3.2.3 Electrical Data

3.3 Transport and Storage

The Topvex SR/TR units should be stored and transported in a manner that protects them from physical damage to panels, handles, or displays. They should be covered to prevent dust, rain, and snow from entering and damaging the unit and its components. The appliance is delivered as a single unit, wrapped in plastic on a pallet for easy transportation.

When transporting the Topvex SR/TR units, use a forklift placed on the gable of the unit.

[Warning] The unit is heavy. Be careful during transport and mounting. Risk of injury through pinching. Use protective clothing.

4 Installation

4.1 Unpacking

Verify that all ordered equipment is 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 is important that the unit is completely leveled before it is put into operation.

Preferably, place the unit in a separate room (e.g., storage, laundry room, attic, or similar).

Topvex SR 09, 11 can be installed outdoors if weather-protected. An outdoor air section (ODS) is available as an 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, even in cold climates.

When choosing the location, keep in mind that the unit requires regular maintenance and that inspection doors should be easily accessible. Leave free space for opening the doors and for taking out the main components (refer to diagrams for SR and TR units).

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 located on the northern or eastern side of the building and away from other exhaust outlets like kitchen fan exhausts or laundry room outlets.

4.3 Dividing the Topvex Air Handling Units

On delivery, the two halves of the Topvex appliance are mounted together. If necessary, they can be divided for easy transport to the site of installation.

4.3.1 How to Split the Topvex SR Unit

Follow these steps to split the Topvex SR unit:

1. Remove the heat exchanger, supply air fan, and the extract air filter.
2. Loosen the cable connectors.
3. The two halves of the unit are joined using 4 M10 screws, one in each corner.
4. It is possible to dismount the gables by removing 6 MRX M6 screws with a PH2 bit tool.

Reassemble in the reverse order.

Note: When reassembling the pieces, make sure they are connected correctly – refer to cable markings on the side of the cables.

4.3.2 How to Split the Topvex TR Unit

Follow these steps to split the Topvex TR unit:

1. Remove the heat exchanger, extract fan, and the extract air filter.
2. Remove the plate.
3. Loosen the cable connectors.
4. Remove the 7 M10 screws that join the two halves of the appliance.

4.4 Installing the Unit

The unit must be installed in the following positions (refer to diagrams for left and right hand units).

Diagrams show installation positions with arrows indicating airflow:

• Black upward arrows: Supply air
• Black downward arrows: Exhaust air
• Hatched upward arrows: Outdoor air
• Hatched downward arrows: Extract air

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.

[Warning] The unit's 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. Ensure the surface is flat, leveled, and supports the weight of the unit. Perform the installation in accordance with local rules and regulations.
2. Lift the unit into place.
3. Level the unit with the help of the enclosed mounting feet.
4. Connect the unit electrically to the mains power supply through the all-pole circuit breaker and safety switch (accessory). The wiring is led through the gable of the unit (Topvex SR 09, 11) or through the top of the unit casing (Topvex TR 09-15) directly to the electrical connection box. Refer to the enclosed wiring diagram and chapter 4.6.6 for more information.

4.4.2 The Rotors Vertical Position (Topvex SR 09, 11)

To achieve optimal sealing against the rotor's brush strip and the chassis frame, check and, if necessary, adjust the rotor's vertical position when the unit is installed. Remove the filter for easy access.

Adjustment Steps:

1. Loosen the two screws.
2. Remove the cover.
3. Adjust the rotor's height by loosening the locking screw to the axle of the rotor.
4. Adjust the rotor's vertical position by adjusting the two screws on the rotor bracket.
5. After adjustment, tighten the locking screw to the rotor axle (3), mount the cover (2), and fasten the screws (1).

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. Refer to chapter 4.6.6 for connection terminals in the electrical connection box. Other temperature sensors are built into the unit from the factory.

4.6 Connections

4.6.1 Ducting

Diagram showing connections and basic components in left-hand connected units. The diagram labels connection points A, B, C, D for supply, exhaust, outdoor, and extract air respectively, and components 1 through 8.

4.6.2 Condensation and Heat Insulation

Outdoor air ducts 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 a 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 taped 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 on both 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.

4.6.4 Electric Connections

All electric connections are made in the electrical connection box, located in the front of the unit. The hatch is removed by unscrewing four screws.

The unit must not be put into operation before all electrical safety precautions have been read and understood. Refer to the enclosed wiring diagram for internal and external wiring.

All external connections to possible accessories are made to terminals inside the electrical connection box (chapter 4.6.6).

[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.

4.6.5 Electrical Connection Box, Components

Topvex SR/TR units are equipped with a built-in regulator and internal wiring.

The figure shows the electrical connection box for the Topvex TR 09-15 units. The connection box for the Topvex SR 09, 11 has the same layout and components, with the difference that the electrical heater is situated in a separate compartment.

Note: The 24V HMI connection is dedicated for the display. The connection is only for HMI and no other connections are permitted.

4.7 Installing NaviPad Control Panel

The NaviPad control panel has a protection class of IP 54 and a permitted ambient temperature range of 0-50°C. If NaviPad is mounted outdoors, the panel needs to be protected against direct UV radiation. Communication between the panel and the controller in the cabinet is possible with up to 100 meters of cable.

4.7.1 Dimensions
