WARNING!
The rotating impeller can crush/scrape fingers .
Ensure protection against contact before commissioning!
The following inspection work must be carried out or checked before commissioning:
– Check designated use of the ALB.
– Check permissible transport media temperature.
– Compare mains voltage to rating plate data.
– Check ALB for professional electrical installation.
– Check the waterproofing of the connection cable and tight clamping of the strands.
– Check protective conductor connection.
– Check all parts for tightness, particularly screws, nuts, protection guards. Do not loosen screws in the process!
– Check ALB for solid mounting! Terminal box / isolator switch and motorised impeller unit must be freely accessible.
– Ensure that the suction and outlet areas cannot be accessed by unauthorised persons.
– Check tightness of all connections (if necessary).
– Remove assembly residues from the fan or duct.
– Check free movement and direction of rotation of impeller; wear protective glasses when checking.
– Intake-side check valve must be accessible.
– Compare power consumption to rating plate data.
– Check ALB for vibrations and noises during test run. Check ALB for vibrations and noises during test run. In case of
excessive vibrations and/or noises, operation outside of the operating range of the ALB is to be assumed. In this case,
it is imperative that the manufacturer is contacted!
– Do not operate the ALB outside of the specified characteristic curve (see catalogue/internet). The ALB must run at
its prescribed operating point.
– By turning the main inspection switch to position 1, the fan will switch to standby mode.
The unit is switched on by pressing the touch screen.

Commissioning ALB with warm water heater battery

The mixing node (wiring diagram SS-1121/1122, Pt 9) is partly opened by the commissioning of the ventilation unit.
The water pump is activated if the heating flow is used by the pump control (wiring diagram SS-1121/1122, Pt 17). The
intake and outlet flaps also open (accessory; by client) (wiring diagram SS-1121/1122, Pt 16) and the fan will activate.
When the ALB is switched off, the fan will switch off first, the flaps will close and the water pump will switch off last.
The mixer will not be closed, it will stay in position. The ALB will be heated by the warm water heater battery.
If the frost protection is activated, the unit will immediately switch the fan off and the flaps will close . This measure
will ensure that there is no frost damage to the warm water heater battery or cold air entering the building . The
cold outside air will also not penetrate up to the warm water heater battery in the deactivated unit . The circulating
pump will be activated . The mixing node will open to ensure the water flow through the heat exchanger .
