- Make sure that equipment is firmly seated before lifting it.
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 hazardous areas.
1.7 Intended use
EVO-R devices are designed in 9 different models to correspond the need of up to 15000 m3/ h air flow. There is an ePM1 55%
class filter on the outdoor air side and an ePM10 50% class filter on the exhaust side as standard. The units are produced
according to European Union energy criteria and have EcoDesign label.
EVO-R devices are designed with energy efficient, low sound pressure radiating 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 EVO-R units are equipped with rotary heat exchanger. More than 80 % of the extract air heat is transferred to the outdoor 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 the atmosphere.
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
If the device is used at < + 5 °C, it is necessary to use a heater in the device electronic box. (not included scope of delivery,
optional)
The standard equipment permits the installation and the application in frost-free rooms > + 5 °C.
If the unit is to be used in outdoor, it is necessary to use a weather roof and outdoor spigot. (not included scope of delivery,
optional)
If the unit is to be used in other applications where high humidity, excessive dust, temperature in excess of 40 °C or long periods
at standstill (not running), please contact AERA sales representative. This also applies for special technical and electrical
applications.
The EVO-R units are equipped with an electrical pre-heater (accessory- not included in scope of delivery); this prevents the heat
exchanger from freezing at extremely cold outdoor temperatures.
Electrical after heater (accessory) used in EVO-R devices can be installed in the unit (EVO-15R, EVO-20R, EVO-30R) and module
(EVO-50R, EVO-60R, EVO-80R, EVO-95R, EVO-120, EVO-150R). The after heater is controlled by the desired supply air
temperature. The temperature is chosen by the user.
Water after heater (accessory) are used for increasing the supply air temperature and for bringing the supply air to the desired
temperature. Hot water coils can be driven by proportional control via 2 or 3-way valves. Frost protection mechanism is available
as standard to prevent the temperature of the supply water from reaching freezing conditions in extreme cold climates.
Externally module water cooling coils and DX coils (accessory) are used for such purposes as lowering the blowing temperature
and dehumidifying the air in the units. It can be driven either proportionally or by on / off method.

1.8 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.
1.9 Guideline series VDI 6022
The AERA EVO-R 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.
1.10 Heat systems
The relevant applicable regulations on the combined use of heat systems, domestic ventilation and extractor hoods (Federal
Association of Chimney Sweeps (ZIV) information) must be observed!
General construction-law requirements
The EVO-R units with heat recovery must only be installed and operated in rooms with heat systems which depend on room air,
if their flue gas venting is monitored by specific (on-site) safety devices, which shut down the EVO-R unit when activated. We
recommend speaking with the competent chimney sweep to take account of possible wishes before procuring a negative pressure
monitoring system for heat systems.

CHAPTER 2
INSTALLATION
2.0 Assembly
EVO-R compact devices must be mounted in a vertical position. Due to noise level which change according to working conditions,
it is recommended to install the EVO-R units in the infrequently used rooms like that storage rooms, washing rooms etc. If the
device to be used has a cooling coil, ensure that there is a waste water connection in the installation area. Assembly should take
place in such a way to enable preferably short ventilation ducts and their trouble-free connection to the unit. Tight bends can lead
to increased pressure loss and flow noise. The unit can be turned 180° for optimal installation, so that the outdoor/exhaust air and
extract/supply air inlets and outlets can be on the left or right side. There is no need for bends and long stretches of pipeline due
to these features. They reduce losses and increase the degree of efficiency of the system.
Important notes:
1. The ventilation ducts must not become kinked.
2. Any kind of connections (valves, flanges etc.) which associated with fluids like that air or water, must be tight and leakproof.
3. If necessary, vibration isolators can be used between unit and floor.
4. In order to prevents sound transmission, appropriate acoustic decoupling must be provided on site depending on the building
material.
The outdoor spigot should be placed on the exhaust air side in case of no duct connection.
Make sure that the device is placed on a flat surface before any assembly work.
Assembly area
Observe the following criteria during installation to ensure that the device service is comfortable. (Fig. 1)
A is the minimum distance for servicing the terminal box.
C is the minimum distance for opening service cover.

2.1 Unit insulation
The outside and exhaust air ductwork should be insulated sufficiently.
If the unit is to be used in outdoor, make sure that the necessary equipment is installed. (weather roof and outdoor spigot, optional)
2.2 Installation
EVO-R has easily adjustable stays. (Fig. 2) First of all, make sure that there is enough space for the device servicing. Therefore,
the device must be assembled after the dimensions have been identified.
Make sure that the device is placed on a flat surface before any assembly work.

2.5 Air ducting, Ventilation circuit
When designing the ductwork, use the shortest possible runs. Airtight connections and changeovers must be ensured for the best
possible heat recovery. To avoid pressure losses, dirt build-up and noise, use smooth ducts (plastic or rigid ducting). If supply and
extract air ductworks run through unheated rooms, insulation must be provided to reduce heat losses. Fresh air should be supplied
to living and bedrooms and extraction should take place in bathrooms, toilets and kitchens. The installation of extractor hoods to
the system is not permitted (reasons: dirt, fire danger, hygiene).
All fire and building regulations must be observed!
2.6 Electrical Connection
The unit must be fully isolated from the mains power supply before any maintenance and
installation work or before opening the enclosure! The electrical connection must only be carried out by an authorised
qualified electrician in accordance with the following wiring diagrams. The electrical connection must be fully isolated
from the mains power supply until the assembly is complete!
The unit is equipped with a main switch and an isolator which can be secured against unauthorized switching with a U-lock. The
relevant standards, safety regulations (e.g. DIN VDE 0100) and the technical connection conditions of the local electricity supply
companies must be observed. An all-pole mains switch / isolator, with a contact opening of at least 3 mm (VDE 0700 T1 7.12.2 /
EN 60335-1) must be provided. The main switch and/or isolator can be secured against unauthorized switching with a U-lock.
The surface-mounted controller with touchscreen is connected to the unit by means of a 5 m connecting cable (also available in
10 or 20 m length). The electrical connection of the EVO-R takes place directly in the terminal box. If any electronic accessory is
added the unit, the electrical connections must be made in the terminal box.

SERVICE AND MAINTENANCE
5.0 Service and maintenance
The filter change is usually carried out by the user. Additional cleaning and maintenance work must only be carried out
by qualified electricians.
The EVO-R unit must be fully isolated from the power supply and secured against reactivation with the main
isolator switch located on top of the unit before any cleaning and maintenance work.
Danger of electric shock, moving parts (fan) and hot surfaces.
5.1 Service and maintenance of rotary heat exchanger
Make sure that the power connection is disconnected before doing any work on the device. Danger of electric
shock; moving parts (fan) and hot surfaces.
Maintenance is restricted to regular visual inspections. Inspections should be initially carried out about every 3 months and then
after trouble-free operation can be extended to 12 months. The following must be checked:
- Tension of drive belt
- Quality of bearings (assess by bearing noise)
- Function of slide seal
- Condition of casing
RISK OF INJURY! High weight! Two people are required for dismantling! (EVO-15R, EVO-20R)
Use forklift to transport the heat exchanger on the EVO-30R, EVO-50R, EVO-60R, EVO-80R, EVO-95R, EVO-120R,
EVO-150R models
