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.
