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 – Condair 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.

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:

• Place the steam distributor half-way between sides of the duct. Ensure the air flow and the steam distributor openings are directed upwards.
• Minimum duct width: 8 in (204 mm).

Horizontal ducts:
The steam distributor can be installed on the side of the duct.

• When installed at the side of the duct, ensure that the distributor is located at least 2/3 duct height from the top.
• Minimum duct height: 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.
   • For horizontal ducts, cut the hole at roughly 2/3 of duct height, from the top.
   • For 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 steam distributor to the duct with self-tapping screws.

---|---|---

Considerations when installing the steam distributor:

• Do NOT exceed the maximum recommended steam line length, 15 ft (4.5 m).

• Do NOT over tighten hose clamps at the steam outlet. Max torque: 12 in·lbs(1.36 Nm).

• Ensure the steam line material is Condair-supplied, otherwise copper or stainless steel.

• Ensure the steam line out of the humidifier is vertical 6 in (15 cm) min. before any bends.

• Install the steam distributor as close as possible to the humidifier. Short distances minimize condensate losses and reduces the possibility of back pressure in the distribution line.

• Insulate the steam lines to reduce heat loss and condensate. Use 1.0 in (2.5 cm) pipe insulation, rated for 212 °F (100 °C) (recommended).

• Use the appropriate slope for the steam line.
  – The steam line should have a slope greater than 15° (above the horizontal) away from the humidifier for upward traveling steam.
  – The steam line should have a slope greater than 2° (below the horizontal) for downward traveling steam.
  Condensate should be removed from the steam line at low points using  a T-connector condensate trap (not supplied).

• Support the steam line with brackets because the steam hose will soften, and to reduce the weight on the cylinder.

Condensate Line Considerations:

• Use condensate traps wherever condensate may form along the steam line. For example, at low points along the line, at horizontal-vertical transitions, or after long distances.
• P-traps located a minimum of 12 in (30 cm) below the duct.
• P-trap height minimum of 6 in (15 cm), or duct pressure + 2 in (5cm).
• Down slope of 1in/48in (1.2°), minimum.

Mounting the Humidifier

Location and Clearances
Allow clearances required for plumbing and electrical connections. Clearance dimensions shown are for reference only and are the minimum required for maintenance of the humidifier. Consult local and national codes before final location and installation. Condair does not accept responsibility for installation code violations.

• Mount on a suitable wall or vertical surface. Do NOT sit the unit on the floor.
• When possible, mount the humidifier at a height convenient for servicing.
• Install in areas with ambient temperature 40 –104 °F ( 5 – 41 °C) and relative humidity 5 – 95% RH.
• To allow for proper condensate return, it is recommended to install the humidifier below the steam distributor. Take care to provide proper steam line routing and proper condensate traps.
• Place the humidifier close to the steam distributor. Long distances reduce the output.
• The installation location of the humidifier should ensure it is kept out of reach of children.

Figure 9 – Location and Clearances

Mounting Procedure
Mounting template supplied with the humidifier.

• The humidifier is mounted using screw holes located on the rear of the unit.
• Ensure suggested clearances are met when deciding on the location and the unit is level.
• Use screws longer than 2 in (5 cm) if dry wall or other spacer is present.

Mounting the humidifier:

1. Locate suitable location for the humidifier. On the wall stud (2×4 or equivalent) or duct, mark the location for the key hole A (on the back of the humidifier). Insert a screw at A. Leave space on the screw to hang the humidifier.
   The humidifier will hang from this point.

2. Insert a screw into the location marked A. Do NOT completely insert the screw; allow space to hang the humidifier. Use a screw longer than 2 in (5 cm) if dry wall or other spacer is present.

3. Open the door to the humidifier. Remove the steam cylinder if it is installed. Raise and hang the humidifier on the screw A. Ensure the unit is level.

4. Through the inside of the humidifier, insert and tighten a screw into the lower mounting hole B. Tighten the top screw at A.

Water Supply Requirements

• Installed according to national and local plumbing code.

Water conditions versus steam cylinder live
The atmospheric steam output of the humidifier is pure and clean steam. During operation the dissolved minerals from the water supply are left behind in the cylinder. Many of these minerals will be removed during periodic flush cycles of the cylinder.
“Figure 15 – Water conditions vs. steam cylinder live and drain rates” generalizes the effect of water hardness, and demand on cylinder life.
Cylinder life is ultimately determined by the water chemistry, the unit running time, and output capacity setting.

Drain Connection

Drain Requirements
The Condair HumiLife RH produces hot water during operation. Upon normal drainage, the drain water is automatically cooled to 140 °F (60 °C).
IMPORTANT! Drain water may reach high temperatures 212 °F (100 °C) in cases where the supply water is not cold, or obstructed.

Considerations for the drain connection

• (Recommended) Drain line is made of a material rated to handle hot temperatures, 212 °F (100 °C).
• (Recommended) Use the drain line hose supplied with the humidifier. For longer runs, use copper pipe with the same inner diameter as the drain line hose supplied with the humidifier, inner diameter: 3/4 in (20 mm).
• Ensure that the internal diameter throughout the drain line is constant.
• Ensure that the drain line is adequately sized. A restricted drain line may result in higher mineral concentrations in the water and can result in poor performance.
• Ensure that the drain line is routed to a floor drain (or where plumbing codes permit). If the drain is far from the humidifier, use a condensate pump rated for hot drain water.
• Ensure that the drain line has a consistent, downward slope (1.2°) to the drain.

Electrical Connection

IMPORTANT! Wiring to be performed by a licensed electrician.
IMPORTANT! All wiring to be installed in accordance with national and local electrical codes.

Primary Power Connection

Figure 16 – High Voltage Connection and External Disconnect

IMPORTANT! Do NOT use the neutral wire as a ground. Connect a dedicated ground to Ground termination.

To install the high voltage connection:

1. Install a disconnect switch between the humidifier and the circuit breaker (for ease of maintenance).
2. Route the power supply wire through the strain relief located at the bottom of the unit (closest to front).
3. Connect the power wires to the main supply terminals L1, L2/N, and GND on the control board (terminal X1) in the humidifier.

Notes:

• Ensure that adequate power is available to carry full humidifier amp draw, as indicated on the specification label.
• A dedicated external fused disconnect may be installed between the humidifier and the circuit breaker.
• Do NOT use the neutral wire as a ground.

DANGER!
Danger of electric shock
The Condair RH is mains powered. Live parts may be exposed when the control compartment is open. Touching live parts may cause severe injury or danger to life.
Prevention: The Condair RH unit must be connected to the mains only after all mounting and installation work has  been completed, all installations have been checked for correct workmanship and the unit is closed and properly locked.
CAUTION!
The electronic components inside the Condair RH are very sensitive to electrostatic discharge. Before carrying out installations work inside the unit, appropriate measures must  be taken to protect the electronic components against damage caused by electrostatic discharge (ESD protection).

Controls
Condair controls are available as accessories and can be ordered with the purchase of the humidifier. If the controls were not ordered with the humidifier, they must be purchased from Condair, or be supplied by others. A relative humidity (duct) sensor is supplied with the unit.

Requirements:

• 18 AWG minimum
• Wiring kept as short as possible
• Cables for low voltage controls (such as humidistats, controllers, etc) should be routed through the strain relief at the bottom of the humidifier (closer to the wall/duct).

Considerations for installing external controls:

• Install the humidity control device in the return air duct (recommended) or in the room being humidified.
  A relative humidity sensor comes with the unit (a modulating or on/off humidistat is not included).
  Avoid placing near the discharge diffuser of humidified air, or in the discharge zone of humidified air.
  Install the device in locations that represent the room humidity (avoid areas near drafts, doorways, and sunlight).

• (Highly Recommended) Install an air proving switch upstream on the return-air duct to detect air flow.
  An air proving switch will prevent the unit from producing steam if there is insufficient air flow through the duct.
  Insufficient air flow during steam production produces excess and unwanted condensate in the air ducts.
  IMPORTANT! The humidifier must be connected to the furnace fan if an air proving switch is not installed. This ensures that the unit is humidifying only while air is flowing through your ducts.

• (Highly Recommended) Install a duct high limit sensor (or modulating or on/off high limit humidistat) downstream from the steam distributor and where the steam is fully absorbed under normal conditions to prevent duct  saturation. If RH reaches a predefined level – typically 90% – the high-limit humidistat disengages the humidifier. The high-limit humidistat is a very important safety device to prevent wet ducts if, for example, duct temperature unexpectedly drops and the air cannot absorb as expected.

• (Optional) Install an outdoor temperature sensor outside, in an area that accurately represents the outdoor air temperature, and NOT in a sunny location.
  Note: Condair humidifiers must have a closed circuit across its on/off security loop control terminals (labeled “SC” in the wiring diagram) to operate. Condair recommends the use of an On/Off high limit humidistat AND an air proving switch in series for this function.
  Note: All high limit controls should be ON/OFF type, and wired in series to the “SC” terminals on the control board.
  Note: The main control can be done using a relative humidity sensor (included with the humidifier), or with a humidistat (supplied by others).

The Condair HumiLife RH can be connected to the following devices:

• Air proving switches
• Humidistats or relative humidity (RH) sensors
• External fans
  » such as furnace fans, “enable” input (pilot duty only). External fans activate when the humidifier receives a call for humidity.

The humidifier is factory configured to operate under most conditions without the need for any changes.
If required, several settings can be made using jumpers on the control board.
For further information, refer to “Wiring Diagram” on page 21.

CHD-NA Control Wiring Without Furnace Connection

Note: This wiring configuration requires sensor change within Humilife App to “Open contact/Relay”.
Note 1 : Our system is a 2-wire accessory. Thermostats like the Honeywell T9 and the Ecobee provide dry contacts for wiring 2 wire devices. Systems like the Google Nest only supply a single wire connection so a relay is required for the thermostat to work.
Note 2 : If an external device is used for the humidifier they take complete control of the humidity with the unit. The unit will no longer control the humidity and cannot control the temperature setback as this is now done by the external controller. The app can only display canister lifecycle and error codes.
Note 3: If using a 3rd party device, always check the manuals provided with the devices in case of wiring connection changes or any other updates.
