CHAPTER 1
GENERAL INSTALLATION AND OPERATING INSTRIUCTIONS
1.0 Important information
To ensure safety and correct operation please read and observe the following instructions carefully before proceeding.
Important information is specified in the maintenance section on filter changes and necessary cleaning and maintenance
activities. The user usually carries out maintenance work. The chapter “Installation” with important installation
tips and basic unit adjustments is intended for the specialised installer.
The electrical connection must be fully isolated from the supply up to the finalassembly!
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities,
or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by
a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
The planning office provides the planning documents necessary for system calculations. Additional information can be
requested ex works. Keep the installation and operating instructions as a reference at the device. After the final assembly,
the document must be handed out to the operator (tenant/owner).
1.1 Warning and safety instructions
The adjacent symbol is a safety-relevant prominent warning symbol. All safety regulations and/or symbols must
be absolutely adhered to, so that any dangerous situation is avoided.
1.2 Warranty claims –Exclusion of liability
If the preceding instructions are not observed, all warranty claims and accommodation treatment are excluded. This
also applies to any liability claims extended to the manufacturer.
The use of accessories not offered or recommended by AERA is not permitted. Potential damages are not covered by
warranty.
1.3 Regulations –Guidelines
If the product is installed correctly and used to its intended purpose, it conforms to all applicable CE standards
at its date of manufacture. The AERA AZURE WHEEL ventilation units in this series are compliant with Eco-Design 2018.
1.4 Storage
When storing for a prolonged time the following steps are to be taken to avoid damaging influences:
Protection by dry, air- dustproof packing. The storage place must be water protected, vibration-free and free of temperature
variations. (Ambient temperature limit, min/max, 0°C/ +40°C) Damages due to improper transportation, storage or putting into
operation are not covered by warranty.
1.5 Transport
The unit is packed ex works in a timber frame so that it is protected against normal transport strain. Carry out the shipping
carefully. It is recommended to leave the unit in the original packaging until installation to avoid possible damages
and soiling.
The transport must be carried out by trained and experienced personnel and the necessary safety precautions should be taken
to prevent overturning and slipping of the device. During transport of the devices it should be ensured that the weight is evenly
distributed over the four corners.
Danger due to overhead loads –risk of grave injuries ordeath!
- Never stand beneath suspended loads, since there is always a risk that the lifting gear, tackle, ropes or slings are faulty or
damaged.

4
- Make sure that equipment is firmly seated before liftingit.
Risk of injury! Watch out for nails when disassembling the timber frame!
Warning! Risk of personal injury and equipment damage!
Due to a high center of gravity, some equipment can tend to tip over and cause damage to persons and property.
- When transporting the unit, carefully observe its behavior and do not get near any possible hazardousareas.
1.6 Intended use
AZURE WHEEL 25 device is designed to correspond the need of 2500 m3/ h air flow. There is a ePM1 55% class filter on the
fresh air side and a ePM10 50% class filter on the exhaust side as standard. The units are produced according to European Union
energy criteria.
AZURE WHEEL devices are designed with high energy efficient, low sound pressure and low power consumption plug fans. Plug
fans with EC motors can be driven with 3 fixed speeds or steplessly with the help of an air quality sensor thanks to build in smart
control system.
The AZURE WHEEL units are equipped with rotary heat exchangers. Through this procedure more than 80 % of the extract air
heat is transferred to the external air. The supply air is led by the duct system to the primary (supply air needing) areas. The used
air is extracted from the secondary areas (like e.g. social rooms, toilets, showers etc.). It flows back through the ducting to the
ventilation unit, transfers the heat and is discharged by the exhaust air duct to theatmosphere.
The heat recovery efficiency depends on several factors, which include, among other things, air humidity and the temperature
variation of outside air and exhaust air. The fan performance can be adjusted by the controller in scope of delivery. Various
sensors e.g. CO2 or humidity sensors (accessory) are available on request, with which automatic fan control is possible.
Permissible operating air temperature and humidity is 0/40 °C and 95% RH for AZURE WHEEL units.
1.7 Performance data
Mechanical connections must be made correctly in order to obtain maximum efficiency from the device. The device's thermal
efficiency, sound level and electrical performance may vary depending on the ambient conditions the device is operating. These
conditions may affect the measurement result on site and vary from the catalogue data.
1.8 Guideline series VDI 6022
The AERA AZURE WHEEL ventilation units in this series are produced compliant with VDI 6022. The guidelines range from
operating regulations and material requirements through to construction regulations, which ensure high air quality. It must be
ensured that only original AERA accessories are used for operation compliant with VDI 6022.
1.9 Heat systems
The simultaneous use of controlled ventilation (AZURE WHEEL) and heat systems which depend on room air (tile oven, gas stove
etc.) requires compliance with all applicable regulations.
The use of heat systems which depend on room air are only permitted in state-of-the-art dense apartments with separate
combustion air supply; only then are AZURE WHEEL and heat systems decoupled from each other and operable meeting the
demands.
The relevant applicable regulations on the combined use of heat systems, domestic ventilation and extractor hoods (Federal
Association of Chimney Sweeps (ZIV)) must be observed!

1.11 Disassembly and re-assembly
Before starting any disassembly or re-assembly operation, please ensure that the product is
isolated from its mains electrical supply, in order to ensure that fans cannot be run. As disassembly and re-assembly
are not part of routine maintenance, these should be carried out by qualified personnel.
Ensure the unit is voltage-free andisolated, earth andshort circuit the unit, cover orshield off neighbouring live components.
Ensure that the hydraulic circuit is switched off.
Close all hydraulic shut-off valves.
Isolate all connections and ensure leak-free condition regarding oil, refrigerant
As the coil piping diameter is small, waste water can remain in the unit following normal evacuation. For safety reasons, use
compressed air to blow through the system in order to remove all remaining water.
Risk of personal injury and equipment damage!
Due to a high center of gravity, some equipment can tend to tip over and cause damage to persons and property.
When transporting the unit, carefully observe its behaviour and do not get near any possible hazardous areas.
1.12 Disposal
Before starting any operation, please ensure that the product is isolated from its mains electrical
supply, in order to ensure that fans cannot be run.
Dispose of all components and filters and disused operating materials (e.g. oil, refrigerants) in an environmentally-friendly
manner in accordance with the local codes, practices and environmental regulations.
An authorized appointed contractor specializing in waste processing must dispose of the unit or its individual components. This
appointed contractor must ensure that:
–the components are separated according to materialtypes
–the used operating materials are sorted and separated according to their respectiveproperties.
