.
If the appliance is in the timer mode prior to entering the laundry mode, the laundry mode will continue until the end of the set time and stop. If the timer button is pressed while in the laundry mode, the unit will continue in the laundry mode until the end of the set time and stop.

Compressor protection function

Should there be a problem with the unit causing the compressor to stop, the compressor will turn off for 5 minutes.
Normally the compressor will restart after 5 minutes, if it does not unplug the unit for an hour and try again. If it still does not start, call for service.

High/Low-temperature protection function

If the unit detects that the ambient temperature is 0°C≤ or ≥40°C, it will shut down. In this condition, both the POWER and DEFROST lights will flash.
While in the mode the ON/OFF button makes a sound but does not work.
To reset the unit, unplug the power and restart.

Continuous drainage function

Should it be necessary to provide continuous drainage, this can be achieved by fitting a 15 mm inner diameter pipe to the drainage hole on the rear of the unit. When installed, water will drain through the pipe and not into the water tank.
Ensure that the drainage pipe runs in a downward direction, and it not bent or damaged in any way so that the water runs freely out of the unit.
When fitting the drainage pipe, make sure that it is pushed into the drainage hole so that it is pushed over the drain outlet which is located about 70 mm inside the unit from the rear cover of the unit.
Refer to the for the location of the drainpipe connection port.

Engineer information

Cabling
Ensure that any cabling is not subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. Also be aware of any effects caused by aging or continual leaks. A halide torch (or any other detector using a naked flame) must not be used.
Detection of flammable refrigerants

DO NOT use any possible sources of ignition to search for refrigerant leaks. A halide torch (or any other detector using a naked flame) must not be used.

Leak detection methods

The following leak detection methods are deemed acceptable for systems containing flammable refrigerants.
Electronic leak detectors can be used to detect flammable refrigerants, but the sensitivity may not be adequate or may need re-calibration (detection equipment shall be calibrated in a refrigerant-free area). Ensure that
the detector is not a potential source of ignition and is suitable for the refrigerant used. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25% maximum) is confirmed.
Leak detection fluids are suitable for use with most refrigerants but the use of detergents containing chlorine must be avoided as the chlorine may react with the refrigerant and corrode the copper pipework.
If a leak is suspected, all naked flames must be removed/extinguished.
If leakage of refrigerant is found that requires brazing, all of the refrigerant gas must be recovered from the system, or isolated (using shut-off valves) in a part of the system both before and during the brazing process.

Removal and evacuation

When breaking into the refrigerant circuit to make repairs- or for any other purpose – conventional procedures shall be used. However, best practice must be followed since flammability is a consideration. The following
procedure shall be adhered to:
Remove refrigerant.
Purge the circuit with inert gas.
Evacuate.
Purge again with inert gas.
Open the circuit by cutting or brazing.
The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be “flushed’ with OFN to render the unit safe. This process may need to be repeated several times. Compressed air or oxygen shall not be used for this task.
Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until the working pressure is achieved, then venting to athe atmosphere, and finally pulling down to a vacuum. This processing shall be repeated until no refrigerant is within the system. When the final OFN charge is used, the system shall be vented down to atmospheric pressure to enable work to take place. This operation is vital if brazing operations on the pipework are to take place. Ensure that the outlet for the vacuum pump is not close to any ignition sources and there is ventilation available.

Charging procedures

In addition to conventional charging procedures, the following requirements shall be followed.
Ensure that contamination of different refrigerants does not occur when using charging equipment.
Hoses or lines shall be as short as possible to minimize the amount of refrigerant contained in them.
Cylinders must be kept upright.
Ensure that the refrigeration system is earthed before charging the system with refrigerant.
Label the system when charging is complete (if not already).
Extreme care must be taken not to overfill the refrigeration system.

Prior to recharging the system is must be pressure tested with OFN. The system must be leak tested on completion of charging but before commissioning. A follow-up leak test must be carried out before leaving the site.

Decommissioning
Before carrying out this procedure, the engineer must be completely familiar with the equipment and all its details. It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample must be taken is case analysis is required before re-use of reclaimed refrigerant. Electrical power must be available before the task is commenced. Become familiar with the equipment and its operation. Isolate system electrically. Before attempting the procedure ensure that: Mechanical handling equipment is available and being used correctly the recovery process is always supervised by a competent person recovery equipment and cylinders conform to the appropriate standards.

a) Pump down the refrigerant system, if possible.
b) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.
c) Make sure that the cylinder is situated on the scales before recovery takes place.
d) Start the recovery machine and operate in accordance with the manufacturer’s instructions.
e) Do not overfill cylinders. (No more than 80% volume liquid charge).
f ) Do not exceed the maximum working pressure of the cylinder, even temporarily.
g) When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the equipment are removed from site promptly and all isolation valves on the equipment are closed off.
h) Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.

Labeling
Equipment shall be labeled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant.

Recovery
When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that all refrigerant into cylinders, and ensure that only appropriate refrigerant recovery cylinders are employed. Ensure that the correct number of cylinders for holding the total system charge are available. All cylinders to be used are designated for the recovered refrigerant and labeled for that refrigerant, i.e. special cylinders for the recovery of refrigerant. Cylinders shall be complete with pressure relief valves and associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs.
The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and shall be suitable for the recovery of flammable refrigerants.
In addition, a set of calibrated weighing scales shall be available and in good working order. Hoses shall be complete with leak-free disconnect couplings and in good condition. Before using the recovery machine, check that it is in satisfactory working order, has been properly maintained and that any associated electrical components are sealed to prevent ignition in the event of a refrigerant release. Consult the anufacturer of in doubt.
The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant Waste Transfer Note arranged. Do not mix refrigerants in recovery units especially not in cylinders.
If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain that flammable refrigerant does not remain within the lubricant. The evacuation process shall be carried out prior to returning the compressor to the suppliers. Only electric heating to the compressor body shall be employed to accelerate this process. When oil is drained form a system, it shall be carried out safely.
