Important Information Before You Mount the Unit

Read the instructions in this chapter carefully before you begin.

It is recommended to drill duct holes 10-15 mm larger than indicated on the drawings. This allows for subsequent insulation, prevents direct contact with the wall, and facilitates the restoration of a vapor barrier.

Minimum Distance to Building Parts and Room Layout

AM 950 C

Correct positioning is crucial. The following sketch shows important distances to consider before installation:

Figure 5: Minimum distance to building parts, AM 950 C unit illustrates:

Obstacles in the room affect the airflow from the AM 950 C unit. Consider the room layout when choosing the position. See examples of correct vs. incorrect installation in Figure 6.

Figure 6: Correct installation vs. incorrect installation shows visual examples of proper and improper unit placement.

AM 950 F

Correct positioning is important. The unit requires free space for its door to open. Room obstacles can affect airflow, so consider the room layout when selecting the position. Key distances include:

• A minimum distance of 10 mm on the left-hand side (from the front) is required to open the unit door.
• A minimum distance of 1150 mm is required in front of the unit for the door to open.

Obstacles like large ceiling lamps can disrupt airflow, creating unwanted flow directions, as illustrated in Figure 7: Obstacles can create unwanted flow directions - illustrative example only.

Tools and Accessories

Before starting the mounting of the AM 950 C or AM 950 F unit, the following tools and accessories are needed:

• Lifting equipment appropriate for the unit weight (min. 350 kg), e.g., a pallet loader.
• A core drill (min. Ø315 mm, see Information Box on page 13).
• Common hand tools, including a spirit level.
• Sealants and sealing tape.
• Clean underlay to prevent scratches (e.g., strong cardboard, thick plastic, a blanket).
• Laths/battens/blocks of wood to support the unit when lifting.

Depending on the customer's order, duct pipes, grilles, and a vapor barrier may also be required. Installation cannot be done correctly without this equipment.

The Mounting Process

AM 950 C

The mounting process for the AM 950 C unit involves eight steps:

1. Disassemble the side and front covers.
2. Disassemble the rear bracket.
3. Mark drill holes for the brackets and ducts.
4. Drill holes.
5. Mount the bracket.
6. Mount the unit.
7. Reassemble the side and front covers.
8. Mount duct pipes and grilles and Condensate drainage (option).

The rear bracket is mounted on the unit when shipped and must be disassembled first. The front cover also needs to be removed to attach the unit to the ceiling. Subsequently, mark and drill holes for brackets and ducts. The rear bracket is then mounted, followed by lifting and mounting the unit onto it. Finally, the side and front covers are reassembled. Duct pipes, grilles, and the drain are then mounted to complete the process. Electrical installation, including control panels, is performed separately as per the Installation manual. After mounting, fill out the form on page 2 with unit details.

Disassemble the Side and Front Covers

1. Disassemble the left-hand side cover, as shown in Figure 8: Disassemble the left-hand side cover. Place the cover on a protective underlay to prevent scratches.
2. Disassemble the right-hand side cover, as shown in Figure 9: Disassemble the right-hand side cover. Place the cover on a protective underlay.
3. Disassemble the front cover, as shown in Figure 10: Disassemble the front cover. Place the cover on a protective underlay.

Keep the bolts and washers for reassembly.

Disassemble the Rear Bracket

Disassemble the rear bracket as shown in Figure 11: Disassemble the rear bracket, left-hand side seen from behind and Figure 12: Disassemble the rear bracket, right-hand side seen from behind.

Keep the bolts for mounting the unit onto the bracket.

Mark Drill Holes for the Brackets and Ducts

Rear and Front Brackets

1. Hold the rear bracket against the wall and ceiling, ensuring it is level (see Figure 13: Mark drill holes for the rear and front brackets).
2. Mark the holes for the rear bracket.
3. Mark the holes for the front bracket (part of the unit, cannot be disassembled) using Figure 14: Distances from rear bracket to front bracket and Table 8.

Duct

1. Hold the rear bracket against the wall and ceiling, ensuring it is level and in the same position as before.
2. Mark the center of the duct holes using Figure 15: Mark drill holes for the ducts and Table 9.

The rear bracket has notches on top to mark the center of duct holes, serving as a reference for measurements.

Drill Holes

Drill the holes. Ensure the correct gradient and size for duct holes, as per the Information Box on page 13. Figure 16: Drill holes illustrates this step.

Mount the Bracket

Mount the bracket using all attachment points on the wall and ceiling. Figure 17: Mount the bracket shows the process.

Mount the Unit

Use appropriate lifting equipment (refer to section 5.2). Place a protective underlay between the lift and the unit to prevent scratches (Figure 18: Lift the unit up and onto the bracket). Lift the unit onto the bracket, ensuring it is hinged correctly. Prevent electrical wires and drain hoses from being squeezed between the wall/ceiling and the unit. Ensure the unit is level.

Attach the unit to the bracket on both sides using the large bolts previously removed (see Figure 19: Attach the unit to the bracket, left-hand side and Figure 20: Attach the unit to the bracket, right-hand side). The bracket should fully support the unit. Check that the unit is level.

Mount the front bracket onto the ceiling using all attachment points (see Figure 21: Mount the front bracket to the ceiling). Check that the unit is level.

Reassemble the Side and Front Covers

Reassemble the front and side covers using the previously removed bolts (see Figure 22: Reassemble the left-hand side cover, Figure 23: Reassemble the right-hand side cover, and Figure 24: Reassemble the front cover).

The next step is to mount duct pipes and grilles; continue with section 6.3.

AM 950 F

The mounting process for the AM 950 F unit involves three or four steps:

1. Mark and drill duct holes.
2. Mount the unit.
3. Mount duct pipes and grilles + sealing.
4. Connect the drain (if supplied with a condensate pump and drain).

Figures in this section refer to the HH version. For VV, SSR, or SSL versions, consider duct hole locations and refer to Appendices B, C, or D for dimensional drawings. Electrical installation follows mounting, as per the Installation manual. After mounting, fill out the form on page 2 with unit details.

Mark and Drill Duct Holes

Ensure correct gradient and size for duct holes, as per the Information Box on page 13.

1. Mark the holes for the ducts.
2. Drill duct holes.

Consider wearing a face mask or similar protection equipment to avoid inhaling dust particles during drilling.

Mount the Unit

1. Before lifting the unit upright, place laths/battens/blocks of wood as shown in Figure 25: Place laths/battens/blocks of wood before lifting the unit. This prevents damage to the height-adjustable feet. Ensure the feet are as short as possible.
2. Raise the unit into an upright position and place it in its final position, as close to the wall as possible. A pallet loader can be used for moving (see Figure 26: Move the unit into place).

3. Adjust the feet to make the unit level (see Figure 27: Adjust the feet to level the unit).
4. Attach the brackets on top of the unit to the wall using screws suitable for the wall material. Ensure the unit is firmly secured to the wall (see Figure 28: Attach the bracket on top of the unit to the wall).

Mount Duct Pipes and Grilles

This section describes fitting ducting and sealing. Materials and methods depend on the customer's order, options, and site. The steps are:

1. Mount the unit (already done).
2. Fit the ducting.
3. Mount the outside grille.

Figure 29: Duct pipes and grilles - general overview provides an overview, applicable to units with ducts on the back or through the ceiling.

Important Information:

• Duct length is calculated based on wall/roof thickness.
• Ensure duct pipes are not twisted or compressed against the unit's spigots, as this increases noise.
• Intake and exhaust air ducts must be insulated against condensation if within the building envelope, with service access provided.
• Intake and exhaust air ducts must be insulated against noise if visible, with service access provided.
• Sealant must be applied inside and outside (see section 6.3.1).
• An outside grille must be mounted. Refer to the Airmaster website for information on the Boomerain® grille.

Sealing

Figure 30: Sealing the gaps around ducts, sectional drawing depicts a unit with ducts through a wall. The unit (labeled '1') is installed on the inner wall.

Figure 30 shows:

• 1: Unit
• 2: Wall
• 3: Duct and duct pipe
• 4: Sealing points on the outside

1. Apply sealant to the duct's outside edges (point '4' in Figure 30).
2. Apply sealant to the inside around the base and sides of the unit, between the unit and the wall (see Figure 31: Sealing around the unit).

Use a sealant that retains long-term elasticity or expanding sealing tape for a flexible seal, depending on the wall condition.

Condensate Drainage (Option)

The AM 950 unit may be fitted with a condensate pump and hose. Drainage connections depend on the site.

Drainage can be via a waste-water pipe or through the outer wall. If connected to a waste-water pipe, install a water trap to block odors emanating from the system (see Figure 32: Water trap to avoid odors).

If the drainage hose is led through the outer wall, it must be protected against ice formation. Drill a hole with a suitable diameter and an outwardly sloping gradient of 1-2%. Seal the joint between the hose and the outer wall.
