3.3 Transport and Storage

The Topvex SR/TR units should be stored and transported protected against physical damage. They should be covered to prevent dust, rain, and snow from entering and damaging the unit and its components. The appliance is delivered as one piece, wrapped in plastic on a pallet for easy transportation. Use a forklift placed on the unit's gable for transport.

4. Installation

4.1 Unpacking

Verify that all ordered equipment is delivered before starting installation. Report any deviations to the supplier.

4.2 Where/How to Install

Place the unit on a horizontal, flat, and leveled surface that supports its weight. Preferably, install the unit in a separate room (e.g., storage, laundry room, attic). Topvex SR 09, 11 can be installed outdoors if weather-protected (ODS outdoor air section available as accessory). If installed in a cold place, keep the unit powered via the main switch to maintain warmth in the electrical cabinet. Ensure easy access to inspection doors for regular maintenance and for removing main components. Avoid placing the unit directly against a wall to prevent vibration issues from low-frequency noise. If unavoidable, insulate the wall. Position the outdoor air intake on the northern or eastern side of the building, away from other exhaust outlets.

4.3 Dividing the Topvex Air Handling Units

The two halves of the Topvex appliance are mounted together upon delivery. They can be divided for easier transport to the installation site.

4.3.1 How to Split the Topvex SR Unit

1. Remove the heat exchanger, supply air fan, and extract air filter.
2. Loosen the cable connectors.
3. The two halves are joined by 4 M10 screws, one in each corner.
4. Gables can be dismounted by removing 6 MRX M6 screws (PH2 bit).
5. Reassemble in reverse order.

Note: When reassembling, ensure pieces are connected correctly, referring to cable markings.

4.3.2 How to Split the Topvex TR Unit

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

4.4 Installing the Unit

The unit must be installed in the position shown in figures 5 and 6.

Figure 5: Installation position (left-hand unit)

Figure 6: Installation position (right-hand unit)

Table 1: Symbol Description

4.4.1 Installation Procedure

1. Prepare the mounting surface: ensure it is flat, leveled, and can support the unit's weight. Follow local rules and regulations.
2. Lift the unit into place.
   [Warning] Beware of sharp edges during mounting and maintenance. Use a proper lifting device and protective clothing.
3. Level the unit using the enclosed mounting feet.
4. Connect the unit electrically to the mains via the all-pole circuit breaker (safety switch) located inside the unit. Wiring is routed through the unit's gable (SR) or top casing (TR) to the electrical connection box. Refer to the wiring diagram and chapter 4.6.6.
   [Warning] The unit's electrical connection to the mains supply must be preceded by an all-pole circuit breaker with a minimum 3 mm gap.
   [Danger] Make sure the mains supply is disconnected before performing any maintenance or electrical work. All electrical connections must be carried out by an authorized installer according to local rules and regulations.

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 adjust the rotor's vertical position after installation. Remove the filter for access.

Adjustment:

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

4.5 Supply Air Sensor (Topvex SR 09, 11)

The supply air sensor is fitted in the supply air duct approximately 3 meters after the unit (see figure 8). Refer to chapter 4.6.6 for connection terminals in the electrical connection box. Other temperature sensors are factory-installed. The supply air sensor is included in the unit package.

4.6 Connections

4.6.1 Ducting

Diagram shows connections and basic components for left-hand connected units.

Figure 9: Connections and basic components in left-hand connected units

4.6.2 Condensation and Heat Insulation

Outdoor air and exhaust ducts must be well insulated against condensation, especially those connected to the unit. All ducts in cold rooms/areas require insulation (minimum 100 mm mineral wool with plastic diffusion barrier). For extremely low outdoor temperatures, additional insulation is needed, totaling at least 150 mm.

4.6.3 Silencers

Install silencers on both supply and extract air to prevent fan noise transfer via the duct system. For noise reduction between rooms and from the duct system itself, install silencers before each inlet diffuser.

4.6.4 Electric Connections

All electrical connections are made in the electrical connection box located at the front of the unit. The hatch is removed by unscrewing four screws. Ensure all electrical safety precautions are read and understood before operation. Refer to the enclosed wiring diagram for internal and external wiring. External connections for accessories are made to terminals inside the electrical connection box (chapter 4.6.6).

4.6.5 Electrical Connection Box, Components

Topvex SR/TR units feature a built-in regulator and internal wiring. The figure shows the electrical connection box for Topvex TR 09-15 units; the SR 09, 11 box has a similar layout but the electrical heater is in a separate compartment.
