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.

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 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, 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 (refer to Figures 3 and 6 for space requirements).

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

4.3 Installing the Unit

The unit must be installed in the following positions (Figures 8 and 9).

Figure 8: Installation position (left hand unit). Shows airflow directions for supply, exhaust, outdoor, and extract air.

Figure 9: Installation position (right hand unit). Shows airflow directions for supply, exhaust, outdoor, and extract air.

Table 4: Symbol Description

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 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. 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 the help of the enclosed mounting feet.
4. Connect the unit electrically to the mains power supply 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 for which terminals the sensor needs to be connected in the electrical connection box. Other temperature sensors are built into the unit from the factory.

Figure 10: Installed supply air sensor (right hand connected unit). Shows sensor placement in the supply air duct.

4.5 Connections

4.5.1 Ducting

Figure 11: Connections and basic components (SR06 right hand unit, TR06 left hand unit). Illustrates the unit with various connection points and internal components.

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 taped 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).

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).

Figure 12: Opening the electrical connection box. Shows the location of the connection box and the screws to remove the hatch.

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.

4.6 Installing NaviPad Control Panel

The protection class of the NaviPad control panel is IP 54 and 0-50°C permitted ambient temperature. If NaviPad is mounted outdoor, 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.

4.6.1 Dimensions

NaviPad is the control panel for Systemair's Air handling units. NaviPad has an easy to understand menu structure and contains 13 languages.

Figure: Shows dimensions A, B, C, D, E, F for the NaviPad panel.

4.6.2 Mount NaviPad

The NaviPad control panel with 3 m cable, holder and screws are enclosed with the air handling unit. The air handling units have pre-drilled holes in the doors. Mount the control panel holder on the air handling unit and place NaviPad in the holder. NaviPad is connected to the panel outlet (pos 1) in the air handling unit at delivery.

See enclosed Quick guide for operating of the control panel.
