Installation & Disassembly
4. Installation
4.1 Installation of unit
•
Ensure that the unit is installed firmly on a level
and horizontal surface.
•
Prior to connecting the unit to the duct system,
all openings must be closed. Then connect the
ducts to the unit. See the air direction symbols
at the connection points.
•
Avoid connecting bends directly to the unit's
connection points. The duct system should be
connected in such a manner that vibrations from
the unit cannot be transferred to the duct system
and the surroundings.
•
Installation should be carried out in such a
manner that the weight of the duct system and
its components does not overload the unit.
•
During installation, ensure that there is sufficient
room to service the unit in front of the unit.
•
If the unit is installed against a wall, there is
a risk that vibrations will be transferred to the
adjacent room and may cause noise problems.
The recommended distance between the unit
and walls is 400 mm. If this is not possible,
install the unit against a wall with a room that is
not sensitive to noise. Where possible, insulate
walls and floors using heavy insulation to prevent
noise problems.
•
Ensure that supply and exhaust air ducts are
suitably insulated to avoid condensation.

Prior to connecting the unit, ensure that voltage
readings correspond to the unit’s specification.
Incoming cables are provided with suitable switches
that comply with applicable requirements for
electrical installations and are connected to the
terminal in the unit.
•
Install the unit’s temperature sensor GT1 for
supply air. This should be mounted as far away
from the unit as possible, but before the first
branch.
5. Operation/Control & Rules
