Page 11: Installation Of The Humidification Unit
For safety reasons the Condair DL must be installed only in rooms provided with a floor drain. If for some reason the Condair DL must be installed in a location without floor drain, it is mandatory to provide a water tub with drain below the central unit and the duct wall feed throughs and/or water sensors in the room/water tub to safely interrupt water supply in case of leakage. - Page 12 – For control and maintenance purposes we recommend to provide the duct/AHU with an additional inspection door after the post-evaporation unit. – The section of the duct holding the humidification unit must be equipped with a sloping tub having drains before and after the post-evaporation unit (pass-through tub), or with a drain before the separation as well as drains before and after the post-evaporation unit (separated tubs).

Page 13: Mounting The Post-Evaporation Unit
4.2.2 Mounting the post-evaporation unit 1. Marking the positions of the fastening elements inside the duct/AHU: • Mark the position of the topmost fastening holes (or welding studs) for the fastening of the lateral supports of the post-evaporation unit “A”, the nozzle system “C” and the fastening profiles for the lateral sealing plates “B”... - Page 14 2. Mount the lateral supports of the post-evaporation unit to the duct walls: • Align the lateral supports with the “TOP” labeled mounting bracket on top with an identical dis- tance to the duct ceiling (target measure ”a”: 65 mm, admissible range: 0...90 mm) and with a distance “b”...
- Page 15 3. Mounting the fastening profiles for the upper sealing plates: • If not done already in step 1, mark the position of the outmost fastening holes for the fastening of the leftmost and rightmost fastening profiles for the upper sealing plates “D” on the duct ceiling using the bended drilling template.
- Page 16 4. Mounting the fastening profiles for the lateral sealing plates: • If not done already with the drilling template in step 1, mark the position of the lateral fastening profiles for the lateral sealing plates on both sides of the duct. Distance between fastening profiles and post-evaporation supports 275 mm.
- Page 17 5. Mount the cross members: Note: This step must be carried out only on air ducts /AHU's with a width >1650 mm. • For air ducts/AHU's with a width >2000 mm the cross members are supplied in sections and must be bolted together on site. Proceed as follows: Undo the screw connections on the cross members overlapping.
- Page 18 6. Mount the vertical support(s): Note: This step must be carried out only on air ducts /AHU's with a width >1650 mm. • For air ducts/AHU's with a height >2000 mm the vertical supports are supplied in sections and must be bolted together on site. Proceed as follows: Undo the screw connections on the vertical supports overlapping.
- Page 19 • Mark horizontal position(s) of the vertical support(s) on the cross members (one vertical sup- port is always in the middle of the duct, several vertical supports must be evenly allocated over the duct width). From the front (view in air flow direction) attach the vertical support(s) with the angle bracket on top to the cross members, then shift upwards until it comes to a stop and fix the vertical support(s) four screws M6 x 16 mm and nuts to the cross members.
- Page 20 7. Mounting the lateral sealing plates: • Start on the bottom shift the lateral sealing plates with the slightly bent surface behind the fasten- ing profiles. Make sure the sealing plates on top of each other covers and overlaps the subjacent sealing plate.
- Page 21 8. Inserting ceramic support profiles: • Insert the ceramic support profiles into the lowest row of holders. Make sure the support profiles are inserted such that the pins on each side of the support profile are outside of the holder. Abb.
- Page 22 9. Mounting the tub rubber sealing: • Fix tub rubber sealing with the clips to the ceramic support profiles as shown below (longer part of the clip is on the side of the rubber sealing). Cut rubber sealing on both sides of the duct to the appropriate length.
- Page 23 10. Inserting ceramic carrier profiles: • Insert the ceramic carrier profiles into holders. Make sure the carrier profiles are inserted such that the pins on each side of the carrier profile are outside of the holder. Abb. 12: Inserting ceramic carrier profiles Installation...
- Page 24 11. Mount the ceramic plates: • Start from the bottom left (view in air flow direction) carefully hang the ceramic plates of the bot- tom row onto the carrier profiles, then align the row to the middle of the duct. Important: Make sure, the very right and very left ceramic plates have the same distance to the duct wall and that all plates properly rest against each other.
- Page 25 12. Mount the upper sealing plates: • Starting on one side push the upper sealing plates underneath the fastening profiles until the they touch the ceramic plates of the topmost row. • Carefully shift the very right and the very left sealing plate against the lateral sealing plates without pushing them away.

Mount the cross members: Note: this step must be carried out only on systems with two nozzle grids in the width. • For air ducts/AHU's with a width >2000 mm the cross members are supplied in sections and must be bolted together on site. Proceed as follows: Undo the screw connections on the cross members overlapping.
- Page 28 3. Mount vertical support(s): Note: This step must be carried out only on air ducts /AHU's with a width >2000 mm. • Mark horizontal position(s) of the vertical support(s) on the cross members. From the back (view in air flow direction) attach the vertical support(s) with the same distance to the duct ceiling as the lateral supports of the nozzle system have, then fix the vertical support(s) four screws M6 x 16 mm and nuts to the cross members.
- Page 29 4. Hang up nozzle grid(s): • Hang up nozzle grid into the holders, then push nozzle grid downwards until its comes to a stop. Repeat step for additional nozzle grid(s) if necessary. Abb. 18: Hang up nozzle grid Installation...
- Page 30 5. Mount housing feed throughs: • Drill holes ø19 mm for the housing feed throughs at the desired position (distance between axes min. 55 mm) into the duct wall, then deburr the holes. Important: It is mandatory that the holes of the housing lead-throughs are below the lowest hose connector on the nozzle grid(s).
- Page 31 6. Connect spray circuits to the housing feed throughs: • Interconnect the spray circuits of the different nozzle grids (if more than on grid is present). Interconnect spray circuits with same colour only. • Connect spray circuits to the appropriate housing feed throughs. Spray circuit 4 (green) Spray circuit 3 (yellow) Spray circuit 2 (blue)
