Description
The Condair HumiLife RH is a residential steam humidifier designed by Condair. It is designed to
provide steady, clean humidification for the home, and is designed to connect to a supply air duct. The
humidifier may be mounted directly onto the duct, or remotely with connected steam hoses and
distributor.
Figure 2 - RH Humidifier Duct and Remote Installations
Principle of Operation
The Condair HumiLife RH is an atmospheric steam generator that uses heat generated by an electrical
current flowing between submerged electrodes to generate steam.
VAC
L1
L2
L1: higher amp draw when
more of the electrode is
submerged
L2: lower amp draw when
volume of water decreases
Figure 3 - Principle of Operation
Increasing the water level submerges the electrodes. This increases the current draw at the electrodes.
Increasing the concentration of minerals in the water increases the current draw of the electrodes.
Increasing the current draw increases steam production.
High concentration of minerals in the water over time forms scale on the electrodes. This reduces the
effective area for the electrodes and reduces steam output. To maintain the desired current draw, the
cylinder automatically fills with water (submerging more of the electrode), or allows the water to boil off.

Installing the Steam Distributor
The Condair HumiLife RH can be installed directly onto the duct system or remotely, with the installation
of a steam distributor (including steam lines) to the duct. The installation of the steam distributor (and
steam line) will determine the appropriate location for mounting the humidifier.
Condensate returns to the unit via steam line. In some cases, a separate condensate line from the
steam distributor may be required. The condensate line would connect to the top of the fill cup inside
the unit, or to a high temperature condensate pump.
Location and Clearances (remote installation)
Vertical ducts:
lPlace the steam distributor half-way between sides of the duct. Ensure the air flow and the
steam distributor openings are directed upwards.
lMinimum duct width: 8 in (204 mm).
Horizontal ducts:
The steam distributor can be installed on the side of the duct.
lWhen installed at the side of the duct, ensure that the distributor is located at least 2/3 duct-
height from the top.
lMinimum duct height: 8 in (204 mm).

≥ 8 in (204 mm)
Installing the Steam Distributor:
1. Find a suitable location for the steam distributor. Create a 1.18 in (30 mm) hole in the duct.
lFor horizontal ducts, cut the hole at roughly 2/3 of duct height, from the top.
lFor vertical ducts, cut the hole halfway between the two sides of the duct.
2. Place a gasket (supplied) over the steam distributor and insert the distributor into the duct.
Ensure the gasket is placed between the distributor and duct, and ensure that the arrows on the
distributor are pointing up. Secure the distributor to the duct with self-tapping screws.
