4.2 Where/how to install
Topvex SC03-11 are meant for indoor installation. Topvex SC03-11 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.
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.
For size SC06-SC11 the units are delivered in parts on the pallet. For mounting procedure see figure 4
and figure 5. Connect the power supply for the electrical heating battery to the TTC (pos. 1). The cables
are marked TTC L1 OUT, TTC L2 OUT and TTC L3 OUT. Attach the fast couplings to the electric wires.
Connect the tubes for the pressure guard filter. Push the units together and fasten the assembly fitting
(pos. 2) with a hex key. Make sure that there is enough space behind the unit to tighten the bolts.
