4) Tighten the water tank cap and set the tank back in the water circuit 

compartment. 
* Slide the tank inward until hearing the connection plug catch. 

When the connection plug locks onto the water circuit, the plug's valve 
opens and water runs freely into the circuit. 
Gently try pulling the tank outward. If the tank comes out, it is not 
connected. Set the tank back in the water circuit compartment. 

 

  Note 

 

 

Do not run temperature and humidity operations with the water tank out. Pull 
the tank out only to add to deionized water to it. In this state, water is not 
supplied to the humidifying tray or wick pan, which can prevent temperature 
and humidity from attaining or keeping the set targets. 

 

Do not duplicate setting water tank to water circuit compartment for many 
times. It may create a loss of pressure balance. As the result, siphon effect 
can occur in water tank level sensor tank due to loss of pressure balance, it 
may invite water is drained continuously to outside chamber.

 

 

 

 

CAUTION

 

 

Be sure to close the tank front cover except when the tank is pulled 
out. 

 

It may result in injuries by the front cover when you put your hands into 
the water circuit compartment. 

 

 

To supply water to the humidifying tray 

 

To  supply  water  from  the  water  supply  tank  to  the  humidifying  tray,  it  is 
necessary to run the chamber. The chamber is set to 0°C and humidity control is 
OFF when the chamber is shipped from the factory. 

 

< Procedure > 

1) Turn the circuit breaker ON.(On the right wall of the chamber) 

 

2) Press the

 

POWER switch on the instrumentation. 

 

3) The monitor screen will appear.
