tap water in a hardwater area we recommend regular cleaning to avoid
limescale build-up. Make sure water temperature does not exceed 40°C.

(Put the appliance down on a suitable flat horizontal surface, and where it is to be
used.)

Note: Do not use on any surface that may be damaged by water, (during refill
some water drops may be spilt)

Note: If the indicator light is Red, water is still filling the water reservoir (in
the base unit), wait until it turns Blue, the unit will start working.

Warning: Whenever a filled water tank is fitted to the top of the white base,
water will flow into the water reservoir below, filling it to the brim with water,
make sure not to spill by lifting and tilting it!

In use:
Turn control knob (4) to set the vapor release rate depending on requirement,

including dryness or size of room.

When the tank is short of water, the indicator will turn Red once again, and vapor
release will stop. Turn off and un-plug the unit from the wall socket.

How to re-fill with water:

1. Remove the white mist cover from the top of the blue water tank. Never remove

or fill the water tank with the mist cover attached.
