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.
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.
Page 31
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.

– 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.
20. Use only installation material that is approved for RO or DI water to connect the RO-E pure water system to the Condair RS. All water supply requirements outlined in Section 5.6.3.1 must also be adhered to with the RO or DI water supply.
– The draining temperature is 140 °F (60°C) or less. Use temperature-resistant installation materials only! – When operating the Condair RS with RO water use only installation material that is approved for RO water. – Make sure that the drain pipes, the funnel(s) and the siphon(s) are correctly fixed and easily acces- sible for inspections and cleaning purposes.

Has the heat resistance of the material used been verified to be at least 212 °F/100 °C (140 °F/60 °C for systems with optional drain water cooling)? If the Condair RS is operated with RO or DI water: Has installation material been used approved for the treated water? Is/are the drain hose(s) properly secured (hose clamps at unit connection tightened)? Is there an air gap (min.
Notes on Humidity Control Systems/Humidity Control 5.7.1 Control Device Locations The following schematic describes a potential system setup with respect to control devices. Fig. 21: System Setup Schematic Humidistat Humidity sensor High limit humidistat 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).
DANGER! Danger of electric shock The Condair RS is mains powered. Live parts may be exposed when the unit is open. Touching live parts may cause severe injury or danger to life. Prevention: The Condair RS unit must be connected to the mains only after all mounting and instal- lation work has been completed, all installations have been checked for correct workmanship and the unit is closed and properly locked.
