Installation – step 1
ACA Dist. panel positioning &
mounting
General guidelines for positioning
ACA in space distribuon panel should be posioned so that:
Unintenonal weng cannot occur on equipment, material or building surface or
people. A ceiling height of 9 [2.7m] minimum is recommended.
Humidifier is easily accessible for service
CAUTION. Risk of flooding. Ensure that the space where ACA Compressed air &
water atomizing humidifier will be installed is equipped with floor drain.
In case of no floor drain is available; installaon of a water leak detector is required
in order to prevent any flooding in case of abnormal operaon or service.
ACA Compressed air & water atomizing humidifier should be installed in a well-venlated and
dry environment.
If local is subject to below freezing point temperature, an freezing disposion such as heat
trace on any water carrying device and pipe is required.

I N S T A L L A T I O N
Clearance guidelines
There is no minimum clearance on both side of the ACA distribuon panel, but it is a good
pracce to have a clearance of 4 to 8 in [100 to 200mm] for ease of installaon and service
Allow a minimum clearance of 24in [60cm] with ceiling.
Front clearance of 8-1/2 [2.5m] in front of nozzle is required to avoid any unintenonal
weng on surfaces, equipment, wall, or people.
It is a good pracce to install ACA in space distribuon panel where ceiling height is 9
[2.7m]minimum
Mounting holes positions
Figure 5 – ACA distribuon panel mounng holes posion
General guidelines for Mounting
CAUTION. Risk of malfuncon. ACA distribuon panel must be levelled in X & Z axis.
Installaon on wall
1. Verify that wall structure and strength is appropriate to support the weight of the
ACA distribuon panel.
2. Mark the wall or support according to the holes locaon as per the above figure , and
drill 4 holes to the wall or support as per the size of anchors and/or screws.
3. Use anchors of sufficient size (at least 1/4in [6mm]). Insert those anchors and the 2 top
screws. Then hung the ACA distribuon panel onto the 2 top screws.
Ensure that the humidifier is properly levelled.
4. Insert the 2 boom screws and ghten them up. Re verify the level in the 2 direcon X
and Z axis.
1. Tighten the 4 screws.

Water supply installation
Water supply specification& quality:
Water supply pressure: 40 to 60PSI [2.8 to 4bar] – hammer free
Water supply temperature: 37 to 68°F [3 to 20°C]
ACA Compressed air & water atomizing humidifier can accept a wide range of water quality.
Important: the use of untreated water will lead to fine parcles deposit with the atomized
water, resulng is fine powder deposit in surrounding surfaces or air filter.
ACA should be connected to a clean, wholesome mains water supply. Installer and user are
responsible to ensure that the water supply system complies with local regulaons in regards
to Legionella and any other microbiological growth prevenon,
A 1μm sediment filter and a silver ions anbacterial cartridge or UV sterilizer must be installed
on the water supply line.
Untreated water requirement Pure water requirement
Water supply conducvity: 1 to 156µS/cm

I N S T A L L A T I O N
Water supply connection:
1. Install a manual; shut off valve on the water main line.
2. If ACA distribuon panel is supplied with tap water it is recommended to install a 5µm
sediment filters on the line. This filter will protect internal water components from
clogging.
3. ACA atomizing humidifier is supplied with 2 stages filters 1µm & anbacterial silver
ions cartridge. Install this pre-filter on the water main line downstream of the manual
shut-off valve.
4. Connect water supply to the 3/8in compression fing connecon. located at the
boom of ACA distribuon panel and secure the water line.
5. Ensure that the water line is hammer free and leak free.
Important: In case ACA atomizing humidifier is Off for more than 24hours, user should be
able to isolate the water main supply line and drain the ACA water supply line in order to
avoid any stagnant water and associated risk of legionella growth.

Compressed air installation
Compressed air specification& quality:
Water supply pressure: 87 to 100PSI [6 to 7bar]
Air supply should be clean, dry and free from oil.
In case dirt or oil is contained in air supply, an air filter and oil separator should be installed.
Any oil collector should be connected to an oil drain.
To prevent bacterial growth, compressed air piping should be non-corrosive and any joinng
material should be inorganic.
Figure 7 Compressed air installaon
Compressed air connection:
6. Install a manual shut off valve on the compressed air line.
7. Install an air filter and oil separator on the line. This filter will protect ACA internal
component and avoid spraying oil in the air.
8. Connect compressed air to the universal quick coupling M type 1/4 connecon.
located at the boom of ACA distribuon panel and secure the compressed air line.
9. Ensure that the compressed air line is leak free.

ACA control panel should be posioned so that:
Unintenonal weng cannot occur the control panel
Control panel is easily accessible for set-up and control of the ACA distribuon panel
and atomizing
It is protected from sun and rain
Maximum length of cable to ACA distribuon panel and to RH% & Temp sensor is 30
