– Route a drain line (supplied by others) with an inside diameter of 1-3/16 in (30 mm) through the
large hole in the bottom panel and connect it to the flexible bent hose (supplied) exiting the humidi-
fier – refer to
Figure 14 on page 32
. Secure the line with clamps (supplied). Route the other end of
the drain line to the air gap funnel.
– Route the 3/8 in (9.5 mm) I.D. drain hose from the mechanical freeze protection valve (and scale
tank in RS-OC units) through the small hole in the bottom panel to the air gap funnel, as shown.
– In cold climates, install trace heating and insulation to prevent the drain lines from freezing.
– All drain lines must be installed to local plumbing codes.
Upon completion of the water and drain connections, perform the following:
– To ensure that the IP54 rating of the unit is maintained, seal all gaps around the drain lines where
they pass through the bottom panel in the unit.
IMPORTANT! Seal all pipe chases to prevent any rising steam from entering the bottom of the
unit, and to isolate the unit from the pressure inside the building.
– Disconnect and flush the water supply and drain lines to clear out any debris in the lines. Check
the strainer in the fill valve to ensure it is clear of all debris (refer to the Nortec EL/RS manuals for
details). Reconnect the lines.
