Dehumidifier

This is a model w ithout a Peltier compressor. A Peltier dehumidifier consumes little but is of low power. Its maximum dehumidification is 750mL/day with a humidity of 90% and a temperature of 28/30°C. If the room temperature is lower than 20°C, the device loses capacity. It is suitable for small spaces and small humidity problems. It will wonderfully replace Rubson type absorption cartridges.

You have 3 methods to evacuate the condensates (the recovered water):

• Empty the tank once full (ORAIN stops automatically).
• Continuous drainage: the included drainage pipe allows you to connect ORAIN to a waste water drain on the ground. The short pipe must follow a slope so that the water flows by gravity.
• Lifting pump (not included): install this accessory in the tank to raise the water to a certain level or to evacuate it over a longer distance.

• Make sure the unit is not placed against a wall or that a piece of furniture is not blocking the air inlet of the dehumidifier. If so, move it.
• The desired humidity level is not set low enough: switch to "Continuous" mode instead of "Auto".
• The room temperature is below 15¬∞C: this is the limit at which most compressor dehumidifiers are ineffective.

The regulation of dehumidifiers has changed on 01/01/2020. Your dehumidifier now works with R290 gas, as required by the European Union from 2021, for all devices containing a refrigerant gas. Depending on the quantity of gas contained in the device, the fan must either remain on when the compressor turns off, or restart from time to time (duration varies depending on the manufacturer) to re-measure the humidity level. This is completely normal and complies with a European safety standard (EN 60335-2-40 concerning "Household and similar electrical appliances - Safety - Part 2-40: Particular requirements for electric heat pumps, air conditioners and dehumidifiers").

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.

Below about fifteen degrees, a compressor or Peltier dehumidifier loses much of its efficiency. The reason is simple: to create condensation, the compressor's role is to cool the condenser. If the air is too cold, the drops formed on the condenser will freeze. On older products, you can see blocks of ice forming. Today, there are "Defrost" modes that disconnect the compressor, but the device no longer dehumidifies. It is therefore advisable to opt for a desiccant or low-temperature dehumidifier that works with a large silica wheel. Its efficiency will be almost constant at 0°C or à 20°C.

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.
