Connected dehumidifier 50L/d ROHAN

The operation of a compressor dehumidifier is similar to that of a refrigerator. In fact, the condenser (the very fine lamella grid) is slightly colder than the ambient air. Thus, the water contained in the air condenses and flows into the tank. Below about ten degrees, these water droplets risk freezing instantly on contact with the condenser, and forming a block of ice at the back of the device. To avoid this, new generation dehumidifiers are equipped with a "defrost" or "anti-freeze" mode that will disconnect the compressor for a while (or longer if it is very cold). The air thus circulates at room temperature and the device does not freeze, but it is almost ineffective.

Your dehumidifier is equipped with a lift pump. If you have not connected the small specific hose to the pump and turned on the indicator light on the control panel, then it will leak and prevent the tank from filling. You must therefore deactivate the PUMP indicator light. If this is already the case, check, by blowing into it, that your hose is not obstructed.

Continuous drainage means that you don't have to empty the tank all the time. Thus, the condensates (water collected by the dehumidifier) ​​flow away by gravity. This operation is always carried out using a short pipe (maximum 50 cm) with an internal section of approximately 1 cm.

It is not impossible but not recommended because if your pipe gets clogged or does not drain well, the water will rise up in the pipe and flooding is guaranteed. If you risk it, oversize the diameter of the extension pipe and join the 2 pipes well, for a good seal. Make a small hole on the upper part of the pipe, directly after the water outlet, at the back of the appliance.

Swing mode is the motorization of the air outlet flap. It ensures better ventilation in the room and better circulation of dried air. This air mixing mode is recommended in particular for use with a tumble dryer.

First, we recommend removing the tank to make installation easier. Then, connect the hose to the unit through the opening on the back or side of the dehumidifier. Replace the tank and place the other end of the drain hose directly into a water drain.

Yes, your device is delivered complete and ready to use.

The ROHAN dehumidifier works with R290 gas, as required by the European Union from 2021, for all devices containing a refrigerant gas.

As specified in the user manual, when you program your device to reach a certain humidity level and this level is reached, the compressor stops and only the fan continues to operate.

This is completely normal and complies with a European safety standard (EN 60335-2-40 concerning "Household electrical appliances and analogues - Safety - Part 2-40: Special requirements for electric heat pumps, air conditioners and dehumidifiers").

If you want your appliance to turn off completely, you can turn it off manually or via the smartphone app, or set a timer.

ERROR E1/H1: this is either an operating error of the temperature or humidity sensor, or the device is operating in an abnormal environment (near a radiator for example). If the product is dirty: clean the back of the device with a vacuum cleaner.
ERROR E2: room temperature problem (too hot or cold). If the product has just been unpacked, leave it in the open air for 48 hours.
ERROR P1: the device is in Defrost mode, this is normal.

It depends on the production date of your device. Old version: plug the device for 10 seconds, unplug it for 20 seconds, 3 times in a row. Recent version: press the start button while plugging in the power plug at the same time.

The inner diameter of the pipe is 5 mm and the outer diameter is 8 mm.

This alert corresponds to the humidity sensor, located at the back of the device (the small square to the right of the rear grille). Indeed, after a few months of use, the sensor collects dust and this becomes loaded with humidity, which distorts the device's measurements. To remedy this, we advise you to take the device out of the room in which it is located so that the dust present on the sensor dries, and to give it a good blast with a hair dryer to remove it.

You've noticed a brownish liquid flowing from the hose or present in the tank of your dehumidifier? This phenomenon can be surprising, as the water extracted from the air is supposed to be clear. Rest assured: no internal part of your appliance produces this type of liquid. It is most likely pollution present in the ambient air, especially if the appliance is used in a garage or a poorly ventilated space.

Hypothesis No. 1: Presence of Fungal Spores or Mold

In humid environments like garages, microscopic spores (mold, fungi, etc.) can float in the air. Once captured by the airflow of the dehumidifier, they are carried with the condensed water and can color the liquid brown. You might also perceive a musty or damp earth odor when approaching the reservoir.

Hypothesis No. 2: Air Pollution by Organic Residues or Greasy Dust

A garage is often an environment exposed to oils, fuels, solvents, brake dust, etc. These particles, suspended in the air, can be sucked in and mix with the condensed water, giving it a dark brown tint. This phenomenon is common in rooms where volatile organic or chemical substances circulate.

What to do if this happens?

Here are some recommendations to clean your appliance and identify the exact origin of the problem:

1. Clean the drain hose with hot water and a little white vinegar. Soaking in a mild disinfectant solution can also be helpful.
2. Rinse the collection tank and the drain outlet thoroughly.
3. Spray a mixture of warm water and white vinegar (20%) directly onto the fins at the back of the appliance to eliminate any biological traces.
4. Let the dehumidifier run for 24 to 48 hours under the same conditions.
5. If the brown liquid reappears:

• It is then highly likely that the ambient air is the cause of this discoloration. You can:
• Install a pre-filter on the air intake (a fine foam or a coffee filter can work temporarily),
• Test the appliance in another room to see if the phenomenon disappears elsewhere.
