Checking water level in the humidifying tray 

Water is supplied from the water tank to both the humidifying tray and wick pan. 
To ensure proper operation, check water in the humidifying tray and wick pan is 4 
mm lower than the test area floor. 

 

< Procedure > 

1) Check that the humidifying heater is completely under water and that water 

is not overflowing from the humidifying tray. An inappropriate water level will 
destabilize temperature and humidity control. 

2) Check water does not overflow the wick pan.

 

   

  Reference 

 

If water in the humidifying tray water level regulator is above or below the WATER 
LEVEL mark (water is overflowing or the humidifying heater is sticking out of the 
water in the humidifying tray), the following may have happened. 
•The water tank is not properly connected to the water circuit compartment. 
•The chamber is not installed on a flat, level floor. 
•Water in the humidifying tray water level regulator is not being regulated to the 
correct level. 
In this case, regulate water level as explained here following. 

 
 

Checking water level in the small humidifying tray water level regulator (SH only) 

Check the water level in the regulator is at the WATER LEVEL mark. 
 

 

CAUTION

 

 

Before  taking  off  the  humidifying  tray  water  level  regulator  level 
check panel, shut OFF power at the main power switch. 

 

It may result in injuries when you put your hand farther because of the air 
circulator in the mechanical parts compartment.
