3.3 Fitting the humidifier For the fitting of the humidifier use the material supplied with the unit. Observe the various minimum distances as indicated in figure 3.5. Ensure that there is sufficient room to perform servicing and maintenance work and that the unit is easily accessible. To facilitate such work, mount the unit at eye level. We recommend that the unit is installed as near as possible to the steam-distribution pipe. The highest degree of efficiency is attained when the humidifier

Steam-distribution pipe fitted on suction side: Because of the under-pressure in the appliance or the duct part, condensate may be kept back in the steam-distribution pipe. If there is an outlet in the empty part of the humidifier, the condensate can be bled off in the immediate vicinity. An alternative method of bleeding off the condensate can be seen in the diagram.

3.7 Laying the condensate hose It is advisable to lay the condensate hose as near to the ver- tical as possible and to feed the condensate either directly into an open funnel or below the siphon. Condensate If the steam-distribution pipe is fitted above the humidifier, the fed back to condensate can be fed back to the unit by placing the end of the the unit hose in the filling cup. In this case a small siphon should be for- med with the condensate hose. If the condensate is drained off directly

4.2 Water intake and drainage Please observe the local regulations concerning the connection of appliances to the pressure and drainage system. The humidifier is designed to operate on ordinary tap water only. If you intend to use treated or de-mineralised water, consult your NORDMANN representative beforehand. Where the water pressure is between 1 and 10 bar (0.1–1 MPa) the unit can be connected directly to the water supply. If it is over 10 bar (1 MPa), connection must be made via a pressure

6 Putting the humidifier into operation 6.1 Start-up Prior to starting the unit up, check the correct connections of the steam pipe, water feed pipe, drainage pipes and electrical cables. Open the shut-off valve in the water feed pipe and switch the unit on with the black power switch. As soon as the demand for steam is recognised, the green LED lights up, the contactor is activated and , soon after, water is let into the steam cylinder. As soon as the electrodes in the cylinder are covered wi

7 Maintenance Regular servicing helps to maintain the operation of the humidifier. The following work must be carried out by qualified personnel. ! 7.1 Regular checks • Inspect the steam cylinder: Are there any deposits in the steam cylinder? ⇒ Remove the drainage strainer and flush the cylinder thoroughly with tap water (without chemical additives). Replace the strainer after cleaning. • Are the electrodes worn? ⇒ Replace the steam cylinder. • Inspect all hoses (steam-, condensate- and water ho
