CUOGHI WMD 50 Air Dehumidifier Instruction Manual

CUOGHI WMD 50 Air Dehumidifier

Technical specifications

Operating principle

• The appliance uses a fan (5) to suck up the air (14) to be dehu-midified and pass it through the refrigerator circuit evaporator (9).
• In this way the temperature of the air is lowered to below its dew point and the vapour condenses to form drops of water that are collected in the appropriate tank (11).
• The condensate water is NOT drinkable. Do NOT drink this water anyway.
• The air thus dehumidified is passed through the condenser (10) that raises its temperature slightly higher than the initial value. In this way the quantity of humidity contained in the environmen-tal air is gradually decreased until it reaches the desired value.
• When the dehumidifier works in a room it reduces the humidity of the walls and floor of the room, as well as in the materials contained therein.

The defrosting cycle

• If the temperature goes below 16°C ice may form on the evapo-rator (9). The ice must be regularly melted to prevent it from reducing the air passage. The electronic board automatically performs the defrosting cycle (see ahead). During the defrosting cycle the compressor (6) stops. The time it takes to melt the ice changes with the humidity and temperature.

Installation

• For correct installation, follow the series of operations described below.

Handling

• Before installation it is advisable to bring the packed dehumidi-fier as close as possible to the place where it will be mounted.
• CAUTION: The size and the weight of the machine require the aid of means such as pallet trucks and trolleys for handling. NEVER lift the machine alone.

Placement

Wall installation

• Use the bracket as a template to mark the holes on the wall as shown in Pic.3.
• Make sure that the wall is able to support the device in operating conditions.
• Drill on the wall n.3 holes Ø10mm, 65mm deep as shown in Pic.3. Alternatively, you can apply smaller screws (not sup-plied) using the four Ø5 holes.
• Clean the inside of the holes.
• Insert the three supplied expansion plugs holding in vertical position the expansion tabs.
• Secure the bracket using the three screws supplied.
• To respect the minimum distance of 0,5 meters from the bottom (Pic.2) drill the holes to at least 0.8 meters from the floor.
• Lift the machine and hook the rear bracket S to M bracket mounted on the wall.
• Rotate the two legs T, which are located on the rear-bottom side of the frame, to make vertical the position of the dehu-midifier.
• Make sure the dehumidifier fits completely on the rear brack-et M.

Safety locking

• Install the safety bracket R in the bottom side of the dehumidi-fier. The bracket must be fixed to the wall and the structure of the dehumidifier with the screws.
• Do not operate the dehumidifier without the safety bracket. The safety bracket must be firmly screwed to the dehumidifier and the wall.
• The absence of the safety bracket may cause an ac-cidental fall of the machine and cause damage, even serious, to persons and property.

The exhaust pipe

• For the drain connect a 14mm internal diameter rubber hose to the connection D on the lower-left side of the frame.
• To ensure proper drainage of water make sure that the drain hose is sloped and well laid out, with no elbows or narrowing of any kind.

The control panel

• S1 – Green light ON The green light indicates when the dehu-midifier is operative, otherwise it blinks on status 0 (powered but off).
• S2 – Red light, full tank The light blinks, together with the green one S1, when the tank is full, missing or incorrectly positioned.
• S3 – Yellow light, defrost The light switches on during the auto-matic defrosting cycle.
• T1 – Decrease button Pushing this button will decrease the val-ue of the display D down to 0.
• T2 – Increase button Pushing this button will increase the value of the display D up to C.
• D – Display The display shows the working state of the dehu-midifier according to the table below (Tab.B). The value 0 means OFF, from 1 to 9 means automatic functioning and is controlled by the humidistat that switches the dehumidifier on or off if the value of the relative humidity is higher or lower than the one shown in Tab.B. The value C means ALWAYS ON and the dehu-midifier works independently from the humidity value: never-theless, any alarm has priority over the functioning mode.

Failures
The display is used by the electronic device to show particular situations (Tab.C) If an error message is displayed please contact your dealer for repair.

How to use

Start-up

• When the plug is connected the display D blinks for 5 seconds and shows the last functioning mode selected: then, if the func-tioning mode is different to zero, the display stops blinking.

Shutdown

• To switch off the dehumidifier push button T1 until the value displayed is 0. When zero is selected both the green light S1 and the display D blink.

The defrosting cycle

• The electronic board automatically performs the defrosting cycle to melt the ice and keep the air flow efficient even at lower tem-peratures. The yellow light S3 switches on when the defrosting cycle is started.

Maintenance

• The dehumidifiers of the WMD series need no particular main-tenance. It is advisable to dust them and keep the air intake and outlet grids clean. Contact your dealer if it should function badly or break down. In the event of damages the cable must be re-placed with a similar one only by experienced and qualified staff.
• ATTENTION: Before doing anything on the appli-ance disconnect the power supply by unplugging the machine.

How to clean the filter

• The filter can be cleaned with a vacuum cleaner or with water: in this case dry it before assembly.
• Keep the air filter clean, especially in dusty rooms: a dirty filter reduces the air flow and efficiency of the dehumidifier.

How to remove the air filter

• Remove the front grid G, then remove the air filter F.

How to put the air filter on

• Place the air filter F on the inlet grid, then mount the front grid G.

Storage

• Keep the appliance in a room with a temperature between – 25°C and +55°C.
• When the appliance is still packed follow the instructions on the box.
• Do not place other heavy material on the box.

Checks to carry out before and after a long period of inactivity Before

• Disconnect the plug.
• Cover the machine to protect it from dust.

After

• The fan must turn freely without gripping;
• Start the machine following this manual’s instructions.

Disposal of the product

• The crossed-out wheelie bin symbol indicates that the product must be collected separately from other waste at the end of its useful life.
• The user must therefore take the appliance at the end of its useful life to a special centre for electrical and electronic waste collec-tion or hand it back to the retailer upon purchase of a new prod-uct of an equivalent type, on a one-for-one basis.
• Proper segregated waste collection of old appliances for subse-quent recycling, treatment and environmentally compatible dis-posal helps avoid possible negative effects on the environment and health and favours recycling of the materials the product is made of.
