● Never use household detergents or diluents, volatile
oils, alcohol or abrasive powder for cleaning.
● Do not spray water on the main unit and AC adapter
(it may cause electric shock or malfunction)
Cleaning and maintenance
Routine cleaning and maintenance (when the main
unit is dirty)
If the main unit is dirty, wring a soft cloth soaked in
warm water or neutral detergent (except citrus type)
and wipe it gently, then dry the surface gently with a
dry cloth. (Do not rub the resin part hard, or else it
may cause damage)
Routine cleaning and maintenance
Please clean the dust from the front guard, air supply
opening, rear guard and suction port with a vacuum
cleaner.
Internal cleaning and maintenance
Remove the front guard and the fan blade as described
below and perform internal cleaning and maintenance.
Remove parts
①It is difficult to remove the front guard in the current
state. Therefore, adjust the fan to slightly tilt (that is,
the swing state as shown below). First remove the
fixing screw on front and rear guards, then turn the
front guard to the left (counter-clockwise) and
remove it.
②Rotate the spinner fixing the blade to the right and
remove it, and then remove the blade.

Storage method
Fold the support frame to minimize volume (see page
12) before storage.
Clean the dust from the front guard, air supply
opening, rear guard and suction port with a vacuum
cleaner.
●Fully dry after cleaning and maintenance.
●Put on a plastic bag, put it in the packaging box, and
store it in a place where there is no moisture.
●When storing for a long time, remove the battery of
the remote control.

Folding and minimizing the support frame
The unit can be folded (minimized) in a compact state
when it is not in use.
1. Stop the operation with the fan blades facing the front,
unplug the AC adapter from the power socket, and
remove the DC plug from the main unit.
2. Slowly lower the main unit toward the support frame to
overlap the main unit with the support frame.
3. Pull the fixing strap up and out ①, then wind it forward
② and attach it to the hook ③.
Do not place the minimized fan upright in a
place where people are passing through.
It is possible to fall down and cause accidents.
Please insert the remote control into the storage
area and store the AC adapter in an appropriate
place.
Fixed strap winding method
Always unplug the AC adapter from the
power socket before folding.
● When folding the support frame, be
careful to avoid pinching your fingers.
It may cause injury or malfunction.
● Do not leave the minimized fan standing
upright for a long time. Do not store it
within the reach of children. It is possible
to fall down and cause accidents. When
saving for a long period of time, put it
down, or place it in a place where it will
not fall down (such as a gap).
