DESIGNATION KEY

TECHNICAL DATA

The temperature in the room where the indoor unit of the ventilator is installed must be in the range from +1 ˚C to +40 ˚C with relative humidity up to 65 % (no condensation build-up). If the conditions for using the ventilator are beyond the specified limits, turn off the ventilator. Provide fresh air supply through windows.
The transported air temperature must be in the range from -20 ˚C to +40 ˚C.
The unit is rated as a class II electric appliance.
Ingress protection rating against access to hazardous parts and water ingress is IP24.
The unit design is constantly being improved, thus some models may be slightly different from those described in this manual.
Technical specifications of the particular model are indicated on the unit casing.The air duct length depends on the unit model, refer to the Designation Key section, page 4.

DESIGN AND OPERATING PRINCIPLE

The ventilator consists of an indoor unit with a decorative front panel, a cartridge, an air duct with a sound absorbing layer and an outer ventilation hood.
The cartridge is a basic functioning part of the ventilator. The cartridge consists of a fan, a regenerator and two filters that ensure rough air filtration and prevent ingress of dust and foreign objects into the regenerator and the fan.
The indoor unit is equipped with a manually actuated air damper.
WARNING! Air damper closing does not turn off the ventilator, but only blocks the air flow.
The external protective grille or the ventilation hood on the outer wall prevents ingress of water and foreign objects into the ventilator. VENTILATOR OPERATION MODES
The ventilator has two operation modes:
Ventilation: the ventilator runs either in extract or supply mode at a set speed.
In this mode, when two ventilators are installed, one of them supplies and the other one extracts the air.
Regeneration: the ventilator runs in two cycles, 70 seconds each, with heat and humidity regeneration.

• Cycle I. Warm stale air is extracted from the room and flows through the ceramic regenerator, which gradually absorbs heat and humidity. In 70 seconds, as the ceramic regenerator gets warmed, the ventilator is switched to supply mode.
• Cycle II. Fresh intake air from outside flows through the ceramic regenerator, absorbs accumulated moisture and is heated up to the room temperature. In 70 seconds, as the ceramic regenerator gets cooled down, the ventilator is switched to air extract mode and the cycle is renewed. If two ventilators are installed, they operate with opposite rotation directions in this mode. While one ventilator supplies air, the other one extracts it.

MOUNTING AND SET-UP

READ THE USER’S MANUAL BEFORE INSTALLING THE UNIT.
WALL-MOUNTED CONTROL PANEL INSTALLATION
MAKE SURE THAT THE CONTROL PANEL IS NOT DAMAGED.
DO NOT USE A DAMAGED CONTROL PANEL! DO NOT INSTALL THE CONTROL PANEL ON AN UNEVEN SURFACE! WHILE TIGHTENING THE SCREWS, DO NOT APPLY EXCESSIVE FORCE TO PREVENT THE CONTROL PANEL CASING DEFORMATION.

Control panel mounting:

1. Prepare a hole in the wall and route all the wires to the installation place. Insert the supplied mounting box for flush wall mounting. The mounting box is included in the  delivery set.

2. Use a screwdriver to carefully undo the clips on the backside of the control panel and remove the back cover.

3. Screw the backside of the casing to the mounting box through the fastening holes. Fastening screws for control panel mounting are included in the control panel delivery set. Then connect the cable to the control panel in compliance with external wiring diagram.

4. Install the control panel display and press it to fix.

VENTILATOR MOUNTING
READ THE USER’S MANUAL BEFORE INSTALLING THE UNIT.
DO NOT BLOCK THE AIR DUCT OF THE INSTALLED UNIT WITH DUST ACCUMULATING MATERIALS, SUCH AS CURTAINS, CLOTH SHUTTERS,  ETC. AS IT PREVENTS AIR CIRCULATION IN THE ROOM.

1. Prepare holes for the air ducts.
   Prepare one or two round core holes in the outer wall, depending on the ventilation system equipment. For efficient operation of the ventilation system it is recommended to install the ventilators as far apart from one another as possible. While preparing a core hole make preparations for layout of the power cable and other required cables. The core hole size and minimum distance to a mounting surface, for example, a wall, ceiling or a window as well as the minimum distance between the ventilators are shown below.
   

2. Prepare air ducts of required length.
   Measure the wall thickness B.
   The air duct length is calculated as L = B + A, where A means an air duct segment that protrudes in the outer wall to enable installation of the external grille or the outer ventilation hood.
   Distance A is stated in the installation instruction for the ventilation hood.
   Cut the air duct to the length L

3. Insert the sound-absorbing layer in the air duct.
   Prior to installation adjust its length with respect to the dimensions of the cartridge, the indoor unit, and the outer hood.
   Insert the cartridge during adjustment in the air duct and cover it with the internal grille. Roll the sound-absorbing layer to match the air duct diameter with the protecting paper layer outside and insert the roll in the air duct against stop.
   Do not remove the paper layer!
   Ventilator with an internal grille
   Mark the sound-absorbing layer at the end of the air duct as 1. From the mark 1 measure 50 mm (2’’) and make the mark 2. Cut the excessive part of the sound-absorbing layer.
   Insert the adjusted and ready sound-absorbing layer into the air duct.
   No glue is required for fixation!
   Ventilator with an outer hood (option).
   Mark the sound-absorbing layer at the end of the air duct as 1. Cut the excessive part of the sound-absorbing layer.
   Insert the adjusted and ready sound-absorbing layer into the air duct.
   No glue is required for fixation!

4. Insert the air duct in the wall.
   Install the air duct with the minimum slope 3 mm downwards. Fill the gaps between the wall and the hole with a mounting foam.

5. Secure the back part of the indoor unit by leading the cable through the hole. Insert the cartridge into the air duct. Disconnect the connector on the cartridge wire and connect the wires (laid from the control panel in accordance with the diagram on page 12) to the mating part. Connect the parts of the terminal block.
   

6. Install the front panel of the indoor unit and fasten the outer ventilation hood.
   For mounting of the outer ventilation hood, please refer to a respective hood installation instruction.

CONNECTION TO POWER MAINS

POWER OFF THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT.
THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN.
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE MANUFACTURER’S LABEL.
ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED AND WILL VOID THE WARRANTY.
The ventilator is rated for connection to single-phase AC 100-240 V 50/60 Hz power mains.
The ventilator is connected to power mains using insulated, durable and heat- resistant conductors (cables, wires) with a cross section of at least 0.5-0.75 mm2 through the automatic circuit breaker with a magnetic trip built into the stationary wiring. The circuit breaker trip current must be selected depending on the ventilator current consumption. For details, please refer to the table on page 5.
The actual conductor cross-section selection must be based on its type, maximum permissible heating,  insulation, length and installation method.
When choosing a signal cable, follow these guidelines:

• Always use a shielded cable.
• The cross-section of the conductors, depending on the length, is selected according to the table below.
  Cable length [m]| The minimum cross-section of the wires in the cable [mm²]
  ---|---
  < 5| 0.25
  < 10| 0.5
  < 15| 0.75
  < 30| 1.5
• Lay a signal cable in compliance with the requirements of the relevant regulatory documents.
• Connect the signal cable shield to the terminals „-“ of the control panel and the fan. Use copper wires for all the electric connections!
• Connect the ventilator to power mains in compliance with the wiring diagram.
