4.2 Where/how to install
Topvex SR/TR are meant for indoor installation. Topvex SR 09, 11 can be installed outside if weather
protected. Place the unit on a
horizontal flat surface
. It’s important that the unit is completely levelled
before it is put into operation.
Place the unit preferably in a separate room (e.g. storage, laundry room, attic or similar). The electronic
components should not be exposed to lower temperature than 0°C and higher than +50°C.
If the unit is installed in a cold place it is important that the unit is not shut-off by the main switch. As long
as the main voltage is on the electrical cabinet will be kept warm also in cold climates. Although the unit is
turned off by the control system the current is on.
When choosing the location it should be kept in mind that the unit requires maintenance regularly and that
the inspection doors should be easily accessible. Leave free space for opening the doors and for taking
out the main components (figure 1 and figure 2).
Avoid placing the appliance against a wall, as low frequency noise can cause vibrations in the wall even if
the fan noise-level is acceptable. If this is not possible it is recommended to carefully insulate the wall.
The outdoor air intake of the building should if possible be put in the northern or eastern side of the building
and away from other exhaust outlets like kitchen fan outcasts or laundry room outlets.
4.3 Deviding the Topvex air handling units
On delivery the two halves of the Topvex appliance are mounted together. If necessary they can be
devided for easy transport to the site of installation figure 3 and figure 4.
