AUTO WATER SUPPLY SYSTEM
Auto water supply system (MCO-80AS) is
available as an optional accessory.
This system kit supplies water from its tank
automatically when the water level alarm lamp
(RH PAN) blinks due to decrease the water in the
water reservoir.
For starting to use auto water supply system, it is necessary to set F26
:
001 or 002 (refer to page 21),
and F27 :001. Following procedure is the setting of F27.
Description of operation
Key operated
Indication after operation
1
-----
The current chamber temperature
is displayed.
2
Press calibration key for 5
seconds.
The third digit on the digital
temperature display is flashed.
3
Set the figure to F27
with the digit shift key
and numerical value shift key.
When pressed, the settable digit is shifted.
When pressed, the figure of
settable digit changes.
4 Press enter key.
ENT
The current set value is displayed
on the digital CO
2
density indicator.
The first digit is flashed.
5 Set the figure to 001 with the
numerical value shift key.
When pressed, the figure of
the first digit changes.
6 Press enter key.
ENT
Set value is memorized.
The current chamber temperature
is displayed.
●
When the water in the water reservoir decreases less than approximately 5 L, water is supplied little by
little to prevent the water temperature from dropping rapidly. (The water supply valve is opened and
closed repeatedly.)
●
Automatic water supply stops its operation while the outer door is open.
●
If the water supply tank becomes empty or the connection to the incubator is released, the automatic
water supply operation is finished and doesn’t restart automatically. Water level alarm lamp
（
RH PAN
）
will remain blinking though the buzzer is not activated.
To restart the automatic water supply, refill the tank (Capacity:20 L) and do either (1) or (2) below.
(1) If you want to minimize the impact on the chamber temperature.
Press alarm buzzer stop key (BUZZER). By pressing this key, the automatic water supply will start
operating again. In this case, water is supplied little by little to minimize the change of the chamber
temperature.
(2) If you want to refill the water reservoir in a short time.
Turn off the power switch once and turn on again.
The water reservoir is refilled rapidly by automatically keeping the water supply valve open for 2
minutes after the 2 minutes water level checking has been finished. In this case, water supply is
completed in a short time but the chamber temperature will be temporarily dropped.
