3.2 Description of product
3.2.1 Special version
The special version Condair 505 S is designed for direct con-
nection to the water supply. The Condair 505 S is equipped with
a oat valve and a connector for an overow pipe.
Note: The standard Condair 505 may be upgraded to the special
version at any time – please contact your Condair representative.
3.2.2 Functional description
The Condair 505 uses the atomizer principle. The suction piece
takes in the water from the reservoir. Then the whirl disk moves
the water towards the atomizer ring where it is transformed into
aerosol fog.
The vanes of the whirl disk take in the air via the radial openings
of the housing. This air stream passes by the atomizer ring and
directs the aerosol fog out of the humidier in an upward direction.
The atomizer unit is driven by a maintenance-free electric motor.
3.2.3 Accessories and options
The following accessories and options are available for the Condair 505:
505
Directionalcapvertical(“Z72”) for vertical adjustment of the
aerosol fog.

WARNING!
Use only fresh tap water or partly/fully demineralized water with a max. of 150 CFU/ml (no pathogens).
Do not use any additives.
5.2 Setting the unit into operation
• Check the unit for possible damage.
CAUTION!
If the unit is damaged do not set it into operation!
• Make sure the operating voltage of the Condair 505 (see type plate on unit) matches the local supply
voltage, then connect the unit to the mains.
The Condair 505 starts humidication without delay.
5.3 Controls in daily operation
In daily operation the water level and the humidity must be monitored on a regular basis. For monitoring
the humidity we recommend to use a hygrometer (e.g. the Condair hygrometer) placed in a suitable
location (not too close to the humidier). Disconnect the unit from the mains as soon as the desired
level of humidity is obtained.
Please consider the following directional temperature and humidity values for optimalhumidication:
Room temperature Humidity
18 °C 55 %rh
20 °C 50 %rh
22 °C 45 %rh
Note: For semiautomatic (Condair 505) and fully automatic operation (Condair 505 S) use the ap-
propriate humidier together with the humidistat H-4. The humidistat H-4 switches the humidier on
and off depending on the selected nominal humidity. The humidistat H-4 is supplied with a separate
installation manual.
5.4 Setting the unit out of service
Disconnect the humidier from the mains. Empty the water reservoir, then clean the unit following the
instructions given in chapter 6.

18 Maintenance and cleaning 2595364-B EN 1903
6.3 Cleaning and disinfection
Proceed as follows to clean and disinfect the parts coming in contact with water:
• Use lukewarm soapy water to clean the water reservoir, support disk, suction piece, whirl disk,
guiding disk, aerosol discharge hood and the segments of the atomizer ring. Then thoroughly
rinse all components with fresh cold tap water.
Note: If the components are heavily encrusted with lime, soak them in citric acid until the lime layer
is dissolved. Finally, clean the components as described above.
• Use an accepted disinfectant (see notes on cleaning agents below) to disinfect all parts cleaned
before. Let the disinfectant work for minimum 30 minutes. Then, rinse all parts with fresh cold tap
water. Make sure the parts are properly rinsed and all disinfectant has been removed, before reas-
sembling the unit.
When cleaning make sure:
– not to damage the outer edges of the whirl disk. Defective disks reduce the efciency of the humidi-
er and can cause damage to the bearing (unbalance).
– not to bend the lamellas of the atomizer ring. Bent lamellas adversely affect the atomization process.
– the inlet of the suction piece is open so that the water may pass through.
Use a cloth or a sponge moistened with soapy water to clean the motor housing. Then rub the com-
ponents with a wet cloth (clean water) several times.
If the components are heavily encrusted with lime, rub them with a cloth soaked in a citric acid solution.
Allow the acid to act for some time and then tho roughly clean the motor housing with water.
CAUTION!
Prevent the cleaning agent from getting into the electric motor. Never clean the motor housing under
the tap and never dip it in liquids of any kind.

192595364-B EN 1903 Maintenance and cleaning
Notes on cleaning and disinfection agents:
– Citric acid is available at pharmacies.
WARNING!
Citric acid can cause skin and serious eye irritation and can attack the mucous membranes. There-
fore wear protective gloves and eye protection and work in a well-ventilated room or outdoors.
Observe manufacturer's safety instructions.
– Accepted disinfectants:
– 3 % Hydrogen Peroxide solution (available at pharmacies)
– 0,1 % Sanosil S003 solution (available from Condair, order no. 2590544)
Active ingredients: 1.5% hydrogen peroxide, 0.003g/100g silver
After disinfection the components must be thoroughly rinsed with fresh cold tap water.
– Caution! Do not use solvents or other aggressive liquids for cleaning.
– Do not use scouring equipment (wire brush, scouring cloth, etc.) for cleaning because they leave
scratches that encourage the growth of microorganisms.
6.4 Replacement of defective parts
The customer must not carry out repairs other than the replacement of the following parts:
– water reservoir
– support disk
– suction piece
– whirl disk
– guiding disk
