Thank you for choosing this dehumidifier. To get the very best out of your dehumidifier it is advisable to read these instructions before using the appliance. By doing so you will obtain optimum results and maximum safety.

Electrical connections
Before plugging the appliance into the power socket, check that:

• The mains power supply corresponds to the power supply indicated on the rating plate.
• The power socket and electrical circuit are adequate for the appliance.
• The power socket matches the plug. If this is not the case, have the plug replaced by a qualified electrician;
• The power socket must be adequately earthed; Failure to respect this safety rule absolves the manufacturer from all liability. This appliance is manufactured in compliance with EEC standard EN 55014 on the suppression of radio interference.
• The cable must be replaced by approved service personnel only.

Installation

Positioning

Position your dehumidifier wherever your condensation or damp problem is. A clear area of at least 50cm must be left at the front and back of the dehumidifier to ensure adequate ventilation. Do not place the dehumidifier next to a radiator or other heat source as this will reduce its performance.

For ongoing usage we suggest positioning in a hallway or on a landing.

Please remember to keep internal doors ajar to allow air circulation. Before using your dehumidifier for the first time, it should be stood upright for 24hrs prior to use. When moving it from room to room it is advisable to wait an hour before using it again.

Water Collection

The water collected (condensate) can be drained in one of two ways:

1. Draining into the tank
   The condensate can be drained directly into the tank located inside the appliance (fig. 1).
   
   The tank can be easily removed by pulling firmly on the two sides of the tank. It also has a handle making it simple to carry and empty.
2. Continuous external draining
   If the appliance is to be operated for long periods of time but you are unable to empty the tank, you are recommended to use the continuous drain facility.

• Drill the inside of the drain spout using a small drill bit. (Fig. 2).
  
• Fasten the rubber hose to the spout. For models without drain hoses supplied, we suggest you purchase a rubber hose around 2m long, with an internal diameter of 9.5 mm.
• Make sure that the hose is not higher than the spout (Fig.3),otherwise water will remain in the tank; also check that the hose is not twisted.
  

N.B: Keep the rubber bung. You will need it to plug the hose or close the spout if you revert to draining into the tank (see point A).

Controls

Tank control system

This dehumidifier is fitted with a special device to ensure correct operation.

A red indicator light on the control panel comes on to warn the user when:

1. the tank is full → empty the tank
2. the tank is missing → replace the tank
3. the tank is in the wrong position → position the tank correctly
4. in continuous drain: the hose is obstructed or placed too high above the drain spout →remove the obstruction.

Once the cause has been eliminated, the light goes out and the appliance resumes operation.

Dehumidification light (DEC16)

This switches on when the machine is dehumidifying. The light remains on only when the appliance is effectively dehumidifying; if the humidity in the room is already low enough, the light will be off.

Dehumidification standby/low temperature operation light

The light comes on in the following two cases:

1. To signal a delay of around 3 minutes in the start-up of the appliance. This is due to a safety device which protects the compressor.
2. To signal low temperature operation. When the room temperature is too low, the electronic low temperature operation device is activated. This device allows the appliance to operate by alternating dehumidification cycles and fan only cycles. This is to avoid the formation of ice. For frequent use in cold environments, it is recommended to heat the room at the same time. This allows the dehumidifier to operate in conditions that ensure better performance and faster dehumidification.

How to dehumidify

How to dehumidify (DEC12 with humidistat only)

1. Plug the appliance into a mains socket.
2. Check that the "tank full/tank missing" light is off; if not, place the tank in the correct position.
3. The humidistat knob is used to adjust the humidity level as desired (MIN/MED/MAX)
   To easily select the right humidity level, we suggest you operate as follows: Turn the humidistat clockwise as far as it will go to the MAX position. (The dehumidification standby light comes on for the first 3 minutes after which the appliance starts dehumidifying). Leave the unit on this setting until signs of excess moisture (e.g. condensation on windows) decrease. This can take several weeks. At this point slowly turn the humidistat knob anti-clockwise until the appliance switches off. The dehumidifier will then keep the humidity at the selected level automatically.

Selecting operating functions (DEC16 only)

Functions

Your appliance features 4 functions: air purification , low consumption dehumidification , comfort function , and maximum/clothes drying .

Turn the function knob to select the functions, as required.

Purification function

This function circulates the air through the high-efficiency electrostatic filter, purifying it without dehumidifying.

The filter is also active in all dehumidifying functions.

Low consumption dehumidification function

The appliance dehumidifies with maximum economy and at the lowest noise level (using the lowest fan speed). On reaching the required humidity level the appliance switches off

Comfort function

By using this function you can reach the desired comfort level of humidity faster. The appliance uses the higher fan speed.

Dry function (clothes drying)

For initial use and when required to work in very damp areas (e.g. for drying clothes), the dehumidifier works continuously (independent of the humidistat).

Maintenance

Always remove the plug from the power socket before performing any cleaning or maintenance operations. For safety reasons, never wash the dehumidifier using a water jet.

Cleaning the cabinet

• Clean the appliance using a damp cloth then dry with a dry cloth.
• Never use petrol, alcohol or solvents to clean the appliance.
• Never spray the appliance with insecticides or similar. These could cause the paint to flake or plastic parts to warp.

Cleaning the permanent air filter

Your dehumidifier is fitted with a permanent 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 on a regular basis, you are recommended to clean the filter once a week.

• Remove the air filter, by pulling it as shown in fig. 4.
  
  fig. 4
• Use a vacuum cleaner to remove dust accumulations from the filter. If the filter is very dirty, wash in warm water and rinse several times. The temperature of the water should not exceed 40˚C.After washing the filter, allow to dry completely before replacing it.

Electrostatic purification filters (DEC 16)

In addition to the permanent filter a second high-efficiency elec- fig, 4 trostatic filter which can capture very small particles (down to 0.3 µm) is found on the permanent filter housing. The filter is active in all of the functions.

The filter should be replaced regularly (depending on usage)

If the appliance is not used for long periods

• Unplug from the mains socket and empty the tank.
• Clean and reposition the filter.
• Cover the appliance so that dust does not build up.

Technical Characteristics

Brief note on humidity

Air always contains a certain amount of water in the form of water vapour.

This amount of moisture is commonly known as the humidity.

The capacity of the air to hold water vapour increases with the 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, to control condensation within the home. Experts have established that the optimum environmental conditions for our well being and to preserve objects are obtained between 40% and 60% relative humidity. Below these levels the air can feel too dry and may cause skin complaints and even static electric shocks.

If temperatures in the home are lower than 10°C for prolonged periods low level heating will be necessary to allow the condensate to evaporate into the air before dehumidification can take place. The air will however be slightly warmed by the dehumidifier as the dry air leaving the dehumidifier is about 1°C higher than normal room temperature.

Electrical requirements

Before using this appliance ensure that the voltage indicated on the product corresponds with the main voltage in your home, if you are in any doubt about your supply contact your local electricity company.

The flexible mains lead is supplied connected to a B.S. 1363 fused plug having a fuse of 13 amp capacity. Should this plug not fit the socket outlets in your home, it should be cut off and replaced with a suitable plug, following the procedure outlined below.

Note: Such a plug cannot be used for any other appliance and should therefore be properly disposed of and not left where children might find it and plug it into a supply socket - with the obvious consequent danger.

N.B.We recommend the use of good quality plugs and wall sockets that can be switched off when the machine is not in use.

the wires in the mains lead fitted to this appliance are coloured in accordance with the following code:

GREEN AND YELLOW EARTH
BLUE NEUTRAL
BROWN LIVE

As the colours of the wires in the mains lead of this appliance may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows:
The wire which is coloured green and yellow must be connected to the terminal in the plug which is marked with the letter E or by the earth symbol or coloured green or green and yellow.

The wire which is coloured blue must be connected to the terminal which is marked with the letter N or coloured black.

The wire which is coloured brown must be connected to the terminal which is marked with the letter L or coloured red.

When wiring the plug, ensure that all strands of wire are securely retained in each terminal. Do not forget to tighten the mains lead clamp on the plug. If your electricity supply point has only two pin socket outlets, or if you are in doubt, consult a qualified electrician.

Should the mains lead ever require replacement, it is essential that this operation be carried out by a qualified electrician and should only be replaced with a flexible cord of the same size.

After replacement of a fuse in the plug, the fuse cover must be refitted. If the fuse cover is lost, the plug must not be used until a replacement cover is obtained. The colour of the correct replacement fuse cover is that of the coloured insert in the base of the fuse recess or elsewhere on the plug. Always state this colour when ordering a replacement fuse cover.

Only 13amp replacement fuses which are asta approved to B.S. 1362 should be fitted.

This appliance conforms to the Norms EN 55014 regarding the suppression of radio interference.
