DESIGN AND OPERATING PRINCIPLE

• Warm stale extract air from the room flows to the unit, where it is filtered by the extract filter, then air flows through the heat exchanger and is exhausted outside by the extract fan.
• Cold fresh air from outside flows into the unit, where it is cleaned by the supply filter. Then filtered air flows through the heat exchanger and is moved to the room with 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 heat losses, which reduces the cost of space heating in the cold season.
• Depending on the model the unit is equipped with a supply air preheater or reheater with overheating protection.
• The Freshbox E-100 WiFi, Freshbox E2-100 WiFi units are equipped with a preheater.
• The preheater is located upstream of the heat exchanger and is designed for its freeze protection.
• The Freshbox E1-100 WiFi, Freshbox E2-100 WiFi units are equipped with a reheater.
• The reheater is located downstream of the heat exchanger and is designed for extra heating of supply air to more comfortable temperature. When the intake air temperature is below -3 °C, the preheater automatically warms up intake air so the average exhaust air temperature downstream of the heat exchanger is not below +5 °C.
• The reheater is switched on and off by means of a button on a sensor control panel, a remote control or via mobile application.
• The heat exchanger freeze protection in Freshbox 100 WiFi and Freshbox E1-100 WiFi unit models without a preheater is achieved by automatic supply fan speed reduction according to extract air sensor readings.
• The extract fan runs at maximum speed.
• Temperature differences between supply and extract air flows in units with polystyrene heat exchangers lead to condensate formation. Condensate is collected in the drain pan and is removed outside by the drain pipes through the exhaust air duct.
• Condensate is not formed in units equipped with an enthalpy heat exchanger as moisture is transferred from one air flow to another through a membrane.
• The louvre shutters open automatically when the motors are switched on and close when the motors are switched off.
• *An additional extract spigot can be fitted to the unit to connect the exhaust air duct from additional premises, e.g. a bathroom.
• The spigot is included in the delivery set.

   When mounting the unit with an additional extract spigot prepare a hole in the wall for a connecting bend and for laying of a rectangular air duct.
   A connecting bend, rectangular and round air ducts are available separately. Drill holes (Ø 8 mm, 90 mm deep) to mount the unit. Install the expansion anchors, remove the perforated fillers for the air ducts from the mounting template and install the mounting template back using self-adhesive tape .

3. Cut air ducts of the required length. Note that the telescopic air duct end must protrude for the distance that enables installation of the outer ventilation hood. For details, refer to the installation instruction for the ventilation hood.
   The outer ventilation hood is available separately.

4. Fix the mounting template on the wall to install the air ducts.
   Insert the air ducts in the corresponding holes of the mounting template.
   Install the air duct with a minimum slope of 3 mm for condensate removal.
   To install the unit with an additional spigot, insert the connecting bend into the prepared hole in the wall, aligning the mounting template hole with a round end of the connecting bend.
   Connect a rectangular duct to the connecting bend.

5. Fill the spaces between the air ducts and the wall with a mounting foam through the specially designed holes in the mounting template.
   Wait till the mounting foam hardens then take off the mounting template and remove the foam excess. Cut off the protruding air duct parts to be flush with the wall surface.

6. Fill the spaces between the air ducts and the wall with a mounting foam through the specially designed holes in the mounting template.
   Wait till the mounting foam hardens then take off the mounting template and remove the foam excess. Cut off the protruding air duct parts to be flush with the wall surface.

7. To install an additional extract spigot, remove the plug on the rear part of the unit.
   Undo the screws, remove the plug and fix a spigot on its place using screws .

8. Caution! Install the condensate preheater before fixing the unit to the wall (see the Installation manual of the heater).
   Insert the connecting cables of the heater, external humidity sensor or CO2 sensor into the control unit through the corresponding holes on the back wall of the unit.

   • Open the unit, undo the fixing screws and remove the heat exchanger.

   • Lift the unit and insert the spigots into the corresponding air ducts installed in the wall.
     Caution! Remove the magnetic plug from the exhaust grille if an additional extract spigot is not installed.

   • Fix the unit on the wall using the supplied screws and dowels.

   • Install the heat exchanger back to the unit.

   • Install the humidity or CO2 sensor (available separately) on the bracket.

   • Make electrical connections, see “Connection to power mains”.

   • Reassemble the unit in reverse order.

9. Install the outer ventilation hood:

   • Cut a part of the drain pipe protruding outside to a length not more than 10 mm.
   • Remove the foam excess.
   • Fill the gaps between the air ducts with sealant.
   • Fix the outer hood on the outer wall of the building (see the ventilation hood installation manual).

CONNECTION TO POWER MAINS

Warning: POWER OFF THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT. THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN.

TECHNICAL MAINTENANCE

Maintenance operations of the unit are required 3-4 times per year. Maintenance includes periodic dust removal from surfaces, cleaning and replacement of filters and dry cleaning of fans.
Maintenance includes general cleaning of the unit and the following operations:

1. Filter maintenance (3-4 times per year).
   • Dirty filters increase air resistance in the system and reduce supply air volume.
   • Remove the clogged filters from the unit.
   • Clean the F8 filter with a vacuum cleaner.
   • To remove the G4 filters for cleaning remove the flexible clamps fixing them and pull the filters until they slide off the guides. Clean the filters with water and let them dry. After complete drying reassemble the filters in the reverse order.
   • Install the filters back to the unit.
   • The filters require cleaning not less than 3-4 times per year.
   • For new filters contact the Seller.
2. Heat exchanger maintenance (once a year).
   • Some dust may accumulate on the heat exchanger block even in case of regular maintenance of the filters.
   • To maintain the high heat recovery efficiency, regular cleaning is required.
   • Periodical dry cleaning is recommended. Use a vacuum cleaner with a narrow nozzle.
   • Remove the clogged heat exchanger out of the unit, clean it with a vacuum cleaner and install the heat exchanger back to the unit.

Fan maintenance (once a year).
Even in case of regular maintenance of the filters, some dust may accumulate inside the fans and reduce the fan performance and supply air flow.
Clean the fan with a cloth or a soft brush.
Do not use water, aggressive solvents, or sharp objects as they may damage the impeller.

Technical maintenance of the supply grille (twice a year).
The supply grille may get clogged with leaves and other objects which may reduce the unit performance.
Check the supply grille twice per year and clean it as required.

Technical maintenance of air duct system (every 5 years).
Even regular fulfilling of all the prescribed above maintenance operations may not completely prevent dirt accumulation in the air ducts which reduces the unit capacity.
Duct maintenance means regular cleaning or replacement.

is properly connected to the power mains and make any corrections, if necessary.
