1 Introduction This manual is a guide for mounting an AM 50. The full documentation package contains a Mounting manual and an Operation and Maintenance manual. Both manuals are available at https://www.airmaster-as.com/en/ The manual should be passed along to and saved by the air handling unit’s owner.
We recommend that AM 50 is mounted directly to the electrical installation and that the supply is dimensioned and mounted accordingly. Alternatively, AM 50 can be connected to a light bulb socket or similar.
AM 50 is not designed for wet rooms or kitchens. Should you wish to use the AM 50 in wet rooms or kitchens, the unit should be used in tandem with an air exhaust system in compliance with existing building regulations.
Direct link: Documentation, choose ’EU Declaration of Conformity’. 3.7 Certificates AM 50 is Eco Label certified, please see Appendix B on page 36. The most recent version is always available on our website. Direct link: Documentation, choose ’Eco Labels’.
4 Transportation and storage AM 50 is packed in a cardboard box. During transport, the box must be tied up in such a way that it will not move or shift. Make sure that the box is not dropped or otherwise damaged during handling.
5 Installation 5.1 Installation accessories and tools Before installing AM 50 you will need to have the following installation accessories ready: • Elastic sealant • DAFA sealing tape, illmod 600, 15/5-10 (grey color) • 3x0,75 mm cable. It is not possible to do a correct installation without this equipment.
5.3 Minimum distance to the building parts To ensure the maximum efficiency of AM 50, the provided minimum distances should be respected. The minimum distances ensure that the unit can easily distribute the air into the room pleasantly and mutedly.
5.5 Hole drilling Drill a Ø255 mm hole in the wall, see Figure 6 below. AM 50 needs a 2-degree slant toward the façade. This is important to ensure that any condensation can leak out and to prevent rain from leaking inside.
5.6.1 Ø250 mm The Ø250 mm tube (4) is sawed the length of A + 10 mm, measured from the end of the tube with the 4 holes, see Figure 8 below. Figure 8 - Shortening of the Ø250 mm tube Clean any dust and impurities off the tube and its sawed-off edge.
5.7 Outside mounting 5.7.1 Preparation of outside hood No tools are necessary. The outward-facing side of the outside hood (1) is placed on a piece of cardboard from the packaging on top of a steady surface. The outside hood comes with pre-mounted strips. Press the Ø90 tube (3) with the milled grooves against the inside of the hood so it clicks on.
5.7.2 Mounting of sealing band on the outside hood The outside hood is prepared with the included sealing band (8). The sealing band should be placed on the outside of the Ø250 tube and inserted down into the outside hood, see Figure 12 below. Figure 12 - Sealing band on the outside hood 5.7.3 Sealing tape on façade wall The DAFA sealing tape –...
5.7.4 Applying sealant between sealing tape and façade wall If the facade is irregular, e.g. a blank wall with recessed joints, the holes created by the joints under the sealing tape should be filled out with an elastic sealant, see Figure 14 below. We recommend that you use a sealant with the same color as the joints.
Figure 16 - Outside hood, level Press the outside hood against the sealing tape. The outside mounting is now complete. Now the internal mounting is carried out followed by the joining and fastening of the two units. 19/40...
5.8 Internal mounting NOTICE It is necessary to access and decide whether the air handling unit should be mounted with a visible or hidden 230V cable routing before the internal mounting begins, see section 5.9 for further information. If a hidden cable routing is desired, you need to drill a hole in the wall cover (5) before it is mounted, see section 5.9.5 on page 30.
Figure 18 - Application of elastic sealant to the wall cover 5.8.3 Mounting the wall cover While holding the 4 strips from the outside hood back, the wall cover’s collar is inserted into the wall and the Ø250 mm tube (4). Press the wall cover against the wall and make sure it is level, see Figure 19 below. Any excess sealant is wiped off.
5.8.4 Fixation and tensioning The internal wall cover needs to be held in place and tensioned to the outside part which is done with the strips. All figures are located on the next page. The four strips located on the outside hood are guided through the holes in the internal wall cover, see Figure Make sure that they are not twisted, crossing each other, or the cables inside the tube.
Figure 20 - Strips from the outside hood are guided into the Figure 21 - One loose strip is connected to each of the strips internal wall cover Figure 22 - The strips are pushed down Figure 23 - Bend and cut the “mounted” strips Figure 24 - Bend and cut the other strips Figure 25 -The internal wall cover is assembled 23/40...
5.9 Electrical connection The standard electrical connection is carried out with a visible 230V cable from above. Should a visible cable routing from the right, left, or below be desirable, this is also possible. Likewise, it is possible to have hidden cable routing. 5.9.1 24V Cable connection and wiring Remove the cover over the wire terminal in the upper left.
Thoroughly seal the cable hole with sealant to avoid any air leaks in AM 50, see Figure 28 below. Figure 28 - Sealing cable hole Reattach the cover over terminal 1 again. Now begin connecting and wiring the 230V cable, either from above (section 5.9.2), from the right or below (section 5.9.3), or the left (section 5.9.4).
5.9.2 230V Cable connection, top (standard) Detach the terminal 2 cover, see Figure 30 and Figure 31 below. Attach the cable to terminal 2 with wire colors matching the internal wires, see Figure 31. Tighten the cable clamp and reattach the cover. Figure 30 - Terminal 2 Figure 31 - 230V cable connection in Terminal 2 26/40...
5.9.3 230V cable connection from the right or bottom The cable connection from the right or the bottom is performed similarly. Below is the description for installing the cable on the right side. Detach the cover over terminal 2, see Figure 30 and Figure 31. Disconnect the cable from terminal 2.
Figure 35 - 230V cable connection from the right with cable clamp Should the cable come from below, connect terminal 2 on the pins at the bottom, see Figure 36 below. The cable clamp and cover are moved from the top to the bottom. Figure 36 - Location of terminal 2 with cable routing from below 28/40...
5.9.4 230V cable connection from the left Detach the covers at the top and to the left, and remove the internal cable, see Figure 37 below. Reattach the top cover again. Connect the 230V cable to terminal 3 with the shown color codes, see Figure 38 below. Move the cable clamp from the top of the cover and attach it by terminal 3, see Figure 39.
Figure 39 - Cable connection with cable clamp in terminal 3 5.9.5 230V hidden cable connection Hidden cable routing is also possible. To hide the cable you need to drill a hole for the cable in the wall cover by/between the two screw towers, see Figure 40 below. Once this is done the electrical installation is done as described for the visible cable connection, however, without the use of the cable clamp.
5.10 Mounting the air handling unit 5.10.1 Half-hole for cable (Only for visible cable routing) Before the air handling unit can be mounted, it is necessary to make a hole for the 230V cable. Cut a half-hole for the cable in the back edge of the air handling unit’s internal hood at the chosen cable orientation (top, right, left or below), see Figure 41 below.
Figure 44 - The internal cover is mounted on the ventilation unit The cover is detached by pulling it out from the wall. The mounting is now complete. The installation needs to be tested before using the AM 50. 32/40...
Press the button on the top to start AM 50, see Figure 45 below. AM 50 will now launch on the lowest ventilation setting. Let it run for ½-1 minutes on this setting. Feel if there is mild airflow coming from the grates at the top and listen if it is running.
7 Dismounting, disassembly and disposal 7.1 Dismounting Should the unit need to be dismounted, follow the installation in reverse. WARNING The power must be turned off before dismounting The ventilation unit is dismounted. Electricity connection is disconnected. The internal part is dismounted. The outside part is dismounted.
