ITEMS TO CHECK WHEN MAKING ADJUSTMENTS
Water:
Determine the proportion of calcium and bicarbonate in the water,
and its pH level. This information can be obtained from a water
analysis or from the local water company. Enter the values obtai-
ned in chart 1 on page 4 to determine which zone the water can
be classified.
If the water quality is in zone 4 a water softener must be used.
Testing operation of humidifier:
– Turn on the external switch.
– Give the start signal to the humidifier by closing input TF1
(if this signal is interrupted the humidifier will stop and the water
will drain out).
– The tray should only start to fill with water when there is a need
for humidification, i.e. when the RH1 input closes.
Now check:
– that the humidifier starts to fill with water.
– that the pump starts and pumps water (input RH1 must be
closed). If there is no water flow, change the direction of rotation,
see figure 3.
– Preset the required supply water flow rate according to Table 3.
This is done by setting the adjustment screw on the flow con-
troller, see figure 4.
– that water sprays out of all the holes in the spray pipe(s).
Use a needle to clear any clogged holes. If the pipe is clogged
with dirt, remove the end plugs, pos. 16, fig. 1, clean the spray
pipe with a round brush, then flush it clean.
– that the supply flow stops when the water reaches level A.
– that the water bleed-off rate is correct. Open the outlet valve,
figure 2, by holding in the left arrow key on RC1. When the water
level has fallen below level B the valve should open fully and
the display should show ”Emptying”. When the water drops
below level C the water inlet should open, and after the preset
time the drain valve should start to close. When the water
reaches level C the pump should stop briefly. The tray will then
refill with water.
Droplet eliminator
The droplet eliminator must be installed in the correct direction of
the air flow, see the arrow on the droplet separator.
Table 3 gives the amount of water that the circulation pump must
be set to. It is not the water consumption.
