Installation
Chapter 5
5.1 Installation general
Installing the appliance
1. Placing the appliance (§5.2)
2. Connecting the condensate discharge (§5.3)
3. Connecting the ducts (§5.4)
4. Electric connection
Connecting the mains power, multiple switch and, if neces
-
sary, the OpenTherm/eBus coupler (§5.5)
Installation must take place under:
• Quality requirements ventilation systems dwellings.
•
Quality requirements balanced ventilation in dwellings.
• The regulations for ventilation of dwellings and residential
buildings.
• The safety regulations for low-voltage installations.
• The regulations for connection to interior sewers in dwel
-
lings and residential buildings.
• Any additional regulations of the local utilities.
• The installation instructions for the Ubiflux.
5.2 Placing the appliance
The Ubiflux can directly be mounted to the wall using the sus
-
pension brackets supplied for that purpose. For a vibration-free
result the appliance must be mounted to a solid wall with a
minimum mass of 200 kg/m
2
. A gypsum block or metal stud wall
does not suffice! Additional measures such as double panelling
or extra studs are required in that case. On request, a mounting
support for floor mounting is available. In addition, the following
aspects must be taken into account.
• The appliance must be placed level.
• The installation room must be such that a good conden
-
sate discharge with air trap and pitch for condensate can
be made.
• The installation room must be frost-free.
• Make sure there is a free space of at least 70 cm at the
front of the appliance and a free headroom of 1.8 m for
cleaning the filters and carrying out maintenance.
• Make sure there is a free space of at least 20 cm above the
display cover so it can always be removed.
5.4 Connecting ducts
The air extract duct does not have to be fitted with a control
valve. The appliance itself controls the air flow rates.
To prevent condensation on the outside of the outdoor air
supply duct and the air extract duct from the Ubiflux, the
-
se ducts must be provided with an external vapour bar
-
rier as far as the appliance. If Ubbink synthetic (EPE)
pipe is used here, additional insulation is not necessary.
For compliance with the maximum installation noise level
of 30 dB, it will have to be assessed for every installation
specifically what measures will be required to limit the
noise.
At least a muffler with a length of not less than 1.5
m is required, but additional measures may be nec
-
essary. Please contact the Brink Consultancy De
-
partment if you have any questions on this subject.
Pay attention to crosstalk and installation noise, also for incor
-
porated ducts. Design the duct with separate branches to the
valves to prevent crosstalk. If necessary, the supply ducts must
be insulated, for instance when they are installed outside the
insulated envelope.
Preferably use Ubbink incorporated ducts. These ducts have
been developed with a view to a low duct resistance.
A duct diameter of 180 mm is required for the Ubiflux W400 and
W450, for the Ubiflux W300 can suffice with a duct diameter of
160 mm.
5.3 Connecting the condensate discharge
The condensate discharge line for the Ubbink Ubiflux HR is fed
through the lower panel. The condensate must be discharged
through a drainpipe.
The condensate discharge comes separately with the applian-
ce and the installer must screw it into the underside of the ap
-
pliance. This condensate discharge connection has an external
connecting diameter of 32 mm.
The condensate discharge line can be
glued to it, if necessary
using a square bend. The installer can glue the condensate
discharge in the desired position in the lower part of the ap-
pliance. The drain must discharge under the water level in the
U-trap
Before connecting the condensate discharge to the appliance,
pour water into the U-trap to create an air trap.
