3.3 Transport and storage
The unit is delivered in one piece standing on a pallet for easy transportation using a forklift. The unit 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 complete with all necessary components, wrapped in plastic on a pallet for easy transportation.
When transporting the Topvex SX/C, TX/C units use a forklift placed on the gable of the unit.
Note:
Necessary parts like control panel, supply air sensor, mounting feet, drainage pipe with drain trap are
enclosed at delivery.
Warning
• The unit is heavy. Be careful during transport and installation. Risk of injury through pinching. Use
protective clothing.
• The unit must not be put into operation before the enclosed parts are removed and installed properly.
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
The unit is meant for indoor installation. 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.
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
(chapter 3.2.1.)
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.
Warning
• The unit should only be put into operation with the doors closed.
• 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.

8| Installation
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 3. 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 1 how the height
“H” corresponds to different maximum negative pressures. See figure 4 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
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
carries the weight of the unit. Perform the installation
in accordance with local rules and regulations.
2 Lift the unit in place.
3 Connect the unit electrically to the mains power sup-
ply through the all pole circuit breaker, safety switch
(accessory). The wiring is led directly to the electrical
connection box.
See enclosed wiring diagram, and chapter 4.6.5 for
more information.
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.
4.5 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 7). See chapter 4.6.5 to which terminals the sensor needs to be connected in the electrical
connection box. All other temperature sensors are built in to the unit from factory.

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.
151621 | A002

Installation | 13
4.6.4 Electrical connection, components
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.
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.
Reset the manual overheat protection for Topvex TX/C by pushing the red button on top of the electrical heater frame,
reachable by opening the units door. For Topvex SX/C it is reachable by unscrewing the lower hatch (to the re-heater
battery).
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.
