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
IMPORTANT: Drain line must be trapped under the unit to prevent flash steam from
condensing in the unit cabinet, as seen in figure 3.h.2.

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.
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.
3.3.5 Condensate Pump
When using a Condensate Pump, ensure pump selected is capable of handling 7.0 GPM for up to 10-15 seconds.

3.4 Steam distribution

3.4.1 Duct steam injection (Additional kit required)
The maximum allowed duct static pressure is 2 in WC.
