4.3 Frost protection
To prevent freezing of the heat exchanger at low outdoor temperatures, the appliance features a frost control.
Temperature sensors measure the temperatures in the appliance, when required a preheater is switched on. If in the
event of very low temperatures the preheater has insuffi cient capacity, stepless unbalance is created in the appliance.
The software ‘recognizes’ the appliance.
4.4 Plus version
The ‘Plus’ version is equipped with an extra control board with more connections for various applications.
This extra control board is located in a plastic housing behind the existing control board on top of the appliance.
It is also possible to remove the entire Plus pcb including casing from the appliance and mount it on, for example,
a wall separate from the heat recovery appliance; this can be handy in certain circumstances such as a poor WiFi
signal from the Plus pcb.
A standard heat recovery appliance can also later be modifi ed into a Plus version using the Plus pcb upgrade set.

5 Installation
5.1 Installation general
Installing the appliance:
1.
Placing the appliance ( Placing the appliance page 13 )
2.
Connecting the siphon and condensate discharge ( Connecting the condensate discharge page 15)
3.
Connecting the air ducts ( Connecting air ducts page 16)
4.
Electrical connections ( Electrical connections page 17)
The installation and installing should meet the following requirements:
|
Quality requirements of ventilation systems in homes, ISSO 61.
|
Quality requirements of balanced ventilation dwellings, ISSO 62
|
Regulations regarding the ventilation of homes and residential.
|
Safety provisions for low-voltage installations
|
The regulations for connecting indoor plumbing in homes and residential buildings.
|
Any additional regulations of the local power companies
|
The installation regulations of the Ubifl ux Vigor W225 appliance.
|
In addition to the above design and installation requirements and recommendations, the national building and
ventilation regulations must be respected.
5.2 Placing the appliance
The Ubifl ux Vigor W225 (Plus) appliance can be mounted onto the wall with the supplied mounting bracket. For a
vibration-free installation, the appliance must be mounted to a solid wall with a minimum mass of 170 kg/m
2
.
A gypsum block or metal stud wall does not suffi ce! Additional measures such as double panelling or extra studs are
required in that case. On request, a mounting support for fl oor mounting (with the same minimal mass) is available.
In addition, the following aspects must be taken into account:
|
The appliance must be installed in an insulated frost-free room (> 10 °C), in order to, for example, prevent
freezing of the condensate discharge
|
The appliance must be placed level.
|
The appliance must not be placed in a room with a high level of condensation (such as a bathroom).
|
In order to prevent condensation on the outside of the appliance, the installation room must be ventilated.
|
The installation room must be able to provide a condensate discharge with a suffi cient water seal and drop for
the condensed water.
|
Newly built houses with a lot of moisture from the construction work need to be ventilated in a natural manner
before being put to use.
|
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.
|
Make sure there is a free space of at least 25 cm above the appliance, for connecting the appliance and any
necessary servicing of the circuit board.
