10 Product Overview
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 filter 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 filter (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 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 five spray valves (with 4 spray
circuits with double stage: Y5-Y8+Y9) or one, two, three, four or all five
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 fine drops. The air passing by the nozzles absorbs the drop thus
getting humidified. Drops not absorbed by the air is retained in the post-
evaporation elements (32) thus humidifying the air passing through the
postevaporation elements. Excess water flows 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.
Product Overview 11
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 filter the nozzle pressure is equal to the
inlet pressure, thus the pressure sensor “PS5” is not present. The pressure
after the optional sterile filter 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
filter 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
flushed 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
humidification, the flushing valve opens to empty the system. If the
conductivity in the water supply line exceeds a preset value or if the
humidification 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 flushed for a certain time with fresh RO water. During the
flushing 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.

4.3 Recommissioning after interruption of operation
The following description outlines the recommissioning procedure after an
interruption of the operation (e.g., after servicing the system). It is
assumed that first-time commissioning has been carried out properly by the
service technician of your Condair representative. Proceed as follows to
prepare the humidification 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 humidification 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 flush 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 connector 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 flushes the water system
and then goes into normal operating mode. The message is reset. 7. If the

22 Operation
4.4.5 Wash over of the ceramic plates
The ceramic wash over function is only accessible if the ceramic wash over
function has been activated in the control software (see Section 5.3.3.5).
CAUTION!
During the ceramic wash over the nozzles spray water onto the ceramic plates,
similar to when 100% demand is present. In systems with a booster pump, this
also switches on.
This process must be monitored by the operator since the humidity can
significantly exceed the desired setpoint. Over-saturation of the ceramic
plates is likely.
After the ceramic wash over is complete, any water behind the ceramic plates
must be removed if it cannot drain from there.
Note: if an error message is active flushing of the ceramic plates is not
possible.
To perform a flushing of the ceramic plates, proceed as follows:

Operation 23
4.5 Decommissioning the system
In order to take the humidification system Condair DL out of operation (e.g.,
to perform maintenance) perform the following steps: 1. Close the shut-off
valve in the water supply line. 2. Switch off <Control unit On/Off> switch on
the control unit, and if applicable deactivate control unit
via the external enable switch. 3. Disconnect then control unit from the mains
supply: switch off electrical isolator in the mains
supply line and secure electrical isolator in the “Off” position against
accidentally switching on. DANGER! Risk of electric shock!
The frequency converter in the control unit of systems with booster pump
contains capacitors. These can remain charged with a potentially deadly
voltage for a certain period of time after the control unit has been
disconnected from the power supply. Therefore, wait at least 10 minutes after
disconnecting the power supply. Then make sure the appropriate contacts on the
frequency converter and the terminals on the pump motor are free of voltage
before starting any work on these components! 4. Mind hygiene! Let the fan of
the ventilation system run until the humidification unit is dry. 5. If work
has to be carried out on the humidification unit switch off the AHU and secure
the system against accidentally being switched on.
Important information on extended periods of non-use Important! For reasons of
hygiene, we basically recommend that the control unit and the supplying
reverse osmosis system should be left switched on. With the system switched
on, the water circuit is flushed at regular intervals to eliminate standing
water and reduce the risk of contamination in the supply lines. If the
humidification system Condair DL is not be used for a longer period of time
observe the following points: Mind hygiene! Drain all water conduits.
Note: Regarding the emptying of the water supply line from the RO system
please refer to the specifications of the manufacturer of the RO system.
Remove the sterile filter, drain the water in the filter housing, dry filter
housing and install a new filter cartridge. Drain the Ag ionisation
cartridge. For safety reasons the post-evaporation elements should remain in
their working position, even if the humidifier is not used for an extended
period. This prevents the water from being sprayed directly into the duct in
case the humidifier is powered up inadvertently.
