3 Hygiene

3.1 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 to ensure that the water system complies with local regulations, bylaws, and guidelines (such as the HSE ACoP L8, VDI 6022, ISO 22000, HACCP, or equivalent). If inadequately maintained, water systems, of which any humidifier 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 identified by a competent health and safety representative who is responsible for introducing effective control measures.

3.2 Hygiene Risk Management

Cold water humidification presents the risk of spreading pathogenic microorganisms into the air. The Ultrasonic Humidifier and Ultrasonic Blower Pack 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 are otherwise inhaled or redistributed into the ventilation system.

Pathogens include, and are not limited to, Legionella, E. coli, and viruses, and may originate from contaminated water, air, and equipment.

Regular cleaning and disinfecting is required to reduce health risks. Refer to "Hygiene Risk Man-

agement" above for more information on managing hygiene hazards.

Follow all safety precautions and local regulations. Refer to "For Your Safety" on page9.

There are multiple points in the humidification system where a contamination can occur. It is the responsibility of the customer and of Condair to ensure that health hazards due to contamination are reduced to acceptable levels. The use of a hygiene risk assessor is recommended.

Regularly clean and maintain the humidifier and its components, and do NOT miss or ignore the warnings in this manual and service messages displayed on the humidifier.

Hygiene|12

Supply Air and Water

Pathogens can originate from the water supply, such as a tank or water line. It is important that standing water in the tank or in the water line is flushed frequently to prevent the buildup of contaminants, and the water is filtered and treated. Refer to "Water Supply Requirements" for source water recommendations.

Pathogens may also enter the humidification system through the ventilation system or from within the humidifier space. A fan blows air out of the water reservoir into flexible tubes, and further into a blower pack and into the atmosphere. Contaminated air can join the mist, so it is recommended to use air filters in the ventilation system, in the humidifier, and in the Ultrasonic Blower Pack. Ensure to use the supplied air filters at all times and replace them regularly (as recommended in the Ultrasonic Humidifier Maintenance and Operation Manual).

Inside the Humidifier

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 flexible tubes, reservoirs, and hoses) of the humidification system has been cleaned and disinfected before installation. Refer to the maintenance routines as described in

"Maintenance List" on page39., and "Maintenance Procedures" on page42.

2588787_A_EN_1811_US_OM

Page 13

The humidifier possess a UV assembly that uses ultraviolet radiation to kill microorganisms that enter the unit from the water supply. The UV assembly is powered by the humidifier and must be inspected and replaced regularly.

To prevent standing water inside the unit, the humidifier software activates a flushing cycle that empties the water from hoses and reservoirs into the drain. The humidifier is replenished with new water.

During normal operation and use, standing water may be present in cracks, scratches, and joints within the reservoir, flexible tubes, mist channels, and hoses. To prevent stagnant water from accumulating, flexible tubes and channels, water reservoirs, and hoses must be disassembled regularly and cleaned. Reduce the frequency of microscopic scratches and cracks by using nonabrasive cleaning materials and agents when cleaning the humidifier (i.e. do NOT use a hard or metallic brush). Refer to "Cleaning

and Disinfecting" on page38. Follow regular maintenance routines as described in "Maintenance List" on page39.

Note: Stagnant water may also be formed after shutting down the humidifier (and after inactivity). Ensure that the humidifier is air dried for inactivity, and cleaned before restarting.

3.2.1 Guidelines to Keep a Clean System and Prevent Micro-organism Growth

l Perform a risk assessment of the water system using a competent person, and implement an

appropriate monitoring and control program.

l Connect a RO system to a clean, potable main water supply.

l Ensure that the system is cleaned and/or flushed regularly.

l Ensure that the buffer tank is clean and sterile before use.

l Enter a service contract that suits the needs of the company.

l Stop the system if polluted drinking water is found in the area.

l Avoid water temperatures above 20 °C (68 °F). Temperatures between 20-60 °C (68-140 °F)

favor the growth of Legionella.

l Do not stop the system unless it is faulty or leaking (to avoid water stagnation).

l If the power to the system is interrupted (such that the unit fails to flush or drain) for more than 48

hours, complete a total system disinfection.

l Refrain from closing sections of the system, unless there is a leakage or fault (to avoid water

stagnation).

l Disinfect at least once per year, and after every maintenance or repair.

l Analyze the water and test for harmful bacteria at least once per year.

l 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:

l Bacteriological troubleshooting on-site*.

l Cleaning and disinfecting.

l Preventative maintenance.

l Repair and fault finding.

l Training and guidance.

Note: * Condair uses a quick method for measuring bacterial activity in the water with the use of BactiQuant (BQ). Once the water sample has been taken, the bacteriological quality of the water is read within 30 minutes, and the Condair service team will disinfect the system if necessary.

Please contact your local Condair representative for further information about our services.

3.3 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

2588787_A_EN_1811_US_OM

Hygiene|13

Page 14

monitoring will allow procedures to be adjusted.

Ensure that the person conducting the assessment is qualified.

A typical assessment inspects the following:

l Supply water quality. Refer to "Water Supply" on page19.

l Environment around the humidifier.

l Maintenance procedures. Refer to "Maintenance Procedures" on page42 .

l 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 humidification system weekly, and then monthly once satisfactory levels are maintained.

Ensure that the results of every assessment is recorded.

IMPORTANT! Failure to make adequate provision against the outbreak of disease, such as Legionnaires' disease, may cause fatalities, illness, and liabilities.

4 Product Description

4.1 General Description

The Ultrasonic Humidifier is a steam-less humidifier. To humidify the space, the Ultrasonic Humidifier creates mist using piezoelectric transducers. Mist is expelled from the unit with internal fans, and an Ultrasonic Blower Pack (if installed), into the space. Mist is then absorbed into the air.

The Ultrasonic Blower Pack comes in 4 different output capacities; 3 kg/h (6.6 lb/h); 6 kg/h (13.2 lb/h); 9 kg/h (19.8 lb/h); and 18 kg/h (39.6 lb/h).

There are two housing sizes; medium and large. The medium and large units can supply mist to other rooms or directly into the space using any installed Ultrasonic Blower Packs. The large units require two Ultrasonic Blower Packs. Refer to "Technical Data" on page19 and "Operating Data" on page23 for more information about capacity, power and water consumption.

4.2 Functional Description

The Ultrasonic Humidifier is an adiabatic unit that uses transducers in the humidifier's water reservoir to create a fine mist using high-frequency vibrations (1.7 MHz).

Treated water enters the humidifier's reservoir from an inlet located at the bottom of the unit. The water that enters the humidifier's reservoir must be treated to remove minerals, bacteria and fungi, and should otherwise be pure to prolong the service cycle of the unit and, above all, safeguard the public. An accumulation of minerals will result in scale, and an accumulation of bacteria and fungi will result in unhygienic conditions in the space. Refer to "Hygiene" on page12.

Transducers in the reservoir receive a signal for humidification and will activate. The transducers will vibrate in the water to create a mist of fine water particles. The mist rate is controlled through the humidifier's control board, and may be modulated on demand or on humidity signal.

The mist is blown from the reservoir into flexible tubes that exit from the top of the humidifier. The mist is channeled directly into the Ultrasonic Blower Pack. The water particles in the mist are then absorbed into the air and increase the relative humidity of the space.

Condensate formed in the flexible tubes between the blower pack and the humidifier re-enters the reservoir where it can be reused.

Water is drained from the reservoir through an outlet located at the bottom of the unit.

Water Supply

Water enters the humidifier through the fill valve into the fill cup with integral air gap, and then ﬂows down through the UV light into the water reservoir

Water Level Monitoring

The water level in the reservoir is continuously monitored with a level sensor. If the water level drops below the sensor switching point, from normal operation, the sensor supplies a signal to the controller. This opens the inlet valve and the water reservoir is filled. When the water level reaches the operating level the sensor supplies a signal to the controller to close the inlet valve.

UV Pre-Treatment

Water enters the UV reactor, from the inlet, and is disinfected with UV radiation in the UV reactor in the UV assembly. The water exits the UV assembly into the fill cup which monitors the water level.

Mist Generation

When the humidifier receives a signal to supply mist, the unit fan and the piezoelectric transducers start operating. The fine mist is blown out of the humidifier outlets by the unit fan.

2588787_A_EN_1811_US_OM

Product Description|17

Page 18

Air Supply

Air supplied to the humidifier comes from the space surrounding the humidifier and through the humidifier. The air should be filtered and clean to prevent contaminating the mist with microorganisms and dust.

The use of the supplied air filters (recommended) is advised for the Ultrasonic Humidifier and Ultrasonic Blower Pack.

Flushing

To prevent the growth of bacteria in the unit, a flush cycle is implemented to replace the content of the water reservoir with fresh water. The flushing is carried out at an adjustable time interval.

The production of mist is interrupted during the flushing process. The drain valve will open and the reservoir will be completely discharged though the water discharge (drain) connection. The inlet valve will open and flush out any stagnant water in the water supply line. The drain valve is closed and the inlet valve is closed after the water level inside the reservoir reaches the normal operation level. After a flush cycle the unit resumes normal operation.

Control

Mist production can be controlled using the continuous proportional (P) or the proportional-integral (PI) controller internal to the humidifier, or an external modulation controller, or with an On/Off control signal from an external humidistat.

7.4 Shutting Down the Unit

Strictly observe all safety precautions and perform only the tasks described in this manual. Refer to "For

Your Safety" on page9.

IMPORTANT! Avoid unpowering your unit. To stop humidification, set your demand to 0. This will leave your unit powered and in 'standby' mode to allow your unit to flush regularly and prevent microbial growth.

To shut down the Ultrasonic Humidifier:

1. Shut off the water supply to the humidifier.

2. Make a note of the fault code, if any, displayed on the Home screen.

3. Set the On/Off button to the Off position.

4. Wait for the humidifier to drain the reservoir and shut down. The drain valve will remain open for 70 seconds to drain the unit. After this period, the drain valve will close.

5. Disconnect the power supply to the humidifier at the external disconnect switch. To prevent accidental power-up, lock out and tag out.

7.5 Remote Monitoring

The Ultrasonic Humidifier can be monitored remotely by connecting the fault relay to a remote monitoring system.

7.6 Draining the Unit

To drain the reservoir:

1. Turn off the humidifier by pressing the On/Off button at the front of the unit. Refer to "User Inter-

face Controls" on page24. The drain valve will open and remain energized for 70 seconds to

fully drain the reservoir (independent of the current water level in the unit).

During a flushing cycle, the unit will drain from full. If the water level sensor indicates a full tank after 70 seconds has passed, the unit will enter a Drain Fault and stop operating.

Note: There is no manual drain valve. The drain valve is operated with electricity and is normally closed. In addition to its main power source, it is also powered by the back-up battery (when the mains power is not available). Ensure that the back-up battery is installed and fully functional or the unit will not drain during an outage, and will create stagnant water.

8.4.2 Cleaning, Removing, and Installing the Water Reservoir

Cleaning and Disinfecting Considerations: Water Reservoir

The water reservoir houses very delicate piezoelectric transducers that may break during cleaning/removal/installation. To avoid damaging the transducers, avoid removing the water reservoir from the unit unless it is necessary. This may impact cleaning/disinfecting procedures, so care must be taken:

l Gently spray the reservoir with clean water to rinse away residue, or allow the reservoir to fill

and drain several times to rinse it out.

l Clean with a soft cloth.

l After cleaning with soap, instead of scrubbing off scale, soak the water reservoir in citric acid

(pH2) for 15-20 min. Approximately 3 L (0.8 gal) is necessary to fill the reservoir without it overflowing through the fan opening.

l To disinfect, spray the water reservoir (drained) with hydrogen peroxide (0.1% solution) and

allow to air dry. The unit may be wiped with disinfectant, however, care must be taken that the sensitive piezoelectric transducers are not damaged.

If the reservoir should be removed from the humidifier, refer to the steps in "Removal" below.

Citric acid can be ordered from Condair (PN: 2589797).

The following instructions can only be performed while the water reservoir is removed from the unit. It is suggested to also inspect and perform maintenance on the UV assembly and transducers before the water reservoir is reinstalled into the humidifier.
