3 Installation of Air Units
Attic Units a² and a³
1. Pull out the spigots 1. Never lift the unit into the spigots, as it can damage the unit.*
2. Turn the spigots around and mount them using the included tapping screws (for power drill,
use lowest torque setting).
3. Make a platform
4. Allow for 60 cm free space in front of unit, to assure service access.
5. Make sure the unit is mounted with a minor backward fall.
6. A siphon 5 must always be installed with the unit (to be ordered separately).
7. Mount the siphon on the joist
8. Connect the siphon to a drain 6.
9. The condensate line 3 must be insulated where risk of freezing occurs.
10. Connect the hose to the unit outlet condensate spigot. Lead the connected pipe to the outlet, allowing for a gradient of min. 1 cm/metre.
11. Remove the front panel and foam front, fill the condensate tray, check the outlet and reassemble the front.
* If the unit is lifted into the spigots, it might cause leakage between the steel cabinet and the polystyrene core. The leakage can be fixed from the inside of the unit by sealing the spigots with an acrylicbased sealant.
for the unit of 16 mm plywood or MDF sheet around 50 mm wall batts.
below the unit or in the room below the attic.
Wall Units w¹ and w²
1. Place the mounting bracket 1 on the wall in desired position (75 mm from bracket bottom to
unit top), mark up and drill holes. Use screws suitable for the wall surface (not included).
2. Make sure that the bracket is mounted absolutely horizontal.
3. Hang the unit onto the bracket.
4. Attach the self-adhesive rubber separators
to the lower rear back plate.
5. Allow for 60 cm free space in front of unit, to assure service access.
6. A siphon
must always be installed with the unit (to be ordered separately).
7. Mount the siphon on the wall below the unit.
8. Connect the siphon to the drain
at the unit bottom.
9. The condensate line 4 must be insulated where risk of freezing occurs.
10. Connect the hose to the unit outlet condensate spigot. Lead the connected pipe to the outlet, allowing for a gradient of min. 1 cm/metre.
11. Remove the front panel and foam front, fill the condensate tray, check the outlet and reassemble the front.

4.1 Electrical connections
1. Connect power cable 4 to Air unit 3.
2. Plug in communication cable 2 between CCM module 1 and Air unit.
3. Check the signal. If it is too weak, the CCM module should be placed elsewhere, e.g. on the
same floor as as the Air Dial (see Air Dial Link Test).
4. If possible, place the CCM module close to an ethernet connection for future connection to
PC.
5. If accessories (electrical preheating, electrical afterheating, water heating surface or geothermal surface) are present, the pin on terminals 5 and 6 must be removed (also see the
instructions included with the accessories).
Communication cable connections:
1. White/Orange, 2. Orange, 3. Black, 4. White/Blue, 5. Blue, 6. Black
Note! The communication cable can be extended up to 200 m. Use shielded cable , 22 or 24 AWG with 2 x twisted pair.
4.2 Wireless connection
When powering up the CCM module a green LED will flash slowly, indicating the CCM module
has yet to be connected to the Air Dial.
To connect the Air Dial, insert the batteries. The Air Dial starts in installation mode and automatically guides through the set-up.
1. Set language.
2. Create network (press button on CCM module and then press Air Dial).
3. Set basic step (setting up the main air volume).
4. Finish.
Green LED lights continuously Connected established
Red LED flashes slowly 5 times Connection attempt failed, see Troubleshooting.
