5. Attaching wet-bulb wick
Caution
Change the wet bulb wick regularly.
When the wet bulb wick is deteriorated
(discolored), replace it with new one. The life
of the wick differs depending on the operating
temperature, humidity, and water quality.
However, replace the wick at least once in a
month. If you use the same wick for a long
time, its performance is worsened, and normal
humidity control cannot be provided. Also, it
will cause water leak because of saturation
state and cause a crash of humidity control
parts.

You can check the wet-bulb wick for dryness
by the following way.
Attach the wet bulb wick and turn on
[Manual Drain] key. When the humidifying
operation is active even while the operating
temperature is within not-humidified range
(5
℃
or lower set temperature), the wet-bulb
wick is dry.
You must wet the wet-bulb wick with
purified water enough before operation.
If once the wet-bulb wick is dried completely,
sometimes it cannot include any moisture. In
such a case, replace the wet-bulb wick with
new one.
*
Dry and wet bulb method is adopted to measure
the humidity. Cover the temperature sensor for
wet-bulb with the wet-bulb wick surely by
following the below procedures.
・
Wet-bulb wicks are supplied 5 pieces singly
with aluminum package. Clean your hands
with some soap before opening the package
not to get the wick dirty.
・
Wet the wet-bulb wick with purified water,
and put the temperature sensor for wet-bulb
into it.
The wet-bulb wick must be capped on the
temperature sensor for wet-bulb.
If you cap it on the temperature sensor for
dry-bulb by mistake and the operation is
started, the temperature and humidity cannot
be measured properly, and may cause some
troubles.
You must wet the wet-bulb wick with
purified water enough before operation.
If it is not sufficient, refill some purified
water by a supplied dropper.
Remove the wet-bulb wick in advance, when
only the temperature is controlled without
humidity control or when operating at 5
℃
or
less.
If you reposit the wet-bulb wick after
opening, keep it dry and put it into the
aluminum bag, and zip it.
The aluminum bag blocks oxygen and
moisture vapor .

Operation without humidity control
Turn on [Manual Drain] switch.
Water is not supplied into the
humidification tray and the wick holder.
Set the humidity [0%RH] and start the
operation.
The humidity control does not become
active even if water is supplied into the
humidification tray and the wick holder.
When the setting temperature is less than
5
℃
, water is drained automatically from
the humidification tray and the wick
holder.
Do not refer the humidity indication when
the wick holder does not have any
humidifying water.
