Commissioning
Once the installation of the ventilation system is complete, cor-
rect commissioning must be carried out to ensure proper func-
tion.
6.1 Requirements building
The ventilation system may only be commissioned if the build-
ing / ventilated residential unit is in a ready to move in state. Be-
fore switching on the system, all rooms must be freed from
building dust:
Interior fittings are completely installed
Wall openings and installation shafts have been correctly
closed
Plastering, grinding and painting work is complete
Floor coverings have been brought in
Internal doors are in place
Overflow openings are present
NOTE
º
The ventilation unit and all air inlets and outlets must be freely
accessible for commissioning.
6.2 Requirements for the
ventilation system
The installation of all components of the ventilation system
must be complete before commissioning can take place:
The ventilation unit and all components are installed
The condensate pipe has been connected correctly
The power supply is installed and working
Accessories (control elements, sensors etc.) are electrically
connected
Air duct systems are completely installed
Air inlets and outlets are installed
NOTE
º
A check must be carried out to ensure that all parts that come
into contact with the air flow are clean before switching on
the fans for the first time (subsequent cleaning may be
required).
6.3 Requirements for the
technician
The trained technician requires the following measuring equip-
ment for commissioning the ventilation system:
Multimeter
Temperature measuring device
Fan wheel anemometer with measuring funnel
Differential pressure gauge where applicable
NOTE
º
The commissioning must be carried out by a qualified
technician. Incorrect commissioning can result in inadequate
ventilation, increased odour problems, draughts and
inefficient operation!
6.4 Commissioning procedure
The following general procedure is used for commissioning the
ventilation system:
1) Visual inspection of the installed system
- Ventilation unit, condensate connection, filter
- Controller, sensors, accessories
- Air duct system, thermal insulation
- Special features (e.g. fireplaces)
2) Startup
- Switch on the power supply
- Carry out a function check on the device and accessories
3) Adjustment
- Volume flows, setting of the unit and valves
- Programming of the control
4) Instruction
- Instruction of the user / operator in the operation and
maintenance procedure
While calibrating the ventilation system, all internal doors and
windows must be closed.
NOTE
º
Settings in the service menu have a major impact on the
operation of the system and should only be carried out by a
qualified technician. Improper or incorrect settings can
reduce the efficiency of the system and result in
malfunctions!
ATTENTION!
!!
The system must be completed free of all safety health and
environmental risks. The manufacturer of the heat recovery
device is not liable for any damage.
