11Product Overview
3.4 Functional description
From the reverse-osmosis system (RO system) the fully demineralized water (also called RO water or
permeate) is fed via a shut-off valve (18, by others) and a external water lter 5 µm (19, recommended,
option or by others) to the central unit (17).
In the central unit the RO water is fed via the inlet valve Y1 (11), the conductivity sensor Lf1 (14), and
the silver ionization (13) for disinfecting the water and the optional sterile lter (9) to the valve manifold
(25) with the spray valves and the drain valve Y10.
On systems type A the central unit is equipped with a booster pump (10) (controlled via the frequency
converter) which increases the water pressure to the required operating pressure of approximately
101.5-108.8 psi (7-7.5 bar) (yield load) starting from a certain humidity demand.
When a humidity demand is present the spray valves open depending on the demand:
– one or two spray valves (with 2 spray circuits: Y5-Y6),
– one, two or all three spray valves (with 3 spray circuits: Y5-Y7),
– one, two or all four spray valves (with 3 spray circuits with double stage: Y5-Y7+Y9) or
– one, two, three or all four spray valves (with 4 spray circuits: Y5-Y8) or
– one, two, three or all ve spray valves (with 4 spray circuits with double stage: Y5-Y8+Y9) or
– one, two, three, four or all ve spray valves (with 5 spray circuits: Y5-Y9).
– one, two, three, four or all six spray valves (with 5 spray circuits with double stage: Y5-Y9 + Y9.1).
The fully demineralized water is now fed to the respective spray nozzles (31) producing ne drops.
The air passing by the nozzles absorbs the drop thus getting humidied. Drops not absorbed by the
air is retained in the post-evaporation elements (32) thus humidifying the air passing through the post-
evaporation elements. Excess water ows down to the bottom of the post-evaporation unit and is led
via the trap (29) and open funnel to the wastewater line of the building.
Control
The system is controlled by an external controller (enthalpy controller recommended) or by the P/PI
controller built into the control unit.
On systems:
– with 2 spray circuits a 3-step control is provided,
– with 3 spray circuits (with or without double stage) a 7-step control is provided,
– with 4 spray circuits (with or without double stage) a 15-step control is provided,
– with 5 spray circuits (with or without double stage) a 31-step control is provided
On systems type A the booster pump is switched on at a demand of approx. 60-70 % (switching point
is dependent on the inlet pressure), and then the capacity is controlled continuously up to 100% via the
pump speed.

12 Product Overview
Monitoring
The inlet pressure and the nozzle pressure are monitored with the analogue pressure sensors "PS4" and
"PS5". On systems type B without booster pump and without optional sterile lter the nozzle pressure
is equal to the inlet pressure, thus the pressure sensor "PS5" is not present.
The pressure after the optional sterile lter is monitored with the pressure switch "PS2" on systems type
A (with booster pump), and on systems type B (without booster pump) with the pressure sensor "PS5"
since the pressure after the sterile lter is equal to the nozzle pressure.
The conductivity of the fully demineralized water is continuously monitored. If the conductivity of the
fully demineralized water exceeds the admissible range (max. 15 µS/cm), the drain valve Y10 on the
valve manifold (25) opens and the water system is ushed until the conductivity meets the preset value.
An error message is displayed or the system is stopped if the conductivity value does not reach the
admissible range within a certain period (conductivity >100 µS/cm).
Hygiene function/Flushing
To prevent standing water, each spray circuit which is not active is emptied via the corresponding spray
valve (the spray valves are connected to the drain in currentless status).
After 1 hour without humidication, the ushing valve opens to empty the system.
If the conductivity in the water supply line exceeds a preset value or if the humidication system has
been without demand for more than 23 hours, the drain valve Y10 opens and the water supply line and
the water lines in the central unit are ushed for a certain time with fresh RO water. During the ushing
additionally residual water in the spray circuits is sucked out via the built-in water jet pump (26) and is
led via the open funnel with trap (27) to the wastewater line of the building.

20 Operation
4.3 Recommissioning after interruption of operation
The following description outlines the recommissioning procedure after an interruption of the opera-
tion (e.g., after servicing the system). It is assumed that rst-time commissioning has been carried out
properly by the service technician of your Condair representative. Proceed as follows to prepare the
humidication system Condair DL for operation:
1. Examine the system components and installations for possible damage.
DANGER!
Damaged systems or systems with damaged components or installations may present danger to
human life or cause severe damage to material assets.
Damaged systems and/or systems with damaged or faulty installations must not be operated.
2. Make sure the ceramic plates are correctly located and properly sealed.
WARNING!
An unsealed post-evaporation unit may lead to severe damage of material assets.
Put the system into operation only if the ceramic plates are correctly positioned and the
post-evaporation unit correctly sealed.
3. Switch on the electrical isolator in the mains supply line (mains supply to control unit).
4. If closed, open shut-off valve in the water supply line.
5. Switch <Control unit On/Off> on the control unit to "On", and activate control unit via the external
enable switch if necessary.
6. If the humidication system Condair DL has been disconnected from the mains for more than 48
hours the message "Out of Commissioning" appears. If this is the case proceed as follows:
• Switch off control unit via the <Control unit On/Off> switch.
• Close shut-off valve in the water supply line.
• Disconnect the water supply line from the connector on the central unit.
• Lead the open end of the water supply line into open funnel of the waste water line of the build-
ing.
• Open the shut-off valve in the water supply line and ush the supply line for at least 5 minutes.
Close shut-off valve in the water supply line again. Reconnect the water supply line to the con-
nector on the central unit and open the shut-off valve.
• Switch on control unit via the <Control unit On/Off> switch.
Note: After switching on the control unit the "Out of Commissioning" message appears again. After
5 minutes, the Condair DL automatically ushes the water system and then goes into normal operat-
ing mode. The message is reset.
7. If the sterile lter has been replaced, deaerate the sterile lter as described in Section 6.6.
The humidication system Condair DL is now in normal operating mode and the home screen is
shown in the display.
Note: Further information on the operation of the Condair DL control software can be found in Section 5.
