Commissioning

7.1 General

Once installation of the ventilation system is complete, correct
commissioning must be carried out to ensure proper function.
The system operator must use the installation instructions for
information on operating and maintenance procedures.
In the event of a defect or extraordinary circumstances (e.g. if
the system is or has been under water due to a natural disaster),
operation must be ceased immediately. Switch off the power
supply and consult an engineer.

7.2 Building requirements

The ventilation system may only be commissioned if the build-
ing / ventilated residential unit is in a ready to move in condi-
tion. Before switching on the system, all rooms must be cleared
of 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 fitted
Internal doors are in place

Overflow openings are present

HINWEIS
NOTE
The ventilation unit and all air inlets and outlets must be freely
accessible for commissioning.
7.3 Ventilation system
requirements
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 are electrically connected
Air duct systems are completely installed

 Air inlets and outlets are installed
Filters are in place and clean

CAUTION!
Commissioning only with air ducts connected
HINWEIS NOTE
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 (additional cleaning may be re-
quired).

7.4 Engineer requirements

The trained engineer 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

HINWEIS
NOTE
The commissioning must be carried out by a qualified engi-
neer. Incorrect commissioning can result in inadequate venti-
lation, increased odour problems, draughts and inefficient op-
eration

7.5 Commissioning procedure

The following general procedure is used for commissioning the
ventilation system:
1) Visual inspection of the installed system
Ventilation unit, condensate connection, filters

 Controller, sensors, accessories
Air duct system

 Special features (e.g. fireplaces)
2) Startup
 Switch on the power supply
Carry out a function check on the unit and accessories

3) Adjustment
 Volume flows, setting of the unit and valves
Programming the control

4) Instruction
Instruction of the user in operation and maintenance pro-

cedures
While calibrating the ventilation system, all internal doors and
windows must be closed.
The settings required for commissioning are made in the ser-
vice menu (see Operation chapter).
The commissioning report for the ventilation systems helps to
ensure that all commissioning points are covered and docu-
mented.
HINWEIS NOTE
Settings in the service menu have a major impact on the oper-
ation of the system and should only be carried out by a quali-
fied engineer. Improper or incorrect settings can reduce the
efficiency of the system and result in malfunctions!
HINWEIS
NOTE
Once the system is complete, there must not be any safety,
health or environmental risks. The heat recovery device man-
ufacturer is not liable for any damage.
