LOW HUMIDITY MODE
The humidity in the chamber goes up over 90 %R.H. if the unit is running without low humidity mode
when moisturized material is put inside the chamber. This may result in the condensation on the inside
of the door or clearance in the chamber.
The low humidity mode is a running mode to reduce the condensation under above condition by running
control with the set temperature between 20
o
C and 40
o
C.
Refer to page 40 for the setting of low humidity mode.
*Default setting of the low humidity mode is 0 (Not available).
[When selecting the low humidity mode]
The compressor is on/off more frequently than normal to reduce the condensation in the chamber.
Accordingly, the fluctuation of the chamber humidity is more than the normal running mode.
The chamber humidity varies between about 80 %R.H. and 50 %R.H. when the chamber temperature is
set to 37
o
C and the ambient temperature is 20
o
C.
CAUTION
The material in the chamber may be dried depending on the usage condition when the low humidity mode
is selected. Do not select the low humidity mode when the drying of culture media should be avoided.
[When selecting the normal mode (no low humidity mode)]
Pay attention to the followings when the chamber temperature setting is higher than the ambient
temperature with moisturized material put inside the chamber.
·
The condensation may be found on the inside of the door or clearance in the chamber. Wipe off the
condensation with a dry cloth.
·
Because of the structure that dew saucer at door bottom receives chamber condensation, water may
gathered in the saucer. Wipe off the water with a dry cloth.
·
The condensation is held on the dew saucer and drained into the evaporating tray. The evaporating
pipe is not heated when the compressor is off. Therefore, it is needed to clean the evaporating tray once
a week.
*The amount of condensation depends on the usage condition.
CAUTION
Clean the evaporating tray regularly when selecting the normal mode (no low humidity mode). Spilled
water from the evaporating tray causes the mold.
