3.3.3 Water Drain
The Elite Steam also requires a connection to a drain. The drain line may be routed out the
back or bottom of the unit using the included angle fitting. The drain line can be 1-1/4” PVC,
CPVC or polypropylene. The drain line is not glued or otherwise attached to the humidifier so
it must be supported by itself. A coupling should be used. The Elite Steam includes a drain
tempering valve that runs whenever the drain pump runs and flushes cool water into the drain
line to insure the drain water temperature never exceeds 60°C or 140°F.
The drain water characteristics are:
 Drain Flow Rate – See Technical Specifications (Section 8 / pg 24)
 Connection 32mm or 1 1/4”
 Temperature 60°C or 140°F
NOTE: Drain line must be trapped under the unit to prevent flash steam from condensing in
the unit cabinet.
3.3.4 Drain Connections
When using a rear outlet drain passing through drywall, we suggest using a 1 1/4” extension tube type SJ (see Fig. 3.f).
When using a bottom outlet drain, attach the included 90° fitting to the drain outlet. The drain outlet may be rotated. Then
connect a 1 1/4” trap adaptor to connect to drain pipe.
IMPORTANT WARNING: The drain pipe must be free without back pressure. We recommend an external anti-flooding
device not supplied to protect from faults of external hydraulic circuits.
3.4 Steam distribution
3.4.1 Duct steam injection ( Additional kit required)
The maximum allowed duct static pressure is 2 in WC.
The Elite Steam duct injection models include a plastic duct injection nozzle. See Fig. 3.i
