SAFETY REQUIREMENTS
While operating and mounting the unit consider the requirements of the present operation manual as well as general requirements of
all applicable local and national building and electrical codes and standards.
The unit must be grounded!
Before connecting the unit to power mains make sure that the unit is free of any visible damages or any other foreign objects inside the
casing that can damage the impeller blades.
WARNING!
DISCONNECT THE UNIT FROM POWER SUPPLY PRIOR TO ANY MOUNTING,
SERVICING, CONNECTION OR REPAIR OPERATIONS WITH THE UNIT.

RESTRICTIONS!
• DO NOT OPERATE THE UNIT BEYOND THE SPECIFIED TEMPERATURE
RANGE OR IN AN AGGRESSIVE AND EXPLOSIVE MEDIUM!
• DO NOT CONNECT CLOTHES DRYERS OR SIMILAR EQUIPMENT TO THE
VENTILATION SYSTEM!
• DO NOT OPERATE THE UNIT IN THE AIR AND DUST MIXTURE MEDIUM!
STRUCTURE AND OPERATING LOGIC
The unit operating principle is as follows (fig. 2). Warm stale air from the premises extracted by the unit is purified in the extract filter,
then it passes through the heat exchanger and then is exhausted outside through the ducts by the exhaust fan.
Clean cold intake air supplied to the unit is purified in the supply filter. The air passes through the heat exchanger and then fed into
the premises by the supply fan. Thermal energy of warm extract air is transferred to clean intake fresh air from outside and warms it up.
The air flows are fully separated. Heat recovery minimizes thermal energy losses, energy demand and operating costs for heating during
winter time.
The unit is equipped with a posistor 350 W electric heater to enable supply air warming up. The heater has overheating protection.

MOUNTING AND SET-UP
Mount the unit to provide enough access for maintenance or repair operations.
The wall for mounting must have even surface. Any surface irregularities will lead to unit casing skew and may prevent the unit from
operating properly. The minimum distances from the unit to the mounting surfaces are shown in fig. 3.
min 300 mm
min 300 mm
Fig. 3. Minimum distance from the unit to the surfaces
The unit is designed for installation directly in the premise to be ventilated. Prior to starting mounting operations mark and bore holes
in the wall with the master plate, fig. 4.
Mounting sequence with the master plate, fig. 5:
1. Fix the master plate on the wall with a self-adhesive tape at required level.
2. Indicate two marks for two holes Ø130 mm for air ducts and four holes Ø 8 mm for the unit fasteners.
3. Take off the master plate and drill through holes for the air ducts and holes, 90 mm deep for the unit fasteners. Insert the dowels,
remove the perforated fillers for the air ducts from the master plate and re-install the master plate back using a self-adhesive tape.
4. Insert the air ducts into the respective openings in the master plate.
5. Fill the spaces between the air ducts and the wall with a mounting foam through the specially designed holes in the master plate.
Wait till a mounting foam hardens (solidification time depends on the foam mark), take off the master plate and remove the foam excess.
Cut off the protruding air duct parts to be flush with the wall surface.
6. Insert the unit spigots to the air ducts.
7. Open the access door in the unit and remove the heat exchanger.
8. Mount the unit to the wall with the countersunk head screws and 8x80 dowels (included into delivery set) into two Ø 8 mm holes.
9. Install the heat exchanger and close the access door.
10. Fix the outer ventilation box (not included into delivery set) or Ø 125 mm ventilation grille on the outer wall of the building.

CONNECTION TO POWER MAINS
DISCONNECT THE UNIT FROM THE POWER MAINS PRIOR TO ANY OPERATIONS.
THE UNIT MUST BE PLUGGED INTO A PROPERLY INSTALLED POWER SOCKET
WITH AN EARTHED TERMINAL.
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE SHOWN ON THE
RATING PLATE.
ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED AND
WILL VOID THE WARRANTY.
The unit is designed for connection to 230 V / 50 Hz single-phase AC mains.
The unit is supplied with a power cable and a plug. The unit must be connected to power mains through a grounded power socket
compliant with IEC 60884-1. The power cable is pre-wired to the terminal block X1 by the manufacturer, fig. 7.
Connect the unit to power mains through the external automatic circuit breaker integrated into the fixed wiring system. Install the
circuit breaker to have a free quick access in case of need to turn the unit off promptly.
The circuit breaker trip current must be in compliance with the current consumption. The recommended circuit breaker rated current
is 2.5 A. While selecting the automatic circuit breaker consider the maximum wire temperature that depends on the wire type, insulation,
length and layout way (open wire mounting, channel type or wall-mounted).

MAINTENANCE
The unit requires maintenance works 3-4 times per year. Maintenance includes regular cleaning and the following operations:
1. Filter maintenance (3-4 timed per year).
Dirty filters increase air resistance in the system and reduce supply air volume. The filters require cleaning as they get clogged, but at least
once in 3-4 months. Vacuum cleaning is allowed. Replace the filters as they get clogged following the second cleaning.
Contact your seller for new filters.
To remove the filters, follow the procedure in the fig. 16:
1. Open the unit access door.
2. Remove the supply air filter above the heat exchanger;
3. Remove the heat exchanger from the unit by pulling its band;
4. Press the clamp and remove it;
5. Remove the extract air filter.
Install the filter in the reverse order.

4.
3.
5.
Fig. 16. Filter maintenance
2. Heat exchanger inspection (once per year).
Some dust can get accumulated on the heat exchanger block even in case of regular maintenance of the filters. To maintain the high
heat exchange efficiency, regular cleaning is required. To clean the heat exchanger pull it out of the unit and flush it with warm soap or mild
detergent water solution. Re-install the dry heat exchanger to the unit.
3. Fan inspection (once per year).
Even in case of regular filter and heat exchanger maintenance, some dust and grease can get accumulated inside the fans and reduce
the fan performance and supply air flow.
Clean the fans with a soft cloth or brush. No water and abrasive detergent, sharp objects or solvents are allowed for cleaning to prevent
the impeller damage.
15
4. Condensate removal (as required).
The drain pipes may get filled with condensate during cold season. As the drain pan gets filled with condensate, the unit is turned on
and the control panel displays the indicator to remind about the need to remove the condensate.
To remove condensate:
1. Disconnect the unit from power mains.
2. Open the unit door.
3.
Lift the condensate level switch.
4. Keep the condensate level switch, pull and remove the condensate drain pan carefully (Fig. 17).
Fig. 17. Drain pan removing
5. Empty the drain pan, lift the condensate level switch and re-install it back (Fig. 18).
Fig. 18. Drain pan installation
5. Supply air flow control (twice per year).
Leaves and other pollutions can clog the supply air grille and reduce the unit performance and supply air volume. Check the supply grille
twice per year and clean it as required.
6. Ductworks inspection (once in 5 years).
Even if you follow all the listed maintenance guidelines, some dust can get accumulated inside the air ducts and reduce the unit
performance. Duct maintenance means their regular cleaning or replacements.
