Safety Precautions that Must be Observed
DANGER!
Risk of electric shock!
The unit is electrically powered by the humidifier. Using the On/Off switch on the humidifier to
shut down the unit will NOT shut off power to the control cabinet. Live parts may be exposed when
the access panels or doors are removed. Touching live parts may cause severe injury or even
death.
Prevention: The unit must be connected to the humidifier only after all mounting and installation work
has been completed and checked for correct workmanship. The humidifier MUST be connected from
the mains only after work has been completed on the humidifier or blower pack, and the access pan-
els/doors are closed and fastened securely.
Only qualified personnel should perform maintenance or repairs on the unit.
Follow any lockout procedures when servicing the unit.
DANGER!
Putting objects or body parts into the fan can result in serious injury or damage to equip-
ment!
The fan consists of rotating blades. Putting objects into the fan will affect the proper functioning of
the unit, causing damage to the object and the equipment, and will become a safety hazard for
people in the vicinity of the unit.
Prevention: Avoid placing objects and body parts into the fan, and if work must be performed, ensure
that the unit is properly shut down.

WARNING!
Risk to Hygiene and Health!
Improper and infrequent maintenance of the unit presents the risk of spreading pathogens (such
as bacteria , viruses, and parasites) originating from contaminated water, air, and equipment. Fail-
ure to reduce the risks increases the likelihood of causing injuries (requiring medical care), infec-
tion, and death.
Prevention: Use, regularly clean, and replace the air and water inlet filters. Regularly flush and dis-
infect the humidifier, the blower pack, and their components (tanks, hoses, reservoirs, etc.). Use pot-
able, treated water (potable, R.O., or D.I.).
Follow regular maintenance routines as described in "Maintenance List" on page36. Follow local reg-
ulations.
WARNING!
Do NOT leave the unit without power. Risk of contamination.
Do NOT leave the unit unpowered for more than 48 hours, or else a total system disinfect will be
required. Without power, the system will not flush properly, resulting in standing water and con-
ditions that may promote the growth of micro-organisms.
Prevention: Leave your unit powered on. If you do not need humidification during the 48 hours, set
the humidifier to standby or set the demand to 0.

3 Hygiene
Hygiene |10 2588705_A_EN_1811_UB_IOM UB
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 con-
taminated 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8.
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 warn-
ings in this manual and service messages displayed on the humidifier.
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.
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 sup-
plied air filters at all times and replace them regularly (as recommended in the Ultrasonic Humidifier
Maintenance and Operation Manual).
3.2.1 Guidelines to Keep a Clean System and Prevent Micro-organism Growth
lPerform a risk assessment of the water system using a competent person, and implement an
appropriate monitoring and control program.
lConnect a RO system to a clean, potable main water supply.
lEnsure that the system is cleaned and/or flushed regularly.
lEnsure that the buffer tank is clean and sterile before use.
lEnter a service contract that suits the needs of the company.
lStop the system if polluted drinking water is found in the area.

lAvoid water temperatures above 20 °C (68 °F). Temperatures between 20-60 °C (68-140 °F)
favor the growth of Legionella.
lDo not stop the system unless it is faulty or leaking (to avoid water stagnation).
lIf 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.
lRefrain from closing sections of the system, unless there is a leakage or fault (to avoid water
stagnation).
lDisinfect at least once per year, and after every maintenance or repair.
lAnalyze the water and test for harmful bacteria at least once per year.
lConduct 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:
lBacteriological troubleshooting on-site*.
lCleaning and disinfecting.
lPreventative maintenance.
lRepair and fault finding.
lTraining 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 mon-
itoring will allow procedures to be adjusted.
Ensure that the person conducting the assessment is qualified.
A typical assessment inspects the following:
lSupply water quality. Refer to "Technical Data" on page16.
lEnvironment around the humidifier.
lMaintenance procedures. Refer to "Maintenance List" on page36.
lWater 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 Legion-
naires' disease, may cause fatalities, illness, and liabilities.

4.1 General Description
The Ultrasonic Blower Pack is used along with an atmospheric mist generating humidifier to distribute
very fine water droplets directly into local areas or into spaces that do not have a built-in air distribution
system. The Ultrasonic Blower Pack must be mounted directly on the Ultrasonic Humidifier, or remotely
mounted on suitable surfaces in the space. Large ultrasonic humidifiers, with capacities 18 kg/h (40
lb/h) use two Ultrasonic Blower Pack units. Refer to Figure 1 - below.

4.3 Functional Description
The Ultrasonic Blower Pack consists of:
lmetal housing
lelectric cable (to connect to the humidifier)
ltwo 24 VDC fans (one top fan and one bottom fan)
lan optional air filter kit (comes with 4 metal-framed filters)
la pressurized box
la mist channel
When the Ultrasonic Humidifier is powered on, the safety relay closes and permits the humidifier to gen-
erate mist when it receives a demand signal. The Ultrasonic Blower Pack is controlled through the con-
trol board of the Ultrasonic Humidifier and receives an ON or OFF signal. The mist is generated in the
ultrasonic humidifier and travels through the connection tubes to the blower pack. From there, the mist
travels through the blower pack's mist channel and is discharged through the front of the blower pack.
The exiting mist is propelled into the space by the air blown out from the pressurized box. The turbulent
air causes mixing and quick absorption between the blown out air and mist streams.
Blower pack fans provide feedback to the ultrasonic humidifier through the connection cable. This feed-
back allows the humidifier to cease mist generation when a blower pack fan fails. This allows the entire
system to shut down safely and avoids wetting in the space. A warning message "Blower pack not con-
nected" will display on the humidifier LCD display.

19 |Installation and Planning 2588705_A_EN_1811_UB_IOM UB
WARNING!
Do NOT leave the unit without power. Risk of contamination.
Do NOT leave the unit unpowered for more than 48 hours, or else a total system disinfect will be
required. Without power, the system will not flush properly, resulting in standing water and con-
ditions that may promote the growth of micro-organisms.
Prevention: Leave your unit powered on. If you do not need humidification during the 48 hours, set

7.1.1 Installation Overview
The Ultrasonic Blower Pack can be installed remotely with any Ultrasonic Humidifier, or mounted dir-
ectly onto the Ultrasonic Humidifier (large units excluded -- the Ultrasonic Blower Pack can only be
installed remotely on large Ultrasonic Humidifiers). Direct-mounting is currently unavailable for large
Ultrasonic Humidifiers. Figure 5 - below shows typical mounting configurations of the Ultrasonic Blower
Pack and humidifier. Learn how to install the unit in "Installation " on page23.

1. Ultrasonic Blower Pack
2. Flexible tubes
3. Electrical disconnect
4. Air gap funnel (for drain line)
5. Trap
6. Expansion tank (optional)
7. R.O. system
Note: The drain line should have a minimum internal diameter of 22 mm (7/8 in), with a constant
downslope (minimum 1.2°) to the air gap funnel, and must not touch the sides or bottom of the funnel.
Use stainless steel or plastic pipe if using D.I. or R.O.water.
Note: Flexible tubes should be as short as possible – the maximum length varies depending on the
humidifier capacity and material used (refer to "Model Designation" on page12). The flexible tube must

have a constant slope (minimum incline of 10° or minimum decline of 2°), and have no restrictions in
the line, and be no longer than 2 m in equivalent length (ex. bends in the tubing affect the equivalent
length).
Note: Flexible tubes must not merge. Merging multiple tubes to supply an individual blower pack will
lead to water droplets forming inside the mist channel and the risk of spitting out, wetting the floor in
front of the unit, any adjacent equipment, and walls. If a humidifier capacity higher than 9 kg/h (19.8
lb/h) is needed, use a separate Ultrasonic Blower Pack (one for each 9 kg/h (19.8 lb/h) required).
7.2 Location Requirements
The installation of the Ultrasonic Blower Pack depends largely on the location of the Ultrasonic Humid-
ifier.
For medium size Ultrasonic Humidifiers, the Ultrasonic Blower Pack may be mounted directly on the
unit, or it may be installed remotely. For large size Ultrasonic Humidifiers, the Ultrasonic Blower Pack
may only be installed remotely and connected by flexible tubes. To reduce condensate losses in remote
installations, Condair recommends installing the Ultrasonic Blower Pack as close to the humidifier as
possible. Distances longer than an equivalent straight-length of 2 m (6.6 ft) reduces the mist output
drastically. Refer to "Mounting Requirements" on page22.
Refer to the Ultrasonic Humidifier Installation Manual (P/N: 2588786_A_EN_1811_US_IM).
The clearance requirements ensure that mist does not come into contact with any surfaces before it is
absorbed into the air. Refer to "Clearance Requirements" below.
IMPORTANT! For installations where the humidified space is separate from the humidifier, ensure that
there is adequate air flow to the humidifier, and adequate air flow out of the space to be humidified,
such that the atmospheric pressure in these spaces are equal. For example, if the humidifier is in a
separate room from the Ultrasonic Blower Pack, provide air from the humidified space to the air intake
of the humidifier.
7.3 Clearance Requirements
The clearances for the Ultrasonic Blower Pack in Figure 6 - on the next page and in Table 5 on the next
page are shown for reference only, and are the minimums required for the proper functioning of the
equipment. Consult local and national installation codes. Condair does not accept responsibility for viol-
ations of installation codes.
Adjacent Ultrasonic Blower Pack units should be separated by distance, D. For clearance requirements
for the Ultrasonic Humidifier, consult the Ultrasonic Humidifier Installation Manual (P/N:2588786_A_
