3.5.2 System overview model “flow SC”
Shut-off valve
Functional description
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” model.
In case of a humidification/cooling request one, two or all three step valves open (depending on the request). The water flows via the manually adjustable volume controlling valves to the distribution pipes above the humidification boxes.
The distribution pipes evenly supply the water to the entire surface of the humidification boxes where it flows down and humidifies the air flowing through the humidification boxes. The excess water not used for humidification flows to the water tub and then directly to the drain.
If the “flow SC” model is equipped with the optional UV water treatment (installed in the water supply) the water is continuously degerminated during the humidification process.

3.6.2 System overview model “REflow”
Functional description
The water tub is filled up to a preset upper level via the level-controlled supply valve. When the water level in the tub drops below a certain limit, the level-controlled supply valve opens until the upper limit is reached again.
In case of a humidification/cooling request the circulation pump starts and supplies the water via the manually adjustable volume controlling valves to the distribution pipes above the humidification boxes.
The distribution pipes evenly supply the water to the entire surface of the humidification boxes where it flows down and humidifies the air flowing through the humidification boxes. The excess water not used for humidification flows to the water tub and is fed back to the circulation pump.
To prevent accumulation of mineral residues in the water tub, a limited amount of water is continu­ously drained via a manually adjustable volume controlling valve and replaced with fresh water.

4 Installation
4.1 Important notes on the mounting and installation work
Qualification of personnel
All mounting and installation work must be carried out only by well qualified personnel authorised by the owner. It is the owner’s responsibility to verify proper qualification of the personnel.
General note
Strictly observe and comply with all information given in the present installation and operat­ing instructions regarding the mounting of the unit and the installation of water and electricity.
Observe and comply with all local regulations dealing with water and electrical installations.
Safety
The electrical installation for the unit models flow C, flow SC, REflow C and REflow SC requires the removal of the control unit cover. Please note the following:
DANGER! Danger of electric shock!
You may get in touch with live parts when the control unit is open. The control unit must be connected to the mains only after all mounting and installation work has been completed and the control unit cover has been relocated properly.
CAUTION!
The electronic components inside the control unit are very sensitive to electrostatic discharge. When the unit is open for installation work, appropriate measures must be taken to protect these components against damage caused by electrostatic dis­charge (ESD protection).
4.2 Unit mounting
4.2.1 Note on locating the unit
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:
– For operation with fully demineralised water: Fully demineralised water is aggressive! For this
reason, all components located close to the humidification unit (duct/monobloc, fastening mate­rial, drain pipe, etc.) must be made of corrosion-proof steel (minimum requirements according to DIN 1.4301) or plastic.
– For installation and maintenance of the humidification unit a viewing window and a sufficiently
large maintenance door (min. width= installation depth Condair SH2, see chapter 9.2) must be available in the duct/monobloc.
– In the area of the humidification unit the ventilation duct/monobloc must be waterproof.
– In the area of the humidification unit the duct floor must offer a plane support (plane duct floor or
profile construction), which is lengthwise and crosswise horizontal aligned and has a sufficient load-bearing capacity to support the humidifier unit.
Page 24
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.
– In case of low ambient temperature the duct must be insulated to prevent the moist air from
condensing inside the duct.
– If the system is equipped with a heater, make sure it is at least 0.5 m away from the humidifica-
tion unit.
– If silencers are mounted in the airconditioning units make sure to locate the humidification unit
at a minimum distance of 3 m before or after the silencers.
– In order to avoid drops seeping over the humidification boxes, an even air flow over the full cross
section of the humidification unit must be guaranteed. If necessary, rectifiers or perforated plates must be installed on the building side before the humidifier. If the air velocity above the humidification boxes exceeds 3.8 m/s, mist eliminator must be in­stalled.
– The effective height of the siphon in the drain line depends on the duct pressure. Correct dimen-
sioning of the siphon is the customer’s responsibility.

4.2.2 Mounting process
1. Fix the two 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. When adjusted, fix the mounting brackets to the duct wall using two self-tapping screws 5.5x19.
Note: Alternatively the water tub can be fixed directly to the duct floor/support construction with four self-tapping screws 5.5x19 on each side.
2. Fix the cross beam “B” to the water tub using four hexagon socket screws M6x12 and washers.

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 inter­mediate 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. Finally align the supports, then fix the mounting brackets to the duct ceiling using two self-tapping screws 5.5x19 each.
Page 30
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). Fix the EPDM sealing profiles to the outermost vertical supports and to the front bracket using the clamping brackets and self-tapping screws 5.5x19 supplied. Tailor the EPDM sealing profiles to the duct height and the duct width, then fix them to the duct walls and the duct ceiling using the clamping brackets and self-tapping screws 5.5x19 supplied (number of self-tapping screws to be used as required). Note: In place of the EPDM sealing profiles also sheet metal angles of stainless steel (not included in the delivery) may be used for the sealing.

6 Maintenance
Qualification of personnel
All maintenance work must be carried out only by well qualified and trained personnel authorised by the owner. It is the owner’s responsibility to verify proper qualification of the personnel.
General note
The instructions and details for maintenance work must be followed and upheld.
Only the maintenance work described in this documentation may be carried out.
Only use original Condair spare parts to replace faulty parts.
Safety
Before carrying out any maintenance work take the Condair SH2 out of operation as described in chapter 5.4 and secure the unit against inadvertent power-up. In addition the take ventilation
system out of operation as described in the operations instructions of the ventilation system and secure the ventilation system against inadvertent power-up.
The Condair SH2 must be maintained in the prescribed intervals, the cleaning work must be carried out correctly and the humidification boxes and the mist eliminator boxes must be replaced after their prescribed lifetime has elapsed.
WARNING!
If the unit is insufficient maintained ill-making germs may grow in the water tub and the humidi­fication boxes (and the mist eliminator) of the Condair SH2 and may can affect the air passing through the humidifier.
6.1 Important notes on maintenance
Page 51
51
6.2 Maintenance intervals
In order to maintain operational safety the Condair SH2 must be maintained in regular intervals. The time interval for the maintenance is to be adapted to the operating conditions. The hygiene status depends mainly on the quality of the humidifier water but also on the adherence to the exchange intervals of the upstream air filter, the air velocity and the micro-biological and chemical composi­tion of the supply air. Therefore the maintenance intervals must be determined for each system separately. The first maintenance must be carried out after 800 operating hours. Depending on the encountered hygiene status during the first maintenance the interval time must be decreased or increased.
In any case the Condair SH2 is to be maintained however at least twice annually.
On units equipped with a SH2 control unit (flow SC, REflow C and REflow SC) the maintenance interval can be programmed. As soon as the maintenance time has elapsed, a maintenance mes­sage is displayed to draw your attention to the pending maintenance. To determine the maintenance interval time the above described procedure can be used.
6.3 Maintenance work
