12 Product overview
3.4 Functional description
The Condair MD is based on the principle of the steam pressure difference between the dry air in the
duct and the water in the humidier. In this process pure steam diffuses through a semi-permeable
diaphragm of the humidier unit and humidies the duct air.
Water supply
The building fresh water supply is fed to the hydraulic unit via a shut-off valve and, depending on the
water hardness, via a water treatment system (reverse osmosis system Condair RO-HS). The water
reaches the water tank via the level-controlled inlet valve and the open ll cup.
Note: the open ll cup is designed so that the supply water is separate to the device water and device
water is unable to return to the supply line.
The supply water must meet valid drinking water specications as per EN 1717 and SVGW/DVGW.
The permissible supply water temperature is between 8°C and 30°C and the supply pressure between
1.5 and 5.0 bar.
Water heating
Depending on the humidity demands the water towards the humidier unit must be heated to between
20°C and 40°C for an efcient operation of the Condair MD. With the Condair MD, the humidier wa-
ter is heated by a heat exchanger integrated in the hydraulic unit, which is fed by the water of a oor/
wall-based heating with recirculation pump or a convection circuit with recirculation pump. If the water
temperature in the water tank falls below 27°C, the water is heated to the required temperature by the
heating element integrated in the water tank.
Level control
The level within the water tank is permanently monitored by a level sensor. If the water level drops below
a specied level (as a result of the humidication process), the level sensor sends a signal to the control
system. The control system opens an inlet valve and the water tank is topped up. Upon reaching the
specied operating level the level sensor once again sends a signal to the control system and the inlet
valve is closed.
Water temperature throughput quantity control
The water temperature and water throughput rate through the humidier required for a certain humidity
demand is detected by a control circuit within the control system on the basis of the humidity demand
and the combined temperature and throughput sensor installed in the humidier unit water circuit before
it is set to the corresponding values.
Humidity control
The humidity demand is determined by the humidity setpoint adjusted by the user and a humidity sensor
installed in the supply air duct. The water temperature and water throughput rate is controlled accord-
ingly on the basis of the determined humidity demand.

13Product overview
Draining
As the humidier unit of the Condair MD exclusively outputs water molecules to the duct air, the minerali-
sation within the water contained in the internal water circuit increases (particularly in the event of opera-
tion with untreated drinking water). A corresponding water quantity must be regularly drained from the
water tank and replaced by fresh water to make sure this concentration does not exceed a certain value.
During the draining process, the drain valve is opened for a certain time and the inlet valve opens with
a delay. If the lowest operating level within the water tank is reached during the draining process, the
inlet valve remains open until the water level in the water tank has once again reached the normal op-
erating level.
Periodic rinsing
In "Humidication switched On" mode and in "Humidication switched Off" mode the supply line and the
internal water system of the Condair MD hydraulic system is ushed with fresh tap water every 47 hours
according to a xed schedule as per VDI 6022. For this reason, the water supply to the hydraulic unit
must also always be open outside the humidication season and the device must not be disconnected
from the mains power and/or be switched off (exception: device is being serviced). Outside the humidica-
tion season the Condair MD can be operated in "Humidication switched Off" mode (see Section 5.6.2).
Note: if the Condair MD has to be switched off for a prolonged period of time, please note the informa-
tion in Section 5.4.

14 Initial commissioning
4 Initial commissioning
This section describes the initial commissioning of the Condair MD. Commissioning of any purchased
options (e.g. reverse osmosis system Condair RO-HS) is described in the separate instructions for
these options.
4.1 Notes on initial commissioning
Initial start-up must be performed by suitably qualied and trained Condair or Condair partner service
technicians familiar with the hazards involved and the requirements for hygienic work only.
DANGER!
Risk of electrocution
Individual work steps during the initial commissioning of the Condair MD must be carried out with the
hydraulic unit switched on and opened. If the hydraulic unit is open and switched on, users may come
into contact with live parts. Touching live parts may cause severe injury or death.
For this reason: Such steps must exclusively be performed by trained Condair service technicians or
Condair trained personnel familiar with the hazards involved.
4.2 Checking and preparing the system for the initial commissioning
Note: The following procedure for checking and preparing the system for the initial commissioning refers
to a system with internal control system. For systems with external control system, please contact your
Condair partner.
1. Switch off the ERV and secure it against reactivation.
2. Check the ERV lter:
Install at minimum ISO Coarse 80% lters (recommended: ISO ePM1 50%) in the ERV to ensure
hygienic operation of Condair MD. We generally recommend replacing the lters before initial commis-
sioning of Condair MD. In the event of visible contamination (discolouration, traces of dust, streaks,
etc.), the lters must always be replaced before starting up Condair MD.
3. Check electrical installations (see also the Condair MD installation manual):
 Has the mains socket been correctly positioned so that the hydraulic unit can be connected via
the integrated mains connection cable?
 Has the mains socket been correctly fused (10 A slow-blow fuse) and connected via an RCD
switch (30 mA)?
 Has the humidity sensor been correctly positioned (correct installation position, sensor mounted
in extract air duct?) and correctly connected to the terminals of terminal block X6 on the driver
board in the hydraulic unit?

15Initial commissioning
 Has the optional maximum humidistat been correctly positioned (correct installation position,
installed at a minimum distance of 300 mm downstream of the humidier unit in the supply air
duct?) and correctly connected to the terminals of terminal block X5 on the driver board in the
hydraulic unit?
 Has the optional air ow monitor been correctly positioned (correct installation position, installed
at a minimum distance of 200 mm upstream of the humidier unit in the supply air duct?) and
correctly connected to the terminals of terminal block X4 on the driver board in the hydraulic
unit?
 Has the optional oor leak sensor been placed correctly (below the hydraulic unit) and correctly
connected to the terminals of terminal block X4 on the driver board in the hydraulic unit?
 Is the leak sensor cable from the hydraulic unit connected to the humidier unit?
 Has jumper "JP4" been set to 24V?
 Have all cables been routed into the hydraulic unit via cable glands?
4. Carry out a visual inspection of the hydraulic unit (see also the Condair MD installation manual):
 Has the fresh water supply pipe been correctly connected and tightened?
 Has a shut-off valve been installed in the fresh water supply pipe?
 Has the wastewater pipe been routed correctly (min. continuous slope of 15%) and routed into
an open drain funnel with siphon (by others)? Has a minimum distance of 2 cm been maintained
between the drain funnel and the end of the drain pipe?
 Has the supply/return pipe of the heating water been correctly connected and tightened? Are the
connections on the inside of the housing still tightly fastened? Have the necessary ttings (e.g.
shut-off valves) been installed?
