4.2.1 Notes on unit location
In order to ensure the correct function of the humidier and the accessibility for maintenance, please
observe the following locating instructions:
– The Condair ABS3 humidiers are designed for wall mouting or ceiling mounting (hanging instal-
lation). Make sure that the structure (wall, pillar, ceiling, etc.) on which the unit is to be mounted has
sufcient carrying capacity and can accommodate the fastening elements.
– In order to ensure the correct function, the Condair ABS3 must be installed exactly horizontal (with
the air lter facing downward against the oor).
– Locate the unit such that the aerosol stream can spread freely. The obstruction of the aerosol stream
by objects such as tubular racks, machines, supports, etc., will result in stagnation and the formation
of turbulence which could cause condensation. Since the discharge hood of the humidier can be
turned horizontally, the aerosol stream can be directed to bypass any obstructions.
In the following table you nd the minimum distances (appoximate values), which must be maintained when positioning the Condair ABS3. The dimensions relate to a room temperature of 20 °C
and a relative humidity of 45%. At lower temperatures and/or higher relative humidity larger minimum
distances must be maintained

• the humidier and the other system components for correct xing and any damage.
• the electric installation for any damage.
If the inspection reveals any irregularities (e.g. leakage, irregular running) or any damaged components
take the Condair ABS3 out of operation as described in chapter 5.3. Then, let the damage or malfunction
be resolved by a qualied specialist or a service technician of your Condair supplier.
Note: During operation individual drops are carried along by the air ow and thrown against the hood.
This causes an audible noise, which is completely normal.
23Operation
5.3 Taking the unit out of operation
DANGER!
Hygieneproblems
If the Condair ABS3 is switched on, the unit is ushed in regular intervals independent of the humidity
demand (if ushing cycles are activated, see chapter 4.4.5.1). This reduces germs formation in the
water reservoir and in the water supply pipe caused by standing water.
Therefore let the Condair ABS3 always switched on unless you have to perform work on the unit
(e.g. performing maintenance, eliminating faults, etc.).
Proceed a follows to put the Condair ABS3 out of operation (e.g. for maintenance work, elimination of
a malfunction):
1. If the Condair ABS3 humidies right now: Set the humidity reference value on the external humidity
controller/humidistat to 0 %rh and wait until the unit has nished the ushing cycle (approx. 1 minute).
2. Turn off the service switch in the mains supply line, then secure the service switch against inadvertent switching on.
3. Close the stop valve of the water supply line.
Note: If the Condair ABS3 is not used for prolonged period of time, clean and disinfect the unit, and
cover the unit with a plastic hood.

6.1 Important notes on maintenance
Qualicationofpersonnel
All maintenance work must be carried out only by wellqualiedandtrainedpersonnelauthorizedby
the owner. It is the owner’s responsibility to verify proper qualication 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
DANGER!
Before maintenance is initiated, the Condair ABS3 must be tak en out of operation in accordance
with instructions in chapter 5.3 and protected against unintentional switching on.
WARNING!
If the Condair ABS3 is insufciently maintained ill-making germs can increase in the water reservoir
by the time and get into the ambient air.
6.2 Maintenance intervals
In order to maintain operational safety the Condair ABS3 must be maintained in regular intervals. The
time interval for the maintenance is to be adapted to the operating conditions. The hygiene status
depends mainly on the quality of the humidier water and the micro-biological and chemical composition
of the supply air. Therefore the maintenance intervals must be determined for each system separately.
The rstvisualcheckmustbecarriedoutafter200operatinghours. Depending on the encountered
hygiene status during this rst check the maintenance interval time must be decreased or increased.

26 Maintenance
6.4 Cleaning and disinfection
Proceed as follows to clean and disinfect the parts coming in contact with water:
• Use lukewarm soapy water to clean the interior and parts in contact with air and water (water reservoir,
atomizer disk, atomiser collar, aerosol discharge hood etc.). 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 reassembling the unit.
When cleaning make sure:
– not to damage the outer edges of the atomizer disk. A defective disk reduces the efciency of the
humidier and can cause damage to the bearing (unbalance).
– not to bend the lamellas of the atomizer collar. 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 components 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.
27Maintenance
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. Therefore 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.
– Donotusesolventsorotheraggressiveliquidsforcleaning.
– Do not use scouring equipment (wire brush, scouring cloth, etc.) for cleaning because they leave
scratches that encourage the growth of microorganisms.

10 Hygiene
10.1 Important notes on hygiene
Observe the local health and safety executive's technical guidance on the control of Legionella in water
systems.
The user is responsible for ensure that the water system complies with local regulations, bylaws, and
guidelines (such as the HSE ACoP L8, ASHRAE 188, VDI 6022, ISO 22000, HACCP, or equivalent).
If inadequately maintained, water systems, of which any humidier is a part, can support the growth of
microorganisms, including the bacterium responsible for Legionnaires' disease.
Any risks or hazards relating to the system, including during installation and maintenance, should be
identied by a competent health and safety representative who is responsible for introducing effective
control measures.
10.2 Hygieneriskmanagement
If cold water humidication systems are not maintained according to this manual, they present the risk
of spreading pathogenic microorganisms into the air. The Humidier distribute tiny water droplets (mist)
that are blown into the space before being absorbed into the air. If the mist was contaminated before
leaving the unit and then evaporates, these contaminants are deposited onto surfaces in the space, or
can be inhaled by occupants in the room.
Pathogens include, but not limited to, Legionella, E. coli, and viruses, may originate from contaminated
water or the equipment.
Therefore regular cleaning and disinfecting is required to reduce health risks. Refer to chapter 6 in this
manual. Do not miss or ignore the warnings in this manual.
Follow all safety precautions and local regulations.
Supply Water
Pathogens can originate from the water supply, such as a tank or water line. It is important that standing
water in a tank or in the water line is ushed frequently to prevent the buildup of contaminants, and the
water is ltered and treated.
Pathogens may also enter the humidication system from the air. A fan blows air over the water reservoir
and is mixed with aerosols when blown into the room.
InsidetheHumidier
A small risk of contamination may occur during manufacture, testing, delivery, and commissioning. Any
water that was present during these processes is considered stagnant. Ensure that all applicable components (i.e. wet surfaces, such as mist pipes, reservoirs, and hoses) of the humidication system has been
cleaned and disinfected before installation. Refer to the maintenance routines as described in chapter 6.
Note: Stagnant water may also be formed after shutting down the humidier (and after inactivity). Ensure
that the humidier is air dried for inactivity, and cleaned before restarting.
33Hygiene
10.2.1 Guidelines to keep a clean system and prevent legionella growth
• Perform a risk assessment of the water system using a competent person, and implement an appropriate monitoring and control program.
• Connect a RO-U system to a clean, potable main water supply.
• Enter a service contract that suits the needs of the company.
• Stop the system if polluted drinking water is found in the area.
• Avoid water temperatures between 20-40 °C (50-140 °F) that favor the growth of Legionella.
• If the system was stopped for more than 48 hours, complete a total system cleaning and disinfection.
• Disinfect at least once per month- and/or after every maintenance or repair.
• Analyze the water and test for harmful bacteria at least once per year.
• Conduct follow-up measurements until the system is clean if bacteria has been detected in the
system.
The Condair service team can help with expert technicians who can provide:
– Bacteriological troubleshooting on-site.
– Cleaning and disinfecting.
– Preventative maintenance.
– Repair and fault nding.
1)
– Training and guidance.
1)
Note: Condair uses a quick method for measuring bacterial activity in the water with the use of
BactiQuant. Once the water sample has been take, the bacteriological quality of the water is read
within 30 minutes, and the Condair service team will disinfect the system if necessary.
Condair follows the guidelines in VDI 6022 for CFU counts in humidiers. The CFU count in the
humidication water must not exceed 150 CFU/ml, corresponding to a maximum BQ value of 40.
Please contact your local Condair representative for further information about our services.
34 Hygiene
10.2.2 Risk Monitoring and Assessment
Water hygiene assessments must be performed at the site to determine the risk and severity of hygiene
hazards that affect the health and safety of the public. Performing a risk assessment with regular monitoring will allow procedures to be adjusted.
Ensure that the person conducting the assessment is qualied.
A typical assessment inspects the following:
• Supply water quality.
• Environment around the humidier.
• Maintenance procedures.
• Water pre-treatment options (such as using UV light, using reverse osmosis or deionized water, etc.).
Proper maintenance procedures along with recommended site controls will help ensure compliance to
local regulations and protect the public.
It is recommended to monitor the humidication system monthly. Ensure that the results of every assessment is recorded.
Failure to make adequate provision against the outbreak of disease, such as Legionnaires' disease,
may cause fatalities, illness, and liabilities.
