be over 40° C. (cold boiled water or demineralised water are recommended).

1.Remove the water tanks out from the base.

2.Unscrew the water outlet valve (L).

3.Fill the tanks with clean water and screw the valve back tightly onto the tanks. (See Fig. 4)

4.Put the water tanks back on the base. (see Fig.4).

Switch the Unit On and Off (See Fig. 1 F1)

1.Put the plug into the main supply.

2.Press Power ( ) (F1) to switch on and off the Ultrasonic Humidifier. The LED screen is lightened when the power is on.

NOTE: This unit has a memory. The control panel will remember the previous mist output level setting after the unit has been turned off. However, if the unit is unplugged, the control panel will reset to Hi (II) and will no longer remember the previous mist output level setting.

Mist Control/ Humidity Level Control (See Fig. 1 F2)

To raise or lower the humidity level, adjust the fan to low or high mist output levels:

I / Lo	=	Low mist output
II / HI	=	High mist output

NOTE: Mist output level setting alternates Hi(II) to Lo(I) with one touch to the Mist Control (F2) on the Control Panel (F).

Control Panel

The control panel has a humidity indicator light and will show differing colours as follows:

Amber	=	Low humidity. (Below 50%
		Relative Humidity Level)
Green	= Comfort Humidity Level (About
		50% Relative Humidity Level)
Blue	=	High humidity. (Above 50%
		Relative Humidity Level)
Screen flickers	= water level in basin is low,
		refill tanks

NOTE: The recommended humidity level is between 40% - 50%.

AUTO SAFETY SHUT OFF

This Ultrasonic Humidifier has two built in safety devices:

1.When the water level in the basin is low, the transducer will automatically shut off. Refill the tanks as instructed in "Operating Instructions" to operate the humidifier again.

2.When the Mist Channel is not positioned correctly on the base, the fan and Transducer will automatically shut off and the Control Panel screen will flicker. Remove and replace the Mist Channel to ensure proper fit.

FILTER USE

The Water filters are used to retain minerals in

your water and to provide clean moisture. The filter life is determined by the average daily use of your humidifier and the water hardness in your area. The harder the water, the greater the amount of minerals in the water and more often you will need to replace the filter. It is strongly recommended that each filter is replaced every 2 months, (depending on use), or when white dust is emitted from the unit.

1.Make sure the unit is turned off and disconnect from the mains outlet. Remove Water Tanks (M) and Mist Channel (B).

2.If replacing, remove the Filters (O) from the base and dispose.

3.Remove the protective plastic bag from the new filters. Soak filters thoroughly by immersing filters in water for 5 minutes. Install the filters into the base.

4.Fill the water tanks with clean, cool tap water and replace it in the base. Wait 15 minutes for water to pass through the filters before turning on the unit. The 15 minute wait is necessary to ensure that the filters are properly saturated and the water is at its optimal level for best performance.

CARE AND CLEANING

Humidifiers provide comfort by adding moisture to dry, heated indoor air. To get the most benefit from the humidifier and to avoid product misuse, follow all instructions carefully, specifically the operation, care and maintenance guidelines. Please note this is an electrical appliance and requires attention when in use.

Cleaning your humidifier every one or two weeks, depending on the water conditions is important in order to maintain efficient, healthy, odour-free operation. Water quality varies widely and, combined with build-up of mineral scale in your humidifier, may under certain conditions promote the growth of micro-organisms in the water tank.

Before cleaning, Please note the following:

•DO NOT use soap, detergents, abrasives, gasoline, glass or furniture polish, or boiling water to clean any part of your Ultrasonic Humidifier. These will interfere with the proper operation of your unit and may affect its appearance.

•DO NOT use sharp or metal objects to clean mineral deposits in the reservoir. Contact with sharp objects can result in damage to the plastic.

•Mineral deposits should be soaked for up to 20 minutes in plain vinegar and water to help with their removal.

•DO NOT clean any part of your humidifier in the dishwasher.

Daily maintenance:

1.Before cleaning, switch off the unit and unplug the unit from the electrical outlet.
