    The “flow SC” model provides multistep control by means of the SH2 control unit and the step valves (1, 2 or 3 step valves depending on the humidifier capacity). The SH2 control unit (for wall mounting) processes analog sensor/control signals and uses them to control the step valves. This allows multistep control (1 to 3 steps depending on the humidifier capacity) which improves control accuracy compared to the “flow”...

  • Page 23: Installation

    Usually, the design and dimensioning of the ventilation duct/monobloc as well as the location of the Condair SH2 inside the duct are determined, recorded and set compulsory when planning the entire system. Prior to installation, however, make sure the following criteria have been taken into consideration: –...
  • Page 24 – We recommend to install air filter (quality standard F7 (EU7) or better) before the humidification unit. The operation without air filter or with a filter of lower quality is possible, this can however, depending on the air quality, lead to an increased contamination of the humidifier boxes and thus to a reduction of the performance/lifetime.

  • Page 25: Mounting Process

    4.2.2 Mounting process 1. Fix the mounting brackets “A” to the water tub using one nut M6 and washer for each bracket. Align the water tub to the centre of the duct, then use the spirit level to adjust the water tub to the duct lengthwise and crosswise.
  • Page 26 Hint: With close space conditions we recommend to install the EPDM sealing profile to the vertical supports before installing the supports. Please refer to step 7 for more information. 3. Carefully mount the left “D” and the right vertical support “E” onto the threaded bolts of the water tub, then fix each support with four nuts M6 and washers (do not overtighten the nuts).
  • Page 27 4. Carefully mount the vertical intermediate support(s) “F” (number depending on the unit size) onto the threaded bolts of the water tub, then fix each support with two nuts M6 and washers to the water tub (do not overtighten the nuts) and with a hexagon socket screw M6x12 and a washer to the cross beam.
  • Page 28 5. Fix the front bracket “G” to each vertical support using two hexagon socket screws M6x12 and washers. Important! Before tightening the screws make sure all supports are vertically exactly aligned!
  • Page 29 6. Fix one mounting bracket “H” to each vertical support and intermediate support using a hexagon socket screw M6x12, a nut M6 and a washer (see figure above). Important: With multiple inter- mediate supports all mounting brackets must be mounted to the supports on the same side. The mounting brackets fixed to the outermost supports must be mounted always outside (between duct wall and support) and point inward.
  • Page 30 7 . The air gap between the outermost vertical supports and the duct walls as well as between the front bracket and the duct ceiling must be sealed using EPDM sealing profile (accessory). Cut the EPDM sealing profiles to the desired length (channel height and channel width plus 5 cm allowance).
  • Page 31 8. Fix hydraulic unit to the water tub and the cross beam using four hexagon socket screws M6x12 and washers. Important: Remove the closing plug “H” from the circulation pump inlet before mounting the hydraulic units REflow, REflow C or REflow SC.
  • Page 32 flow REflow C flow C REflow REflow SC flow SC remains open Important: Insert the hose at least 20–30 mm into the opening! 9. Assemble the drains according to the corresponding figure above (the drains can be assembled for draining to the right or to the left) and fix it to the connector(s) of the water tub. Fasten all threaded connections and hose clamps and fix the drain pipe to the water tub with the pipe sup- port supplied.
  • Page 33 10. Starting from the bottom, install the humidification boxes in each row: Hook the mounting clips of the boxes into the corresponding openings of the supports, then push the humidification box downwards until it comes to a stop (arrangement of the humidification boxes according to the installation drawing included in the delivery).
  • Page 34 11. Only for units with mist eliminator: Hook the mounting brackets into corresponding openings of the vertical supports, then push the brackets downwards until it comes to a stop (if necessary use a rubber mallet). Note: arrangement of the mounting brackets according to the detail figures above and the instal- lation drawing included in the delivery.
  • Page 35 12. Only for units with mist eliminator: Starting from the bottom, install the mist eliminator in each row: Hook the mounting clips of the mist eliminator into the corresponding openings of the mounting brackets, then push the mist eliminator downwards until it comes to a stop. Note: arrangement of the mist eliminator according to the installation drawing included in the delivery.
  • Page 36 13. Mounting the trickling hoods: Push the two tongues on the back side of the trickling hood under- neath the frame sheet of the humidification box (see detail above), then flap the trickling hood downwards. The two brackets on the front side of the trickling hood must engage in the frame (see detail above) of the humidification box.
  • Page 37 Remove the closing plugs from the connections of the hydraulic unit. Cut the water hoses to the required length. Connect water hoses to the connectors on the trickling hoods and the volume controlling valves and fix them with the hose clamps. Note: arrangement of the water hoses according to the installation drawing included in the de- livery.
