10 Product Overview
3.2 Functional description
The Condair RS steam humidier is an atmospheric steam generator. It operates on the resistance heating
principle and is designed for direct room air humidication (with blower pack) and indirect humidication
(with steam distributor) in venti lating and air-conditioning systems.
Water supply
The water is supplied via a lter valve (accessory "Z261") to the steam humidier. It reaches the steam
cylinder via the level controlled inlet valve and the open lling cup.
Note: the open lling cup is designed in such a way, that the supply water is separated from the unit
water. That means, that no unit water can ow back into the supply water line.
Level regulation
The water level in the steam cylinder is continuously monitored with the level unit. If the water level
reaches a preset level (due to the evaporation process) the level unit supplies a signal to the controller.
This opens the inlet valve and the steam cylinder is lled up. When the preset operating level is reached,
the level unit supplies another signal to the controller to close the inlet valve.
The pressure equalizing pipe between the steam connection and the level unit ensures that the water
levels are the same in the steam cylinder and the level unit.
Steam generation regulation
The steam is produced in the steam cylinder by several resistance heating elements. An external or the
integrated continuous controller control the steam production fully variably from 0 to 100 %.
Alternatively the Condair RS can be controlled also via an On/Off controller.
Flushing
The evaporation process increases the concentration of minerals in the water of the steam cylinder. A
suitable volume of water must be ushed out of the steam cylinder from time to time and replaced by
fresh water to ensure that this concentration does not exceed a specic value unsuitable for operation.
The Condair RS consists of the following two forms of ushing:
– Automaticushingtakes place as soon as the water in the steam cylinder exceeds the upper
operating level (e.g. by foaming of the water).
– Flushing dependent on time performs the ushing process at preselected time intervals.
Automatic or time-dependent ushing takes place depending on the water quality and the operating data.
If the lowest operating level is reached during the ushing process, the inlet valve remains open until
the water level in the steam cylinder has reached the normal working level again. If the lowest operating
level is not reached, the inlet valve is closed.
Scale collector tank
The minerals precipitated by the evaporation process sink down in the steam cylinder and accumulate
in the scale collector tank, thus extending the service intervals and reducing the maintenance work.
Units designed for operation with water from a RO system or with de-ionized water do not require a scale
collector tank as RO water and de-ionized water contains only small amounts of minerals.

13Operation
4 Operation
The Condair RS steam humidier may be commissioned and operated only by persons familiar with the
Condair RS steam humidier and adequately qualied. It is the owner’s responsibility to verify proper
qualication of the personnel.
4.1 First-time commissioning
The rst-time commissioning must always be done by a service technician of your Condair representative
or a well trained and authorised person of the customer. Therefore the current manual does not provide
detailed information on this procedure.
The following steps are carried out upon rst-time commissioning in the specied order:
• Inspecting the steam humidier for correct installation.
• Inspecting the electrical installation
• Inspecting the water installation
• Inspecting the steam installation
• Flushing the water supply line.
• Conguring the control or the Condair RS, respectively.
• Carrying out test runs including checking of the control and monitoring devices.
• Filling in the commissioning protocol.
4.2 Display and operating elements

14 Operation
4.3 Commissioning after an interruption of operation
The following description outlines the start up procedure after an interruption of operation (e.g. after ser-
vicing the steam humidier). It is assumed that rst-time commissioning has been carried out properly by
the service technician of your Condair representative and the Condair has been congured accordingly.
1. When putting the steam humidier into operation the rst time or when putting the steam humidier
into operation after work has been carried out on the steam system, the operating personnel must
check whether the steam pipe is open over the entire length. To do this proceed as follows:
Remove the front door on the steam cylinder side of the Condair RS.
• Undo the upper hose clamp of the steam hose in the unit with a screwdriver and pull the hose
down to remove it from the steam connection.
• Start up the ventilation system and check whether the pressure on the open steam connector
corresponds to the pressure in the ventilation system.
DANGER!
A steam line that is reduced in cross section or completely closed will cause an excessive
increase in pressure in the steam cylinder when the unit is operating and could lead to the
risk of scalding accidents!
Therefore: If no draught or only a slight one can be detected the steam line must be checked for
blockages and reductions in cross section before continuing with commissioning and you must
ensure that the steam line is open across the entire length and through the whole cross section.
2. Examine the steam humidier and installation for possible damage.
DANGER!
A damaged unit or systems with damaged installations may present danger to human life
or cause severe damage to material assets.
Therefore: Damaged systems and/or systems with damaged or faulty installations must not be
operated.
3. Mount front doors of the unit and lock it (if applicable).
4. Open the lter valve / shut-off valve in the water supply line.
5. Switch on the electrical isolators in the mains supplies (heating and control voltage).
6. Switch on the unit switch of the steam humidier.
The steam humidier carries out an automatic system test (initialising). If a fault is detected during
the system test, a corresponding fault message is shown in the maintenance and malfunction indi-
cation eld (see chapter 5.1.2).
Iftheinitializationissuccessful, the steam cylinder lls up and a function check on the level unit
is carried out. If a fault is detected during the function check on the level unit, a corresponding fault
message is shown in the maintenance and malfunction indication eld (see chapter 5.1.2).
If the function check on the level unit is successful, the Condair RS will be in normal operating
mode and the standard operating display is shown. The heating current switches on as soon as
the humidity controller/humidistat demands humidity. The LED lights green and steam is produced
after a short delay.

6.1 Important notes on maintenance
Qualicationofpersonnel
All maintenance work must be carried out only by well qualied and trained personnel authorised by the
owner. It is the owner’s responsibility to verify proper qualication of the personnel.
General note
The instructions and details for maintenance work must be followed and upheld.
Only the maintenance work described in this documentation may be carried out.
Only use original Condair spare parts to replace faulty parts.
Safety
Some maintenance work requires removal of the unit covers. Please note the following:
DANGER!
Dangerofelectrichazard!
You may get in touch with live parts when the unit is open. Touching live parts may cause severe injury
or even lethal violation.
Prevention: Before carrying out any maintenance work set the Condair RS out of operation as described
in chapter 4.5 (switch off the unit, disconnect it from the mains and stop the water supply) and secure
the unit against inadvertent power-up.
CAUTION!
The electronic components inside the humidier are very sensitive to electrostatic discharge.
Prevention: Before carrying out any maintenance work to the electrical or electronic equipment of the
humidier, appropriate measures must be taken to protect the respective components against damage
caused by electrostatic discharge (ESD protection).
WARNING!
Danger of burning!
The water in the steam cylinder and in the scale collector tank can be hot (up to 95 °C). There is
danger of burning when the steam cylinder(s) and the scale collector tank(s) is/are dismounted
shortly after steam has been produced.
Prevention: Before carrying out any work on the steam system set the Condair RS out of operation as
described in chapter 4.5, then wait until the components have cooled down sufciently (see temperature
indication adhesive on the scale collector tank) thus preventing danger of burning.
51Maintenance
6.2 Maintenance intervals
To maintain operational safety the Condair RS steam humidier must be maintained at regular intervals.
The control software of the Condair RS features two maintenance counters one for the "Small main-
tenance" (Cleaning of the scale collector tank, only for units equipped with a scale collector tank) and
one for the "Extended maintenance" (Cleaning of the steam cylinder and othe components of the steam
and water system). The maintenance counters are set at the initial commissioning based on the water
condition on site, however the maintenance counters can be adjusted at any time later to the actual
operational conditions.
If one of the maintenance counters has elapsed, a maintenance message is shown in the standard
operating display indicating that the corresponding maintenance must be carried out.
Maintenance indication "Small maintenance"
The maintenance counter for the "Small maintenance" has elapsed.
Carry out the "Small maintenance" and reset afterwards the maintenance
counter in the "Service" submenu.
Note: for the "Small maintenance" a maintenance kit is available with all
components to be replaced when carrying the maintenance.
Maintenance indication "Extended maintenance"
The maintenance counter for the "Extended maintenance" has elapsed.
Carry out the "Extended maintenance" and reset afterwards the maintenance
counter in the "Service" submenu
Note: for the "Extended maintenance" a maintenance kit is available with all
components to be replaced when carrying the maintenance.
Important! Independently of the maintenance counters the "Small maintenance" and the "Extended
maintenance" are to be carried out at least once a year.

6.4 Removing and installing components for maintenance
6.4.1 Preparing the Condair RS for the removal of components
Before starting any removal work set the Condair RS out of operation and drain the steam cylinder and
the scale collector tank (if applicable). Proceed as follows:
1. Condair RS must be switched on. Perform a draining of the steam cylinder (see chapter 4.4.3).
Note: On units equipped with the optional drain valve for the scale collector tank, the scale collector
tank is drained simultaneously when performing a draining of the steam cylinder.
2. Set the steam humidier out of operation as described in chapter 4.5.
3. This step must be carried out only on units equipped with a scale collector tank:
• Place a sufcient large container (capacity of approx. 2.6 gal (10 litres)) below the scale collector
tank.
• Carefully open the drain valve on the bottom of the scale collector tank, then wait until no water
ows out of the drain valve.
WARNING!
Danger of burning!
The temperature of the water in the scale collector tank can be up to 203 °F (95 °C)
shortly after steam has been produced.
Therefore: wear isolating gloves and open the drain valve carefully.
If no water ows out from the open drain valve, the drain inside the scale collector tank is clogged
and the scale collector tank may not be emptied. If this is the case, wait until the temperature
indication adhesive on the scale collector tank indicates a temperature below <122 °F (<50°C)
before dismantling the tank (since the scale collector tank is lled with water).
Note: On units equipped with the optional drain valve for the scale collector tank, close drain
valve on the scale collector tank and remove hose from the connector.
4. Wait until the temperature indication adhesive on the scale collector tank indicates a temperature
<122 °F (<50°C) (temperature eld on the temperature indication adhesive is green).

Qualicationofpersonnel
Repair work must be carried out only by qualiedandwelltrainedprofessionals authorised by the
owner.
Repair work relating to the electrical installation must be carried out by an electrician or professionals
authorised by the owner.
General notes
Only use original spare parts from your Condair representative to replace defective parts.
Safety
Before starting repair work on the Condair RS set the unit out of operation and disconnect it from the
mains (see chapter 4.5).
DANGER!
Make sure the Condair RS is separated from the mains (check with voltage detector) and the shut-off
valve in the water supply line is closed.
CAUTION!
The electronic components inside the control compartment of the Condair RS are very sensitive to
electrostatic discharge.
Prevention: Before carrying out any repair work to the electrical or electronic equipment of the Con-
dair RS, appropriate measures must be taken to protect the respective components against damage
caused by electrostatic discharge (ESD protection).
7.2 Fault indication
Malfunctions during operation detected by the control software are indicated by a corresponding Warning
message (operation still possible) or Fault message (operation not longer possible) in the maintenance
and fault indication eld in the standard display of the control unit.
Warning
Temporary problems (e.g. water supply interrupted for a short time) or malfunc-
tions which cannot cause damage to the system are indicated with a warning
message. If the cause of the malfunction disappears of its own accord
within a certain period of time, the alarm message will automatically
switch off otherwise an fault message is triggered.
Note: warnings can be indicated also via the service relay of the remote op-
erating and fault indication. Therefore the warning indication via the service
relay must be activated in the communication menu of the control software
(see chapter 5.4.5).
70 Fault elimination
Fault
Operational states where further operation is not possible, or where further
operation would damage the system are indicated with a fault message, ad-
ditionally the fault indicator LED below the touch panel will lights up red. If
such a malfunction occurs, the steam production of the Condair RS will be
stopped automatically.
By pressing on the maintenance and malfunction indication eld in the standard operating display the
error list shown with all active warning and fault messages. By pressing on the corresponding Warning or
Fault entry additional information regarding the malfunction are displayed (see display on the far-right).
7.3 Malfunction list
Most operational malfunctions are not caused by faulty equipment but rather by improper installation or
disregarding of planning guidelines. Therefore, a complete fault diagnosis always involves a thorough
examination of the entire system (e.g. hose connections, humidity control system, etc.).

1. Set the On/Off switch on the front side of the steam humidier to the Off position, then switch off the
voltage supply to the steam humidier via the external disconnect switch (electrical isolator) and
secure switch in the off position to prevent it from inadvertent power up.
2. Unlock the door panel on the control compartment side of the steam humidier and remove it.
3. Swing control panel assembly open.
4. Carefully insert FAT32 formatted USB memory stick into the USB port on the control board. Make
sure that the maximum length of the memory stick does exceed 75 mm.
5. Close control panel assembly, then close the door panel of the control compartment and lock it with
the screw.
7. Remove the lock and tag from the external disconnect switch. Then, switch on external disconnect
switch to restore power to the humidier.
7. Set the On/Off switch on the front side of the steam humidier to the On position.
8. When the standard operating display appears, select the <Menu> button, then enter the password
(8808) to login.
9. Select "Service > Fault/Service History Tab > Export History". The last 40 humidier fault and
service history events are then downloaded to the memory stick as separate .csv les labelled
"WARNING_FAULT.csv" and "SERVICE_HISTORY.csv".
Note: the CSV tables can be processed with a spread-sheet program on a PC
10. Repeat steps 1 to 3, then carefully remove the USB memory stick.
11. Close control panel assembly, then close the door panel of the control compartment and lock it with
the screw.
12. Repeat Step 6 and 7 to power up the humidier.
7.5 Resetting the fault indication
To reset the error indication (red LED light, operating status indication shows "Stop"):
1. Switch off the Condair RS via the unit switch.
2. Wait approx. 5 seconds, then switch on the Condair RS again.
Note: If the fault has not been eliminated, the fault indication reappears after a short while.
