Recommendations for the installation area:
The heat recovery unit should be installed in an insulated area protected from frost to prevent the evacuated conde sates from
|
freezing.
The heat recovery unit should not be installed in very moist rooms like bathrooms..
|
The humidity of the installation area should be permanently lowered with sufficient ventilation.
|
To speed the evacuation of moisture in new buildings it is also necessary to ventilate the structure naturally before use.
|
To achieve a vibration free result, the heat recovery unit should be wall-mounted with minimum force of 200 kg/m² or be
|
placed on a mounting block on a surface with the same minimum force.
Recommendations for the roof/wall penetrations:
The roofs and walls should be completely insulated.
|
Recommendations for the air conduits:
The air conduits should be thermally insulated towards and from the outside. To avoid any risk of condensation, we recom-
|
mend that flexible insulated tubes should not be used.
The air conduits must be mounted airtight.
|
To reduce the overall noise level we recommend in the design reducing the pressure of the external conduit to 100 Pa in the de-
|
sign flow. In all cases the external pressure should be limited in practice to a maximum of 150 Pa.
The air speeds in the main conduit should be limited to 5 m/s maximum in the main channels and 3.5 m/s in the branches.
|
Recommendations for evacuating the condensates:
Ball siphon supplied standard.
|
According to the Ubbink instruction sheet.
|
Recommendations for accessibility:
For maintenance and cleaning purposes, the unit should always be easy to access.
|
Use of the installation for achieving good air quality in the house:
Good ventilation contributes to healthy air in the house, optimum comfort and good operation of the installation. When a multi-
position switch is used, proceed as follows:
Position 3: Kitchen/shower mode
|
100% of the design flow or of the maximum unit capacity
Position 2: Presence mode
|
60–70% of the design flow
Position 1: Absence mode
|
Ca 30% of the design flow
Fan symbol:
|
Holiday mode, Position of minimum ventilation (fixed setting)
Note: Apart from the design and installation recommendations given above, the national building and ventilation
regulations must be complied with. For any questions please contact Ubbink.
