LQQA Humidifier, for circulated water

Maintenance adjustments 

 

Water:

Determine the calcium and bicarbonate content and the 

pH value of the water. These values can be obtained 

from a water analysis or from the local water authority. 

Plot the values of bicarbonate, calcium and pH in chart
1 on page 5 to determine in which zone the water can

be classified. If the water is of zone 4 type, it should 

be softened.

Level monitors fig. 2

Level monitor A:   Level monitor A: Closes the water 

 

supply valve when the water  

 

 

reaches max. level A.

Setting A:  

65 mm from the upper edge of the  

 

water tray (sizes 60–84). 

Level monitor B:   Opens the drain valve for water

 

bleed-off.

Setting B:  

The zone value obtained (see page 5)

 

determines at which setting level

 

monitor B (Fig. 2) is to be preset. 

 

Level monitor C:   Stops the circulation pump and opens

 

the water supply valve if the water

 

level drops below level C.

Setting C:  

25 mm from the bottom of the water

 

tray (sizes 60–84) 

 

Level relays:

NR 1, NR 2 and NR 3 are shown in Fig. 7. The level

relays are preset at a sensibility of 40 kΩ. If softened

water is used and the level monitors don’t work, the

sensibility setting can be increased to 100 kΩ.
