NOTE
This list does not replace the detailed descriptions with instal-
lation and safety notes in the instruction manuals. The instal-
lation instructions for the ventilation unit and its accessory
components must be observed.
Ventilation unit
 Installation room dry and free from frost
 Ventilation unit installed horizontally and vertically
aligned (spacers on the bottom corners)

Vibration-reducing wall mounting for lightweight con-
struction walls
 Sufficient space for maintenance work
 Power supply connected, all-pole power disconnec-
tion possible and accessible (plug, switch or fuse)

External control element and room air sensor (if fitted)
installed and connected
 Outside air preheating register (if fitted) installed and
connected, installation position and direction of air
flow checked (observe the installation instructions for
the heating register)

Consultation with the district master chimney sweep if
fireplace present (fireplace function activated or nec-
essary ext. safety equipment installed)
Condensate pipe
 Condensate pipe connected to the ventilation unit
without leaks, fixed in place with a fastening clip

Frost-free installation of the condensate pipe over the
entire distance and pipe installed with a slope (con-
densate hose not sagging and not buckled)

Negative pressure on the condensate connection! Si-
phon installed on the ventilation unit to prevent false
air intake (siphon can dry out, a ball siphon with nega-
tive pressure protection and dry running protection is
recommended!)

Siphon filled with water, entire condensate drainage
system checked for correct function (water filled in the
condensate tray)

Free inlet from the siphon on the unit in a funnel on the
drainpipe (no direct connection between the unit and
the drainpipe, intake of sewer gases must be reliably
prevented!)
 Drainpipe fitted with another siphon to prevent odours
from the waste water pipe
Air duct system
 Vibration transmission must be avoided, all air ducts
are connected flexibly to the ventilation unit

Vibration-reducing measures on mountings, brackets,
consoles (if required)
 Sound absorbers or sound-absorbing ventilation
hoses installed (in the supply air and exhaust air duct
and in the outside air and extract air duct)
 Wall or ceiling openings are closed
 Air duct system inside the thermally insulated building
shell

Thermal insulation on the outside air and extract air
duct (steam-resistant, sufficiently strong, not dam-
aged or crushed)

Air duct connections and connection points masked
with additional thermal insulation strips
 The air duct system must be installed air-tight! Con-
nections and connection points of the duct and ther-
mal insulation are air-tight and masked where applica-
ble (leaks in the air duct and leaking connections can
result in condensate formation - ensure that the out-
side air and extract air pipe connections in particular
are air-tight!)
 Air pipes, in particular flexible ventilation hoses, must
not be crushed or heavily buckled (risk of increased
pressure drops or reduced thermal insulation!)
 Outside air and extract air inlets/outlets protected
from leaves, soiling, odours, ingress of moisture, ex-
pected snow levels taken into account
 Supply air and exhaust air valves (ventilation grilles) in-
stalled
Commissioning
 Residential unit ready to move in, building work com-
plete, openings closed, interior fittings completely fin-
ished, no building dust
 Internal doors in place, unhindered overflow from sup-
ply air areas to exhaust air areas is achieved with un-
dercut doors or ventilation grilles
 Direction of air flow on air inlets and outlets checked,
air circuit not covered, obstructed, sealed

Outside air, exhaust air and bypass filters in the unit
and clean (replace if necessary)
 External control unit and room air sensor registered in
the service menu

Volume flows set in the service menu

Ventilation system calibrated and set

Function check (display working correctly, operating
modes can be set, remote control, heating register)
 Room air sensor (if fitted): Function checked in Auto-
matic operating mode (caution: response only after
approx. 15 min warm-up phase!)
 Settings adapted in the user and service menu (e.g.
bypass, sensor sensitivity)
Instruction
 Instruct operators and users in the operation and ex-
plain the proper use

Inform operators and users of the necessary mainte-
nance measures (filter change, restart the interval time
for the filter signal)

Reference to further maintenance measures to be car-
ried out by the engineer
