Functional description
The Nortec RS steam humidifier is an atmospheric steam generator. It operates on the resistance heating
principle and is designed for direct room air humidification (with blower pack) and indirect humidification
(with steam distributor) in venti­lating and air-conditioning systems.
Water supply
The water is supplied via a (filter) valve (by others) to the steam humidifier. It reaches the steam cylinder
via the level controlled inlet valve and the open filling cup.
Note: the open filling cup is designed in such a way, that the supply water is separated from the unit
water. That means, that no unit water can flow 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 filled 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. Either an external,
or the integrated continuous controller, control the steam production fully variably from 0 to 100 %.
Alternatively the Nortec 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 flushed out of the steam cylinder from time to time and replaced by
fresh water to ensure that this concentration does not exceed a specific value unsuitable for operation.
The Nortec RS consists of the following two forms of flushing:
–
Automatic flushing 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 flushing process at preselected time intervals.
Automatic or time-dependent flushing takes place depending on the water quality and the operating data.
If the lowest operating level is reached during the flushing 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.

The first-time commissioning must always be done by a service technician of your Condair representative
or a well trained and authorized person of the customer. Therefore the current manual does not provide
detailed information on this procedure.
The following steps are carried out upon first-time commissioning in the specified order:
• Inspecting the steam humidifier for correct installation.
• Inspecting the electrical installation
• Inspecting the water installation
• Inspecting the steam installation
• Flushing the water supply line.
• Configuring the control or the Nortec RS, respectively.
• Carrying out test runs including checking of the control and monitoring devices.
• Filling in the commissioning protocol.

DANGER!
Risk of electric shock!
After switching off the unit switch, there is still live voltage inside the control compartment of the
Nortec RS. Therefore, before opening the unit the steam humidifier must be always separated
from the mains supplies (heating and control voltage) via the electrical isolators.
Operation
13
4.3
Commissioning after an interruption of operation
The following description outlines the start up procedure after an interruption of operation (e.g. after servicing the steam humidifier). It is assumed that first-time commissioning has been carried out properly by
the service technician of your Condair representative and the Nortec RS has been configured accordingly.
1. When putting the steam humidifier into operation the first time or when putting the steam humidifier
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 Nortec 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 humidifier 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 filter 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 humidifier.
The steam humidifier carries out an automatic system test (initializing). If a fault is detected during
the system test, a corresponding fault message is shown in the maintenance and malfunction indication field (see chapter 5.1.2).
If the initialization is successful, the steam cylinder fills 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 field (see chapter 5.1.2).
If the function check on the level unit is successful, the Nortec 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.

Operation
4.5
Taking the unit out of operation
In order to take the Nortec RS steam humidifier out of operation (e.g. for maintenance purpose), perform
the following steps:
1. Close the shut-off valve in the water supply line.
2. If you have to carry out maintenance work on the steam cylinder and/or on the scale collector tank
perform a cylinder draining (see chapter 4.4.3).
3. Switch off unit switch of the steam humidifier.
4. Disconnect steam humidifier from the mains: Switch off both electrical isolators in the mains
supply lines (heating and control voltage) and secure switches in "Off" position against accidentally
being switched on, or clearly mark the switches.
5. If you have to carry out maintenance work on the steam cylinder, empty the scale collector tank via
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).
Therefore: wear isolating gloves and open the drain valve carefully.
If no water flows 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 filled with water).

Maintenance intervals
To maintain operational safety the Nortec RS steam humidifier must be maintained at regular intervals.
The control software of the Nortec RS features two maintenance counters one for the "Small maintenance" (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.

Removing and installing components for maintenance
6.4.1
Preparing the Nortec RS for the removal of components
Before starting any removal work set the Nortec RS out of operation and drain the steam cylinder and
the scale collector tank (if applicable). Proceed as follows:
1. Nortec 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 manual draining of the steam cylinder.
2. Set the steam humidifier 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 sufficient large container with a 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
flows 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 flows 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 filled 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 field on the temperature indication adhesive is green).

Important notes on fault elimination
Qualification of personnel
Repair work must be carried out only by qualified and well trained professionals authorized by the
owner.
Repair work relating to the electrical installation must be carried out by an electrician or professionals
authorized 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 Nortec RS set the unit out of operation and disconnect it from the
mains (see chapter 4.5).
DANGER!
Make sure the Nortec 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 Nortec RS are very sensitive to
electrostatic discharge.
Prevention: Before carrying out any repair work to the electrical or electronic equipment of the Nortec 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 field in the standard display of the control unit.
Warning
Temporary problems (e.g. water supply interrupted for a short time) or malfunctions 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 operating 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).
