3.3 Transport and storage
The Topvex SR/TR 03-06 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 in one piece containing all necessary components, wrapped in
plastic on a pallet for easy transportation.
When transporting the Topvex SR/TR 03-06 units, use a forklift placed on the gable of the unit (figure 7.)
Warning
The unit is heavy. Be careful during transport and mounting. Risk of injury through pinching. Use protective
clothing.

Installation |
4 Installation
4.1 Unpacking
Verify that all ordered equipment are delivered before starting the installation. Any deviation from the ordered equipment must be reported to the supplier of Systemair products.
4.2 Where/how to install
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).
Topvex SR/TR 03-06 can be installed outside if weather protected. An outdoor air section, ODS is available as
accessory.
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.
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 3 and figure 6).
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.
9
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.

4.3.1 Installation procedure
Warning
Beware of sharp edges during mounting and maintenance. Make sure that a proper lifting device is used.
Use protective clothing.
Warning
The units electrical connection to the mains power supply must be preceded by an all pole circuit breaker
with a minimum 3 mm gap.
Danger
• Make sure that the mains power supply 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.
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.
Installation |

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 power sup-
ply through the all pole circuit breaker, safety switch
(accessory). For Topvex SR 03-06 the wiring is led
through the gable of the unit. For Topvex TR 03-06
the wiring is led through the top of the unit casing. In
both cases the wiring is led directly to the electrical
connection box.
See enclosed wiring diagram, and (chapter 4.5.5) for
more information.
4.4 Supply air sensor
The supply air sensor is enclosed in the unit package on delivery. Mount the supply air sensor in the supply air duct after
the air handling unit (figure 10). See chapter 4.5.5 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.

4.5.2 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 outdoor 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
4.5.3 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 itself, installation of silencers before every inlet diffuser is recommended.
4.5.4 Electrical connections, components
All electric connections are made in the electrical connection box which can be found in the front of the unit (figure 12).
The hatch is removed by unscrewing four screws (figure 12).
13
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 (table 4.5.5).
Fig. 12 Opening the electrical connection box
Danger
• Make sure that the mains power supply 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 SR/TR 03-06 are equipped with a built in regulator and internal wiring (figure 13).
The figure shows the electrical connection box for the Topvex TR 03-06 units. The connection box for the Topvex SR
03-06 has the same layout and components with the difference that the electrical heater is situated in a separate
compartment.
