Water Supply Line
– The water supply must be installed to local plumbing codes.
– In cold climates make sure that an external freeze protection system (utilizing either a normally-open
and a normally-closed valve, or a 3-way normally-closed valve – supplied by others) is installed
inside the building to protect the water supply line from freezing. Refer to
"External Freeze Protection
System" on page 35 .
IMPORTANT!
The warranty does not cover damage to the humidifier resulting from freezing.
– For ease of maintenance, make sure that a water shutoff valve and union fitting are installed in the
supply line (inside the building), as close as possible to the humidifier.
– The water filter (optional, but recommended) must be installed on the inside of the building as close
as possible to the humidifier.
– The water supply line should be minimum 1/2 in (13 mm) in diameter, and have a 1/2 in NPT female
end.
– Route the water supply line through a pipe chase to the unit. In cold climates, install trace heating
and insulation to prevent the line from freezing.
CAUTION!
Risk of damage to the plastic threads of the fill valve!
Prevention: Hand-tighten the NPT adaptor to the fill valve.
– Install the NPT adaptor and O-ring (supplied) on the fill valve and hand-tighten. Connect the water
supply line to the adaptor.
Drain Lines
– Make sure that the air gap funnel is located inside the building, and connected to a dedicated building
drain (recommended) with a drainage capacity of at least 2.3 gpm (8.7 L/min) for an EL-OC unit and
6.7 gpm (30 L/min) for a RS-OC unit – per steam cylinder. The drain line exiting the funnel should
be minimum 7/8 in (22 mm) in diameter for an EL-OC unit, and minimum 1-3/4 in (45 mm) for a
RS-OC unit. In large units, separate air gap funnels must be used for drain lines from each cylinder.
– All drain lines described below should be as short as possible, and routed through a pipe chase.
Drain lines must have a constant minimum downslope of 1 in/48 in (1.2°) and empty into the funnel
