SOME NOTIONS ON HUMIDITY

Air always contains a certain amount of water in the form of vapour. This determines the level of humidity in an atmosphere.
The capacity of the air to hold water vapour increases with temperature.
This is why in our homes, as soon as the temperature decreases, the vapour contained in the air condenses, as is evident on the colder surfaces in the room, such as the windows, walls etc.
The purpose of a dehumidifier is to remove the excess moisture from the air, avoiding the damage caused by condensation.
Experts have established that the optimum environmental conditions for our well being and for the home are obtained between 40% and 60% relative humidity. Lower relative humidity can be achieved with higher room temperatures. For lower room temperatures the achievable relative humidity will be on the higher side, closer to 60%. Therefore, with lower room temperatures, you are recommended to heat the room even minimally.
This considerably increases the dehumidifying power of the appliance.
With heating, the condensation formed by the water vapour on windows and other cold surfaces evaporates into the air to be collected by the dehumidifier.

Failure to observe this warning may result in life threatening injury by electric shock.

Failure to observe this warning may result in injury or damage to the appliance.

Note!
This symbol draws your attention to important recommendations and information.

Problems and repairs

In the event of problems, first try and resolve them by reading the information given in the "Troubleshooting" section. If the appliance requires repair, always contact a Center authorized by the manufacturer. Always insist on original spare parts. Repairs carried out by unauthorized personnel may be dangerous and invalidate the guarantee.

INSTALLATION

Position the appliance in the room to be dehumidified. A free space of at least 2 ft (61 cm) must be left at the front of the dehumidifier, so as not to block the air outlet.
For efficient ventilation a space of about 2-4 in (510 cm) should be left at the back of the appliance. The condensate can be drained in one of the following ways:

Draining into the tank

The condensate can be drained directly into the tank. The tank can be easily removed (fig.1). When the tank is full, remove (fig.1) and empty it into a sink. When finished, replace it properly.

fig.1

NOTE: The tank must be positioned properly for the unit to function.
If you hear the intermittent sound of the beep, it means the tank is not in the proper position.

Continuous external draining

If the appliance is to be operated for long periods but you are unable to empty the tank regularly, you are recommended to use continuous draining.

1. Remove the continuous drain cap 1 by turning it counterclockwise then remove the rubber stopper 2 from the spout (fig. 2).
   
   fig.2
   Note: Some leakages from the spout could happen when removing the rubber stopper 2 (fig. 2).
2. Insert the drain cap 1 in the condensate drain hose (8) till the end (fig. 3)
   
   fig.3
   
   then screw the cap into the spout. (fig. 4).
   
   fig.4
3. Make sure the end of the hose is no higher than the spout (Fig. 3) or water could remain in the tank. Make sure there are no kinks in the hose (Fig. 5).
   
   fig.5

Keep the rubber stopper to close the spout.

Continuous draining using the pump (only on pump models)

The patented heavy-duty pump system allows water removal of up to 13 ft (4m) in height. If you want the water to flow directly to a drain, connect the condensation discharge tube supplied (9) to the connection pipe located on the lower front part of the unit unit (you will first need to remove the stopper labeled PUMP) (fig. 6). Select the dehumidifying function and press the PUMP button.

fig.6

Note: With the condensation discharge hose missing and the pump switched ON, the display will show the symbol PUMP blinking.

To eliminate this problem:

• Check the hose is correctly positioned;
• Disconnect and reconnect the plug.

CONTROL PANEL

* (only on some models)

Description of buttons

1. ON/Standby" button
   ON/Standby" button
2. "Fan" button
   Press this button to select the Fan Speed (MIN or MAX).
3. Thermometer button
   Temporarily displays the temperature measured in the room by the appliance. If you press the button once you will see the room temperature in F for a few seconds, then in C for a few seconds, then the display will return to the current level of humidity in the room. If you press the button multiple times, it will cycle through these displays faster. Note: Temperatures displayed are indicative only.
4. Humidity increase/decrease buttons
   These buttons are used to adjust the desired humidity level, with 5% increments; they are also used to set the timer. From 0 -10 the hours increase by 30 min. and from 10-24 the hours increase by 1 hour increments.
5. Pump button (only in some models)
   When you press the "Pump button" the display will show "PUMP/POMPE". If the display shows "PUMP/POMPE" blinking, it means that the pump is not operating correctly.
6. Timer button

CLEANING AND MAINTENANCE

Always unplug the appliance from the power outlet before performing any cleaning or maintenance operations.
For safety reasons, never wash the dehumidifier using a jet of water.

Cleaning the cabinet

• Clean the appliance using a damp cloth then dry with a dry cloth.
• Do not use petrol, alcohol or solvents to clean the appliance.
• Do not spray liquid insecticide or similar products as they may deform the plastic.

Cleaning the air filter or silver-ion air filter

If the filter is dirty, air circulation is compromised and the efficiency of the dehumidifying and air purifying functions decreases.
It is therefore good practice to clean the filter at regular intervals. The frequency depends on the duration and conditions of operation.
If the unit is used constantly or systematically, you are recommended to clean the filter once a week.

To remove the filter, pull it down as shown in figure 7.

fig.7

Use a vacuum cleaner to remove dust accumulations from the filter. If the filter is very dirty, rinse well with lukewarm water. The temperature of the water should not exceed 40˚C. After washing the filter, allow it to dry completely before reinserting it.
If present, the silver-ion air filter, besides retaining powder particles, has also an efficient antibacterial action. In addition, it greatly reduces irritants such as pollen and spores.
The filter is treated with small particles of silver (on the scale of millionths of a millimetre) which are able to block the multiplication of and destroy any bacteria or spores coming into contact with them.

If the appliance is not used for long periods

• After unplugging the appliance from the power outlet, empty the tank.
• Clean and reposition the filter.
• Cover the appliance with a plastic bag to protect it from dust.
