3.3 Transport and storage
The Topvex SC03-11 should be stored and transported in such a way that it is protected against physical damage that
can harm panels, handles, display etc. It should be covered so that dust, rain and snow cannot enter and damage the
unit and its components. The appliance is delivered with all necessary components, wrapped in plastic on a pallet for
easy transportation.
When transporting the Topvex SC03-11 units use a forklift placed on the gable of the unit. For size SC06-SC11 the units
are delivered in parts on the pallet.
Warning
• The unit is heavy. Be careful during transport and mounting. Make sure that proper lifting device is used.
Risk of injury through pinching. Use protective clothing.
• Be careful so the unit don't tip over.

4 Installation
4.1 Unpacking
Verify that all ordered equipment are delivered before starting the installation. Any deviation from the ordered equip-
ment must be reported to the supplier of Systemair products.
4.2 Where/how to install
Danger
• Make sure that the mains to the unit is disconnected before performing any maintenance or electrical
work!
• All electrical connections must be carried out by an authorized installer and in accordance with local rules
and regulations.
Caution
• Take care not to damage the water battery when connecting water pipes to connectors. Use the spanner
to tighten the connection.
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 inspec-
tion 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 to figure 6. Con-
nect 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.

4.3 Condensation drain
The unit must be connected to the condensation drain, which is enclosed upon delivery. The drainage needs to be con-
nected on the exhaust air side of the heat exchanger at the bottom of the unit figure 7. If the unit is to be used for cool
recovery the normally plugged drainage outlet needs to be connected as well to a separate tube and water lock
(accessories).
Use the enclosed connection tube, which needs to be cut down to the appropriate height. See table 2 how the height
“H” corresponds to different maximum negative pressures. See figure 8 for dimensions and assembly.
Note:
When installed in a non heated place the drain pipe and trap needs to be insulated well to prevent the water
from freezing.

4.4.1 Installation procedure
Danger
• Make sure that the mains to the unit is disconnected before performing any maintenance or electrical
work!
• All electrical connections must be carried out by an authorized installer and in accordance with local rules
and regulations.
Warning
• The units electrical connection to the mains must be preceded by an all pole circuit breaker with a
minimum 3 mm gap.
• The door handles are only intended to be used during the installation and service. These must be
removed before the unit is put into operation to ensure the required level of safety for the unit.
• The unit must be duct connected or in some other way provided with protection so that it is not possible
to come in contact with the fans through the duct connections.
Warning
Beware of sharp edges during mounting and maintenance. Make sure that a proper lifting device is used.
Use protective clothing.
1. Prepare the surface where the unit is to be mounted. Make sure that the surface is flat, levelled and that it
supports the weight of the unit. Perform the installation in accordance with local rules and regulations.
2. Lift the unit in place.
3. Level the unit with help of the enclosed mounting
feet.
4. Connect the unit electrically to the mains through the
all pole circuit breaker (safety switch), which is enclosed
inside the unit on delivery. The wiring is led through the
top of the unit.
See enclosed wiring diagram, and below table for more
information.

4.5 Supply air sensor
The supply air sensor is fitted in the duct ca. 3 m after the unit in the supply air duct (figure 11). See table 4.6.5 to which
terminals the sensor needs to be connected in the electrical connection box. Other temperature sensors are built in to
the unit from factory. The supply air sensor is enclosed in the unit package on delivery.

4.6.2 Condensation and heat insulation
Outdoor air duct and exhaust ducts must always be well insulated against condensation. Correct insulation installation
on ducts connected to the unit is especially important. All ducts installed in cold rooms/areas must be well insulated.
Use insulating covering (minimum 100 mm mineral wool) with plastic diffusion barrier. In areas with extremely low out-
door temperatures during the winter, additional insulation must be installed. Total insulation thickness must be at least
150 mm.
Caution
• If the unit is installed in a cold place make sure that all joints are covered with insulation, and tape well
• Duct connections/duct ends should be covered during storage and installation
• Do not connect tumble dryers to the ventilation system
4.6.3 Silencers
To avoid fan noise being transferred via the duct system, silencers should be installed both on supply and extract air.
To avoid noise being transferred between rooms via the duct system and also to reduce noise from the duct system it-
self, installation of silencers before every inlet diffuser is recommended.
137667 | A001

Installation | 15
4.6.4 Electric connections, components
All electric connections are made in the electrical connection box which can be found in the front of the unit. The hatch
is removed by unscrewing four screws.
The unit must not be put into operation before all the electrical safety precautions have been read and understood. See
the enclosed wiring diagram for internal and external wiring.
All external connections to possible accessories are made to terminals inside the electrical connection box.
Danger
• Make sure that the mains to the unit is disconnected before performing any maintenance or electrical
work!
• All electrical connections must be carried out by an authorized installer and in accordance with local rules
and regulations.
Topvex SC03-11 are equipped with a built in regulator and internal wiring.
