UNIT 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. The thermal energy of warm extract air is transferred to a clean intake of 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.

• The Freshbox E-100 K1 units are equipped with a supply air preheater with automatic overheating protection. The preheater is located upstream of the heat exchanger and is designed for its freeze protection. When the intake air temperature is below -3 °C, the preheater automatically warms up the 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 automatically by the temperature sensor.

• The heat exchanger freeze protection in the Freshbox 100 K1 models without a preheater is achieved by automatic supply fan speed reduction according to extracted air sensor readings. The extract fan runs at maximum speed.

• Temperature differences between supply and extract air flows in the 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 the units equipped with an enthalpy heat exchanger as moisture is transferred from one air flow to another through the membrane.

• The louver shutters open automatically when the motors are switched on and close when the motors are switched off.

• An additional outlet spigot can be fitted to the unit to connect the exhaust air duct from additional premises, e.g. a bathroom.

INSTALLATION AND SET-UP

• READ THE USER’S MANUAL BEFORE INSTALLING THE UNIT
• WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT MAINTENANCE AND REPAIR.

TECHNICAL MAINTENANCE

• DISCONNECT THE UNIT FROM THE POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS!
• MAKE SURE THE UNIT IS DISCONNECTED FROM THE POWER MAINS BEFORE REMOVING THE PROTECTION.

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 the 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.

3. Fan maintenance (once a year).
   Even in the 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.

4. 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’s performance. Check the supply grille twice per year and clean it as required.

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