PURPOSE

The unit is designed to ensure continuous mechanical air exchange in houses, offices, hotels, cafes, conference halls, and other utility and public spaces as well as to recover the heat energy contained in the air extracted from the premises to warm up the filtered stream of intake air.
The unit is not intended for organizing ventilation in swimming pools, saunas, greenhouses, summer gardens, and other spaces with high humidity.
Due to the ability to save heating energy by means of energy recovery, the unit is an important element of energy-efficient premises.
The unit is a component part and is not designed for stand-alone operation. It is rated for continuous operation.
Transported air must not contain any flammable or explosive mixtures, evaporation of chemicals, sticky substances, fibrous materials, coarse dust, soot and oil particles or environments favourable for the formation of hazardous substances (toxic substances, dust, pathogenic germs).
THE UNIT SHOULD NOT BE OPERATED BY CHILDREN OR PERSONS WITH REDUCED PHYSICAL, MENTAL, OR SENSORY CAPACITIES, OR THOSE WITHOUT THE APPROPRIATE TRAINING.
warning 2 THE UNIT MUST BE INSTALLED AND CONNECTED ONLY BY PROPERLY QUALIFIED PERSONNEL AFTER THE APPROPRIATE BRIEFING.
THE CHOICE OF UNIT INSTALLATION LOCATION MUST PREVENT UNAUTHORIZED ACCESS BY UNATTENDED CHILDREN.

BLAUBERG KOMFORT Ultra L 250-H Heat Recovery Air Handling Unit - DESIGNATION KEY

TECHNICAL DATA

The unit is designed for application with the ambient temperature ranging from +1 °C to +40 °C and relative humidity up to 80 %.
In order to prevent condensation on the internal walls of the unit, it is necessary that the surface temperature of the casing is 2-3 °C above the dew point temperature of the transported air.
The unit is rated as a Class I electrical appliance.
Hazardous parts access and water ingress protection rating:

  • IP22 for the unit connected to the air ducts;
  • IP44 for the unit motors.

The unit design is constantly being improved, thus some models may be slightly different from those described in this manual.

DESIGN AND OPERATING LOGIC

Warm stale extract air from the room flows into 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.
Clean cold air from outside is moved to the supply filter. Then filtered air flows through the heat exchanger and is moved to the room with the supply fan. Heat energy of warm extract air is transferred to clean intake fresh air from outside and warms it up.
Heat recovery minimizes thermal energy losses and space heating expenses in cold seasons.
BLAUBERG KOMFORT Ultra L 250-H Heat Recovery Air Handling Unit - DESIGN AND OPERATING LOGIC

Freeze protection
The heat exchanger freeze protection function of the unit is implemented with a temperature sensor or a thermostat depending on model. The temperature sensor is installed in the exhaust air duct downstream of the heat exchanger. In case of a freezing danger (extract air temperature downstream of the heat exchanger is +3 °C) the supply fan is turned off and the heat exchanger is warmed up with warm extract air flow. To set the thermostat temperature set point set the temperature control knob into a respective position.BLAUBERG KOMFORT Ultra L 250-H Heat Recovery Air Handling Unit - Freeze protection

INSTALLATION AND SET-UP

warning 2 READ THE USER’S MANUAL BEFORE INSTALLING THE UNIT.
warning 2 THE UNIT MUST BE MOUNTED BY A QUALIFIED EXPERT ONLY, PROPERLY TRAINED AND HAVING THE REQUIRED TOOLS AND MATERIALS.
While installing the unit, provide enough access for maintenance or repair work.
When selecting an installation location of the unit, provide free opening of the service panel.
To get the best performance of the unit and to minimize turbulence-induced air pressure losses, connect the straight air duct section to the spigots on both sides of the unit while installing.
Minimum straight air duct length:

  • equal to 1 air duct diameter on intake side
  • equal to 3 air duct diameters on outlet side

If the air ducts are too short or not connected, protect the unit parts from ingress of foreign objects.
To prevent uncontrollable access to the fans, the spigots may be covered with a protecting grille or other protecting device with mesh width not more than 12.5 mm.
The unit must be mounted on a plane wall.
Installing the unit to an uneven surface could lead to the unit’s casing distortion and operation disturbance.
The unit is designed for mounting on a horizontal plane as well as for wall mounting with a fixing bracket that is fastened with three screws and dowels (not included in the delivery set).

TECHNICAL MAINTENANCE

warning 2 DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS.
FOLLOW THE SAFETY REGULATIONS WHEN CARRYING OUT MAINTENANCE.
Maintenance operations of the unit are required 3-4 times per year. It 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. The filters require cleaning not less than 3-4 times per year.
    Vacuum cleaning is allowed. After two consecutive cleanings filters must be replaced. For new filters contact the Seller. The steps to replace the filters are as follows (refer to the figure on p. 14):
    1. Press out on the latches.
    2. Open the unit panel.
    3. Remove the filters from the unit.
  2. Fan maintenance (once per 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 fans with a soft brush or cloth. Do not use water, aggressive solvents, or sharp objects as they may damage the impeller.
  3. Heat exchanger maintenance (once per year).
    Some dust may accumulate on the heat exchanger even in case of regular maintenance of the filters. To maintain the high heat recovery efficiency, regular cleaning is required. To clean the heat exchanger, pull it out, flush the heat exchanger with warm  detergent solution.
    After cleaning install the dry heat exchanger back to the unit.
    To remove the filters and the heat exchanger follow the operation operation in Fig. 16:
    1. Release the latches and remove the bottom panel.
    2. Open the unit panel.
    3. Remove the heat exchanger.
  4. Technical maintenance of condensate drainage system (once a year).
    The condensate drainage (drain line) may get clogged by dirt and dust particles contained in the exhaust air. Check the drain line operation by filling the drain pan under the unit with water, clean the U-trap and the drain line, if necessary.
  5. Supply air flow control (twice per year).
    The supply duct grille may get clogged with leaves and other objects reducing the unit performance and supply air delivery. Check the supply grille twice per year and clean it as required.
  6. 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.
