4 - HYDRAULIC CONNECTIONS
IDENTIFYING THE CHARACTERISTICS OF THE HUMIDIFIER:
With run-through water, type P.
With water circulation by pump, type R.
Thickness of the wet deck: 150mm.
PRELIMINARY OPERATIONS:
Connect the humidifier to the mains water supply.
Fit a trap to the tank drain.
Connect the electric pump to the mains power supply, using
EC compliant equipment.
Caution: the wet decks are fitted in the humidifier in a pre-set
position in reference to the opposing flows of air and water.
Incorrect positioning will affect correct operation and may cause
water to be dragged into the sections downstream.

4.13 RUN-THROUGH WATER HUMIDIFICATION
The humidifier is complete with a constant flow valve.
To drain the water, use a drain trap and do not decrease
the diameter of the drain pipe to the sewerage, so as to
avoid flooding or unpleasant odours.
Check, after 5 minutes of operation, that the wet deck is
completely wet.
When new, the wet deck will release foam for a short time
only.
4.12 HUMIDIFICATION WITH WATER CIRCULATION
Fill the water tank and adjust the float valve so that it is
closed when the level of water is around 15mm below the
overflow.
Check, after 5 minutes of operation, that the wet deck is
completely wet.
When new, the wet deck will release foam for a short time
only.
The evaporation of water causes an increase in the con-
centration of lime scale, and the air carries dust that cau-
ses slurry and the formation of algae; to reduce these pro-
blems, use the bleed valve.
4.14 SPRAY NOZZLE HUMIDIFICATION
Connect the humidifier to the water distribution network.
Fit the tank drain pipe with a trap.
A preliminary operation involves filling the tank using the
float valve or the quick fill, checking that this occurs
correctly. The float must shut-off the supply of water when
the level is two centimetres below the overflow.
If necessary, adjust the arm of the float.
It is good practice to clean the humidifier equipment for
the first time according to the following instructions:
Operate the electric pump for half an hour, empty the
water collection tank.
Check whether the nozzles are blocked, clean the water
inlet filter.
Check the operation of the drain function so as to avoid
the concentration of salts and pollutants in the water in the
tank: the drain function must change all the water in the
tank each week, and more frequently in special cases.
Check the position of the water filter.
Check the seal of the tank, which may have been
damaged during transport.
