IER Positioning & Mounting
General guidelines for positioning
IER electric steam humidifier should be posioned so that:
Length of the steam line (or hose) is as short as possible,
In case steam hose is used, the bend radius of 12in (300mm) is ensured
Humidifier is easily accessible for service
CAUTION. Risk of malfuncon due to vibraon. Do Not mount IER electric steam
humidifier directly on venlaon duct.
CAUTION. Risk of flooding. Ensure that the local where IER electric steam
humidifier will be installed is equipped with floor drain.
In case of no floor drain is available; installaon of a water leak detector is required
in order to prevent any flooding in case of abnormal operaon or service.
IER electric steam humidifier should be installed in a well-venlated and dry environment.
If local is subject to below freezing point temperature, acvaon of ant freezing funcon of
the IER electric steam humidifier is required.
For outdoor installaon please contact your steamOvap representave to order and install
special outdoor oponal enclosure for IER.
IER maximum ambient condions:
Temperature: 41°F to 113°F [+5 to +45°C]
Relave Humidity: 90%RH max (non condensing)

There is no minimum clearance on both side of the IER humidifier, but it is a good pracce to
have a clearance of 4 to 8 in [100 to 200mm] for ease of installaon and service
Allow a minimum clearance of 24in [610mm] with floor to allow for proper drain slope and
drain pipe column.
Front clearance of 30in [762mm] is required for access to the IER humidifier

General guidelines for Mounting
CAUTION. Risk of malfuncon. IER electric steam humidifier must be levelled
in X & Z axis.
Installaon on wall (without mounng bracket)
1. Verify that wall structure and strength is appropriate to support the operang weight
of the IER electric steam humidifier.
In case, the wall is not solid enough to support operang weight of IER electric steam
humidifier, install humidifier on the floor stand (FS opon is available to your
steamOvap representave).
2. Mark the wall or support according to the above holes locaon, and drill 4 holes to the
wall or support as per the size of anchors and/or screws.
3. Use anchors of sufficient size (at least 1/4in [6mm]). Insert those anchors and the 2 top
screws, ensure that the screw heads extends 1/4in [6mm] from the wall, so that the
IER electric steam humidifier will be able to be hung on those 2 screws.
4. With front cover removed, hung the IER electric steam humidifier onto the 2 top
screws.
Insert the boom screw through the back plate of the humidifier and into the anchors
in the wall.
Ensure that the humidifier is properly levelled.
Tighten the 3 screws. Re verify the level in the 2 direcon X and Z axis.
5. Re-install the front cover to the humidifier.
6. Oponal Mounng bracket (opon MB) is available to your steamOvap representave
in order to ease up wall mounng process.

Installaon on wall (with mounng bracket – opon MB)
1. Oponal Mounng bracket (opon MB) is available to your steamOvap representave
in order to ease up wall mounng process.
2. Verify that wall structure and strength is appropriate to support the operang weight
of the IER electric steam humidifier.
In case, the wall is not solid enough to support operang weight of IER electric steam
humidifier, install it on a floor stand (FS opon is available to your steamOvap
representave).
3. Mark the wall or support according to the above holes locaon, Drill holes to the wall
or support to aach the mounng bracket to the wall as per the size of anchors and/or
screws.
Distance between the 2 holes in Mounng bracket is 15in [381mm]

Figure 11 – Installaon with Mounng bracket
4. Use anchors of sufficient size (at least 1/4in [6mm]). Install the mounng bracket to
the wall or support.
Ensure that the mounng bracket is properly levelled.
5. With front cover removed, hung the IER electric steam humidifier onto the mounng
bracket.
6. Install the 2 supplied screws to avoid the IER humidifier to move up from the mounng
bracket.
Installaon on Floor Stand (opon FS)
1. Ensure that the floor structure and strength is appropriate to support the operang
weight of the IER electric steam humidifier.
2. Aach the floor stand to the floor or structure to avoid any movement of the IER
electric steam humidifier.
You can use bolt or screws to aach this one to surrounding structure or to the floor.
3. Install Humidifier (with front cover removed) on the floor stand and secure it with
supplied bolts.
4. Re-install the front cover to the humidifier.

Water supply temperature: 37 to 105°F [3 to 40°C]
IER electric steam humidifier can accept a wide range of water quality.
Untreated water will lead to scale deposits that will need to be regularly removed from steam
chamber.
Use of addives such as scale inhibitor or corrosion inhibitors, disinfectants or other can
impair the normal operaon of the humidifier and are not allowed.
Water supply conducvity: 1 to 1500µS/cm

2. If IER humidifier is supplied with tap water it is recommended to install a 10µ sediment
filter on the line. This filter will protect internal water fill valve from clogging.
3. A flexible braided hose is supplied (for the single module IER) for an easy and secure
connecon to the water supply inlet.
