Options

Precision
Provides capability of humidifier to achieve ± 1% humidity control*. Solid State Relays allow for rapid response upon call for humidity, adapting rapidly to humidity demand. This allows for quick response and tight control of humidity. Also supplied are two fill valves for quicker response (turbo mode).

• Humidity control is dependent on a variety of factors, including design of piping from humidifier to distributor, duct characteristics from distributor to space, control devices and location. In-field results may vary. Relative humidity levels in the supply duct will vary greater than in-space tolerance levels.
  Scale tank
  Provides a separate reservoir underneath the steam cylinder for scale collection. The addition of this option reduces maintenance time significantly. Minerals removed from the water during steam production will collect in the scale reservoir rather than in the tank. For the double tank humidifiers (RS 135 and 180), order two for each humidifier.
  Built-on Blower Pack
  For direct dispersion into a conditioned environment.
  Remote operating and fault indication
  PCB with relay contacts for the connection of remote displays for “Operation”, “Steam”, “Fault” and “Service”.
  Accessory Board
  PCB with relay contacts for the connection of remote fan enable (cylinder A/B) as well as hygiene flush (cylinder A/B).
  BACnet MSTP BTL
  PCB to provide BTL certified BACnet MSTP. This option also enables full Master functionality when using BACnet MSTP.
  BACnet IP BTL
  PCB to provide BTL certified BACnet IP.
  LonWorks board
  Supplementary board to connect the Condair RS to a building management system via LonWorks.
  Mounting bars
  Provides two mounting bars which fit into each other for wall mounting. One bar is fastened to the humidifier, the other bar is fastened to the wall. The unit can then be “hung” onto the wall by engaging the two mounting bars.
  Note: without this option, the unit may still be wall mounted using the keyhole cutouts on the back of humidifier housing.

Mounting and Installation Work 19

The installation site of the Condair RS depends largely on the location of the steam distributor/blower

pack (see Section 5.4.3 and Section 5.4.4).

To ensure proper

functioning of

the

stoteoabmtahinumanidiofipetriamnadl efficiency, the following points must be considered and observed when choosing

the location for the steam humidifier:

­ Install the steam humidifier so that:

­ the length of the steam line is kept as short as possible,

­ the minimum bend radius for steam hoses (R= 12″ / 300 mm) and for solid steam pipes (5 x internal diameter)

­ the minimum upslope 10° and downslope 2° of the steam hose is maintained. ­ For details of mounting the Condair RS, refer toSection 5.3.2 .

CAUTION!

Do not mount the steam humidifier directly to the ventilation duct.
­ The back panel of the Condair RS retains heat during operation (max. surface temperature of the metal housing approx. 140 – 158 °F / 60 – 70 °C). Make sure, therefore, that the construction (wall, pillar, etc.) to which the unit is to be mounted, does not consist of heat-sensitive material.
­ Install the Condair RS in such a manner that it is freely accessible with sufficient space available for maintenance purposes. The minimum distances shown in the adjacent illustration must be maintained.
­ As a safeguard, the humidifier should be installed in a drip-proof location. Admissible ambient conditions must be complied with.
­ Do not mount the Condair RS to hot or very cold walls or near vibrating components.
­ The steam humidifier Condair RS must only be installed in rooms with a floor drain.
CAUTION!
If for some reason the Condair RS must be installed in a location without floor drain, it is mandatory to provide a leakage monitoring device to safely interrupt the water supply in case of ­ Wlehaeknagmeo.unting the Condair RS use only the mounting materials supplied with the unit. If mount- ing with the materials supplied is not possible in your particular case, select a method of mounting that is of similar stability.
­ The Condair RS is designed for installation and operation within buildings (admissible temperature range 41… 104 °F / 5…40 °C). For outdoor operation the Condair RS must be placed in a weather protective housing. If ambient temperatures near or below the freezing point have to be expected, the protective housing must be equipped with a thermostat controlled heating of sufficient capacity. The water supply pipe must be equipped with heat-tracing and must be insulated up to the protec- tive housing. For outdoor operation, the Keep Warm function must be enabled. The installation of a normally open valve inside the building envelope that will drain water in case of power failure is highly recommended.

5.4.4 Positioning and Mounting the Blower Packs

The blower packs can either be mounted directly on the humidifier or separately above the humidifier to the wall. To allow the steam coming from the blower pack to spread out evenly, without condensing on obstacles (ceilings, joists, pillars, etc.), the following minimum dimensions must be observed when selecting the location for the blower pack. Even small objects that encroach into the steam distribution area may create condensation and reduce efficiency.

Note: Sound measurement at low speed: 57.4 dB; high speed: 64.1 dB taken 3 ft (1 m) from the blower pack.
Note: The minimum spaces in the table apply for a room atmosphere of 72ºF (21ºC), and max 40% RH. For lower temperatures and/or higher humidity the clearance values will increase, and should be adjusted accordingly.
Note: In order to achieve a uniform distribution of the humidity within the room, additional factors such as the room size, the room height, etc., must be taken into consideration besides observing the minimum distances for the blower packs. If you have questions concerning the direct room humidification, please contact your Condair representative.
Further information is provided in the separate installation and operating instructions for the corresponding blower pack.

5.4.5 Installing the Steam and Condensate lines
Installations notes
­ Use original steam and condensate hose from your Condair representative or solid steam pipes from copper (MED-L) or stainless steel (min. AISI 304) exclusively. Steam and condensate lines of other material may cause undesired operational malfunctions. For installations with reverse osmosis or de-ionized water supply, do not use copper steam lines.
­ Initially, lead the steam line upright upwards min. 12″ (300 mm) above the humidifier. Then lead the steam line with a minimum upslope of 10° and/or a minimum downslope of of 2° to the steam distributor.
­ The condensate hose from the steam distributor is led down to the humidifier with a minimum downslope of 1.2°, via a condensate trap (min. hose bend diameter Ø8″ (ø200 mm)) and there it is to be connected to the appropriate connector on top of the unit. Important! Before putting the unit into operation, the condensate trap of the condensate hose must be filled with water.
­ The steam line should be kept as short as possible, as per Table 1 on page 31. Ensure the the minimum bend radii are observed: 12″ (300 mm) for steam hoses or 5x internal diameter for solid pipes. Important! Allowance must be made for a pressure loss from elbows, according to equivalent length tables.
­ Important! When deciding on the length and layout of steam hoses, it should be noted that steam hoses may become shorter and/or longer depending on temperature and age.
­ The steam hose must be secured to the steam distributor and humidifier steam outlet by means of hose clamps. Solid steam pipes should be connected to the steam distributor and steam humidifier with short lengths of steam hose secured with hose clamps. Caution! Do not overtighten the hose clamp on the steam connector of the steam humidifier.
­ Steam lines made of solid pipes (copper or stainless steel) must be insulated over the entire length to minimize condensate formation. Condensate created due to thermal loss in steam lines will reduce the operational efficiency of the humidification system and reduce the moisture supply to the conditioned environment.

30 Mounting and Installation Work

2582419-F EN 2406

DANGER!
Reducing the cross section or the complete closure of the steam line will cause an excessive increase in pressure in the steam cylinder when the unit is operating and could lead to the risk of scalding accidents. All installations must comply with the following instructions.
­ When installing, make sure the steam line is open over the entire length and through the whole cross section. Any sealing plugs, adhesive sealing sheets etc. must be removed before connecting the steam pipe. Reductions in cross section by kinking or crushing must be avoided.
­ Steam hoses must be prevented from sagging (condensate pockets); if necessary, support steam hose with pipe clamps, trough, or wall brackets, and install a condensate drain at any low points in the steam line.
­ It is not permitted to install a stop valve (e.g. a manually controlled isolation valve, solenoid valve, etc.) in the steam line, due to an inadmissible increase of pressure in the steam cylinder if the valve is closed during the operation.

Notes: The use of steam line other than copper, stainless steel tube, or Condair supplied steam line will void the warranty and may adversely affect the operation of the humidifier. Long steam runs affect accuracy of humidifier and its ability to quickly respond to changes in demand. When tight control is required, ensure steam line run is as short as possible. Steam line per boiling tank. Do not combine steam lines except at distributor using a Condair adapter designed for that purpose and only if humidifiers operate in parallel.

5.6.3 Notes on Water Installation

5.6.3.1 Water Supply (Potable, RO or DI water)

The water supply is to be carried out according to Fig. 17 and Fig. 18 or Fig. 19 and Fig. 20 and the applicable local regulations for water installations. The indicated connection specifications must be observed.
­ The installation of a filter valve (alternatively a shut-off valve and a 5 micron water filter can be used) should be made as close as possible to the steam humidifier.
­ Admissible mains pressure 30 … 80 psi (2.1…5.5 bar) For mains pressures > 145.0 psi (>10 bar), the connection must be made via a pressure reducing valve (adjusted to 30.0 psi (2.1 bar)). For mains pressures <30.0 psi (2.1 bar) please contact your Condair supplier.
Note: The water supply system must be free of pressure bumps (hammer-free). The installation of a check valve in the water supply line is therefore not permitted, as this can lead to pressure bumps in the water system and damage the inlet valve. If a pipe disconnector is to be installed in the inlet water system, a model with overpressure protection must be installed. If water hammers cannot be avoided in the supply line, a pressure shock absorber must be installed.
­ Supply rates:

RS Small Medium Large

Max. fill rates 3.70 gal/min (14 l/min) 3.70 gal/min (14 l/min) 2 x 3.70 gal/min (2 x 14 l/min)

­ Notes on water quality:
­ For the water supply of the Condair RS, use exclusively potable drinking water in accordance with the applicable local regulations or water from a RO system or de-ionized water system.
­ The use of additives such as corrosion inhibitors, disinfectants, etc. is not allowed, since these additives may endanger health and affect proper operation.
­ Conductivity should be between 1 and 1500 S/cm. Note that conductivity less than 1 S/cm is very aggressive water (this is equivalent to a resistivity of 1 M or greater). It is recommended to blend such water with other less-treated water to ensure the supply is not overly aggressive.
­ Hardness should be between 0 and 12 grains/gallon.
­ Silica content should be between 0 and 12 ppm.
­ pH should be between 6.5 and 7.5.
­ Chloride content should be between 0 and 50 ppm.
­ The connection material must be pressure-proof and certified for use in drinking water systems. When connected to a RO or DI water source, use only installation materials that are acceptable for the treated water.
­ Important! Before connecting the water line(s), the line(s) must be well flushed out.

CAUTION!
The thread at the humidifier connection is made of plastic. To avoid overtightening, the adapter and the union nut of the water pipe must be tightened by hand only.

5.6.3.2 Additional Requirements for RS-RO Option Water Supply

With the RS-RO option installed the water supply and the drain cooling water supply are to be carried out according to Fig. 19 and Fig. 20 and the applicable local regulations for water installations. The indicated connection specifications must be observed.
­ RO water supply:
­ The RO water supply must be connected to the inlet connector(s) according to Fig. 19 and Fig. 20. Use only installation material that is approved for RO or DI water to connect the RO-A pure water system to the Condair RS. All water supply requirements outlined in Section 5.6.3m.1ust also be adhered to with the RO or DI water supply.
Note: Detailed information regarding the installation of the RO-A pure water system can be found in the separate installation and operation manual of the Condair RO-A.
­ Drain cooling water supply:
The seperate drain cooling water supply must be connected to the optional drain water cooling inlet valve(s) provided with the RS-RO option according to Fig. 19 and Fig. 20. Please observe the following notes regarding the drain cooling water supply installation.
­ Admissible mains pressure 30 … 80 psi (2.1…5.5 bar) For mains pressures > 145.0 psi (>10 bar), the connection must be made via a pressure reducing valve (adjusted to 30.0 psi (2.1 bar)). For mains pressures <30.0 psi (2.1 bar) please contact your Condair supplier.
Note: The water supply system must be free of pressure bumps (hammer-free). The installation of a check valve in the water supply line is therefore not permitted, as this can lead to pressure bumps in the water system and damage the inlet valve. If a pipe disconnector is to be installed in the inlet water system, a model with overpressure protection must be installed. If water hammers cannot be avoided in the supply line, a pressure shock absorber must be installed.
­ Supply rates:

Fig. 21: System Setup Schematic 1 Humidistat 2 Humidity sensor 3 High limit humidistat 4 Air proving switch
Notes: · Locate the air proving switch in the same duct as the humidifier’s distributor so that it can sense air
flow (or lack thereof). · Locate the high limit humidistat downstream of the humidifier’s distributor so that it can sense a duct
that is over-humidified. Recommended setting is 85% RH. Locate it downstream of the distributor at least 5x the absorption distance. If the absorption distance is not known, locate at least 10 feet (3m) downstream of the distributor. Can be a humidistat (modulating or On/Off), or a humidity sensor. · Humidity sensors and humidistats can be modulating or On/Off. Preferred location is in the return duct, as the supply air is well mixed with the room air at this location. Avoid placing near discharge diffuser, near doorways, in sunlight, or in airflow “dead-zones”.
