Before installation check that the correct OptiSorp system is used and that the system is in accord-
ance with the type and steam output on the specification label.
The OptiSorp is suitable for installation in air ducts or air-conditioning units. For this purpose the tem-
plates supplied are attached to the ventilation duct spaced according to the collectors. The duct plate
is cut out round. The connection side of the pre-fitted system is inserted from inside through these
holes. The connector pieces are then fitted on the pipes from outside and screwed to the duct wall.
The collector pipes should be aligned horizontally and secured at the end on the duct wall.
For large systems or in special cases, where this type of installation is not possible, the collector
pipes can be fitted individually from outside. The nozzle tubes are then inserted in the collectors in
the air duct and secured with the pipe clamps and O-rings. Suitable pliers are required for the instal-
lation. All parts are supplied loose for this case if required.
The steam and condensate hoses should then be installed according to the instructions in the techni-
cal tem. It is advisable to drain the condensate separately and not return it to the humidifier owing
to the increased volume.
1.5 Putting into operation
When connected to several basic units these should be operated in parallel. Otherwise condensate
runs into the units switched off and fills these until overflow occurs. Problems can then arise when
switching on again.
The following should be ensured when putting into operation:
1. that the system pressure don’t increase over 1500 Pa. The system pressure is componed of the
airduct static pressure, the pressure drop over the OptiSorp system (typical 500 Pa) and the back
pressure in the steam hose (typical 100 Pa/m)
2. that no water splashes from the steam distribution system and the condensate runs out of the
system satisfactorily. Condensating formation may be caused by:
• Steam supply pipe not properly drained
• Metallic steam pipe inadequately insulated
• Overstressed steam generator feeds water through steam pipe
• System condensate drain is blocked
• Extreme back-pressure in condensate hose
• Incorrect installation of condensate hose
