Drain Connection - Elsteam KT Operator's Manual

KT Electrodes Humidifiers
1. If the air duct can be drained from the bottom, install the steam distributor in the air duct
with the nozzles down and open the end of the steam distributor removing the plastic plug:
the condensate steam goes in the drain of the air duct.
2. If it's difficult to drain the water from the air duct, install the steam distributor with the
nozzles at the top and drain the condensate steam from the lowest side of the steam
distributor through a small siphon soldered at the bottom of the distributor itself. (see
draw).

1.13 Drain connection

The drain system must be capable of handling ten litres discharge in few seconds, without opposing
counter pressure to the humidifier drain.
The Elsteam humidifier is able to remove the limestone concentrated in the boiler only if the
external drain plumbing is totally free:
- pipe internal diameter not less than 40 mm
- pipe must be vertical, without sharp bends
- the drain of the humidifier must be separate from any other drain. The boiler is
directly connected to the drain system through a syphon: if the drain creates
a vacuum depression, it sucks the water from the humidifier, with an efficiency loss or a lack of
production.
In any case, Elsteam suggests to install a collecting vessel, preferably opened to the atmosphere,
of, al least, 10 litres. If the drain system is made of material, which conducts electricity, it should
be earthed.
